Outlines

00:00

😔 The supercharger kit ruins the car

The supercharger kit initially made the car sound great, but then it started running worse progressively until it sounded terrible. The author is determined to fix the issues and get the supercharged M3 working properly.

05:03

👨‍🔧 Attempting repairs and modifications

The author tries replacing the battery to fix the issues but it doesn't work. He gets an exhaust installed while still troubleshooting. The car misses the tuning deadline because the issues aren't resolved yet, so they go to a performance shop seeking help.

10:05

🤦‍♂️ Finding a silly mistake

The performance shop finds issues with the supercharger wiring done improperly. Also a coil pack is split, causing cylinder misfires. Fixing these silly mistakes solves the running issues.

15:06

🔧 Preventative engine work

The shop replaces the rod bearings as preventative maintenance since there's no service history. The old bearings are very worn. Reassembling engine and subframe after the work is done.

20:07

👨‍🔧 Correcting supercharger installation mistakes

Before dyno tuning, the shop finds many more supercharger installation mistakes to correct. Tightening things up before moving forward.

25:12

💪 Finally tuned to 612 HP

After sorting issues, the car is dyno tuned and makes 612 HP. There are plans for more content on the supercharged M3 build.

Keywords

💡Supercharger

A supercharger is a device that forces extra air into an engine's cylinders, allowing it to produce more power. In the video, the presenter buys and installs a supercharger kit on his BMW M3 sports car. However, he struggles to get it working properly at first. Fixing issues with the supercharged M3 is a central theme throughout the video.

💡Dyno

A dyno, or dynamometer, is a device used to measure the power and torque produced by a vehicle's engine. At the end of the video, the presenter takes his supercharged M3 to a performance shop to tune it on a dyno. It produces over 600 horsepower on the final dyno run.

💡Rod bearings

Rod bearings connect the engine's connecting rods to the crankshaft. BMW M3 engines are prone to excessive rod bearing wear. As preventative maintenance, the presenter has the rod bearings replaced while the engine is being worked on.

💡Coil pack

A coil pack provides high voltage current to an engine's spark plugs. At one point, the presenter finds a split coil pack, causing some cylinders to misfire. This was likely responsible for many of the issues in getting the supercharged M3 running properly.

💡Exhaust

After installing the supercharger, the presenter upgrades the BMW's exhaust system. This includes test pipes to improve airflow and allow the engine to produce more power. It also makes the car significantly louder.

💡Tuning

Tuning refers to customizing the programming of a vehicle's Engine Control Unit (ECU) to change performance characteristics. Proper ECU tuning is essential to optimize power gains from modifications like adding a supercharger.

💡Fault code

Fault or error codes help identify issues with a vehicle. The presenter initially gets a fault code pointing to ignition problems, likely caused by the split coil pack.

💡Subframe

The subframe is a structural component that the engine and suspension connect to. To access the engine internals and replace the rod bearings, the shop has to remove and later reinstall the subframe.

💡Power output

The key performance metric for the modified M3 is how much horsepower it produces. On the dyno, it makes over 600 horsepower compared to the 425 hp output from the factory.

💡Fuel injectors

More powerful engines require larger fuel injectors to supply sufficient fuel. The tuner recommends upgrading the stock fuel injectors to maximize the power potential of the supercharged engine.

Transcripts

in the last video you saw us bought a

supercharger kit onto my e92 M3 but all

it did is ruin it even though when we

started up the first time it sounded

mint she's

running oh I happy that then every time

we started it after that it got

progressively worse until it sounded

like

this but I'm not the sort of person

that's going to give up that easily I'm

determined to finish this video with a

working supercharged M3 especially after

all the hard work that me and Ethan have

put into this car already so we need to

knuckle down and do some research and

find out what could possibly be wrong

with this car because until we get to

the bottom of this issue this M3 is

going nowhere so realistically we need

to fix all of the faults that we've now

got on the e92 M3 before we can get it

tuned so we managed to get the faulty

OBD Port working temporarily with the

OBD1 reader and it came up with the code

27 b0 and that comes to quite a few

things which could potentially be I've

got the answer to the problem

reliability fixed

wow once we've got this car reliably

starting every single time and running

up to temperature we can send this car

for tuning because we all want to hear

how this supercharge is going to sound

that's it it should start now fix

definitely start now so the first thing

that I'm going to try is swapping out

the battery I know this might sound a

bit nuts but if there's one dead cell in

the battery apparently that can play

Havoc with well everything so this

battery has been dead we don't know how

long it's been sat in the salvage yard

so I just want to rule that out and make

sure it's not going to be a problem so

I've picked up a new one from BMW which

cost the same as everywhere else and

let's put this in get it coded into the

car and then that's that problem if it

is a problem done so very quickly I can

swap over the battery and code the new

one in but I'm not hopeful this is going

to fix my

[Music]

problem it's running better than it has

before but it's definitely still not

right let's turn it off so I'm still

scratching my head on what could be

wrong with the M3 we've only got a v

fault code given us no real indication

as to what's wrong with it and an

intermittent inconsistent running fault

she's still not running right but what

do you do while you're waiting to get it

working you modify it so we've got the

guys here from modstock who are going to

be putting some test pipes on and also

their back box mod which is not only

going to make it sound better but also

mean that when it comes to tuning we're

not going to have any issues there so

you are your two and half pipe and um

yeah it's going to be loud and test

pipes okay well I think the car suits it

the supercharged car we've already gone

given up with the OEM side of thing so

it may as well go a bit asbo and I think

that's what it deserves so the 2 and 1/2

should be loud but not ridiculous and

then the test Pipes make it a little bit

louder too oh they look good don't they

little mod stock I like it very nice

these guys also do resonated test pipes

as well but what we're going for is the

standard version because just because so

we need to get this car in the air and

then we can get underneath and start

modifying this

exhaust

so the guys from modstock can get

underneath the car and start working on

taking the old exhaust off by unplugging

the lumber sensors and unbolting it from

the

car and before I could even blink

they've got the center section

[Music]

removed and now that that's off they get

straight to work on removing the back

box

[Music]

too

and it's a good job that we're doing

this because as you can see here there

is actually a crack in the old Center

section of the exhaust but luckily

that's exactly where we're cutting it to

fit the new test pipe so it won't be a

[Music]

problem so this is something we see

really really often um so oh damn yeah

damn but it's nothing some nice shiny

new clamps can't fix but now it's time

to look at the back box this is the old

one which came off the car and we're

going to be replacing this with Mod

stocks 2 and A2 pipe mod essentially

these guys modify an original bat box to

make it sound better I've gone for a 2

and 1/2 pipe mod but you can go up to

four and the more pipes you go for the

louder it

is but they've now got the test pipes

fitted with the lambor sensors as well

and they can start bolting that back up

to the

car doing the test pipes is essential

for what we're doing cuz we've got to

free up extra flow in the exhaust to

allow for the extra power that the

supercharg is going to make and for me

modifying the rest of the exhaust is a

must because I want to hear that V8

scream now that Dean and Chris have got

the center section fitted they can start

fitting up the rear section and the back

box as

[Music]

well the bat box is now on and you guys

can't really see a difference but one

thing you are going to see a difference

with is the tips and we are going for

Boom the new FS series style carbon M

performance tips which look naughty so

we're going to have four of these poking

out the back they're going to be sat

like that so it looks like a wheelbarrow

and yeah it should look pretty sick so

let's get those on and very kindly the

guys at modstock have also offered to

give you guys 5% off any modified

original exhaust systems by using

discount code slick 5 when getting in

touch with them via Instagram all of

their details are going to be in the

[Music]

description so the guys have just

finished off on my exhaust and

unfortunately we can't hear it at this

point because it's not running the best

but my mate has just had exactly the

same back box mod but minus the test

pipe so we can hear his

[Music]

instead

damn what's your

thoughts very good but as good as that

sounds it doesn't take away from the

fact that the M3 is still broken and I

completely lost track of time modifying

my car meaning that I've actually missed

my deadline to get this car working

again and as good as this exhaust looks

it just doesn't fix that but the only

hope we have is the fact that we've come

to a re performance to get this car

tuned and I'm praying that they can help

us get to the bottom of this running

problem before this car hits the dyno

later today and we are now officially

out of time we're at our deadline where

we need to get this car in for tuning

and Ethan from stealth movements has

brought us down to Norwich or is it

kingslin kingslin with the M3 down to a

Reeve so we can now get this car

unloaded and hopefully get to the bottom

of this running problem and then we've

got some serious work to get to on this

[Music]

car

[Music]

Big East if anyone wants a car moving

where do they go uh stealth movement

mate how do they get in touch with you

uh Instagram Facebook and there's a

contact number and all information is

getting contact on there is it all going

to be in the description all in the

description my man nice so we are tight

on time with lots of work to do and also

some faults to figure out nice work eth

smashing it and I'd be lying if I said

at this point I wasn't worried but

something tells me when I walked into

this place my car was in the right

[Music]

[Applause]

hands I've never even seen a

supercharged M3 In the Flesh before and

then coming down to a Reeve and they

being a workshop full of them just fill

me with confidence that we might

actually be able to get this fault

fixed

[Music]

she don't sound healthy it doesn't sound

good does it sounds

perfect so not only are we about to get

our work inspected we're about to be

ripped to shreds Yeah man so Mr Aaron

reev himself and his team set up on my

e92 M3 and started trying to find what

this fault could be what's your first

thoughts

um and very quickly they started to find

quite a few things we did wrong in

stalling this kit that should be behind

that okay we got that wrong we were

trying okay we were working off 240p

instructions we may have wired this

wrong as well yeah it was it was it was

guess work I can't lie the white wire

with a red line yes and then that well I

have Earth that there and then well

that's why we're here we've come to the

pros for a reason we gave it a good

shoty we gave it a go these SP plug

covers off intentionally no we just

forgot to put them on and then couldn't

get them in you can't you can if you

just cut a little square out okay maybe

that's a good idea if you had to on

first glance rate the install out of 10

what would you give it

[Laughter]

two wow maybe we didn't do as good a job

as we first thought have you found

something uh there's there's no spark to

any of these four cylinders all um it

look at the live data it's just shut off

the spot completely so receiver and up

could be a wiring fault can be a Vanos

fault as well but they sometimes with

these with like Vanos FAL and stuff

they'll go into limp mode but they don't

even know why the ecus aren't

sophisticated enough to know that but

you are yeah so using his wealth of

knowledge Aaron starts digging around in

the engine bay checking the spark plugs

checking all of the basic things that

potentially could cause this fa and it's

something that none of us even predicted

it was something so obvious and in your

face that it's almost daed well I think

it's safe to say sometimes I do make

stupid mistakes and do you know what it

happens to the best of us but the funny

thing is it didn't go like that when I

pulled out I told you to pack this in

your

suitc so one of the coil packs is

literally split in half it didn't pull

apart when I pulled it out but I think

that's pretty safe to say that's going

to be our issue isn't it I'd say so yeah

so um where's the bin

now that's sorted hopefully we can push

forward can't we well I'm just want to

let you guys know that that is my side

of the engine and this is Chris's and

which side's the plug broke on I broke I

broke the call p apparently but if

that's what we found already with this

car I think it's only going to get worse

from here can't wait to see the

rod and it really was a silly little

mistake sometimes it's so easy to miss

something that's potentially so obvious

but something so small can cause big

problems so I'm glad managed to find

that but now it's time to test it and

thank God it's all working fine now and

the car is running on all cylinders well

silly mistake job done but easily found

they're the best sorts of mistakes

because they're cheap and they're easily

fixed but there may be other problems as

well we have found one other thing as

well the tensioner looks like it's not

working properly on the new belt so we

to get a new tensioner on there to make

sure the belt's not flapping around so

now it's time to get the car up in the

air and have an inspection underneath

before we went on to the next job and

these guys are actually pretty impressed

with the condition of this car

especially considering the mileage and

how original everything looks on there

as well to get these from they are mod

stop so say what you want cuz apparent

he's a friend of yours no I'm just

saying God say it and this next job is

one that I needed to do saying goodbye

to 300b worth of oil because e92 M3s

have a common problem where the rod

bearings wear excessively which can

cause catastrophic damage to the engine

and the first step to do doing these is

draining all of the oil out the car

including out of the oil filter housing

as

well right some people in the comments

were telling us that these bolts where

we had bolts in our oil filter housing

which weren't supposed to be there Aaron

what did you say to those people in the

comments uh they need to read the

workshop manual nice these bolts are all

part of the pressure relief valve for

the or filter so obviously they are

meant to be in there um they are perfect

ly not that somebody's randomly left

some bols in there so now it's time for

the bit you lot have been nagging me

about and of course I was going to do it

if we're supercharging this car it be D

not to we have no history on the car at

all so this is where we're going to

start doing the rod bearings and it's a

common failure point on these cars

supposedly isn't E Yeah clatter clatter

bang bang so we need to take off the

subframe we've also

got some crusty power steering lines to

change as well so we're going to get

those done at the same time cuz it makes

sense subframe off some off and let's

inspect these bearings go these rapid

because if these bearings went it could

cost me an absolute Fortune just like if

you were buying a car that you didn't

know had hidden history but we nearly

ended up with a crash damaged camera

teers that's why whenever you buy a used

car make sure to check it out on car

vertical because not every seller is

100% truthful and honest and now all the

arms are disconnected that means that we

can start taking away to the engine and

whilst we're doing that let's take a

look at an example of a report that you

wouldn't want to see when you're

checking out a car so you can see here

this f8 M3 has a green tick for mileage

Finance but an Amber warning for damage

and as soon as you scroll down to the

photo section you can see exactly how

badly it was damaged with huge damage to

the passenger side and all of the

airbags going off if we continue

scrolling we can see the car has never

been stolen and also all of the mileage

checks out and then worst of all if we

go down again we can see on the damage

section that this vehicle has been

marked as a category B right off meaning

it can never go back on the road and

it's only useful for salvageable parts

but my favorite part of car vertical is

the timeline they give you we can see

here when the car was made and when it

was crashed only a year later mean this

car hasn't been on the road for long so

to check out your car a friend or family

member's car or a car that you're going

to buy make sure to do it with car

vertical using discount code Chris to

save some money and as predicted this

engine mount looks shot but stayed in

one piece this one has completely left

the chat it's gone in off so that is why

we replace them when the sub frame comes

off next thing to come sump after we had

a clean up down here so me and Ethan

started removing all of the T30 bolts

which hold the sump in place and there

is a lot of them but after we got all of

those out it was ready to come off I'm

going to go ready got it one down she

comes oh god oh goly gosh oh she

drippy M gloops nectar and then the

final thing to remove is the oil pickup

pipes so these obviously take oil from

the sump and then pump it around the

rest of the engine but these need to

come off so we can get get to all of the

bolts which we need to get to in order

to change over these rod bearings so now

we have done all of the leg work and

we're going to leave the proper

intricate stuff to the master because I

know for a fact I would mess this up I

would get this wrong somehow I'd do

something stupid I don't think it's

actually too hard is it it's pretty

simple not that but if you get it wrong

you get it really wrong so Aaron

delicately starts removing the end caps

from the

rods

and with Precision like open heart

surgery he replaces those rod bearings

but something tells me that he's done

this job so many times he could

practically do it with his eyes

[Music]

closed no point crying over spil

te now one of the things which makes

this job take a while apart from the

fact you have to be meticulous is that

these new bolts need to be torqued and

undone three times before they can be

fastened up for the final time

new bearings are in but the question is

how bad were the old ones well we're

about to take a look and we're getting

them all laid out here now typically the

ones at the front of the engine are not

as bad as the ones at the back so here

we go this is for cylinder 1 is that the

Right freeze cylinder one so you've got

the lower part of the Bear in there and

then the upper part the upper part as

you you can see here has obviously take

more of a wear that's the part that's

against the crankshaft and takes the

main frust of the crank obviously as the

crank goes up the rod goes down is

taking the main loading of it if we just

go the other way to cylinder 7 you can

see this bearing is severely quite worn

this is an LCI car which has tin and

aluminium bearings BMW changed the

material compound of it contrary to what

people seem to believe on forums BMW

never improved the bearing design of

these cars ever since they came out the

bearing clearance is exactly the same

the material changed but that makes no

odds but yeah just goes to show it's

definitely worth doing these I mean it's

a preventative thing but we don't think

that subf frames ever even been off that

car so these are completely original

they're the original bearings so yeah

120,000 Mi but I think it's not had a

hard life but they they need changing

any thoughts

eth

wow so many facts here this is this is

intense so with the old rod bearings now

removed and I'm so glad we did this even

as a preventative measure if we didn't

do this you can see how worn they are

and this could have caused irreparable

damage to this engine but we now have

the new ones in so all we've got left to

do is reassemble the engine and the

subframe and then we can get this car on

the dyno and get it tuned and hear that

supercharger

scream so we can give the sump a good

clean down in the parts washer followed

by a new sump gasket sump bolted up new

rod bearings inside now what's it time

for Ethan pull-ups on my car apparently

so you tip the whole thing over big boy

so now we need to get the subframe back

on I think we should clean but first

before we do that we need new engine

mounts because the old ones well they

were they're done they were they were

bad but we don't want to go back to OEM

we're going to upgrade these for some

lovely power Flex ones which are going

to last forever and ever

so we have new power Flex bushes to go

in and correct me if I'm wrong but these

holes here are for these pins so we can

adapt the stiffness of the Bush

depending on how many pins we put

in pinch and

roll so with the pins fitted and the

subframe cleaned up where the old engine

mats were we can now fit up these new

nice power Flex ones it's just another

job which makes sense to do while you're

here and these new power Flex ones are

going to last much longer than an oem

Bush and now those are in we can fit up

the subframe and steering rack

[Music]

again and with that now refitted we are

finally getting somewhere the sub frames

on the rod bearings are in and

everything is starting to slowly take

shape so we can now attach all of the

arms and trap rod ends and then it's

back up top to have a look over the

supercharger before this car hits the D

it's safe to say the professionals

weren't impressed stupid so we're done

underneath and before it goes on the

dino we want to make sure that me and

Ethan have done this right so we' pulled

the plum off and how much stuff have you

found that isn't right about about 80%

about 80% of what me and Ethan have done

his wrong nice we left a vacuum pipe off

we rooted K hoses wrong what else well

yeah the wir yeah so we've got some

Tiding up to do first is what you're

saying oh yeah I wanton take long yeah

we tried our best the instructions

weren't the clearest but you know we got

it on even if we did do alph ofit wrong

so then we went about Tiding up all of

our

mistakes and also fitting a new Reser

valve because this one's pretty old we

want to make sure it's going to work

perfectly so we know this new one is

going to be spot on and not only that it

actually looks better as well so then

the final thing to do is fill the car

back up with all its fluids so all

wheels and power steering fluid and

coolants and then it's back on with the

wheels and with those talk to spec it's

Dino

Time speed stop I don't know are you

feeling ready I don't know I'm not

feeling ready but we' got all the fluids

in the car now Aza we're ready you're on

it big man we'll be fine you go for

first is the key in there yeah yeah okay

here we go tense

music

you hear that

hard so first we crank the car over a

few times to generate oil

pressure and then it's time to go for

that first proper

start damn God damn she sounds good that

woo and she's running not being lumpy

with no tune on like Aaron said

originally rule number one of getting

your car tuned is remember to put fuel

in it so don't be a dipstick like me and

if you haveen any car tuned go with some

99 just have to run off and get some

fuel so after hours of hard work already

in this car going over some of the

maintenance stuff and also me and Ethan

fit in this supercharger to to begin

with it's time to see if all of that

hard work is finally paid

off so we can clear some space and move

some cars out of the way so we can get

my e92 M3 on to Aaron's maraha

Dyno but everything to do with this car

so far has been a risk buying it in the

first place on 120,000 Mi with zero

history and then fitting a supercharger

to it I really have put my faith in this

car Aron is this the worst conditioned

car you've ever had in your

Dyno probably got less bits than

those but I'm praying underneath this

slightly tired and battered body beats a

heart of pure gold because it's about to

get some abuse on the dyno and I've got

to thank Aaron Reeves so much for

letting us come down and film here and

also helping us out with doing some of

the work on this car and he also wants

to help you guys out at home as well so

he's offering you guys £100 of having

your Rob bearings or a supercharger fit

into your car and to redeem that all

you've got to do is quote Chris slicks

when you're contacting them I'll leave

all the information in the description

and now with all the cooling fans in

place we can strap the car down and we

can see what this car is going to

do we are now loaded up onto the Doo and

how sick is this dino by the way just

like to say but it's the moment of truth

let's see whether this e92 is going to

survive or not I'm giving it a 50/50

chance at this point so the first thing

to do is Flash the base tune onto the

ECU followed by warming the engine up

and the gearbox on the

[Music]

dyno how we

looking good just getting it ready to L

I have no idea what he just said I know

and now it's finally time for the first

run here we go big man are you ready

yeah man

I think it's broke oh no you got a Miss

fire on 7 and eight oh dear same oh

ignition disabled 7 and eight and we're

already running into problems does a

dino r ever go to

plan probably not we've got a misfire on

cylinder s and

eight it does look dirty that and it was

the same faults that we had before when

we had the broken coil pack but this

time on the other bank but we've already

changed over all the coil packs so we're

praying just tightening up the Earth

does the job and makes this car run

right but let's find

[Music]

out

[Music]

and though he reached the red line that

I hope you that's the problem fixed and

thankfully it was the car run perfectly

that time so we can now do a few more

runs and start finessing this

tune

that's a base map she got more yeah

should do cuz if this is the older red

injectors obviously they have a a lat of

how far they'll go I'd expect this to do

just over 600 on this pulley as well

over 600 in a e92 M3 that's a

beast he jaly no I'm coming for you this

car is now a beast but I think we've got

one more run left in

[Music]

[Music]

it

[Music]

so that's the final run completed so as

the car came down the revs it was time

to finally see what that final power

measurement was let's see what she's

made oh damn

612 oh me 612 horsepower what a car what

a car could you ask for much more out of

an M3 that is sick there is one thing

which we need to do with this though
