Q & A

What event is the video about?

The video is about the team heading to Sick Week, an annual drag racing event held in Orlando, Florida.

What modifications were recently made to the car's engine?

The car recently got a new Texas Speed 388 cubic inch engine along with some other drivetrain component changes like a new torque converter and transmission fluid.

What is the purpose of the first test run?

The first test run is meant to be a partial pass to get data on the new engine and component combination and ensure everything is working properly before trying to go all out.

How much boost pressure was the car making on the faster runs?

On the 755 @ 185 mph run, the boost pressure ranged from 25.5 psi to 27 psi which is lower than expected.

How did the new engine setup compare to previous builds?

Compared to a previous 193 mph run, the new engine had better performance early on with higher boost, RPM, driveshaft speed and G-meter readings.

What was the top speed achieved in the video?

The top speed shown was 185 mph on a 7.55 second quarter mile pass.

Were there any issues encountered during testing?

No major issues were mentioned. The engine appeared to perform well within targeted parameters.

What is the plan for the following day?

The plan is to get some food, load up the trailer, head to the hotel to edit video, and return the next day hoping for improved weather and track conditions to make some faster runs.

What safety gear was being used?

The driver had on a new Stilo helmet with integrated radio communication headset to talk with his crew member.

What potential is there for future performance gains?

Since the engine ran 7.55 seconds on only ~26 psi of boost, there is likely room to safely increase boost and potentially run in the 7.4s while still using the stock bottom end.

Outlines

🛬 Preparing for and traveling to race event in Florida 🏁

The video host and crew pack up their race car and drive from their shop overnight to Orlando Speed World Dragway for a racing event called Sick Week 2024. They arrive late and have to wait in long lines for inspection and registration due to arriving late.

05:01

😴 Waiting through delays from rain and tech inspection

After waiting hours in line, it begins raining at the event. The host must wait even longer through the rain and finish going through tech inspection before finally being ready to make test runs with their race car.

10:02

👨‍🔧 Testing the newly built race car 🏎️

With inspection complete, the host test drives the newly built car to check the transmission and make adjustments to the tune. After a couple partial test passes, the car performs well and is ready for an all-out run.

15:08

🎉 First full race pass is a success!

The host completes his first full-throttle pass in the new car, achieving a fast time that meets his goals for only using low boost pressure. The engine performs extremely well for how little boost it used.

20:36

🏁 Getting food and preparing for next day of racing

After a successful first day of racing, the host recaps the runs, loads up the car, and heads to his hotel. He plans to get food, edit video, and prepare for even faster passes the next day.

Keywords

💡Drag racing

Drag racing is a type of motorsports racing where cars compete on a straight quarter mile track. This is the main activity shown in the video, with the people in the video preparing a car for drag racing events. Examples from the script showing this include mentions of the drag strip, races, runs, and passes.

💡Tuning

Tuning refers to adjusting or configuring parameters on the car to optimize its performance. This includes things like engine tuning, transmission tuning, etc. The video shows the process of tuning the car between passes to improve aspects like boost pressure, RPM limit, etc. based on data from previous runs.

💡Data logging

Data logging means recording sensor measurements from the car during a run, like engine RPM, boost pressure, etc. This data is then analyzed to see how the tuning changes impacted performance. The people in the video review the data logs after runs to determine if more tuning changes are needed.

💡Boost pressure

Boost pressure refers to the air pressure generated by the turbocharger being forced into the engine. More boost pressure allows more air/fuel mixture into the engine, generating more power. The video shows the team tuning the boost pressure through multiple passes, increasing it gradually to optimize performance.

💡Test passes

Test passes refer to partial drag strip runs done not at full power, in order to test some aspect of the car before going all out. The video shows several test passes being done to check tuning or specific parts before attempting full power runs.

💡Build progression

Build progression refers to gradually modifying and upgrading the car over time to improve performance. The video talks about engine upgrades, transmission work, etc. done since previous races, showing the ongoing process of modifying the car.

💡Parachute

The parachute is deployed to help slow the car down after high speed runs. There is a shot of the parachute being deployed in the video, as the car reaches speeds over 180 mph.

💡Eliminations

Eliminations refers to bracket racing where cars compete head-to-head in an elimination tournament. The video mentions planning race strategy around the eliminations and weather on following days.

💡Diagnostics

Diagnostics refers to checking over car systems to identify any problems. The video mentions looking for leaks, checking pressures, temps, voltages etc. after runs to diagnose issues.

💡Race prep

Race prep refers to all the tasks done to prepare the car before an event, like maintenance, loading it into the trailer, tech inspections etc. The video shows extensive prep work done at the shop and also at the track before racing.

Transcripts

all right everybody good morning and

welcome to the ksr YouTube channel it's

uh kind of

early but uh we are leaving the

shop about to hop in Will's truck and

take off with soccer mom headed for sick

week in

Orlando late night last night but cars

in the trailer didn't die to it like we

were thinking we were going to but

will laughs cuz I thought we'd be on the

dyno before like 10:00 nope didn't

happen wasn't even

close sometimes I'm too optimistic for

my own good I don't know if you can see

me or not maybe not all right let's uh

let's get to the racetrack

and see what we can

do

[Music]

all right well we have made it to

Orlando Speed World Dragway kind of

crammed oursel in between some people

that have parked their Rigs and already

gone up to start the

event and uh there's a lot of people

here we're going to get the old soccer

mom

unloaded go head up to Tech and then

hopefully get in line and get a run or

two or three today cuz uh the engine has

never seen wide open throttle we'll do a

two-step check here in a little bit too

once we uh get her

out all that stuff so but first get

unloaded and then go to

Tech we are rolling to the techline

which I

believe wraps almost all the way around

the racetrack right now so here's Tech

but the actual Tech is somewhere way

back there a half mile away away so I've

got about a mile of techline to wait

through that's what we get for getting

here

late oh well what can you

do might need to get some gas by the

looks of that little red uh red block

right

there oh

well

well we're moving we were down there and

now we're right

here and I'm

uh battery's almost dead I'm have to

walk back to the trailer and get a

battery shoot down here eating some

breakfast ketchup flavored lace potato

chips not available in the United States

but apparently it's a Canada

thing and it's good really

good yeah sounds weird but really good

yeah thanks Rich Canadian Chuck Norris

brought us brought us some down

so well another 2 hours maybe we'll be

ready to go make a

run well I don't know if you can tell on

the

video but it's

raining welcome to Florida but better to

get it out of the way

today than the rest of the week which

the for weather forecast looks pretty

good for the rest of the week so you

know hopefully it will

be and hopefully this is as heavy as it

gets so I guess we'll uh suffer through

it and see if we can get up to the tech

Barn I ran back to the trailer in the

rain to get a new battery for the

camera cuz you know you guys needed to

know it was raining

today I'm tired I might be a little bit

delusional

today you guys bear with me all right

well we have made it from all the way

down there where you can't hardly see we

probably

have about an eighth of a mile to go and

unfortunately you can kind of see the

water coming off the tractor

there but by the time we get through

Tech probably

be ready to go

race that's my prediction we'll see so

we do still need to do a spool test once

we get to the back to our

pits I've already gone through and kind

of built a boost ramp

that's partially based off some runs

we've made earlier since it is a 388

again use some of the runs we've used in

the pass although after 4 seconds I dro

the Boost to zero or at least the Dome

pressure to zero to try and prevent me

from sending it all the way out the back

door on the the first

pass so that's where we're

at well probably hold off on the next

part of the video till we get into

Tech all right well we are through Tech

all inspected I think oh yeah we got our

number so we're we're good to move but

uh there's our new number a 51f if you

guys want to follow along with us on the

live timing and I think I think the live

stream's a little bit delayed because of

the rain but we'll see but uh now it's

time to finish registration and then go

get ready for a

[Music]

Runo all righty well we're through Tech

starting to turn the car around for

making a run down the track going to try

a spool test and see see how it

does this new combination and new parts

and everything's been pretty happy so

far so I think my old tune is going to

work but I guess we'll

see

seemed like it worked to

me all right we're going to try one more

that spooled well but the Boost kind of

was coming up kind of slow still even

when I lift it off so I'm to I've

changed the offset for the rev limiter

to where it's going to make more boost

before it drops the RPM so you may hear

it and come down so we'll see uh see how

it

[Music]

works you doing do it

again

here H up in a little bit yeah so that's

that should give me the data I need to

that should give me the data I need to

figure out exactly what I need to

change so I'm trying to Target like 9

and 1 12 10 lb so whenever the RPM went

back up it had falling below uh 9.8 lb

of boost so see what we got going on

here and then we'll be ready to go to

the starting line all right everybody

well got me a new helmet and uh been

wanting one of these steelos for a long

while and it's got Electronics built

into it and actually right now I'm able

to talk to will over here through the

headset and he's plugged into a car

harness right now that runs down

to the rugged Radio setup

here and when we're going down the road

we will both have headsets on if we want

to we can listen to the radio we can do

all kinds of stuff and uh pretty cool

kind of put one of these back in mullet

years ago and actually had one in a nail

truck when I was running it and it's

pretty awesome but uh yeah this is be

able to listen to some talk to each

other

better good deal I'm ready to go

[Music]

racing all right we're rolling up for

pass number one at least I think we get

to roll

up we heard uh them announc some cars

come to the lanes and it was either a

class radio or C-Class radio was really

hard to hear so hopefully we're about to

make a

run either way we're going to stay up

here until until it is our turn to run

if it's not our turn to run

any it's time to go fast actually to be

honest with you guys I shut the Boost

controller to zero at 4 seconds so I'm

not going to be able to go that fast

which is keep me from uh going all the

way to the Finish Line we want to make a

short run look at some data and run uh

look over the car look for leaks look

for all that good stuff

so here we

go all right we're buckled in for first

run of s week

2024 following Alan

Whitaker's absolutely amazing money

Carlo this car is like that that thing's

good it's a show car that goes really

fast so got a few cameras we got that

one we got one back there

somewhere and one on the back of the car

so hopefully they all stay

recording try to give you guys some

decent footage for this week

but this is like I said earlier going to

be a partial pass it's kind of a little

40 through 60 ft I think know it's hard

to tell with all new stater in the

converter new uh new

engine so we'll see see what it does and

then take that data and come back for

run number two in a little

bit

[Music]

come I can run out

stand

at5

woo that wasn't

bad tell you what felt pretty good even

though it was pretty slow it look good

coming down through

there all right well great first fast

get the Jitters out of the

way everything worked well the radio

worked chatting with li while I was Road

coasting down the track the uh boost

shut off basically feels like the thing

blew up but obviously it didn't

everything's happy only 6 lb of coolant

pressure

right I think we'll just look at some

data compared to some of our earlier

runs and see what we need to do

to leg her out a little further next

time and uh if we can get a good maybe

one good pass all we might just put this

thing in the Box for

today all right real good early first

pass 127 332 507 at

130 so uh I'm going to go compare that

to some of our other runs

and see what we need to do to leg it out

a little further maybe I don't know I'm

just happy to be

racing

[Music]

two pretty

solids

the so again me set the stage for test

the

1970 made the toe all the way out from

California to be

here in our street bre class that is the

class designed for engines less than 6 C

or diesels

car has been hit the 90 bracket I'm sure

you would like to see an 8.9 something

po up on the board inside

gas

yeah

at the 750 run tomorrow in the better

weather going on

radio

woo

[Music]

[Music]

yeah

baby that was a good run hopefully you

guys like the parachute

[Music]

shot all right everybody well for a

879 I'm uh really excited about what

we're seeing in the

data uh with these were used spark plugs

we just hit and knock them off the table

put some used spark plugs in it I had

only planned to go 4

seconds we're going to probably put

those back in just cuz we're going to go

a little further this time maybe the

full pull we'll see but the thing that I

think is most telling about that

run couple things so yellow drive shaft

red

RPM green is Boost blue is G meter so

the dotted lines are all

from uh the 745 at 193 pass at

Indie and with the stator change the

engine the transmission fluid change all

the little changes we've made the

car really responded

early so you can see boost wise we're up

1.9 there

G meter is

up

2/10 drive shaft is up through here 4

mil an hour 4 mil an

hour 4 miles an

hour

and do I have Target Dome on here yes so

you can

see Target Dome here comes up plateaus

at 30 so that's all we had 30 versus

49 we get out here to where the gear

change happens and the Boost shuts

off and basically the

car at the gear change is only 1 mph

slower and it

has 11 PSI less boost in

it

so that's

Rowdy I think it'll basically run faster

than 7

50 with somewhere around 30 lbs of boost

for the entire run where it took

Actually I don't even think it's going

to take that much um but I guess we'll

find out this next run cuz I'm going to

turn the instead of plateauing at 32 and

shutting off at 4 seconds we are going

to Plateau this is 30 we're going to

Plateau at 32 and run it out all the way

to the

Finish unless it sounds like it's

turning a whole boatload RPM and I may

clip her off early because we don't need

to go faster than

seven 50 and the air is going to be even

better tomorrow so we're kind of

planning all this stuff and trying to

figure out what we want to

do but if we can get one good full pull

on this next one that was a 12760 ft not

even

trying which a 127 60 fot I would hope

we could do anywhere so this Texas Speed

388 appears to be quite the

Beast I'm excited

like yeah let's go do it

again all right let's see if the camera

lasts I had a rear drive shaft failure

in the right lane we've been sitting

here for a few

[Music]

minutes and day so if you want to come

and out check out all

the

the gas on

apprach

[Music]

yeah

baby that was a good run hopefully you

guys like the parachute

shot all right that run felt pretty

sporty four PSI of coolant pressure 157°

water temp oil pressure is great water

temp's great battery voltage is good she

still

charging that felt like a pretty good

run for how low a boost I think it was

like I think that was only 27 28 lbs of

boost something like that so uh I guess

we'll see you roll the window down and

get my time

slipped thank you

o 755 at

185 that

works that's perfect cuz I think the air

is going to be a little better tomorrow

that might just be perfect now to get

back to the trailer and see what kind of

boost it took to do

that all right well here's our datal log

I told you I was hoping that run was

going to be less than 30 lbs of boost to

run 7

uh in the 755 that it ran and uh you can

see the number right there maybe what's

the number 25 1/2 to 26 1/2 no way there

is no way look at the data

bro so it's a little wavy so maybe we

got some some tuning to do there but

that bump right there is

27.3 wow the SAG there is

[Music]

257 I mean it's between the the conver

26 like it's a little it's so we need it

needs more power cuz it it falls 1200 on

the

shift what was it making at the shift 26

26 and A2 yeah right after the shift it

made

26 wow that's impressive this sucker is

a hot rod woo extremely impressive all

right well we're going to go get some

food finish loading this thing up and

I'm going to get to the hotel and edit

this video so that you guys can watch it

on Monday

morning we're excited we're having us a

good old time so uh yeah I just said

good old time I'm a southern guy it is

what it

is we're excited see you guys

[Music]

tomorrow

he
