Ex-Grandpa's Car Transformed into BIG HORSPOWER V8 Turbo Monster!!

Summary

The video follows Tony Angelo and his team as they attempt to build a high-horsepower sleeper car using a 1998 Lincoln Mark VIII. After previous engine failures, they install a rebuilt 4.6L Ford V8 and large turbocharger to achieve their goal. During dyno testing, the Lincoln produces nearly 520 horsepower thanks to the upgrades, despite some limitations. The impressive results restore Tony's enthusiasm for the project, leaving him excited to further modify the unassuming sedan and reveal its hidden performance on the street.

Takeaways

• 😀 They are rebuilding a 1998 Lincoln Mark VIII sleeper car with a turbocharged Ford 4.6L V8 engine
• 👨‍🔧 The previous built engines failed due to low oil pressure and blown internals
• 🛠️ They installed a used short block and new turbocharger hoping to make over 500 hp
• 🔧 They primed the oil system properly before startup to ensure oil pressure
• 🏎️ The car made good oil pressure on startup around 90 psi
• ⛽️ After tuning on the dyno the car made 499 hp and 507 ft-lbs torque
• 🔥 With more timing and boost it then made 515 hp and 520 torque
• 😥 They maxed out the 160 lb/hr fuel injectors at 87% duty cycle
• 👍 The turbo Lincoln sleeper was a success making over 500 hp finally
• 😀 They can't wait to drive it on the street and test the new found power

Q & A

What kind of car are they modifying in the video?

They are modifying a 1998 Lincoln Mark VIII luxury coupe.

What is the goal of the modifications they are making?

The goal is to turn the Lincoln into a high-powered sleeper car that can make a lot of horsepower but still looks stock and unsuspecting from the outside.

What engine are they putting in the Lincoln?

They are installing a built 4.6L 32-valve Ford V8 engine with a forged bottom end, stroker crankshaft, and upgraded camshafts.

How much horsepower were they able to get out of the engine on the dyno?

In the end, they managed to get 515 horsepower and 520 lb-ft torque at the wheels, which translates to over 600 horsepower at the crankshaft.

What upgrades did they make to the turbocharger system?

They upgraded to a larger Turbonetics 7275 turbocharger and dialed in the electronic boost control system for better response and power delivery.

What fuel system upgrades will be needed next?

They maxed out the 160 lb/hr fuel injectors, so higher capacity injectors will be needed to supply more fuel for additional power gains.

What drivetrain components did they upgrade?

They installed a built 4R70W automatic transmission and upgraded the driveshaft.

How much oil pressure were they able to achieve?

The oiling system modifications and pump priming procedure allowed them to achieve 90 psi of oil pressure, much better than before.

What was one key reason for failure previously?

Not properly pre-lubricating the engine and priming the oil pump before initial startup led to oil starvation and engine failure.

What types of racing might this car now be competitive in?

With over 600 horsepower at the crank, this car should be highly competitive at the drag strip and well suited for street racing.
