Twin-engine Pontiac Grand Prix Update

Turbo Dynamics Twin-engine race car

The guys at Turbo Dynamics continue to work on their twin-engine race car. We have covered this project before when it was still resembled a Pontiac Grand Prix and when the group decided to build it into a race car. Most of the work focuses on getting the power to the ground. The boost is set to come on slower and the builder estimates 60% of the front engine and 70% in the rear engine’s total power is reaching the ground.

The with some tweaking and raising the boost they went back out and 8.42 second quarter-mile pass. They also hit the speed limiter at the end of the run which is keeping the time down as well.

After changing the wheel pattern to accept larger race slicks they are hoping for a 7 second quarter-mile pass at around 175 mph. With 1,300 horsepower the race car is estimated to be reaching 0-60 mph in under 2 seconds.

Pure Automotive Scion FR-S With A 2JZ

Although Pure Automotive in Millersville, Maryland services anything with four wheels their specialty is working on FR-S/BRZs. They have built over 40 forced induction FRS/BRZ projects. They also perform engine swaps on them as well. Their own shop car, a Scion FR-S has had a built FA20 motor with 477 horsepower, a LS2 V8 with 555 horsepower, and finally a Toyota 2JZ.

The engine was installed using Xcessive Manufacturing’s FT86 to JZ motor mount kit. Boosting the engine’s power is a 67 mm Borg Warner S400SX turbocharger. No word on how much power the engine is producing but the fuel system was built to handle 2,000 horsepower. The rear end is a Ford 8.8″ with a Eaton Locker LSD.

All this work was to develop an engine swap kit. Their goal was to prove the 2JZ could fit in the FT86 engine bay without hacking your car up. Whenever the kit is released it will allow you to install a 2JZ without cutting any core supports.

Roadkill Races The Draguar

Randy Pobst races the Draguar Roadkill Episode 41

The Roadkill guys decided to pull two of their favorite projects out of the garage for a shootout with Motor Trend’s top test driver Randy Pobst. The first car they choose was the Draguar, a 1973 Jaguar XJ12 powered by a 383 ci SBC and Weiand 6-71 supercharger. The second car was the Rotsun, a 1971 Datsun 240Z powered by a 4.3 L Chevy V6 with a turbo from a Ford Powerstroke diesel engine. But like many episodes of Roadkill things don’t always go as planned.

Bonus: The guys visit a private lot where they keep their previous projects and a stock car that has never been on an episode in storage.

Tony’z Garage in Victoria, Australia specializes in turbocharging Holden V6 and V8 engines. Their experience is on display with this 1959 Austin Lancer. The car runs a Series I Buick V6 with stock internals from a Holden Commodore and uses a twin-compound turbo system. That’s four turbochargers in total, with the smaller turbos run at about 8-10 psi and the larger turbos runs at 14 psi for a total of about 23-24 psi total of boost. The engine produces 402 horsepower (300 kw) which doesn’t sound like a lot running four turbos but then again engine is completely stock.
