Cartuning Performance Grand Prix GTP Turbo runs 10.93 @ 127.55 mph
10.9 run in full street weight (minus mufflers). Would have been a quicker run if 3rd gear would have held (you can hear it switching between 2nd and 3rd...I also let off the gas at the 1/8th mile to try and make it shift, and it ended up going into 4th for the rest of the run!)
TD Ben's Twin Engine Grand Prix GTP built by Turbo Dynamics
Currently only running 60% power to test the platform. Rear engine is stock GTP 3.8 engine, converted with a TD turbo kit. Running low Boost making 450HP for testing. Front engine is Supercharged stock 3.8 with a bolt on parts to make 350 HP. Results is spinning all four sticky tires. Test is done on a dust covered road on cold tires. Amazing that it is that quick in such conditions. That's the beauty of AWD ! 0-60mph in 2.6 seconds GPS 60 foot E.T. 1.53 seconds According to data this will be a low 10 second car in these conditions. And remember it's only running 60% power. At the track it will hook much harder and 60 foot time will be much lower !
