I'm looking for some information (namely, track slips and dyno charts) for cars that have already been modified for performance. I'm looking for seperate information for TT, Supercharged, and N/A built engines so I can decide which route I eventually want to go. I am planning on doing the mods in the G50, so info from that chassis and not a swap would be best. Thanks in advance for any information.

Since there are only a couple turbo'd G50's around, including mine, and none with SC that are documented you are likely to only get NA numbers from the G50 crew or take turbo numbers from the swap guys.

I had some issues when I did my baseline dyno prior to the turbo and only managed 222 whp. Average in stock condition NA is about 240-250 hp at the wheels. I'm shooting for 400-450 whp when my tuning is done. I'm working on tuning for 8 PSI currently. Hopefully I'll get my next dyno done within the next couple months.

I don't have any timeslips but I would guess that my car can run a high 12 sec quarter mile after the turbo install. This is on a 94 Q45 with a stock VH45 and 6 psi from a Garrett T76. I'm also running a 4.08 diff, Level Ten transmission and a Carbon Fiber Driveshaft from ACPT.
