**v8klla** · 07-23-2007

It is Raptor's old car, but with Kyle in it it still weighs 2940 lbs per the track scale yesterday.

Yes we are using the PT71GTQ turbo and a 75 shot of nitrous. The downside is we were making boost adjustments throughout the day so we don't really know how much boost we were running, somewhere over 40 psi. We also don't currently have a means to log A/F besides the dyno and we didn't tune the nitrous on the dyno in fear of blowing the motor up lol. All we know if that when the nitrous was on we retarded timing 3 degrees and A/F went way rich just to be on the safe side.

The car has a lot more in it, we just need some more time and some reliable axles!
