We just finished tuning a 997.1TT with Ivan over at IMA Motorsports in Va. Prior to hitting the dyno, we had calculated out the crank hp using datalogs at 1055 hp @ 6927 rpms and 1021 ftlbs torque at 4611 rpm. The final dynos on a 4WD linked dynojet were 910whp / 960ftlbs at the tires. So, approx. 15% power difference and 6% torque difference, averaging 10.5% loss to the tires which is totally expected. This is a 3.8 built lower end, otherwise stock with older alpha3076s or XR960s on it. You can see they're totally maxed out since it's making nearly the same power from 5500->redline. It's running E85 with our triple pump system, intercoolers and fenderwell intakes. The exhaust is a bit restricted with a merging style xpipe. so there's still room for more improvement. Next time around, turbos, our xpipe, gt3 intake, cams and ports. Here's the calc'd dyno and 4wd dynojet results from this morning.
