Really happy with the powerband. Cams will make a bunch more power but it proves my opinion/experience that a big turbo moves the powerband to the right. More power at 6200 rpms than 4500. That means even at 6200 rpms the motor drops out of peak power by a LOT.. 3.50 final drive a543, 240hp at 6200 rpms and when shifting to 2nd gear you drop to 3900 rpms and only 195whp. Crazy! Mindblowing! The stock rev limiter is holding back turbo 3.0s even on stock cams! 2nd to 3rd gear drops from 240whp @ 6200 rpms to 225hp @ 4300 rpms!!!!
Pushed coolant on the 3rd 13ish psi run so we (with Reaper1) backed it back down to 10psi. It was probably starting to knock at 12psi.
Stock 3.0 motor, 92 octane. Stock n/a timing map. With timing control there is probably a lot more room to go and the same with alky injection on stock timing. Probably more to gain with modified timing maps.
We were at my Union's yearly car show and they had a mobile dyno at the event. Only out torqued by a Corvette and only by 9 ft/lb :P The supercharged alcohol dragster that tried to make a pull came in last place lol.
