Hey i was wondering if anyone is using the Precision PT-67 and if so what is the spool time like? If anyone has dynos that would be awsome too. Im also wondering the samething with the GT35R. I saw the HPF GT35R turbo kit and it looks like it starts spooling hard at 5200 RPMs. Also on either of those turbos if i were to increase displacement by 10% how much sooner would it spool? any would be great.

 

the 35R really hits around 5000-5400 rpm in 3rd and 4th gears. the pt6776 P trim will be a few hundred rpm later but nothing too crazy. prob 5200-5700. but even so if your running 30+ psi, your making enough power by the high 4000's that it wont be too bad. and spoolup rpm changes with each gear, dont forget that
