Personally I have seen why a .86 over a .64.....

For my setup a stock intake and exhaust manifolds, and 264 step 1 cams, to have 320HP and 270ft.lbs of torque at 16.5 psi on a dyno dynamics... I highly doubt a .64 can reach it with the same setup. Yes bla bla bla do this and that and boost up on the .64 and yeah it can do it.... But that is apples to oranges....

You have to create the same scenario with two different turbo's on the same boost level, otherwise like I said its apples to oranges. At 4800RPM I made Peak Torque and 5200 Made peak HP.... Like I said I doubt a .64 will do that on the same setup....

Keep in mind I track this car and is conservatively tuned by steve shadows.....

Whatever that maybe, you can't start changing a billion things and just compare the turbos, that just isn't good statistics.
