Yea, his car is slow down low...lack of torque..we were trying to figure that out last time I was with him tuning, but never really diagnosed the issue..hopefully that test pipe will help!

Hey guys I thought I would chime in.



We aren't testing different spots in the intake. Just testing the stock intake close to the end of the big hose. We are going to do it again with the K&N drop in and the Cold Air Intake that I make. I already know that my CAI does lower temps a lot and the butt dyno says its good. Real dyno tests are also in the works. We will be using a similar spot on the CAI to test for vac on it but still after the AFM and before the TB. We are going to do tests with a new MAzda OE filter. The powers that be at rx7club don't think that Fram is good enought https://www.nopistons.com/forums/pub...1047683664.gif

PS- tests to come! https://www.nopistons.com/forums/pub...1047683473.gif



And I am going to be working with James' car and my own S5 TII shortly to come and the final version will be made public some time next year.

fram is prolly not good enough.

for those of you that want to convert inches of water into psi you do this



inches of water x .03613=psi



so the gauge pictured is a 0-1.8psi gauge
