or did you gain anything at all since stock at 6800 rpms you have 166hp then of the REVI intakes you have 167hp and 175hp... so which one is right? Did it gain 1 hp at this rpm or 10 hp?
looks like a bunch of variability in the dyno

what kind of flywheel you have.

Well the 3rd Gear Run with the Intake proved to be alot lower in HP then the 5th Gear run with it. There were also some funky AFR at the begining of the 3rd gear pull with the intake on that I can't explain
But far as if i really made 20 or 15 or 10 at that specific RPM is irrelavant, i was just happy to see that the flywheel, clutch/pp combo was doing what it should, loosing small amount of torque and HP in the lower gears then gaining 10hp in the midrange and extending it to the peek with mild gains.
I only said 20 because if you look at them separatly not for their "real" numbers they both gained 10 on their respective runs.
Did vouche however that the REVi did make 10hp in that midrange since the dyno was done withing the same hours almost and the position on the rollers never changed.
It probably would have made a nicer "peek" number if I didn't listen to danorobe and used a lower gear as all that spikeness is a result of the high wheel speed.

I think I misread what you said. Were you referring to 10 hp from the intake and also 10 hp more at the wheels from the flywheel? I'd believe this. I thought you were saying that the intake got 10 hp on the wheel dyno so it must be 10 more than that at the engine due to drivetrain losses and therefore a total of 20 hp. It definitely doesn't work like that.

The Intake made 10hp in the midrange vs. the stock run.
The Flywheel Clutch PP combo made 10hp vs. the RB intake run in 3rd gear.
However the "number" of the Flywheel Clutch and PP run wasn't much higher then the REVI intake number at that same RPM, but thats irrelevant because it was a different gear.
