turbo civic putting in work

That would be correct, but at the same time there was something else holding me back from making more power past 8000rpms. the culprit has been found

still i wouldnt rev a 2.4l with a 99mm stroke much past 8000 or youre going to be rebuilding the motor quite often. Unless you dry sump it. (unless they have fixed something with the K motors and their oiling problems).

And its pretty evident based on your graph that you arent going to make much power past 8000 no matter what you do. you make peak power around 7500-7600 (unless my eyes are bad). Extending that power PAST 8000 is going to be hard and if you do it prob wont be significant. I bet youll end up making MORE POWER but prob around the same RPM. May peak around 8000 but even then , its not your whp thats dropping off a cliff its your TQ. It falls almost 50 ftlbs from 7000-8500. Your hp kinda plateaus meaning either you are holding it back (restriction somewhere) or thats all its gonna make.

I think you would be better served shifting earlier and getting a 5.0+ final drive. But you wanna run nitrous too so you dont wanna have it too short geared.

more power on the existing gearing wont necessarily make it much faster.

IMO of course

Its called using a a2 pump or moddified s2000 pump and 99+mm strokes can go 9-10000 all day! depending which pump u use

Well whats on the graph is all i'm ever gonna make

I always HEARD the oiling problems were never solved even with the A2 or S2000 pumps. It wasnt a pressure problem it was a lubrication problem. But i think that was more on the road race engines than the drag or street car stuff. Road race is much more harsh.

I dunno i would just be weary of 9000-10000 rpm 99mm strokes, thats a lot of piston speed and stress lol

Good luck though im sure youll let us know how it turns out :P
