I've been looking at all the flow maps on this page but none of them seem to line up for very long if at all, in the highest efficiency circle.

Maybe I'm not doing it right. This is the information that the Turbo calculator is telling me.
20psi equals 2.36 atmospheres right?
If you guys have any suggestions they would be appreciated.
Thanks! |
Just remember that if you change the internals of the engine, pistons, lower compression pistons and you do a stroker kit or whatever. Your numbers will change and it might not take 8000rpms at 20psi. It's going to vary greatly on the power that your engine is putting out in addition to what boost/flow the turbo is giving you. So if you build a monster 420a then you are going to have waaay completely different numbers, And to make 500 horses you are definately going to have to make a monster 420a
