revlimiter

[russianpimp15]

hey does anyone actually know how to remove the revlimiter and what controls ur revlimiter in the first place ? my old 240 redlined at 8000 rpms and my new one red lines at 7200 which i dont understand y

[93HATCH240]

Unless you have head work done i wouldnt bring it past 7200. And nowhere near 8000. The most ive ever shifted my old ka at was 7400 and that was pushing it. Started smoking like a bitoch and burning oil.

If you can show me power way up there on a KA with out putting like 4 grand into it Il tell you the secret.

But I don't think there is a KA out there that makes any useful power past 7k.

[nissanfanatic]

Yea there is.

Search for Miami240's car on ka-t.org. The dyno sheets from his car are on stock cams. His setup now sports Crower V3s. It makes good power well past 7k.

My car peaks out around 6700 and that will probably change when I can tune the timing curve better.

[S13FX]

Well then in that case Il shut the fwak up heh, From what I have learned with my KA, is that it's harder then usual to get any power above 6500 cause of the longer stroke, But hey I guess if you say you've done it then you've done it right.

Those characteristics aren't really what determines the powerband. The harmonics, dictated by the design of each component, of your intake/exhaust manifold and head ports are really what decides where your car wants to make power. Camshafts profiles support the respiration of the engine at that power level.

well to the OP, unless both your ecu's were reflashed, i dont see how they would be reving that high. stock redline is 6500...at least on my s14 it was. were these stock cars?

I'd want valvesprings over 7500...

[nissanfanatic]

Yea. I didn't include it because it has no effect on when the engine makes power. They will just keep the engine from destroying itself when attempted.
