Safe RPMS for a SR20VE + N1 cams
Guys,
A friend of mine is building a SR20VE with N1 cams, big header, big muffler, big intake manifold w/ Q45 TB and we need to know what would be the max RPMS we can rev the engine safely. I mean how high can we rev if we are still making power. The issue is that we have read that the 4cw crank is not a good example of a balanced crank so he is worried about any engine failures for revving too high.

He is using also aftermarket springs for the head so from that side we are not so worried.

Any help?

Thanks guys!

Stock redline on the sr20ve is 7200, you can not rev higher.

We have a Nistune ECU and N1 cams, and bolt ons that would let the engine breath at high rpm...

My vote is to revS it till an intake valve makes it out the exhaust.

Also not sure why cory is concerned about VE recliners... But I applaud the idea.
