Bumping Up The Rev Limiter?
Hey guys, how would I go about raising the rev limiter up to 7k RPM?
I have an '01 Cavalier with a 2.2. I know these are pretty durable engines, so what precautions would I need to take before bumping the rev limiter up (if any)? I'm replacing the head gasket once I get paid because it's starting to leak. Is there any benefit to doing this, or does the power/torque curve die past the 6.4k point? Thanks for the help. |

You can't...the rev limiter is built into the programming of the
PCM.... |

Mine has the Ecotec, so this may not be extremely relevant... I have mine set at 7,200 RPM, but the power does drop off noticeably at about 7,000 RPM. I left the extra in there just so I don't have to worry about bouncing off the rev limiter. It's nice to be able to go a bit higher, but not worth paying for, IMO. It's also worth noting that mine is supercharged, so it's possible that yours may have some added ram-air effect since you have intake runners and I don't. It's also possible it may starve for air.

On that engine, kiss your head good bye without head work, stronger valves and stiffer springs, roller rockers...
