Redline on my 4-banger?

Hey guys,

I'm looking at doing this to my gauges, and thought it would be cool if I added a red-line to the tach. At any rate, I was wondering if y'all knew what the redline on my engine would be. 4-cylendar 2.3 SOHC, I think. I can get up to 70-80 around 3,000 RPMs but I personally don't push it faster then that. 3,000 sounds fairly high when not on the highway.

Anyways, I'm just curious and would appreciate it if someone would satisfy my curiosity.

Josh

Starting at 5000 or 5500 rpms is where i'd paint it red.

yea, the rev limiter from the factory is 6250RPM so just before that is a pretty good place to set the redline, say 6000?

There is no red line because there is a rev limiter. It won't let you get to dangerous rpm's hence no red line.

Old thread, but like stated above, the 2.3 hits the rev limiter at 6250 rpm. However the power curve drops off at about 5500 rpm, that would be about the ideal place to shift. After that rpm you're not really "pulling" anymore.

I usually shift when my rear view mirror starts vibrating so much I can't see out of it anymore. One time it actually fell off the windshield. I don't think I ever hit the rev limiter. I have hit the 100mph fuel cut though.

Thanks for the posts all. I've decided not to paint on the redline after all... since it would only show up at night.

Even the new 2.3 DOHC have a cut off of 92 or so mph, my 05 Ranger could never in its dreams make it to 100mph without a tuner.
