Heza Posted July 4, 2003 Report Share Posted July 4, 2003 so...i passed up my friends in their BMW 318 and my intake was roaring. we got to the pool and parked and they said my 3100 sounds pretty throaty with the intake. very happy expression at that point. so we swim a little bit and then i get back into my car, start it up, and for shits-n-giggles i rev it...BUT...it hits the usual 4k or so limit and then keeps reving up to 5800 RPMs! tried to do it again after i drove it a little bit, but was limited again. anyone got an explanation on that???

Baddflash Posted July 4, 2003 Report Share Posted July 4, 2003 Seeing as your HP peak is at 5200 rpm I doubt your RL would be 4k, it should be around 6K. Quote Link to comment Share on other sites More sharing options...
kfahn Posted July 4, 2003 Report Share Posted July 4, 2003 when the car is in park or neutral, there is a rev limiter around 3500 to 4000 rpm's so as not to damage the engine, (Over-revving it), but no i have ne explanation of it! Quote Link to comment Share on other sites More sharing options...
Baddflash Posted July 4, 2003 Report Share Posted July 4, 2003 Strange I hadn't noticed that the RL changed depending on if in gear or not, but I've got Gen2 3.1L not Gen3 maybe different. Still I don't see the RL changing or being set so low?????? Quote Link to comment Share on other sites More sharing options...
Heza Posted July 4, 2003 Author Report Share Posted July 4, 2003 Seeing as your HP peak is at 5200 rpm I doubt your RL would be 4k, it should be around 6K. all gen 3 3100s ive seen have a rev limiter at 4000. but, for some odd reason, i could rev my motor past that that one period of time. i'm baffled.

Vegeta Posted July 4, 2003 Report Share Posted July 4, 2003 There is a P/N limiter and an in gear limiter. Maybe your car didnt see the P/N switch activated that one time? Quote Link to comment Share on other sites More sharing options...

OldsmoBeast Posted July 4, 2003 Report Share Posted July 4, 2003 were you rolling? because if i'm above a certain (Low) speed in the cut, I can rev well past the P/N rev limiter. EDIT: in neutral Quote Link to comment Share on other sites More sharing options...

phantomFE3 Posted July 5, 2003 Report Share Posted July 5, 2003 when i first got my car, in the cold winter i could revv it up to like 6g's, but now in the summer it only gos up to around 4 or so (revving it in neutral, standing still) when it gets to 4gs or so its like a "chugging" of the engine, is that the rev limiter?

god910 Posted July 5, 2003 Report Share Posted July 5, 2003 its like a "chugging" of the engine, is that the rev limiter? Oh yeah, it's good times, sometime when you are in Park just floor it and keep it floored, it will do that all day. Weeeeeeee. Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted July 5, 2003 Report Share Posted July 5, 2003 Oh yeah, it's good times, sometime when you are in Park just floor it and keep it floored, it will do that all day. Weeeeeeee. I wouldn't do it all day. Just doesn't sound healthy, ya' know? Rumor has it you can (over time) ruin the engine since the ECM quits fuel delivery to the comubustion chamber? Maybe I'm wrong, and if so, would like to know how the car reacts to a RPM maximum command. - Erik Quote Link to comment Share on other sites More sharing options...
phantomFE3 Posted July 5, 2003 Report Share Posted July 5, 2003 ive only done it once or twice, i thought it was something bad with my engine because when i first got it it didnt do that at all, but i guess its supposed to be there. whew!

hazmatic Posted July 5, 2003 Report Share Posted July 5, 2003 revin the engine while not in drive can flood the engine am i correct? Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted July 5, 2003 Report Share Posted July 5, 2003 revin the engine while not in drive can flood the engine am i correct? If the engine is running you can't flood the engine during normal operations. Same with a EFI vehicle in the off position; mash the gas, the car will not flood. However, a carbuator will flood the engine, so don't hold the gas down while off on your Trans Am. - Erik Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted July 5, 2003 Report Share Posted July 5, 2003 There is a P/N limiter and an in gear limiter. Maybe your car didnt see the P/N switch activated that one time? from what i can tell with my car, it DOES have a speed limiter (116 MPH), but DOESN'T have a rev limiter. i just did 61 MPH in 2nd gear the other night and the RPM's were redlined at 6 grand. i don't plan on doing that again with the current engine but it sure sounded great! fwiw, i think my car doesn't have a rev limiter sinced it's a manual. i'm running '90 GP wiring harness w/ECM & calibration. does that sound right Vegeta? joshua Quote Link to comment Share on other sites More sharing options...
