Sometimes, when I am "getting on it" in my car I will shift to late and hit rite at or a lil. above 6000 grand and the car bogs out, is that hitting teh rev limiter? Is it real bad for it? I kno its not good for it, but What could it mess up?

 

You could potentially screw it up, it's not good for it to hit the limiter often...It bogs because the injectors won't push the fuel through the car fast enough, possibly some other things, not real sure of major details.

 

first off, unless you have a hi perf setup, peak hp is 5,600rpms for the 3.8 but based on your name you have a LS1, which the rpm peak would be lower than the V6 b/c of displacement. Going up to 6K will get you less power than 5,600rpms so I wouldn't do it...and yes, if you do that regulary it can hurt your engine

 

The profile was made b4 I got my car, that Is what i planned on gettin. But I ended up withe the 96 3.8.

So 5600 is peak?

 

yep...200hp@5,600rpms, so anything past that the hp will decrease

 

Redlines are not 'absolute' in a street car but still shouldn't be exceeded. There's usually some safe cushion between the rev limit and actualfailure rpm.

Not all rev limiters work the same. Some retard the ignition timing, some reduce or cut out the fuel delivery while others shut off the ignition (less favoritable because of HC emission and possible CAT damage). I'm not sure which one GM uses. But someone here probably knows.

Will it hurt the engine to keep bouncing it off the rev limit? It's not the best for it, but more damage and wear will show up in your drive train, probably as rear U-joint failure, excessive lash in the rear end and trans as well as some loud noises from the wear.

Shifting a street car for max. acceleration is a bit different then shifting a car built for it. Thing to remember is torque does a lot of the work. You want to shift to leave your engine in a usuable part of your torque curve when the gear change is done. That's why purpose built cars have 6, 7 or even 8 foward gears (F-1) andbig trucks as many as 15 with their split trans and differentials. You'll probably find your best shift point somewhere between 5000 and 5600 rpm.

 

ite, im used to the car now so i got it pretty good now, thanks

 

that range will change as you mod the car as well...practice is the only way to find whats best for your car
