how long will a 3.4l v6 in my camaro take 7000rpms didnt mean to do it to day but it dont seem hurt or un happy its like the motor try's to get there and pulls harder the higher the rpms

 

Your rods are forged and rated for 7000 RPM by GM, they are the same rods as in the 3.4 DOHC and those guys spin past that but not much.


I'd worry more about oil pump cavitation, water pump cavitation, oil starvation, detonation, broken valve springs, collapsed lifters, wiped cam lobes etc.. then the rods

 

I would blow it to 9 grand on purpose just to get a better engine, if that helps.

 

Don't go past 5500 on a stock motor, for one thing there is no reason to, for another you will encounter valve float any higher.

 

Im not sure why'd you want to go up to 7k rpms, on a basically stock valvetrain, and those iron heads are crap in high RPM's unless you apply boost or n2o, then those heads really dont matter "as much"...

Sure that your tach isnt off?? Mine says its shifing at 6500Rpm but in all reality it shifts about 1k less then that. Datalogging proves that. But i knew a long time ago it doesnt shift that high...

 

theres no way his stock motor is pulling to 7k maybe in 1st gear were there is the least load on the motor.

and without oil pump and oil system mods even if it does rev that high it will only do it a few times

i had to do alot to make my motor reliable to 7,500 + rpms

cam
valve springs
modded lifters
shimmed presure valve in the oil pump along with some maching of the pump itself
ive logged a max of 8,800 rpms which was an accident during a burnout needless to say it wiped out my valve springs

normally ill spin it to around 7,600 max

 

ok let me be more clear i don't mean to turn it passed 6500rpm sometime;s i rev it and it shoots to 7000+rpm tach stops at 7 and i dont holed it there i let of as fast as i can lol nope got cam and springs in it want to do 1.6 roller rockers pulles tune hears and a roosts blower or just swap in a lt1 v8 kinda hate to give up on the 6 its a fun motor and been on here for 5 ish years

 

hu?? Sorry man, you lost me in this thread

If you got the mods in it you say, then dont give up on the V6.. there fun little motors to work on. I love all the room in the engine bay!!

 

im trying to keep with ls1 crs and it kinda makes me want to swap in a lt1 but i want to do the v6 cuse its light and like you sed lots of room

 

Add this!!!

 

ok thanks alot

 

no rev limmiter in the 92 camaros ?

 

My 91 stock V6 cutout, as of the original Bin file, is 6085Rpms i think.. something like that

 

maybe i should add one

 

The only way you dont have one is if youve tuned your stock eprom(ECU)

 

its got a 89 2.8 corsica ecu was thinking about swaping to a feiro gt ecu

 

Why?

 

6212 RPM and a 112 MPH cutoff in the early gen 2 tunes.

 

ok you lost me

 

My cut off "was" 115mph fuel cut off and 6212Rpm fuel cut off, on a 1991 3.1L 7730 ecu

 

The rev limiter set in the gen 2 tunes is 6212 RPM and the speed limiter is 112MPH. 89 Corsica 2.8 is a gen 2 engine, unless you put the stock memcal from your car in the 1227730 ECM in which there is no difference, rev limiter is still around 6200 RPM.


you won't be able to rev the engine past that unless it's mechanical like you drop the car in 1st at 60 MPH

 

I wana see someone do that but not in a thirdgen..mabey a stang though.i love thirdgens too much wana see that happen

 

so maybe my tech is way way off bc i have never found a fuel cute or speed limiter

 

Most likely the tach is off, and the biggest concern would be valvetrain, here and there by mistake isn't likely going to hurt anything, but I certainly wouldn't drive around winding it out to 7k all the time, eventually your valvetrain would give up. Not to mention splitting the lifter valley would be a possibility, though that would require a lot of abuse.

 

lol ill miss that when i do my lt1 swap for sure i always wanted to boost the v6 but for what i want and want to run i cant see it being fezable and lasting
