7200? 7500rpm?

 

somewhere in the the 7200-7400 range from what I have heard theres a thread about this somewhere on here and someone posted the specs on the Lsj valves.

 

mine starts miss firing at around 7100.

 

well...a non-*** shouldnt need to go that high...ricer bitch...JK JK dont hurt me it was a joke...

 

Only reason i ask because hp would continue to climb if we were able to rev to 7500rpm. Thanks guys

 

I've have my rev limiter set to 7100RPM. I shift about 3 seconds after my shift light on my interceptor lights up at 6800RPM. 7,000 should be plenty. You do notice a difference in power with it higher but I cannot imagine it's worth the explosion your going to create making it go that high.

 

are you sure thats not your rev limiter LOL

 

The highest I have seen it run consistantly is 7400..... I think the valves float at that rpm though. I ran mine at 7200 alot of times with no issues.

 

I have my limiter set at 7400, I've come close a few times without any issue.
When I had the stage 3 pcm in, I set it to 7600 and it worked just fine.

 

Damn 7600! Thats huge haha.....

 

Thats what she said!

 

I don't set it to hit it, I set it high so I don't. Make sense..?

 

Has anyone ever dyno'd to 7500rpm? I know the powerband keeps pulling to 7000rpm so 500 more would probably yield a few more ponies.

 

nobody should go over 7200 , but with valve springs you can go 7500...

lol ; Imagine if you didn't know what a rev limiter was and you hit it for your first time. You would say to yourself, "Awww ****". lol

 

Ya it makes sense. I dont know if your tach blows as much as mine does. I have my rev limiter set to 7200 and on the tach it reads 7k-7100 rpm's when it will hit the rev limiter.

 

i think the gauge is a little slow mine does that too i just shift a split second before i hit 7rpm

 

Another reason I set it higher. The time period between actual engine rpm and vcm recognition are off sometimes so its better to play it safe.

If anyone decides to run the engine above 7k constantly, I'd strongly suggest changing the valve springs to begin with, but doing it occasionally shouldn't hurt anything.

 

no doc set my fuel cut at 7200, funny thing is i still seem to hit the rev limiter guess i need driver mod stage 5 now.

 

I only hit the limiter once. Of course it was when I was getting on it hard in 1st.
*punch gas* ROOOMMM-put-put-put "What the hell? That was quick!"

 

I like the limiter. Sounds cool, and makes the car throw flames. Not good for racing though, but fun when driving around on wet roads like tonight. Waaaaaaa-BAP-BAP *shift* Waaaaaaaaaa BAP-BAP-BAP
