Dude, if you have a 2007-2008 350z you have a 7500 rpm rev limit, not 7800. It is hardly safe at this RPM.

What kinda times you running?

 

last time i went to the track was when i first got this car and i got a 13.739 @ 102 thats just cuz i couldnt launch worth **** but ive been practicing on that. dont no exact id have to find my slip

 

 

LOL u guys crack me upi love 350z forum

 

So you want more RPM to be faster...I'm .5 seconds faster with a stock car...I don't think the rev limiter is causing the slow times.

 

i no its cause i cant launch rwd cars cuz i suck.. i can only launch my r32 (vw awd) and thats it lol IM PRACTICING IM PRACTICING!

 

I'd say, do lots of reading. I've posted my technique a few times, Veetec has posted his, and ranger (corvette guy) has a site dedicated to it. In one day advising a friend I got him from a 13.8 to a 13.3...took like 3 runs knowing what to do and he had the launch down.

 

13.73X
13.7XX
13.XXX
1X.XXX

How much are you guessing?

in order to use that high rpms, you will need to raise your compression and internals and intake manifold, other than that, there is no power in that rpm range.

 

How is 8,500 RPM working out?

 

Outstanding!

 

as i read this i cant help but think... i used to run these tracks in high school from here to the train tracks is a quarter mile.. on green im goin... fu&*&*n newbs.. i been shiftn at 8000 an i feel like straight s*** moved up the rev limit with the cobb... and why would you want to do that to such a perfectly built engine... go to rice if you wanna shift at 9000

 

This thread is full of lol's

 

I thought I was crazy for wanting to take my built DE to 7500. Wonder if the OP went through with it? Or better yet if it still runs... NOS and raised rev limiter on a stock bottom end.
