Okay, I have had the G37s for almost a week now and I have a few performance related questions. I just installed a Greddy ti-c cat back and I love the sound and performance difference! I am wondering if getting a chirp from the p275/30R20's is possible with the stock clutch? and if not which clutch would be a good streetable alternative to the stock unit? Also I was unaware that the rev limiter starts in at around 5K (well at least in neutral not moving) is there a way to ditch that? I am assuming some type of power programmer? Thanks in advance!

 

You're probably on the wrong forum, bro to be honest. People here don't really dog their cars out like that.
FYI: Pretty much any car can chirp the wheels if it is a stick. And once you put the car in gear, the redline that you see on the dash is true. Not sure why you haven't noticed that if you've driven it for a week.

Have you driven it?

 

I can get my 19's with 305s to chirp.

 

^hes right. If you clutch in while stopped or if your moving then redline is 7200ish. Other than that what wheels do you have? How heavy? Thatll make a huge difference as to how easy those tiresll break loose.

 

I think he means if he floors it in neutral at a standstill, it'll cap at 5000rpm.

I don't really know why you'd want to take that off lol, but I'm sure there are tunes that'll do whatever you want them to do to your ECU.

And by chirp, do you mean burnout, or 1-->2 chirp? If it's the shifting chirp, it all depends on how fast you shift and what RPM you shift at. Just practice your shift times and you'll get chirp into 4th lol, even with your 275's.

 

The redline is not at 5000. That's an idiot proof feature to keep stupid people from blowing up the engine by trying to redline it in neutral with no load on the engine. If you want to chirp the tires, disable VDC and rev it all the way to the idiot redline and dump the clutch suddenly. They'll chirp.

 

I hope this car isn't turning into the teenager's wet dream...

 

Too late.

 

I really had no idea we had a lower 5K redline in neutral, but would never do that to my G. I guess you learn something new everyday.

 

Please do not drive with the vdc off. You have a lot to learn about these cars and how to treat them.

 

But in all seriousness... you might not want to do that... hahah.DOMO

 

^this threads just getting better haha. Op just work on your shifting poe they said and be careful. I never have vdc on it just slows you down on the twisties and for quick shifts. You better know what your doing though if you leave It off.

 

It's more of a soft rev limiter than a redline, but yeah. Most modern cars have them, even automatics.
