What is the best RPM to perform a hard launch in a stock 07 G35 Coupe 6MT?

 

Redline...

Since all motors are different, the best way to find out is to dyno your car

 

just practice.
get the feel for your car and adjust from there.

 

duh.

 

launch at 3K so u dont waste energy on a burn out

 

gosh, such abuse on the car. so many launches.

anyway, i don't think this really answers his question.

 

Too many factors to give a simple answer. Variables include mods to the car, tires & tire condition, weather, track prep, driver ability. Go to the track and start low and work your way up into different rpms for your launch. Every car and driver is different so best way to learn is just practice.

 

i have a non revup and you can tell by my sig my modest list of mods

and i launched at 2k today and got ****ty 60's

like 2.5 was my best.

 

Are you dumping or slipping the clutch at 2k?

What tires?

Track prep?

Are you bogging off the line or spinning?

 

You will find out by practice, depending on how quickly you release the clutch, that optimal RPM's to launch on stock tires/ stock power is anywhere from 2500-3500 RPM's.

 

i BELIEVE i have the stock potenzas

track wasn't great, dropping the clutch to warm up tires and i'd spin forever


but yea i'd be spinning. no bog.

i thought my best launch of the night was when i launched at 1500rpm and floored it barely no spin at all. and netted me a 2.509

 

You should be getting way better than a 2.5. No offense, but 2.5 is boo boo. I could out launch you in my wifes xB. LOL.

But seriously...

I have crappy Goodyear Eagle RS-A's on my OEM 19's and still manage a 2.1-2.3 on a track with almost no track prep.

You have to work the clutch and the accelerator. When you do a good launch, you feel it. Trust me.

Slip it until you feel it hook.

Dumping the clutch on launch doesn't get far. Ease out of the hole.

Your best bet is practice on an empty road to get a feel of a good launch.

 

first time at the track. i know for sure 2.5's are bad. i think it's killing my 1/4 mile time


i'm going o try in parking lots. i keep dumping the clutch.

 

2.5? u could just roll off the line and beat a 2.5..and i thought the 2.3s in my rsx were horrid

start out at like 2k and work your way up

 

Do any of you lower your tire pressure at the strip?
