Launching Question?

[AcCoRdKiD916]

I have a f22 with an AEM cold air intake.. my question is what's a good rpm for launching..right now I launch at 5000 rpm..

[Mayhem Tripp Robinson]

for what kind of racing, what kind of tires u useing and is it a stock cluch

[Mayhem Tripp Robinson]

i thnk 5 is to high u get to much wheel spin,

Sounds kinda high.

1. Every car and person is different.
2. Every car acts differently.
3. DO NOT DUMP the clutch.
4. Tires and suspension play a big role on how high you can launch.
5. 5k is pointless for your car unless you have some sort of grippy tire.

i wonder what tire pressure he uses to prevent tire spin at a 5000 rpm launch.

probably rock crawling tire pressures

[AcCoRdKiD916]

I use slicks and I have a stock clutch and its lowered 2 inches and the tire pressure I'm not 2 sure my brother handles that and most of my adjustment.. he think launching at 5000k is perfect..I don't think so.

[Mayhem Tripp Robinson]

on what kind of susption, and i would say u should also look in to a stronger cluch, and is it sping of the line,

[Flatline]

5k sounds pretty high to me. Especially on a stock clutch. When i ran my H i was launching at around 3k and still spun tires(no slicks though) and my stock clutch would slip in second gear.

but i am new at the strip.

I launch at 4k-4500 with street tire. It hooks up pretty good. With the F22A6 I did close to 4k launches but I had some good tires to go with it.

if you can maintain traction then launching high is good. if you spin drop it down more.

the suspension is more than just how low you are. i have adjustable shocks on my car and it made a huge difference when i played with teh settings to launch.


generally the highest rpm you can do while maintaining traction is best. if you dont spin at 5k, launch at 5k. it will beat on your clutch and axles though. slicks especially put a load on the axles, and the transmission itself.

try this. jog backwards. then without stopping, break into a forward spring. thats a very small representation of what everything from your tires through your engine is going through on a hard launch

I get tire spin but not that much

launch it at 7k haha. na i launch at 4k and get bad tire spin but thats cuz i dump the clutch lol. i have no idea wat a good launch would be...maybe in the low 4's

you preload the drivetrain. dumping the clutch breaks parts.

I would say 3500 to 4000. I wouldn't launch any higher than that because you just get wheels spin. I get well spin sometimes just normally, just mess around with different lanuch rpms at the track and see which one produces a faster 60ft time.
