Launching

[hondakid1996]

Hey everyone. I was just curious what rpm you guys launch at. I mean at the drag strip or any type of race. Im rockin a pretty stock f22a1 with I/H/E so im not making but 100 whp if im lucky lol. Also, i have a factory clutch and all other drive line components. The reason im asking is because i would like to get good launches without breaking something and spinning too much. Thanks!

125 hp.

125 hp.

at the crank..

op 1800-2500

I wish i had 125 whp lol. Anyway I generally launch right around 2k anyway so cool. Thanks.

Are you still learning how to drive?

It's 125 BHP at the wheels your looking at about 100HP. As for launching, I would not trust 20 year old equipment to be there when you are racing. I only launch at 1500rpm and slowly let the clutch grab then I shift like a normal person would.

With me it all depends how fast I am trying to rake off. 1500 maybe a little less driving like a granny trying to get good mpg but Ill rev up 4k if I am racing someone.

Yeah ive been driving for a while now though. I drive like a normal person on public roads and im actually pretty good with the clutch. The only reason i ask though is because my grandpa know one of the guys at my local track/strip and i get to make a few passes after hours. Its pretty fun. Being after hours though, the board isnt on so i dont know any real speeds or times haha.

I launch at about 12,000 RPMs. I generally try to feather the throttle to avoid catastrophes. I need a lot more practice.

EDIT: This is generally done on a 600cc sports bike, if anyone was like or .

when i go to the track, usually 1800-2200 preloaded. dont just drop the clutch. thats what destroys stuff.

In the Corolla wagon I launch at 10,000 rpm. And I'm sure I have gone up to 12,000 rpm when we forgot to put the limiter chip in.

What RPM you can launch at will vary depending on a number of factors:
1. how quick your clutch grabs
2. how sticky your tires are (this involves material, tread, temperature, and cleanliness.)
3. the type and condition of the road surface
4. how you handle the clutch (feathering or dropping)
5. how much power your engine is actually putting down, and where in the RPM range it makes peak power.
6. your suspension. If your suspension can't hold the tires on the ground, they will bounce, causing a loss of traction.

The only real way to determine the best launch RPM is through trial and error... at a track. Don't launch on public roads. You might get in trouble with cops, or worse, you might lose control and hurt someone.

Also, a healthy F22A1 with I/H/E should be putting down 120-125whp, maybe more. Unhealthy... yeah, who knows.

Might want to explain clutch preloading a bit.

I noticed a huge improvement in the way my car launches now with the ITRs and snow tires. They're so much lighter than my steelies, plus slightly undersized, so my acceleration is quite quick off the line.

Usually, I'm launching in a 1500-2000 feathered take off, without riding the clutch too much. I like a nice quick snappy getaway.

Launch control is set at 5k....much less stress on the drivetrain than launching lower and I have just enough wheel and clutch slip to take off fast, even with an open diff!
