Launching problem

I have searched and found that 3k clutch drops are pretty common for stock/chipped cars. When I try this I jump up nicely, chirp, then bog 2 1k

Any ideas?

Don't hold, then drop.

From a standing start, give it throttle until you hit between 3-4K RPMS, then release the clutch.

I'm not expert stick shift driver, but with my limited experience, a good launch requires that you

know EXACTLY where your friction point it. If you want to launch at ~3k, let up on the clutch until you just about at the friction point, and the second you feel the clutch begining to grab a firm hold, then drop the clutch and give the car some gas. This all happens in a split second of course. =)

Once again, there are much better stick shift drivers on AW. Most of my stick shift driving knowledge developed from me riding a motorcycle, so it may not be correct for cars. One funny thing I'll tell you though, is I dropped my clutch on my bike at 9k rpm the day I broke in my bike at 500mi's. =) The front of the bike jumped up and I almost flipped over backwards. I managed to not fall or scratch the bike, but it scared the crap out of me. The key, I learned that day, is knowing the friction point to the exact millimeter so that I can let inertia do its thing.

Oh yeah, practice makes perfect. Knowing all the technique won't do any good unless you can physically do it!

Turbo engines dont build boost at a steady RPM, so launching is different for a turbo car

you want to build revs, the turbos are boosting when you "goose" the throttle, but they are not boosting when you are holding an RPM.

For an NA car you just hold a RPM and drop the clutch. In our cars, doing this will cause a chirp, and then you will bog.

So, time your launch. If you are launching in, say, 3 seconds, apply throttle to get the tach sweeping past 3k just as you engage the clutch.

To practice this, act like a high school kid revving your engine at a stoplight. Try at the apex of those revs to engage the clutch. You will soon learn that if you can catch it correctly, your car is launch smartly.

When I used to ride (late 70's) we'd drop clutch at 9/10K rpm, boil the tire off the rim... lots

-o-fun.
1978 Kawasaki KZ1000 (kinka like what they rode on "Chips" - except theirs obviously had the police getup)

I quit riding in 1987 for good. Too many a-holes that don't look out for bikes and I'm not so young and stupid anymore
