Launching with an on/off clutch???
 

Interested in what everyone else is doing. When I had organic STI clutch it felt super fast to preload on handbrake and then release with about 5000rpm on board and lots of preload.

Now with my button ceramic and much more power the preload is almost impossible to achieve due to the on/off clutch.

What is the best technique if your not concerned about your box or clutch but dont want to break driveshafts.

I was thinking
1. Ride clutch with handbrake up for a sec to preload the parts.
2. With handbrake still up rev to the RPM required eg 4500 but without riding the clutch at all. Just holding it in.
3. Release handbrake as your release the clutch smoothly but fast and hang on.

Does this sound right?

Ask rogercordia.

Wheelspin is your friend :D :D :D

Or your driveshafts anyway. Surely a driveshaft is going to be cheaper than a box???

Seriously, he has a forum.

6000rpm side step.

Thats how i smashed the front axle on the last run at motoplex ,

Ride clutch with handbrake up for a sec to preload the parts.

Hold up, 6000rpm sidestep ruined your driveshaft, or the preload technique?

I've heard the preload technique is a bit dodgy on centre diffs? I've only ever launched once and that was the preload technique, felt fine.

I smashed my front axle in half with the 6000rpm side step and no preload technique. I think maybe preload and then sidestep slightly slower might be the go.

Only way to do it :)

noob question...
I'm guessing preloading is like when a rear wheel drive car will accelerate and brake on the starting line, so how does that work in a manual AWD car? wouldn't that just kill your clutch?
