I need advice on launching my car so i don't break another transmission

[97-gst]

I recently converted my gst to awd and this coming up friday is the last day that the tracks gonna be open. Ive brought my car there twice when it was fwd and both times i ended up throwing stuff through the bell housing on the transmission. This time im gonna be using Dsmlink and gonna try to launch at 4k. So should i let the clutch out until it starts to grab and then hold it there, hold the gas wide open and then when i take off should i burn the the clutch or just sidestep/dump it? This will be my first time down the track on the e316g and the track is just a 1/8 mile, so im shooting for a 8 something. Btw ive got a stage 3 zoom clutch

Let the clutch slip.

Do the two step/anti-lag launch, but when you let the clutch out, keep your foot in it and then once the car moves forward bring the clutch out too.

I'm making quite a bit of power, on a factory trans. The next pass I make i WILL trap over 130 and have a 1.6 60 foot.... factory trans.

Never sidestep or just dump it. eat up the clutch disc, not the trans. discs are less than trans.

alright thanks, but what rpm should i launch from?

I think my antilag is set at 5.5 but just rid the clutch a little out of the hole till you get use to it. Launching is def. the hardest part, once you figure it out you will be golden.

This is the most concerning issue I have even though I have a TRE tranny. Slipping the clutch/ launching is still getting me because I can't slip the clutch quick enough to help me on the track. I guess I will just have to go out one night and keep doing it over and over and finding the special "place" where it starts to let go a little and I can know where it is.

I preload just about any manual car I launch. Here is what to do:

Move forward to turn on the first set of lights.
Push the clutch in and floor it since you have dsmlink.
Pull up the e-brake.
Let off the clutch a little so that you feel the car trying to over power the e-brake.
Let off the clutch e-brake some so the car can move forward and turn on the second lights.
Now you can let off the clutch a little more so your car is squatting in the back.
Lights turn green
Drop the e-brake handle and at the same time quickly (don't dump) release the clutch.


This will prevent the gears from slamming into each other when you launch. This is because they are already against eachother. This will wear your clutch out quicker than normal.

thats some good advice, im gonna deff try this

Be cautious with the above method. It is the CORRECT method, but if your car is a daily driver, it'll fry your clutch pretty quickly.

 

[97-gst]

yeah this my dd, so should i just burn the clutch and not use the ebrake

 

[schroder]

The Ebrake technique requires you to burn your clutch. The way I always did it, and never fried anything but a clutch was simply slipping the clutch. Unless you have a very high quality clutch that can dissipate heat very quickly, slipping the clutch the whole time your sitting on the line will fry it pretty quickly. Whereas slipping it out of the hole and then letting it out after it starts moving burns it up less, but still saves some of your clutch life.

To get a good launch, and not break the trans a puck disk helps a lot. With an organic disk, when i get a good launch it slips down the track. The more you slip a puck disk on the launch, the hotter it gets, and the better it holds down the track.

pull up.. light the FIRST Yellow on the staging light.

pull the stanging brake/ebrake etc.

sit on the 2 step and build some boost.

creep up using the stanging brake till you light the SECOND yellow

when the tree drops you will be ready to let the clutch out as you release the stanging brake, you do this all in one smooth motion, you stay wide open.

Done, no driveline shock, no 'dumping'.

This is not necessarily true. I had a puck disc and it could still have trouble gripping if I slipped too long. I was on the verge of having too much power for it tho. The big difference between the puck and the organic, as he said, is heat dissipation. Even when mine slipped a lot out of the hole, I could still slam gears and not have it slip there.

On an organic, when it starts slippin, it keeps slippin.

Ill try this..i only plan on making 2-3 passes because i really dont want to break something

Since it is your DD your probably best off just slipping the clutch. Replacing a clutch is much cheaper than replacing or rebuilding your tranny. I don't wanna take credit for this but I'm not sure who said but....Think of the clutch as a fuse for your tranny. If you just dump the clutch your essentially bypassing that fuse

 

[97-gst]

Cool... yeah as you can tell i ran my car and i didnt break anything thanks guys, i used the method of using the ebrake and getting on the launch controller and holding it to where the clutch started grabbing then i slammed the ebrake on the green light and rode the clutch out. Worked out great thanks again guys...

you only have to let the clutch drag ever so lightly to preload the tranny. Drag it too hard and it will overheat and slip
