You can get at full throttle on the 2step yes. I do. Others do it at part throttle or 75% throttle.

Were you the same guy that had the driveshaft explode on him at the 1000' mark which popped the car up in the air? If so, that was a scary vid to watch.

I can vouch for this method, as I've done it myself for many years with great success. One of the biggest advantages is that you build up a slight bit of momentum before the car actually trips the lights. I don't have time to explain the timing system in a drag race, but it works. Also, you are fully off the clutch when the car starts moving so you don't waste anytime feathering it out. The consistency is great as well as you are essentially 'dumping the clutch' when you are ready to move since the feathering to prevent shock has already taken place.

I do want to mention now that you shouldn't do this all day long with most clutches as it will definitely wear them out prematurely. If you have a QM, Tilton, etc high dollar carbon carbon clutch or serious race clutch go ahead and do this, the only effect you'll notice is disk wear. If you have an exedy twin BEWARE. It only takes one bad launch on a preload to roast your intermediate plate and cause issues with disengagement. Ask me how I know. lol. Cheap part, huge labor cost. To minimize the effect this has on your clutch, try to only preload for a second or two. Wait for the other guy to tree up before you hit your second staging light.

No, You bring the clutch OUT to where the clutch starts to barely grab and you feel the car barely move, pull the ebrake up and leave the clutch where it was (that friction point) put the car on the 2step, then when ready, release the e-brake and the car will start to move. Once you feel the car move after you have released the e-brake let the clutch out, doesn't need to be a fast clutch let out. Just a nice smooth release.

Yup, soul reason why I parted the talon out. It did over $12,000 worth of damage. It was the t-case that seized up at almost 150mph. T-case broke off and took half the bell housing off of my dogbox and tumbled under the car ripping holes in the floor bored, then got stuck between the rear part of the drive shaft and floor board and bent the driveshaft damn near in half. Then it kicked out and punched through my gas tank and fuel went everywhere.
Needless to say it was a wild ride and scared the wits out of me lol.

As far as pre-loading, you are absolutely correct. I've seen people try to pre-load way to heavily and smoke the clutch or floater plate. No reason to pre load that much, just a little bit gets the job done.

I don't recommend to people doing this on the street or on a daily basis. At the track it's fine since you get maybe 3-5 runs at the track.

The way I always did it was I didn't start pre-loading until I was up on the 2step in the prestage. I would bring it up on the 2step, then start bringing the clutch out, then used the hand brake to bump into the stage.

And single disc clutches will burn up extremely quick doing this, unless you know what your doing.
Thanks for the input man.

That was recorded by yours truly

It was the firt time we had met and glad we did i was very happy to see such a well built 8 sec drag import and can't say enough about how cool you were to me and the rest of us from FFTEC

Oh god, don't remind please lol. Note to self, NEVER BUY AFTERMARKET U-JOINTS!! lol. After that one broke, I started using OEM u-joints, never had an OEM mitsu u-joint come apart on me. That day just sucked all together haha

Thats a great method but it seems that requires a lot of practice . I will try it out

Damn my work computer for not having speakers!! Ill have to watch these videos later. Looks like I have a new method of launching to try out. I have cut plenty of 1.6 60 fts on street tires but a 1.5 60 ft on street tires would be sick!! Especially with less shock on my drivetrain...

That's the only way I launch. Less stress on the entire car. Works every time

Bj, I thought I told you to try this but I can't remember.
