Launched my car for the first time last night...
This thread sucks and most in here have no clue what they are talking about. Trans brake? No, you give me a break. Why on gods earth would you bring in an automatic trans into this conversation is beyond me.
Pre-load helps save drivetrain parts. There is no question or argument about that. Being able to properly preload and then follow through with proper clutch disengagement is all about PROPERLY launching your car.
Many many many people launch their cars without setting preload, including myself. It becomes more necessary as your HP increases and there aren't too many people in this thread who fall into that realm. When I have big slicks and big hp, you bet your *** i'll be preloading. Otherwise there is no point and you can throw your 60ft time in the garbage.

So with my thread in the drag section, this is whats come up.
Discussing initially about how the driveshaft dropped on his Talon.
This can be found on page 3 of this thread: https://www.evolutionm.net/forums/dr...d-101-how.html
At this point I'm going to reiterate the points that E-brake preloading on a street car, is pointless. Preloading a car with a multi-plate clutch may be viable, but I think it's best for a built vehicle.
I also disagree that it saves any part of the vehicle. Taking the slack out of the driveline saves parts, because it prevents excess force. But adding excess force by preloading doesn't seem to be viable for drivetrain longevity, and none of you have really stated how that would work? Though, I'm open to thoughts on the matter (not trying to be a dick... I genuinely would like to learn)
I sure as heck am not going to sit here and say that my method is the end all be all way to launch an evo, because it isn't, and it isn't my method. I just don't think people should be launching a stock Evo using the parking brake. Though I would encourage you to read through the thread that I posted to see how to properly do it if you have a desire to try.

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.

The cutest part of your rebuttal was the qoute you used from that thread with all the damage LOL... he popped his DS at the track from using cheap non OEM u joints. So that quote was worthless.
When you're ready, just let me know!!

This guy is asking about how to properly launch his Evo that is mostly stock, and you're telling him to use the ebrake?
I'm not here saying anything about not using the ebrake. If you think it works, thats great. In fact I'm positive that it works, because Evos are using it. The issue isn't whether or not it works, the issue is whether or not this individual should be using it. If a guy is looking to haul a pile of leaves to the dump and needs a vehicle, a dump truck would work, a tractor trailer would work, but those probably aren't the best options for someone who doesn't have a purpose for something like that. Similarly, this individual, as well as anyone who is learning to drive their car, has no purpose for using the ebrake to launch. I still maintain that unless you have a built drivetrain, there's no reason to use the parking brake and IN the thread that I posted for reference, even THEY specifically say that if you have a single disc clutch, it isn't a very good idea? So I'm ready. Tell me something useful besides just "I'm right you're wrong".
He specifically states that that driveshaft broke from using cheap joints. I wasn't trying to hide that, I quoted the entire post. I in fact ENCOURAGED people to read through that entire thread.
I've presented my side of the argument, and I've been polite doing so. You seem to be constantly suggesting that I'm wrong, but all you've really stated was that you were going to have me blow you because I somehow proved you right?
Try offering something constructive instead of just shooting your mouth off? This is the single biggest problem on this forum. Tweens that just want to, I believe you put it best, "e-thug". SMH.

Does anyone have any experiance with multiple drop launches? Ive launched mine several times and dropping it gives a little wheelspin and then takes right off... however it lead me to a new tranny.
I've never dropped durring a launch but slipped. I did about 15 or so launches this past summer on my Exedy Twin and it still works great. 12.0 not bad
Now when I did on my stock clutch...i had to replace it at 13,000 miles.

put the car in first, find where the clutch grabs and hold it there. floor the gas. rpm's will bounce off limiter, slowly slip the clutch until you feel it grab, then let go. should be a quick slip/dump. you should still have the gas pinned to the floor. DO NOT come off the gas until it's time to shift.
simple.
Once you get launching down you'll feel a lot better about it. My car in it's current form (Stock trans, twin disk, stock diffs,) has seen over 100 launches from Autocross, track, and street. I've only broke once and it was on the very first launch I did with the car due to my negligence. I then replaced everything but the clutch with OEM components.

Mind explaining to everyone exactly what you did to break it? Did you just drop the clutch or what? Firsthand experience is the best way to prevent others from making the same mistake!
There's no egging me on. Its just ignorant people that annoy me.
I gave my argument, he said that's dumb. Theres plenty of evidence that I gave back and he then changed his argument to, they have built drive train. I don't really give a ****.
Pretty sure I'm older than you and Have built more cars than you. But that's a whole other thread!!
