Umm who knows? It depends on how much power you have, what disk you have and how you drive it. Wether you launch alot or slip it alot.

Cool cool, i usually don't launch it because since its still mostly stock i try to take it easy, since i'm getting DSM Link in about 3 weeks i'm gonna wait it out so i can do better launches with more power build up... 2-Step FTW!!

Sadly i agree with you... i know that hard launches and DSMs don't go well together. I'm only running an EVO III 16G with external Wastegate, but once i ad the bigger injectors, pump, and the link. Its gonna get a tad bit hairy.

That clutch will be fine with a 16g. Honestly, if anything you might need a new disk after a while, but those are cheap at $100. I had a street disk, put on probably 8k hard miles on it, with launches that netted a mediocre 1.60 60', but it held fine until the day i took it out. I wouldn't be concerned with a 16g.

Here's the big question... Sometime between now and mid next year i'll be upgrading to a 63 trim, with a 44mm external. Thats probably when the drivetrain upgrades should begin right...?

as long as you got a 4 bolt rear you will be ok, main problem i see happening is the center differential. I would look into a 4 spider or welded diff. Give www.dogboxracing.com a call and get your trans freshened up, and you will be set. That clutch will hold 450+ ft lbs of torque

All the Tough Tranny's are is new OEM synchros and what not. The big one is the syder gear. If you trust a local Tranny/Driveline shop go talk to them and see what you can work out.

yea i've heard of installing those but never really looked into it, i have a spare trannsmission, i may send that one to shep. Until then i guess i'll keep it under 400hp... And to answer northendtrooper, i don't really know how to pre-load a launch with the handbrake... i'd like to know how to though

Ok

A: All shep does is replace with new OEM syncrhos and Gears thats it. Anybody can do it. What makes him part from everyone else is the Dogbox.

B: To pre-load a launch.
As you are on the line watch the tree. Put your car into 1st gear and pull the hand brake making sure you keep your thumb on the button so it doesn't lock (you'll look like a complete idiot trying to rip out with your handbrake on!) Then with your left foot on the Clutch and your right on the gas. Time the tree so you can put on the 2 step as your 2 step is going start to engage the clutch ever so slight to feel the hand brake being used. Then once you have the timing down, fully engage the Clutch along with dropping the handbrake. This will launch your ass into the back of your seat along with decreasing the chance of snapping a driveline out of the hole. Note this will drecrease the life of your clutch so do it sparingly.

act 2900 is garbage. As i stated before, they are good clutches up to a 2600 and around 400 hp. I went through at least 3-4 disks and 2 pressure plates last season and never made it to the track. Everytime i did a pull on the dyno my clutch would lose pedal pressure and would not allow me to go into gear. Take it on the highway and do a roller and by 4th gear the tranny was grinding because the clutch would not disengage. I know act is the only "real" clutches dsm'rs use alot like the walbro 255, but i did not have good luck with them at all. I since stepped it up to a PTT twin disk. I still dont see why you would run a 2900 with a 16g?

If you do a new clutch try an Excedy Clutch heard they're pretty damn good.
Also Sounds like Purple is having way bad luck! haha sorry to hear that bro. It could be also your Slave Cylinder is going out.

I'm still trying to time my launch haha so I'm in the same boat with you.

Haha hey man you know how it is with DSMs, "if something isn't broken or in the process of breaking, it isn't a real DSM"
