breaking trannys?
#2
ha ha yes everyone is breaking trannys
alot the big HP guys go through them but mardi has not broken his current trans which handled his hard launch on slicks to get a 1.72 60ft on his 12.2 @ 112mph pass all he did was cryo treat/shot peen/debur/polish all the gears and shafts
i personally as of friday am on my 4th 5spd although only one was broke do to abuse
1st one got locked in 2nd detent spring lost its tension
2nd one striped 1st gear the day i put the drag radials on
3rd one i couldnt shift into 1st or 2nd but this was to do to EXCESIVE play in the input shaft do to a bad front input shaft bearing
i havnt had one break while spraying but i ussually only spray in 3rd and 4th well and somtimes 2nd for the fun of it
one of the obvious things when going boosted is you have to upgrade the clutch. most go act, spec or clutchnet

wow lets see i usually break 3rd, or 4th gear. But 4th is the really weak one. Once i broke the main shaft and half of it was sticking out of the case!!!! As for clutches i'v broken act street, custom rps ceramic/kevlar, centerforce, and jim wolf organic/metal. Some the rivits ripped out and some with the pressure plate still bolted down i could move the center ring on the disc. But i nolonger have my alignment dowels in the engine block. And i hear that it is possible for the tranny to shift under load without them.

What advatage is it to have a turbo set up that you keep breaking stuff all the time and just replacing it with the same parts, then breaking them again. I don't think it makes much sense to constantly putting down all this power you claim if all you do is break stuff. I like to work on my car as much as the next guy, but you might want to try replacing your busted parts with built ones. Even if your getting a stock tranny and motor for cheap in the long run your spending more money.
great advice

^I dont know about you, I wouldnt call it advice, I'd call this common sense. Go buy some performance parts. Thats what there made for(sorry for sounding like an @ss, but thats not my intent)

i don't blow motors all the time. What i meant was i blew motors way back when i was trying to figure out what combo would work or not. I'v had the same motor now for the past 3 years on 15-18psi pump gas. 25-26 is on race gas for a street race now and then. Back when we had r.i. street races every weekend i would fill with race gas then go to race. Now there are no more local street races- cops put and end to them. So i have not turned up the boost like that for some time. As for built trannys??? Where i tried to find a place to make me custom gears, no luck. So for now it's a spare back up tranny.

you can get the gears cryoed and they'd probably handle quite a bit. also, for our trannies, i'd have IPT install a larger input shaft bearing so that it doesn't break like usual.
