I'm just wondering what can the stock auto tran hold hp and trq wise

 

We have a local guy running a ZZP turbo kit on his auto 2.4 and its a freight train Its been over a couple of years I believe and he still has it

 

Do you know what his numbers are

 

He's on here too, his name is Mindrot, He will be able to give you more info on his setup lol

 

I was told way back in 08, by a good friend of mine, and service manager, that the autos in the balts are very tough. He said I would end up killing the 2.2 before I killed the trans. I do not know if this is true, but he has been the service manager for a dealership for over 20 years.

 

I've heard they can hold up but then I've heard they are weak

 

Although to be fair, ive seen them hold up to alot more if you dont abuse the **** out of it. It's primarily the clutch packs that suffer the most abuse more then anything. The torque converters are 4L60E/65E converters which are capable of supporting alot higher torque.

 

Okay so by this chart when will the trans fail

 

rated to 325 ft*lbs...

 

It's hard to say exactly when a trans will fail, im also not certain why the maximum engine torque is so much lower then the gearbox torque. I know that there is some factor of torque multiplication you have to condition through the converter but it should only be on the order of 1.3 -1.5x on a stock GM converter. I wouldnt trust it over 275-300ft lbs without running raybestos zpack clutches and an upgraded chain. Also dont know much about ZZP's transmissions if you do decide to upgrade. I know a local place here in south jersey that does performance FWD gm transmissions on a regular basis, and their trannys are down right stellar. They shift so fast you dont even realize the car went into the next gear, it feels like a continuous motion of acceleration. So there is alot that can be said about how much GM 4t trannys can be built up.

 

Okay thanks for all the info

Not to hijack your thread, but do they make a stall converter for them?

 

Haha your good that could be useful for me too

 

Since they use the same converter as the 4L60E/65E it is very well possible that an over the shelf performance converter is readily available from yank or precision or TCI, but I wouldnt know specifics, the splines and overall converter diameter could vary from model to model. There are alot of companys out there that will do custom converters for any setup as long as you give them specs. I paid 325 for a custom built converter for a drag honda a few years back from precision of new hampton, the same folks that did jay lenos car. And they will do converters for just about anything with whatever options you want.

This is a pic of my gpnh 3k stall converter I had for my honda....



and i just received my new converter from alliance torque converters for my SS for my supercharger swap, its a rebuilt OEM specced converter built to tighter tolerances.
