i am planning on forced induction and was wondering what a safe number to aim for is. i will be getting a transgo kit for the 700r4 so without having to upgrade anything else how much do you think it can handle?

 

GM rates them for 300hp. Not sure if the v6 trans will hold up the same, internals are slightly different. I did a thread called "Improving early th700's" a while back that has some useful info you might want to check out.

 

never really thought about it, im a if it breaks ill replace it type of guy, i drive quite sympatheticlly anyways. most of the time. ;-)
what about the t5

 

Even lower on power rating. They never put them behind any 350s they were so weak.

 

Ive heard that the V8 700r4 and V6 700r4 internals were the same, the bellhousing is just different. Did I get the wrong info?

 

I heard the same thing. I know that the older ones are weaker though before a certain year.

 

im sure the t5 can be rebuilt much beter, i know of a few cars which had the t5 and buckets of power/torque. over the pond cosworth springs to mind....

 

yeah i wasnt looking to replace the tranny, but did plan on a trasngo. so with the shift kit 300hp is manageable you say?

 

The early v8 and v6 th700's are the same, but later v8 models use beefier internals (30 spline input shaft and other hardware). I'm not entirely certain, but I don't believe the v6 trans benefited from the later components. Your trans should put up with 300hp depending on it's condition.

 

T-5 are ****

HOW TO BREAK A T-5 in less than an hour

1. bolt T-5 to a stock LT1 (using the LT1 as example due low end power)
2. powershift your T-5
3. If you stop moving the fun is over and your T-5 is dead already
4. open up the T-5 and see what you have destroyed
5. cry because you should of bolted up a T-56 to our LT1

It doesn't matter if your T-5 is bolted to a 60* V6 or a LT1, it will break if you abuse it

i know stock i could blow it easily !!

 

[quote=zs&tas;3723576]No point just buy a T-56 or a TKO 600, though the Getrag type 233 V160/161 were difficuilt to break on a MKIV, i've heard stories of those stock 6 spd holding up to 1000rwhp
