I am thinking of putting a six speed in my car with a new motor. I was just curious how much a stock one can take. I am going to probably be in the 450 - 500 hp range and need to make sure it will hold up.
Thanks

 

I have an article from Muscle Car mag. They talk about an aftermarket T56 that uses convential type clutch and holds a good amount of HP... It has built parts inside that beef it up over stock... I'll see if I can get around to posting it tonight... I think it retail'd like 2300 or 2400 for transmission + shifter.

 

You don't need a beefed up T-56. The T-56 is tough from the factory. GM's rating for the '94-'97 tranny's was 500hp and 450ftlb, but there are guys running 600hp through them at the drag strip and they're holding up fine.

 

There you go... I'll post this anyways just in case someone finds this post in the search archives...


k... the D&D t56s are good to 550 tq and there a pricey 2500 each

(mustang site.... never mind)

 

WTF, $2500?

It's not like Liberty transmission in Texas sells them or $1875 or anything....

 

Mated with a good clutch they can withstand a tremendous amount of abuse and wear and tear. It has been said numerous times that the T-56 is the best manual tranny ever.
