High HP motor & manual trans ?
 

We're dropping a Keith Craft 331 into an 88GT with a Vortec T-Trim supercharger. The question of the day is what manual trans and clutch will hold 600+ RWHP? We called Tremac - their T-5s will only hold 600ft lb of torque.

Re: High HP motor & manual trans ?
 

You got a few choices here. G-Force makes a killer tranny. What ya really need to do is call Walt at Pr-Motion in FLA. (I gotta get my azz to work, I'll post his number later tonight). I'm going to be putting out about 580HP +200 worth of spray. Walt hooked me up with a pro shifted TKO II with all the goodies, and a kevlar clutch. He'll make you go fast, and he's a heck of a nice guy too! :D

how much was that tranny?

Re: High HP motor & manual trans ?
 

Viper T-56 are pretty sweet but they are about 3800. I got the standard version which was 2500 bucks.

Re: High HP motor & manual trans ?
 

how much horsepower could that handle

Re: High HP motor & manual trans ?
 

use a richmond tranny with a mccleod clutch they hold up very well

Re: High HP motor & manual trans ?
 

i think it is rated at 550hp. they have a new terminator listed at 650hp but i'm not sure if it is a 5-speed or 6-speed. G-force makes a t-56 to handle 900 ponies which would be more than enough.

Re: High HP motor & manual trans ?
 

so your standard version is a five speed or six speed? and it can hold 550 horses? also, where did you get it from?

Re: High HP motor & manual trans ?
 

i got it from d&d performance. the standard version swap kit for a 87-93 was 2500 bucks and it can handle 450ft lbs, the viper version was 3800 bucks and it can handle 550 ft lbs

Re: High HP motor & manual trans ?
 

alright, thanks man

Re: High HP motor & manual trans ?
 

I picked up my TKO II for $1250, and then sent it to Walt. He put another $1250 into it, and it'll handle 800HP+ Clutch setup was $300 from him.

Make sure you let us know what you decide on, always interesting to see the different ideas and combinations out there.

Re: High HP motor & manual trans ?
 

We've been looking at the SPEC-III and Mcleod clutches. SPEC-III I think will work, but it's a little tricky running on the street. The Mcleod I'm told will hook all day long whatever you throw at it, and it feels like a stock clutch, but the price is a bit of a killer.

Do you have your updated tranny and clutch installed from Walt? I'm interested in how the clutch pedal feels.

Re: High HP motor & manual trans ?
 

The clutch I'm running right now is a sintered iron clutch. Might as well be hooked up to a toggle switch, it's either ON or OFF. hehehehe Kinda tough on the street, but it works for now. Gonna throw the Kevlar clutch in here next weekend, gettin ready for Fun Ford in Norwalk. :D

Re: High HP motor & manual trans ?
 

That's what I hear about the SPEC clutches, on or off, hook or not. Let me know how the Kevlar clutch goes - good luck at FFW in Norwalk!

Re: High HP motor & manual trans ?
 

Thanks! But I'm gonna use up all my luck getting this thing DONE, let alone when I finally get there! :D

I think we're gonna put both cars in Fast Ford this year, leaving True Street alone.


I will definitely keep you posted on the Kevlar clutch. I talked to Walt yesterday, he said alot of Pure Street guys are running that clutch with great luck.

Re: High HP motor & manual trans ?
 

My son talked to Walt "Da Tranny Man" today, Walt suggested running a Tremmac TKO 600. He said the big guns run this tranny without any problems. He also suggested the Mcleod dual-friction clutch.

I was a little surprised on his trans recommendations, I've heard from others to go with G-Force internals all the way.

Re: High HP motor & manual trans ?
 

They run the TKO 600 that HE'S gone through. That's kinda odd that he suggested the MacLeod clutch though, he's always recommend the Kevlar single disc to me. For BOTH cars even.

Don't want to discourage you, but that strikes me really odd. Did your son happen to ask him about the Kevlar single disc setup?

Re: High HP motor & manual trans ?
 

My son is 19, sometimes teenagers don't volunteer info, I've talked to Jeff at NitroStang Racing, who use to work for ProMotion, and he still buys trannys, the Kuston clutches etc. from Walt. He recommended the G-Force internals for the kind of power we're making.

I might follow-up a call to Walt, to get more details. Did u get your Kevlar single disk clutch installed yet?
