Where is the best place in Texas to get my transmission built?

I'm looking to retain my 6 speed, yet be able to hold over 1400rwhp.

Is there such a place? Do any of you guys have built T-56's... any problems?

Recommendations please...

[psiperformance]

I smell a troll anyone who knows enough to make 1400 rwhp definatly should know where to go to get a trany like this built seen as how they are here in texas and near you

t-56 rebuilds also known as six speeds inc

Six Speeds, Inc.

your other choice would be the rockland standard transzilla t-56

What are you putting this into ?

Not a Troll...

Got a blown cammed billett rodded 302 stroker in my Cobra. I'm planning on turbos, but one if the Syncro's in going out in 4th.

I've had a couple of quotes from places, I was just fishing around to see if there was anywhere I'd missed and seeing if I could find any more info on them. Most of the readily available information in build transmissions seems to be all auto stuff.

Six Speeds, Inc. is a name that seems to be recurring... it's getting close to the top of the list.

Just for entertainment surposes I will throw my hat into the ring . You will need a minimum of a Viper spec'd T56 . This will involve upgrading the input and out shafts to larger diameter shafts as found in the Dodge Viper . Unit built like this should be good for about 1000 rwhp depending on the weight of the vehicle . You are talking about 1400 rwhp and I am sure its not going to be some gutted out race car so lets use 3500 lbs as the mark for the weight of the car . If thats the case you will have three major issues in front of you ......

(1) the stock bellhousing will not fly so you will need a steel scatter shield
(2) a stock style clutch and flywheel will not fly either so you will a minimum of a twin disc setup for race only applications with a billet steel or aluminum flywheel at the very least .
(3) I doubt a stock set of T56 gears will hold up in that weight of a vehicle at that horsepower and torque level so get ready to shell out about $7,000 for a serious T56 (maybe a little more)

If all of those things sound good to you ... call me 210-887-7615

holy shit 7 grand dam it cost alot to go fast.wish i had it like that

[s_x_i]

Thank you!

That was the kind of response I was looking for.

Yes, the car is gutted. I still have the IRS, it's got the full 'Red Pill' treatment I was hoping to open track as well as Drag race, but I don't know if I'll end up doing one more than the other yet.

You always hear of Twin Screw Cobras making 600rwhp, the transmissions seem to do ok at that power level. There are alot fewer of them that have crossed the 7, 8, 9, and 1000 rwhp mark.

I'm in the mid 600's right now on the lowest boost setting. Before I turn up the twin screw, or eventually bolt on turbos, I need to make sure my transmission and fuel are up to the task. There really isn't that much info on built T-56's

If a Viper Tranny is good to 1000rwhp, I'll probably do that first and then see what the future, the racing, and the budget all do to me.

What kind of costs would I be looking at to upgrade my stock T-56 to viper internals? I have a centerforce DFX clutch and 26 spline input shaft.

Thanks again Mike!

You are looking at $1910.00 to build your unit to Viper Specs .

[s_x_i]

That's definately within the budget!

Let me get the cage in her and I'll be in touch over the next couple of weeks.

[thesource]

Let me know . Its going to take a couple of weeks to get it done versus a standard rebuild . The rear housing will need to be bored out for the larger rear shaft and bushing .

I have a viper spec T-56 in my car and have had zero issues. It's only low 600's at the wheels, but it's a 4000lb+ car that sees some heavy use.
A DFX clutch will not last long. I've gone through two of them.

I highly recommend a twin disc setup. I'm running the RAM Twin 900 (rated at 1100hp I think). NO chatter, 1/4 of the pedal effort of the stock clutch and it holds the power.

There's a HUGE difference between tranny requirements for a 600-850hp car compared to a 1400hp car. There's a reason everyone goes auto after a certain point.

What do you mean "lowest boost setting on a twin screw". You're making mid 600's on 8lbs? What kind of times are you running now?

[s_x_i]

666/646@14psi... lowest setting I have it pullied for.

Haven't had the pleasure of track times on this set up... I've had a few bad runs of luck with the car. No sooner is one thing fixed, than another breaks or something shitty happens.

It's off the road right now getting a nose job, whilst I'm doing that, I'm putting a cage in it. The transmission started to go out a couple of days before I bumped the front end, but I was hoping to nurse it down the track for some base times.

Ahh well... I'll just keep on fixing it...

you dont open track with 1400 rwhp, that is just not happening. you will need lower boost and a traction control device to feed in power

Yeah that will be a hand full for sure .

[Sonic Blue 85]

Yall beat me to that one. I was going to say, the day you want to take a car with 1400rwhp and do an open track day let me know so I can bring a video camera. Because it won't last long. I don't know if the half shafts will hold up to that kind of hp, with much weight and traction or wheel hop. I would be surprised if a viper spec T56 would hold up long at that power level. The only manual that I would try behind something that make 1400rwhp would be a Doug Nash based trans, probably some variation of a G Force five speed.

Lol - i know that! The plan is for turbos and I'd turn the boost wayyyy down for open track stuff.

I may well end up buildint two cars when all's said and done.

Sorry, but there's no way you're making those numbers on a 2.6 @ 14psi.
