Rusty67 said:Is this a street car or a track only car ? What rear end/gears are you using and what tires are you using on the car.
The reason I'm asking this is, if you are building a street car it will change what parts you should use internally for the trans.

WashburnGT said:your everyday T56 should be able to handle around 450 lb-ft of torque. If you get a viper-spec T56 they say it should be able to handle well over 550 lb-ft. ALthough there have been terminators making 500-600 on regular T56s...now whether or not that is a ticking timebomb...I dont know. But those are the numbers claimed by Tremec.
Edit: Im sure SVTtech will come on this thread and be able to tell you exactly what a T56 can and cant handle...
Rusty67 said:Sounds like you are going to be streeting some serious HP. I would recomend geting some high nickle content internals for the trans. Then again it all depends on how you drive it. I've seen a stock non-world class T5 take a lot of daily driving/HP and 3650s blow up in under 10,000 miles. If you are just gonna drive the car you might get away with it. If you are going to be hard on the trans then definately upgrade it.
You also should put in a drive shaft saftey loop and an upgraded drive shaft as well as considering a stronger rear end. If you are hard on it, I don't know how long an 8.8 will last behind 500+ HP.
ummm I know 2 that have fragged t56's. One only mods were or mid and catback. Other well I know the car makes over 600rwhp on the dyno and he fragged the top of the line D&D t56 upgraded tranny.thomas91169 said:i dont know exactly, but ive yet to hear of a 03/04 owner blowing one up.
No. Both 03 & 04's utilized the same 8.8 IRS.Rusty67 said:I had heard that the 04 had switched to a solid axle 9" but I can't confirm it either way.
Rusty67 said:I think the 04 Cobra had a solid rear axle and it was a 9". I think that would bolt right into your setup. Yer car doesn't have IRS does it ?
Uncle Meat said:No. Both 03 & 04's utilized the same 8.8 IRS.
The weak point on the Cobra T56 was the stock 10-spline input shaft. The Viper spec'd T56's have a 26-spline input shaft on them which gives it a higher torque rating. Many 03/04 Cobra owners have updated their input shafts from 10 to 26 spline units from Liberty Gears.
The T56 is a pretty tough tranny and holds up well under high HP applications. As long as you're not power-shifting the car at those high levels the tranny should hold up. Now getting a clutch to hold that power and last for a while may be a bigger problem...
