I don't know many 5AT vortech setups putting out much more than 400whp on 20" wheels at 12psi. I'm not claiming to be the most powerful, but at least I seem to be the norm I guess.

 

Good job man. the 400 club. Thats a good place to be.

How is the trans holding up?

 

Thanks!

The tranny is holding up flawlessly...it'll still chirp 2nd and 3rd even on my 285/30/20 rears.

 

i like it. hope to be there some day

 

Great to see performance like this on an AT. I'm heading that way in a month or so.

 

When i took off my all cog belt Vortech set up . I was at 490whp at 19psi [Mustang dyno] . The AT5 was still holding up but it didnt have many miles with that set up on it . I did have a shift kit [ valve body ] . 400whp is as about as much as you want to have with the AT5 but you really should have a tranny cooler on it .

After 15psi that skinny azz belt keeps breaking . Be satisfied with the 400whp you have . Dont go for more . Its a pain and not worth the hassle .

 

I'm going for more...but not by raising boost. I know it's a problem on these setups so I'm trying to make the engine more efficient now. I just ordered a Water/Meth kit.

 

The other day I raced a BMW 335 6 Speed Coupe that put down 375whp and 400lb/ft of torque and I pulled on him pretty good.

 

I had water/Meth kit on mine also . It will help cool the intake quite a bit . You can add timing and lean it back out . Good luck ! If you need any help I'll be gald to assist if I can .

 

i want a Vortech....
