For those with an ats manifold, is it worth going to the highflow "extra wide racing flange" or is it a waste of money? What's the difference in price? I've got an appointment to get the truck fixed thursday and I know someone on here will know.
Thanks,
Matt

 

That's for bolting up extra large turbos to the manifold. If you wanted to run a HT3B as a single, for example, you would need that flange. The regular flange is good for all the "normal" turbos - HX-35/40/50s,B1s,HTTs,Phat Shafts, etc.

 

Yeah what Banshee says.
The "race" manifold is for T4 "large foot" turbo's referring to the turbo's large exhaust housing inlet.

Most turbo's made for our trucks are T3 "small foot" ie hx35, hy35, h1c, b1, htb2, sps66, sledpuller 66,

Turbo's with T4 large foots would be: HT3B, HT60, H2E, B2, Big brother etc.

HX55's, Hx40's can have either style foot. PDRhx40's have the T3, Pro52 has a T4.

 

So it looks like I don't need that right now since I have (but really get) to drive this every day. I'm looking to run about 350-400 hp (not sure where I am right now w/ the stuff in the sig) so I don't think I'll be needing a big turbo like that (at least not yet) Any ideas how much power I've got right now? And thanks again for the help.

 

300-325rwhp with the edge comp.

 

How about torque #'s?
