ATS Built ST185

I've had no problem ordering GT35R's with .63 housings -- most recent this past week.

BTW, I have 2 used OEM alltrac trannys on hand if you have need.

I was asking scott to post the uncorrected numbers, not the same plot with STD correction. I'm mostly curious for fuel usage reasons.

Edit: Congrats on the 606whp on your 2! That's awesome!

Garrett doesn't sell a .63 a/r GT35R with the new style GT housings. You can get the old style housing in a .63 A/R through Precision. I don't know that much about Precision turbos, it could be a Presiciion exhaust housing and not a Garrett one? What's the bolt spacing on the .63 exhaust housing you got?

thanks for the congrats. I wish I made it more cleanly, but I've got some weird ignition problems that I haven't had time to trace. Plus my intercooler is maxed out so I am probably going to use a core like this ST185 and put it in the trunk. I've been avoiding going trunk mount for years, but it's the best thing I can think of.

I'll go look for those uncorrected numbers.

They are Garrett housings -- I won't use Precision T3 housings. The exit is the 4-bolt for 3" pipe diameter. I've purchased the 35R from 2 sources with the GT 3" exit in a .63 A/R turbine housing. Perhaps they are getting them separately and not with the housing installed from Garrett, I don't know.

For your gearbox problem, there really should not be one since they handle power well or mine did/does so do the other peoples' I have talked to with high HP All-Tracs. If you are tuning in FWD mode (which kind of sucks makes for a shitty tune). You have to tune only in 3rd gear of higher (no 1st and no 2nd), also no reverse. I am sure you did this too but make sure after you move the selector switch put the bolt back in. The best practice for FWD tuning is grabbing one of those old SW20 gearboxes you likely have lying around the shop and put that in instead which makes for a lot of work but it's better than trashing gearboxes.
