Any of you road racers planning on trying this on 61mm turbos or any turbos in that size range?
Bruce, on other forums such as DSM and Evo forums, there is a large following for the FP GT35r billet turbos. They seem to consistently show faster spool and more power than a regular GT35r. Have a look at the comparison dynos on this page: http://store.forcedperformance.net/...oduct_Code=NTGT3582HTA&Category_Code=Turbo-FP

I just installed mine (the HTA3586 bigger model), with the SP valve. I'll post up some dynos soon!
a 67 or 71 would be a perfect turbo on the road course with this set up!How much spool will be gained with this valve on a 67mm or a 71mm?
Will the diaphragm melt in the vacuum pot being connected to and being so close to the hot side?
If not, you're golden.
Nice job on coming up with the spool up solution.
Cool.....I'm just concerned because every wastegate actuator I have ever seen was bolted to the cold side.
If it is possible to re-clock the tang on the shaft, I would try to put it on the cold side.
