Mine sure would not. Maybe each car is a little different, would not think it would be that much different. 30psi thru stock heads does not gain you much over 25# since they can't flow anymore.Originally posted by NCTURBOS
That's a completely false statement!! We've used the 009's with a Ta/Te61 on a bunch of cars with no problems up to 30 psi boost and VP C-16, all on cars running 117+ mph through the 1/4 mi. And these are stock head/cam/bottom end/torque converter/intercooler/etc. cars just like his.

This was also using a CAS V4 IC, maybe that helps let in some more air compared to what you had seen.
But saying it is completely false is as false as saying you can run 30psi with 009s and a 60 or 61 turbo, there are other things to be considered.

At 20 pounds of boost, and I'm not quite sure how you plan on doing that on pump gas, those 42's will work just fine.
On my other car and smaller turbo I had to run an additive with 93 oct. at 22-24 psi. Should I get rid get rid of the 60 and get another smaller turbo for the street??
In your opinion, what is the fastest set up for the street on pump gas??
