SignUp Now!I run a PT67 P trim on a stock never opened long block. I know that I can't utilize all of it's potential without cam and heads but it pulls real nice. I moved from a GT3255e to it and picked up 9 mph in the quarter with 4 pounds less boost.
I also run a GT67P ( 60-1 ) at 26 lbs (ALKY) with a 3600 stall. Although I have all the support bolt-ons, it's still a stock onopened engine. I's a killer on the street. I know there is more potential with heads etc, but I will wait till I need to open her up. I drive my car very little, so at this stage I am happy.
What is the max boost pressure you would consider running? If you wanted to go to 35psi then you could get away with a 70. Might get a couple passes before replacing head gaskets.
what kinda times are you runing an how is lag with your setup
thanks jay
