What would be a good converter for the pt-67 turbo p trim, .63A/r. I would like to spool as fast as possible but maintain the proper 650 rpm drop between shifts. I currently stall at 2750 at 0 psi and 3700 at 5 psi but feel a little too much lag for me. What stall would you call thjis? What are you running and what is your stall at 0 psi?
Thanks
Sal

what stall does your turbo supplier suggest for the turbo?

I would call the stall at whatever rpm the car is showing when the brakes won't hold it any longer with the gas on the floor :)

I was told from the supplier 3500 rpms. Flash to 3700 rpms. At 7 psi I am at 3600rpms with my converter but if I push it harder I could probally make 3800rpms.

sounds pretty close to me. Problem is that a street car is going to blow the tires away at boost (or it should if the tune is right), I would suspect, while a car on slicks would be pretty close when leaving against the brake.

Big turbos and loose converters are going to be "slushy" until the boost is on.

A chip with some form of launch control will help from a stop....but, from a roll, the rpm has to come up first.

Not quite sure where the correct 650 rpm comes from...:)
