hello
anyone know the sweet spot for one of Cottons 65 turbos. I had the boost up to 23 this weekend and it did not pull any harder than the te44 I had on there running 21.
Thanks

Wouldn't it make more sense to talk to Jack to see what your need to do with whatever mods you have to run that turbo?
 
With a set of GN1's and the cpt65....55lb injectors.

11.60@116...19 lbs of boost 94 octane only

Never turned it up,Because of no rollbar,And It was fast enough for me on 94 octane.But I felt It would of been a solid 10 sec car with 26lbs or so.
 
I ran 10.70/80's at 25 psi on iron heads with one Spooled stupidly fast. Faster than stock. I had a 3000 convertor. I could have used the stock one.
