    I bet its really quick with that small T70. My buddy dynoed his 331 with a T70 at the end of last year....it would jump up to 18psi and then fall back down to 14psi and hold there. That turbo is to small for a 331. I believe he ended up making 620 or so. Since then he swapped to a 76mm and with no changes the car nailed off 847rwhp @ 19psi.

    Nice. Did you tune the car yourself and dyno to see where your at ?

    I thought all dyno graphs intersected at 5250, is this because of not adjusting for the drivtrain reduction or something?

    HP and TQ are just scaled differently.
