Looks great! I don't know how hp #'s compare from turbo to roots supercharger but we dynoed my 540 BAE fathead fully moded k-11 superman @50 over. Best #'s were 2153hp.It was to lean for what we need.So we had to add fuel. It was living well in the 1800hp range on the dyno. I heard all kinds of numbers before we ran it but thats what it made.I would be very interested to here some real world dynoed turbo motor numbers.Good luck with your combo!My motor was 39lbs of boost. What version of brads heads are you running?
