Looking to twin a 5.9 v8. Looking for full boost at 2000-2500 rpm. Looking to run about 12psi, with some room to go higher if needed. Any ideas on sizes? Ball bearings are out of the question... too much moolah. Anyone know of a good program online to calculate sizes?

Thanks

 

what kind of horsepower are you looking for?

two 48.42s can make a lot.

if you lookin at 700+ two T70s or whatever they are called.

 

Looking to make at least 700-800....
