Turbo ?

[3.8L V-8 eater]

How much difference is their in spool up time between a JB billet wheel turbo and a regular cast wheel BB turbo??? Thinking the new billet wheels should be as good as the some of the first BB non billet wheel turbos

 

[slimtastic]

there is just about no difference in spool time from a billet wheel to a cast wheel, its just about all gonna be in the bearing setup.....or the turbine

Any power difference will come from the wheel design, not from the way it was made. It should make little to no change in the spool time.
