Ok i no this has been talked about before, but at what level of hp/tq should you go to a 58mm tb. would this upgread be worth it for me . just so people know my numbers in my sig are low going back to the dyno soon.

 

at what power level is a 58mm tb worth putting on?

 

like 500+ rwhp...H/C....blower...N2O...

 

I don't know at what power level but I know we don't need them. To take a shot at it I would say upwards of 450rwh.
