Got My Turbo Hi Flowed And Inside The Front Housing The Marks From Bouring It Out Feel Like 36 Grit Sand Paper Should It Be Smoother than that?

you wont notice much if you did smooth it, the boundary layer takes care of many surface irregularities or rather it gets in the way so minor issues wont be important, if however you were doing this to the max then you would smooth it *and* make sure each and every transition between items was perfectly smooth - then you might get as much as a 2 to 5% improvement at the top end and then only when resonance comes into play for max flow...

thanks for that info

i got my turbo hiflowed by MTQ and the inlet is smooth as with only small tracing marks. but like mike said because its on the inlet side of the turbo shouldnt be a real problem as the boundary layer will be fairly disturbed anyway.

when i had all the boys over we were all drunk i shoved my pippi in the front of the turbo, it didnt get and scratches on it so i guess its pretty smooth Some original photos have not been recovered yet.
