Question on horsepower

['94IDITurbo7.3]

A buddy of mine has a 6.4 that is running a 72 mm atmo, stock high pressure turbo, river city stage 1 cam, and stock fuel. What kind of horsepower would that make roughly?

Thanks

Jeff from ******* made 641 with a 71 and jd dynoed 694 with a 72mm. Also the track times (low 12s at 108+) back up mid 600s

Depends on the tune and healthiness of the fuel system. Low-mid 600's.

Anywhere in the 600's really...every truck is different. JD did 694 on a 72 drop in way back when.....others have done only like 615. Just depends on the truck. And the dyno. And how healthy the HPFP is.
