Dyno sheet of an NRHS Twin cam
I know it is not a Sportser but this is a twin cam we just did work on and I am really pleased with the results:
This is our new NRHS stage 2 twin cam headwork (1.900 Intake and 1.615 exhaust valves) NRHS Hurricane 107" pistons using stock cylinders (10.2:1 cr) and S&S 585 chain drive cams. This was a really mild build and very cost effective. We are seeing similar power gains with our XL headwork.

around 70 hp stock is what I have seen.
if you notice the dyno operator shut it down really early at 5700 rpms. I think he could have got 115-120 hp out of it if he pushed it just a bit more.

Waiting on customers to send me their dyno sheets. That way you know they are honest results if they are done by an independent dyno.
