I read this on another forum. Pretty insteresting results:

Hey Guys,

After my bad luck and blowing my motor last year I decided to go with a 383 with my D1SC. This car is on a stock fuel system with a Lingenfelter fuel pump and a kenny bell boost a pump. It is on a 6 rib pulley system also. Other mods to the car are TEA Stage 2.5 Heads, EPP Blower Cam, LT headers, x pipe with a borla catback. The car is also tuned with METH.

DYNOJET DYNO at 10psi.

Wow.. Quite a difference. I've always heard mustang dyno's were pretty conservative. I bet if you ran the same car on the same dyno their would be a pretty significant difference too. Due to engine heat, conditions etc.

 

Wow thats rediculous!

WOW that is far more than I thought it would be... I had 496 on a mustang I think I'm going to try a dynojet now..... 525 sounds way better...
