with 12 lbs of boost on the bd-11A headunit i made 403 rwhp with h/c/i . that was with a foxbody though, but a 5.0 is a 5.0 i guess

 

Foxbody here, numbers are with mods in my sig, with sct tune....no h/c/i yet.......

 

See sig. I made about 7-1/2 pounds of boost with a powerpipe and the 6lb pulley. The 381rwhp was on a 48degree day and this was not correted.

 

Is it going to be a blower that can grow with my setup. In the next couple of years I want to go forged 331. Can you push the powerdyne past 9lbs?

if you are going with a forged 331, the bd11a is definitely not the blower for you. as for pushing it past 9psi, it can be done but powerdyne will not warranty the headunit. they only gaurantee reliability up to 9psi. if you want to go with a powerdyne, the xb1a would be much better suited for your future plans. at that point though, you can also look at the s-trim and novi2000.

 

I made 350 RWHP with my 9 lb Powerdyne kit on a bolt on Cobra, stock heads, intake & cam, for comparison sake.
If you are wanting more power the Powerdyne is not the supercharger to get, it leave some on the table compared to the Vortecs, Novi ect.
