Trying to make a decision to upgrade my BD-11a to the 928 Motorsports Super Powerdyne rebuild or just get a gear driven SC to finish up my Spring project.

Has anyone gotten this upgrade?

How does it compare to the original BD-11a?
Any dyno results?

Your thoughts will be appreciated.

Hold On

I have 20K on mine with no problems. Since I purchased it that way I have no comparison. I think the high speed bearing, belt and the vents are good insurance. I dropped down some on the front pully without over spinning the S/C

There are a few You-tube Videos about the Powerdyne with our upgrade impeller on it. You should be able to search "Super-Powerdyne" or "Powerdyne Impeller"and find them,if that helps.

You Tube. Will do.

Carl what is the difference between yours and Murfs ?

Carl Fausett

Not sure I understand the question. Murph does not rebuild or upgrade superchargers.

RCinXS is asking about expereiences with our upgraded impeller in a Powerdyen supercharger.
