Anyone have any experience with these set ups. I ran across one here locally. It looks like a blower bolted to a stock type upper mpi manifold. Good/bad? It comes with everything even and ECM and fuel pump. What kind of power and reliability compaired to a procharger?

Thanks

i have seen them but never worked on one,,you will get more usable power out of a pro charger and better fuel economy..

Anyone ever use them.

Anyone????

The 250s are small and spin fast creating heat. They are not the most durable superchargers either. On a 502 you would be better off with a 671 setup. Although if you dont have the hatch space for a 671 or 871 the 250 would be an OK option I guess.

BTW, merc used them stock.

Thanks for the info

One on eBay now.

There has been 2 on ebay one starting at 1800, and the other at 21 or 2200. both say there compleat. There is also a pro charger m3 set up on there for 3500......

I would say go with the procharger if it is set up right the power is awsome.

I put a weiand 256 (same basic size as B&M 250) on my 509,ran the stock pulleys (5lbs of boost) and picked up 12mph (70 to 82) with no other changes except changing prop to match the new power..
Maybe thats not enough for some guys but for the cost I thought it worked just fine and none of the pain in the ass tuning of a procharger..
