The problem with selling off the 502's and doing it proper the first time is that you will not get to learn many of the expensive lessons so many of us have had the opportunity to experience.

I could have done with out some of the lessons.

Vortec Has a great kit IMO. I have one with about 150hrs and its been flawlwss. I recomend changing out stock head gaskets.

Supercharger USA
 
Hey there...I just saw your blog on supercharger usa. They are a manufacturer. I bought two of their 871's for my 36' fountain. Both engines dyno'd out at 890 hp at 5800 rpm. They definitley were a step up from The BLower Shop blowers we took off. They wern't producing the power I wanted and when I contacted TBS, they really couldnt help me out. I was referred to supercharger usa from a friend who had his blower rebuilt by them. He told me that they sold their own blowers so I checked it out. After talking to a guy from there I figured out that he was BDS's old design engineer and pretty much built and designed all BDS's stuff. He was helpful and made me feel really comfortable on purchasing from him. I ended up buying 2 blower kits from them which i have no complaints about!

No, it is confidential.

Not really confidential. I will show you when we get it done.

You are lucky if you are running Procharger's fuel management system.

I'm having a Whipple blower installed by a Mercruiser race engine dealer/builder here in Punta Gorda FL (Flagship Marine Engines) on one of their slightly built 502's in my 29 Scarab. We are only doing 7 to 8 lbs of boost though because of longevity issues and wanting to remain on pump gas.

I was wondering how much of a HP I will realistically get from the blower?
