I'm thinking it would require alot more fuel pressure,
once it gets into boost, than if it's mounted above the supercharger.(normal atmospheric)

Thanks for the info and the answers,
my only hands on experience has been with
centrifugals/efi on drag cars and we always ran fuel after the blower
and never needed fuel to cool or seal the blowers even at 25+ psi/1000+hp.
Guess roots blowers are a whole other ballgame,
As for fuel injectors we used boost referenced regulators which
raised FP as boost went up keeping the flow from the injectors
same.

Finally got around to taking some pics of the finished product. I hard coat anodized everything including the fuel rails, injector plates, carb adapter, etc. I'm pretty pleased with the way it came out. I didn't think it would look that good polished against a black blower.
This will also bolt right up to a roots blower or top entry Whipple, not just the PSI.
Thanks. Enjoy.

Those turned out nice Eddie. I always amazed when I see the PSI blowers just how big they are.

You know......I'm sad to say that I don't know. The owner just sent the blowers to me so I could get started on building the injection. We have talked about so many different options, that I'm really not sure what they are going on. I believe we are using some existing engines. Maybe he will chime in and shed some light on it. Thanks

I took the first one I got my hands on to play with and put it next to a 3.3 L Whipple. It was like comparing a Weind 177 to a 14-71. Just no comparison in size. (certainly not a knock against a 3.3 Whipple)
