carb for mini blower

You can boost reference any holley.
Here is a link.
I am using a 750 vac secondary on my brand x build.
Start with the timing around 16 initial and 28 max would be a good starting point.
Make damn sure you don't lean the motor out, buy a good wide band meter, and a good fuel pump.

Thanks, I did get the boost ref holley 750 double pumper. I just got my car out today for the first time after a couple of delays, but summit fixed them right away. I don't know how much boost I have, but man this thing is super peppy. And I love the whine it makes. I do have a boost gauge but it does'nt read. I don't know maybe I'm not getting enough boost to register. But theres definetly boost. Some day I will figure out just how much. And go from there.
