Fuel pump for draw through + blow through?

[DirtCheapFrank]

So, I'm looking into turboeing my 71 sb with a 1600 dp. I was looking at blow through systems with the stock 34 pict carb, but I couldn't really find anything that made sense to me (I was looking at clonebug and Mike Thompsons systems with the stock pumps but I didn't understand. Any info would help with that). So I'm looking into a draw through system rn until I can maybe understand that. Has anyone done it with a cv carb from a harley davidson? Also could I use a stock mechanical fuel pump? I've seen that clonebug shimmed his up to get more psi. Or would I have to run an electric one?

Any info I'd useful!

Thanks,
Mason (Frank)

Compressor haus uses a Harley style carb for his draw thru amr kits I believe. In draw thru you can use a standard pump as long as the psi is right for that carb or an electric pump. Carter makes some nice "factory" in line pumps that come in 2 different low pressure models. You can use a fpr that is boost referenced if you go electric and blow thru. With a factory pump the idea behind tapping the bottom side of the pump body and having a boost referenced line(after turbo before throttle blade) is that your pump puts out x amount of psi and when the boost kicks in the extra pressure from the turbo bumps up your fuel pressure. I ran a standard fuel pump on my supercharged engine with a single kadron and with a single Rochester carb but I also had a malpassi fpr that I could adjust for the different carbs.

Draw thru vs blow thru comes down to your personal preference and what you want to experiment with and how you want to package it all in your engine bay and most of all having fun doing it!
