Any suggestions? I'm totally lost in this area. Can I use my stock pump and just get a regulator or do I need a new pump? Do I have to have a fuel return? I can pull my gas tank and weld some bungholes on it for a different setup. What's a good carb shop that will setup a carb for blowthru and not rip me off? Thanks.

These guys are AWESOME with carbs, I have had 2 buddies use them. http://www.pro-system.com/

I hear that these guys are good with blow through apps, but have no personal experience with them. http://www.sd-concepts.com/core/default.htm

in regards to fuel system, it is an issue of how much HP you are going to make. if you know what HP you are going to make you can size the carb, once you have that you can figure out how much fuel you are going to need. both of these places ought to be able to give you recommendations on what to buy & can set you up as well.

I e-mailed Pro-Systems and they said they couldn't help me. Here is their reply from my e-mail I sent them. I basically told them I needed a Blowthru carb (650 4150 style carb) and a fuel pump and a boost referenced regulator and this is what they said. I'm not knocking them in any way so I hope no one gets the wrong idea. I'm just surprised that they don't do them.

HI Brad,


At this point in time we do not build blow through
design for twin turbo applications.

We do not build referencing regulators or pumps.

Sorry, but until we have designs scienced out that are
trouble free and easy to tune they are not avilable
for sale. I hope you understand. The blow through
applications are just very sensitive especially in a
twin application.

Thanks for thinking of us.
