just curious if anyone on here has delt much with Blow Thru carbs. Dont know much about them but as always i am thirsty for knowledge. What makes a carb a "blow thru"? how do you convert a regular carb to a blow thru? (ive heard it isnt too hard with holley double pumpers)
Any other info would be cool as well.
EDIT: only after i post do i find something :roll:

Might wanna ask 90 Notch, or some of the MSCA guys.
Also Malibu is doing some reading up on the whole thing...he can probably give you some good information.

best way is to build a box around them and pressurize the whole thing. Otherwise I think you just need to pressurize the bowls and seal the shafts. I think both setups need a 1:1 pressure regulator too.
Maximum Boost by Corky Bell goes into it a bit.

A carb with Annular boosters is a must! Down leg and straight leg boosters are not sesitve enough for a forced induction setup. Investing in a blow through carb and a boost refrence regulator. carb hats will go over your bowl vent tubes so everything will become pressureized.

Well, i am still debating to be honest. I woulkd like to go blow thru carb for the cimplicity of it. No damn wiring/ecm or any of that shit to deal with. However i started a bit of an arguement as people say that for the $600 i will spend on a blow thru carb that i could go with a TPI setup, which in some minds is far superior to carb. I know blow thru setups are capable as if im not mistaken there is a blow thru setup that recently broke into the 7's.
Just trying to decide what would be best for me. I like having fuel injection as you get feedback and it can tell you more than a carb, however i dont know if that is worth the trouble, if i just buy a blow thru carn and have it tuned by someone who knows their shit then i wont really have to worry about it.
As of right now the plan is a Demon 850, i Will probablr be getting mine through " Vic Hubbard Speend and Marine" as they are $532 and im not to excited about ebay since some stupid bitch got a $400 hold on my paypal account.
anyways heres an ebay link to the carb i like:

If I was you I'd get on stevemorrisracingengines.com, get their contact number and call it. He's a really nice guy, super knowledgable, and I believe he'll sell you a blowthrough carb you'll need based on your combination, I've talked to him before, he's really helpful.
