hello everyone... i have just started aquiring parts for a junkyard supercharged 7 project i plan to start quite soon. i have an intake for a 6 port which has had all 6 port materials removed. its basicly just a plain, strait through 6 port manifold. it also has been hand made to sit below a 4 bbl carb. to hell with fuel injection for a little bit, i'll worry about that stuff on my turbo car.

anyways, i plan on building up a 6 port motor with a supercharger and a 4 bbl on top. my question is, what type of fuel system should i use? i was planning to run about a 600 CFM on the motor all natural with a half bridge or something. im no longer looking for the half bridge power. i want to try a supercharger- M90, most likely- but i have no clue what i'll do for fuel. i think the 600 carb will do fine but, what should i do to make the carb keep up with the boost and such? if this was fuel injected, i'd just use the bigger injectors and such but im on a budget kind of, so im goin with a big carb. i dont know if i've given enough background here so feel free to ask and i'll answer what i can. i appreciate any input.

 

holley 950 cfm carb will keep up with that boost

 

that im sure would be a little over kill. i need somethin like a boost deficient fuel pressure raiser or something but i dont know what size or ratio i would need or what kind of fuel pump is compatible with that.

 

just block the secondaries off until you need more power for boost

 

The m90 isn't designed for that. If you run the m90 use the stock fuel injection with larger injectors, and an s-afc or use a standalone.

 

this is on a budget.... the 4 bbl will work fine. i've just got to figure out what kind of FMU i will need for the carb. i was hoping that someone in here knew a little about carbing rotaries. i have a local guy that i can talk to who used to have a supercharged rotary but he was using a procharger and had money, unlike me. im trying not to go over 1000$ with this until i blow the motor or somethin. i got the manifold for basicly free. now i need a really cheap base model with a busted rear end or somethin of that such. i've got all the 5 lug swap parts between my turbo or my GXL.
anyways, tjgosurf, what are you sayin about blocking the secondaries?
