I'm currently working on a street motor... 357" SBF with Canfield heads and a Vortech YSI and know nothing about blow thru carbs (run EFI) but we would like to try one on this motor. What kind of fuel pressure do you run and do you require a boost sensitive regulator. Also recommend an intake. Jim I will see you for carb (CSU 750?), etc. Any help getting us started is appreciated..:)

Check out the "carb & boost section" over on turbomustangs.com. Tons of stuff you're looking for. CSU does a great bt carb. All I can say on the intake is get a single plane. Fuel pressure needs to be boost referenced with standard 5-7psi base pressure as usual.

I have a CSU 850 for my 88mm turbo project. I bought a Manafuel 500 & an Aeromotive 13202 FPR. with any luck @ all, it will it will work out OK. Im not there yet so I cant tell you for sure.

I am running a CSU 750 and an Aeromotive 13204 regulator. It works great. Hope this helps you.

Brent why are you taking a step "back in time" from efi to carb? even Lutz has gone from carb to efi. since you do "street drive" your car efi will give you more control at varying throttle positions. I feel most guys do blow thru simply because they don't understand efi and don't want to spend the time and $ to learn it (my Opinion).

I'm building this for someone else. I will continue to run my FAST efi... but alot of guys seem to be really successful so we thought we'd try it. It is alot cheaper and he is on a budget. Personally.. I've never even owned a carb... but I appreciate you looking out for me???:p

Jim I will see you for carb (CSU 750?), etc. Any help getting us started is appreciated..:)Jim and I both run Product Eneineering boost reference reglators and fuel pumps. Good stuff! I run 30 to 35 pounds of main line pressure and 7.5 to the carb on the street at 10 to 15 pounds of boost, and at the track I run 45 to 55 pounds of main line pressure and again 7.5 to the carb at the track at 22+ pounds of boost.
I run a Edelbrock 1in. taller Victor JR, plus a 1in. carb spacer. My motor made 9 more hp on the dyno with the spacer N/A.
Feel free to pm me and I will give you my number if you would like to talk more.
Good luck!

I feel most guys do blow thru simply because they don't understand efi and don't want to spend the time and $ to learn it (my Opinion). The reason I run a blow through carb is because I drive mostly on the street non intercooled. It is a fact that a carb has alot cooler air\fuel intake temps than FI in most applications because a carb works as a mechanical intercooler. Sometimes up to 200 degrees cooler depending on your fuel. I would worry more about air\fuel temps, boost and timming control more than better fuel control at varying throttle postions on the street. I use a MSD 7531 Programmable ignition for boost and timming control and is very easy to program with a laptop. ANYONE could do it.
I program and setup CNC machine tools for a living in the US and over seas. I don't think I am" back in time" or don't understand EFI. I think a blowthrough carb works better in my application. (My Opinion)

Well said Mike. Blow thru carbs are not 'old tech'....they are low tech and on the cutting edge right now. Not having to run an intercooler is nice!
