- Today I will be showing you guys how to build your very own diy blow through carburetor. The carburetor we are working with is an old school barry grant 650 demon. This particular demon was an alcohol carburetor that I had converted to gasoline and then later converted to e85. I've been running this set up for about 7 months and so far I've had no issues. Last time I was on the dyno I put down 529hp and 509lb ft of torque. Engine specs are stage 1 cam (.553/.553 208/212 112LSA), carbureted dual plane intake, 2 inch spacer, 4 inch carb hat spacer, budget turbo carb hat, ebay 78/75 turbo, shorty headers, stock bottom end, stock 862 heads with valve springs, Daytona sensors LS2 coils, Daytona sensors smart spark LS ignition system. This is only part one of the carburetor build on the junkyard LS. Part 2 coming out of the turbo carburetor releasing soon.
I don't think I really need to say this but if you mod you carburetor for blow through, you void any warranty that applies to the carb. DO AT YOUR OWN RISK!

Night Wrencher!!! Good stuff Brother. Thanks for sharing with us. Thanks for dropping links on all this stuff in video. Blessings to you and yours, and cheers from Motown/Dearborn
Thank you sir! Theres more coming out soon!
I have been considering building my first blowthru set up for a long time. It will be a relatively mild setup, 8 to 10 lbs max, I will have a long learning curve to go thru and that OK by me. This video was easy to follow, and that's what I needed to see. Thanks, on to part 2!
Very well made, you have a great way to explain all the details! Thanks buddy
Thank you sir! I really appreciate it!
The fuel inlet thread size is not a restriction ,its all in the needle and seat assembly
I used to think the same thing and in fact I made 530whp running it that way but the way I was explained this by Aeromotive was like this: running a -8 an line to a -6 fitting into the carb would increase head pressure at the regulator in high horsepower situation. What that means is, when you run a high pressure fuel pump at say 20 psi of boost, the car should see 26 psi at the needle and seat so that fuel doesnt back up into the line. If you add a restriction before fuel gets into your carb, you'll see 26 psi of fuel pressure, so the regulator will bypass the rest. After the restriction, depending on fuel pump, psi will drop. How much? It depends. But if its more than 2psi, you're in trouble.
Awesome vids .so sorry I jus started watching. I'm not making crazy power. Have the backs set up. I'm running a 4150 holley. Did the hangar 18 mods. But afrs are good cruising. But when the boost hits car always go lean. I am running a primary pv do I need to run a boosted one?
Simple stage recently restocked brpv. Hopefully, everyone that's going to do this buys one soon because scs says " they're too busy to make anymore at this moment"
If you're smart you'll get 2 😂
@NightWrencher lol I'll buy another when they're down to like 32 in stock
Do you think a 2bbl 351cfm autolite would be alright for a ford fe 360? Stock engine im just aiming for 6 or 7 psi. Cant find any information anywhere. Nothing fancy at all, just cheap parts slapped together
A 2bbl doesnt feed a 360 adequetly enough without boost. With boost its not going to get much better. A 350cfm 2bbl holley should have the throttle bores similar to the primaries of a 650 4bbl. It will take more time to spool the turbo and horsepower will be way down but it can be done relatively easy.
Do you do sidework I need my carburetor set up For my turbo it is a 750 on alcohol I can mail it to you
Hey man, I take on side work but only if its local to me. I do all the tuning on a chassis dyno so every set up is different. I would contact PRC carbs, CSU or C&S. They have much more experience doing tuning by mail.
I’ve always re-soldered and re-drill the set of jets my carburetor came with. They say it’s not good, but I’ve never spent a coin on new jets. For this weber they go in .1mm increments. Seems to work not too bad for me. 😅
The only reason its "bad" is because once you do that, you cant go by any jet number. They say that the holley jets flow more than their orfice size but it really doesnt matter. Need more flow? Drill it larger 😂
Yessir gotta let her eat lol
I think it has to be bad for it cause when they’re new their bore is as smooth as it can get. But from .4mm to 3.2mm sizes @ .1mm increments I have quite a bit of adjustability. What really helped my setup was that Daytona sensors ignition box
