DIY Blow Through Carburetor Build For The Budget Turbo Carbureted LS | Part 3 | Proform Race Series

This is the final part of the diy blow through carburetor series. In this video we will be going over how you can dial in the transition circuit on the secondary side of the carburetor. We will be going over the primary to secondary linkage as well as showing you where modifications need to be made on the new carburetor. We will also be recapping how to do basic tuning and I will offer guidance on what to do when you start to get everything together. This is the most important video by far but this series is just an intro course. Once you get the idea of what needs to be done, the real work can begin.

Recap from part 2:

Today we are diving into the second part of building a budget carburetor for turbocharging your own engine. In this video we will be getting deeper into the boost activated power valve or boost referenced power valve. Will will also be talking about the power valve restrictor channels in the metering block of the carburetor as well as the idle feel restrictors at the top of the metering block. The new carburetor that I am building is a 750 E85 race series carburetor by the guys over at @PROFORMParts

Recap from part 1:

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 soon.
