Slant 6 Turbo 68Dart Project
So what does the mod do and what's all entailed can u put it in lamens terms so I understand I also thought about propane but I think to much power would be lost going that way
Basically You're doing a few things:
1.Cutting the choke horn off - and removing the choke - then filling in the slot where the choke rod came through the base of the carb cover.
2. Putting in some kind of uncrushable float- usually nitrophyl to make sure boost doesn't crush it.
3. Removing the power valve and turning it into a boost referenced power valve, or one that opens when it has pressure.
4. Filling the vacuum port hole on the bottom of the carburetor.
5. Referencing the power valve pocket to boost. I drilled a 3/8" hole through the side of the carb, and put a piece of 3/8" tube from there to the carb hat where it receives positive pressure. You can also reference this port to your exhaust.
6. Jetting up to combat a lean AFR, which is done through a wideband setup. That is the first thing you will need when turbo-ing - a AFR reading.
7. Then there's the "Crutch" which is a VTE (vent tube extension) where you are putting a piece of tubing on top of the vent, and bending it towards the intake charge.
I used a Holley 350 to do all of mine.
