Thread: Dual Quad Sequential EFI

Mike, that's a good idea. I could probably fabricate something along those lines.

My idea was to fab some aluminum restrictor "plugs" that fit in the TB bores. The bores appear to be just straight holes with no venturi shape at all, which stands to reason. There's no need for a venturi if you're not trying to draw fuel. The plugs could be accessed easy to work out the restriction size.

I have only found one reference on the web to a similar setup. That was an article in Hot Rod (I think) about an LS powered Nova. The owner said he wished the power delivery was more progressive, because the throttle was kind of like an "on/off" switch, which made the car difficult to autoX. I've also heard the same thing said about regular LS intakes when very large TB's are used. The throttle response gets touchy. Apparently, port fuel injection with a dry intake isn't doesn't suffer from the throttle response problems that can sometimes happen with very large carbs.

I'm pretty excited about making this work (can you tell). These kinds of things are what makes hot rodding fun for me. Too bad I've still got a lot of work on the car before I get to really work on this.
