Re: Supercharger

I've tried the boost gauge directly off the supercharger, where the small port that I assume runs to the fuel pump (that's where it does on mine, anyway), then finally on the rear of the carb, where there's a large port for additional vacuum supply. It's on the opposite end where the vacuum line for the brake booster is. Keep in mind I'm using a 600 CFM Edelbrock, which isn't exactly the same as the AFB you have on your Avanti. The gauge seems to work, as it move from 20 inches of vacuum at idle to 0 under load and almost full throttle.
