I had a chance to go out for a test drive this past weekend, and could not be
more pleased with the results. I still need to get the tune dialed in, and had things setup intentionally on the rich/conservative side, but did get on the throttle a bit. It pulled nicely - gave it 80% throttle and ran it up to 4400RPM. Indicated boost was 7PSI and rising. AFRs were in the mid 11's, and injector duty cycle was passing 85%, which is no surprise since I still have my 42#/hr units installed. Next order of business is to order up a set of suitable sized injectors. I'm leaning towards 80#/hr just to have plenty of margin. I like the ones sold by Ford Performance parts as they have full datasheets available, making them especially easy to calibrate. New in-tank fuel pump is also on the way - I settled on the TI Automotive F90000285, which ought to be plenty for my goals. More work to do, but very happy with the direction things are headed.

Super cool build! The V7 YSI is a fantastic supercharger. We ran one blow-thru on my friends Buick 455 for years.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
