I subscribe to Hot Rod magazine and the latest issue has a huge article on electronic fuel injection (EFI) for aftermarket applications. Everything from Weber “lookalike” EFI to a carb application from Retrotek. I am extremely interested in the carb offering from Retrotek. Looks very similar to a Demon carb and the installation is very simple. Full closed loop system without the need for a fuel return line. I want to “blow” through this carb with a Paxton supercharger. Tuning an engine with a normal carb to run with a supercharger is tedious at best. Dyno is the best way to go, but a normal carb will never meet the efficiency of modern fuel injection.

The article in Hot Rod tests the Retrotek system on a 67 Ranchero with a 351 Windsor engine and C4 automatic. Modest increases were gained in HP and torque, but drivability and mileage was significantly increased. The system self learns itself as you drive. When coupled with an MSD, EFI compatible, distributor even more increases occur. They installed this EFI in 5 hours including a lunch break!
I plan to purchase the EFI first and do a comparison with the 302 in my GT/CS. First without the supercharger and then with. Mostly for mileage. I get 13 MPG around town now. This is with a Holley Street Avenger 670 CFM that is more about power than economy.
Time for this old dinosaur to step up his Mustang to the modern world of EFI. It will burn $2k and take a long time if never to reach payback. But the power and drivability should be awesome. Finally an easy to install self leaning EFI system.
