At long last... MFI!!!

After years of all this kicking around in my head, work has finally begun on the MFI system. I've been accumulating parts, documentation, knowledge, tools, and equipment to make this all happen (and work!) the system will consist of:

- 911"T" throttle bodies enlarged to 40mm throttle plates, tapered to 38mm at the head

- small port SC heads ported to 38mm intake port, machined for MFI injectors

- 911"T" plastic stacks taper bored to 38mm bottom exit

- 911"T" pump converted to RS pump specs and calibrated for the 3.2SS motor

This weekend I started to work on the machining for the throttle bodies. The tricky part is the taper from 40 to 38mm but I ground a tool to make it happen and it's working out:

There is a big difference between the "T" throttles and mine!! They are going to have to flow more than twice the air to support the 250Hp target.....
