Default MEFI 4.. How much HP??

I will be converting my Procharged ...carbed to MEFI over the winter.
I am in Michigan and the water temp can be 72 one day.... get a offshore breeze next day 48 degrees, drive-ability sucks.

MEFI uses hi impedance injectors, only available up to 80 pounds. I am at 1100hp now, this should be doable
w/ 80's (http://www.rceng.com/technical.aspxl). But is any one building crazy hp w/MEFI? and what are they using for injectors?

Randy

It was good talking with you CNC. The (8) -80's will do all that you need. Good luck and let me know if I can help.

Bosch makes a 95lb Hi-z injector:
http://www.fuelinjectorconnection.co...&productId=214
and they are around now for 600$ a set. Only drawback is they use a ev-6 connector whearas your Mefi harness uses ev-1. There are adapters though fairly cheap.
As far as power, you can drive 10 injectors and there are custom 200lb hi-z injectors so theoretically you could support 3400 hp at 85% duty cycle on the injectors , Smitty

MEFI will support up to 12 injectors, MEFI 4 will also support Peak/hold injectors or low impedence

You could also run a piggyback injector driver to run whatever and how ever many injectors you want.
