I havent found anybody trying to do direct port injection so i figured why not give it a try.
I work solo in my shop and have so much going on its not funny plus trying to build a house at the same time.
Once i get all my parts for the truck ill take a week off and throw it together and start testing.
Ive got several customers running M1 and ive always been impressed with that stuff.
Years ago i ran -30* WWF in my turbo truck and never used it to depend on it but for towing trying to keep everything cool. WHen i took the heads off that engine the intake runners, valves, and pistons looked brand new.

So what is the goal for this setup? Intake charge cooling, supplemental fuel or combination of both?
I recall a discussion about nozzle placement years ago and the consensus was the closer to the valve the injection was, the less time the alcohol was in suspension to cool the air charge. Having methanol injected into each intake port would give very little time to cool the charge other than in the combustion chamber. However, the cylinder distribution would be much better.
Controlling with the Dominator, would you pulse the injectors per intake cycle or just trigger them 100% based on rpm/kpa/tps? My concern with not pulsing would be pooling on the intake valve.

I ordered several more Devils Own nozzles to test with and a Holley 1000cc/min Solenoid/Nozzle deal.
My next research will be what pump for the nozzles. And then ill have to figure out what to use for the Port injection pump.

This poor lil 5.3 is going to get its guts beat out of it testing all this stuff.
