Pondering a bit on the idea of multi-port injection on an Oz 2V head. Also pondering potential gains. It's totally apples and oranges, but I recently saw 30+ hp and ft-lb gains made in a 5.0L just by tuning the timing and injection curves.
General idea is a bank-fire set-up with 2 banks of 3 injectors. Which cylinders on which bank to be determined later. Timing would be handled via computer, with the dizzy advance locked down. This gives maximum tuneability (and complexity-*sigh*). Maybe a Mega Squirt & Mega jolt system, or some other means of computer management. Undecided.
What would be the best way to go about it on the mechanical side? I've had 2 different ideas on it-
1st- Use the stock Oz intake as my plenum, and put injector bungs in the intake manifold pointed at the intake valves.
or
2nd- Custom fab an intake with long runners (good for torque I hear) going up to a plenum box (looking similar to an Aussie X-flow EFI). It would require a plate to bolt onto the intake side of the head to house the injectors, and mounting for the runners. And some port matching. It also adds more places to develop a vacuum leak... unless I weld the runners on the injector housing and the plenum.
Throttle body would be the same for both. Mounting it would be more complicated on the Oz intake. TB mounting will be easier on the custom, since, well, it's custom, and I can fab a properly sized plate without needing to adapt it to an existing bolt pattern.
The first idea might be easier to execute, but I think the second idea might have a lot more potential. And it offers me more opportunity to mess up without ruining my only Oz intake.... If this succeeds, I doubt it will be on the first iteration.
Things at my disposal- Mill and lathe at work. Access to good welders to do my welding for me. Tubing bender that will handle up to 2.5" tubing. Delusions of grandeur.
Any thoughts on this idea? Any good books to go buy to increase my knowledge base? Am I daffed? (okay- yes- but is the idea daffed?)
Other thoughts include using this system, with a boost-refernced fuel pump, as a basis for a turbo set-up later. My hope is that I get the EFI done and quickly come back to my senses before it's too late. But the Dark Side of the Induction is strong.
