That seems unnecessarily complicated but I can't put into words why. I get they'd need to be timed to the length of the manifold pathway. That "wind speed" would increase with rpm, ie: gets from injector to cylinder in less time.There's a whole section of the installation that is confusing enough that I'm leaving it to my tuner - the timing control.
I guess the basic gist is that you completely lock out the advance mechanisms in the distributor, set the magnetic trigger to around 50 crank degrees before the actual event, then use an offset distributor rotor and set it all somehow in the ECU.
It seems pretty complicated. I have all of the parts to do it, just no confidence that I can.
You also got regular distributor and rotor and spark timing still needs to advance somehow as revs increase.
Seems they could've just used spark timing (or a crank position sensor) as a trigger and set the injectors to fire some milliseconds before (probably where that 50 degrees comes from). Then that would be a parameter you could adjust on the little screen, tuning it from inside the car.
I didn't watch the entire video. I'm assuming they just used the 4 injectors to get enough fuel in there to make big power. They're too close together and too far away from the heads to do much good triggering them individually it seems like, maybe not.
Cool stuff anyways. Just trying to think of a simpler way for it to grab a point in time or point in rotation to use to time the injectors from. Maybe that would require a couple extra parts and wiring and they were trying to keep the overall kit as bolt-on/few individual parts as possible.
Can you program a couple different settings in it? Like one for lower power but more manageable for driving in heavy traffic, etc. and one for maximum fun.
Could trigger something like that off the TPS too. Would be akin to flooring it and opening the 4-barrels, lol.
