Nozzle size

[rotrex]

I would have tried to centre them as much as possible in line with the fuel injector. Alternativeley consider adding a second set of jets on the opposite site of the fuel injector.
But I see your reasoning as a compromise had to be made due to space constriction and the curvation of the runners prohibiting going back much further.

Spraying like this will IMHO likely lead to less than ideal in cylinder distribution. Most spray will pass through one inlet valve only at least during the time the valve is open. Some spray will accumulate in the port while the inlet valves are closed. But there is reason the fuel injector sits in the middle, equal distribution.


I am looking forward to reading about how it performs. If you’re not happy with the knock supression, you can always add a second set on the other side and get a more ideal distribution.
Jet size might have to be adjusted, of course. Or boost increased.... :-)


PS. If the plenum is still off, you could prep for this two sided install by installing just the threaded bungs and plug them. This would safe the effort of having to remove the inlet again in case you would need the second set.

I am expecting to see big numbers from this build.

I’m trying to figure out which one is the negative on the Injectors and I have no idea how to find out. All six injectors share one wire and the second wire is a different color on every injector. So I’m not sure of the common wire is the ground and the ECU supplies power to control IDC, or if the shared wire is power and they are grounded by the EUC to control IDC. Any idea?

Shared wire is 12v
and the individual ones are grounded by the ECU mate.

Thanks!
Does that mean I can connect the -ve wire on the kit to ECU directly?
