Direct port injection

[Brad]

If you are going for that much power your original idea of one nozzle per cylinder make since. The flow will be very high at high rpm and boost. Use only distilled water and methanol if you need to keep it from freezing. Just pring it on a little late and have an over capacity pump. Set up a kit for a quater mile 4 cylinder using two 0.9mm nozzles per running. The car runs on gas and 42psi boost for seven seconds or so at a time.
You could use one nozzle per runner for high boost and a variable flow at the inlet for the less than full power improvement.
There are so many combinations when you know the goal.
