CJM 370z Fuel System Products: A Brief Overview.

I have not tried pushing the stock feed line so far but I have heard of several cars on gasoline dropping fuel pressure before making it to the power I have.

With a low compression built motor I would tone down the rating 25-50 HP. Pump limited before injector. The 1000s should be good for about 625-650rw in a low comp motor, and close to 675-700 high comp if you have the pump for it.

You know what, it's so hard to put ratings on the stuff... People in the Z world often consult with me when they run out of fuel and want to talk about where to improve it. When I take all the results and feedback I have seen from various cars, there is ridiculously low consistency in results, making it so hard to rate a setup, or even a pump or injectors. I should probably start compiling a fuel system performance database so people can see what has been done with different configurations.. Specifically for the VQ which offen seems to outperform other engines in terms of efficiently using the provided quantity of fuel.
