Goodbye 18k RPM v8's: F1 is Officially going Turbo 4-banger!

No one has been innovative enough to find and implement a higher volume pump. It's not mazda's fault people are afraid of power. They could also just bypass that system all together and use regular injectors if they are only interested in power.

I thought it was the necessity of the high fuel pressure in direct injection systems (1000psi+) to overcome the cylinder pressures and to provide proper atomization, otherwise whatever is in the cylinder would be forced right back into the fuel system once the injector opened.

Correct.

I know cummins uses upwards of 30,000 psi on there common rail systems. At these fuel pressures, it is vital to keep any moisture out of the fuel. Since water is none condensable, it will blow the injector tip right off and wreak havok. A fuel/water seperator is mandatory. Maybe this is part of the problem with gasoline engines?
