Seeing some evidence of some special CIS Bosch R-Sport injectors when looking around.

We should not be afraid of fuel pressure. There are Bosch fuel pressure regs to 8 bar and fuel pumps that support up to 8 bar. MFI runs in the 230 PSI range. We just need the the pumps to keep up.

I suspect there is some weaknesses to the math formulas that predict how much HP can be supported by a give quantity.

First, we run turbo 10% or more richer than a N/A motor for cooling.

Secondly, we are usally injecting fuel under boost into a higher pressure environment which will reduce flow.

Thus, we might need to reduce the HP level potential by as much as 20% I would guess.

Some more goodies:


* 500cc per minute is approximately equal to 49lbs per hour which is equal to approximately 100hp.

* lbs/hour = cc per minute / 10.2

* lbs per hour = HP / 2.04

* cc per minute = lbs per hour x 10.2

* cc per minute = HP x 5

* HP = cc per minute / 5

* HP = lbs per hour x 2.04
