Calculate what size injectors you should be using for the power you're running.

Thanks goes to Meddy, who found it originally.

As it refers to crankshaft HP, I'm assuming that's the same as the fly figure. Makes it a bit difficult to work it out for you rwKW people.

According to the calculation, I should be running 640s and the stock JDM Spec R is already maxxed.

hopefully that's based on normal injectors and not the c*** that RC sell :P

bad experience on my Z and a number of other Zs with them... very inconsistent flow rates across a set.. :(

at idle it's about 35psi... but it will increase as boost pressure increases I think 40-43 would be a good number?
