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

I'll start saving for a set of 4 1500cc injecters :thumbs:

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

They say its industry standard.

Why do you say they're cr@p?

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

"System fuel pressure @ fuel rail", what should this figure be??

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