I assume this question has been asked, and I assume there is a thread with a list of horsepower/injector size requirements... but I can't find it. Anyways, I have a built engine, a turbo good to about 500hp and Lovefab GT1 manifold, 3" dp etc... I current;y have 600cc injectors. Do I need more? How big? Thanks,
Jonathan

 

The RC Engineering website has a calculator to help you pick which size is right for you.

 

Here is the link: Injector Size Worksheet

A few questions about the worksheet...
1) What is the "Break specific fuel consumption desired? I read the note & entered .55, but do not understand the question.

2) What is the correct "System fuel pressure @ fuel rail?" The default value is set at 175. Anyone know the correct answer for an AP1?

3) What is % loss from Crankshaft horsepower to RWHP?


Thanks!

Use 43 psi for stock fuel pressure.

My calculated Drive train loss is about 12% give or take alittle.

BSFC is around .55.
