injectors rated at 52bhp

[philip]

seem to remember the 172/cup injectors are rated 52bhp each. what does that mean in practice? they cant deliver enough fuel for an airmixture required for 55 bhp per injector? does that mean they just run out of fuel to inject and you start running lean???

are there readily available upgraded injectors? ben did you upgrade the injectors when running your 215 TB mod?

injectors were changed yes.

But at what pressure is that flow quoted, and what flow figure were you given?

Run out of fuel and you start running lean yes.

They are not special injectors so you can get higher flow ones that will fit fine.

i havent been quoted anything, Im just going from memory. reason Im asking is to understand what happens if you reach a theoretical 210bhp (4x52bhp) on the standard injectors? do you have to change them, do you up pressure? etc. etc.

 

[BenR]

i cant remember them either.

But if you run out of flow, you run out of flow, they are on 100% duty.

Id rather get higer flow injectors than up the pressure...unless you only want 211bhp lol
