Two Questions - Injectors And Intercooler

[Ronin 09]

Searched and read about 8 pages of info last night, but didn't find anything that was really definitive.

I want to know what the upper limit in rwkW for

- R32GTR intercooler

- R32GTR injectors

Thanks in advance

it will be hard to get an exact answer as there are so many variables.

i have reached 100% duty on my injectors running 253rwkw BUT the tune is very rich, so a leaner tune should equal more power, and less duty (to a point). i wouldnt want to push them past 280-290rwkw personally.

intercooler is a tricky one too, but i reckon it's good for 350rwkw. that's just a figure i pulled out of my arse.

thanks rich... what else do you keep up your arse....?

do you think that if you were to up the fuel pressure the injectors could do a bit more?

Leave them std...that way you wont have more power then my car

[Beer Baron]

i guess you can get a little more flow with using a reg to bump up pressure, but i'm not a big fan. as it puts more stress on the fuel lines under pressure, and can cause poor injector spray and sometimes leaks. far better to go bigger injectors if you need to. you are running PFC i think from memory, so i would go a set of the 700 sard. they bolt straight in (just get some new o-rings) and are easy to tune with the PFC. they are not very expensive either.

Injectors, at standard pressure, around 265 rwkw (same as the fuel pump)

Intercooler, 300 rwkw no problems

hmmm injectors it is

i want to be a tight arse.

Cool I was'nt sure what the max of the R32 injector limit was either

cheers

Roymeister,

What duty cycle did you run at the usual power level and the 250rwkw or whatever it was?

[West]

I also ran 250kw@rear with injectors duty cycle stated max 82%. That's RacePace's tune by the way.

[Ronin 09]

rich - reckon those sard 700ccs are the go... and maybe a slightly bigger cooler... i like the look of those ARE aussie coolers
