450-500hp injectors

[eddiee]

hey..what size of injectors will i need fore my s2 450-500hp project at 4bar. i heard 440cc will be god enough

[terrybullwon]

IIRC rule of thumb cc = Bhp

Just get the 630cc as they are big enough and no dearer to buy than the small ones. Also will allow you to go higher and not change injectors.

How high will 750allow then?

[audiman]

about 700bhp, but it all depends on pump pressure and pump flow rate.

Aron has some 750cc for sale. If you can find them cheap porsche orange tops would be ideal for your application but as Audiman says 630 cc would allow for future expansion.
I'm going with 750cc incase i upgrade to a gt35/40

What for Jamo?? I used the 630cc in mine with 10 bar pump and 4bar reg. Still had headroom and that was pushing a good 600bhp

2 reasons but mainly reason 1

1) Because I bought them cheaper than I could get 630cc ones

2) Aron is running the same engine setup and turbo I will have so it's a proven for my needs.
