Injectors

Will 700cc injectors flow over 450bhp?

Im not 100% sure but i would think not and if they do then will be on limits

700cc @ 3bar @ 85% @ 0.5BSFC = 453bhp 
700cc @ 3bar @ 100% @ 0.5BSFC = 533bhp 

So according those figures it should then!

These are only guide lines i would say its not the best method running the injectors to the limits but im no expert ....

Using brake specific fuel consumption to guide injector size you would want 900cc for over 450hp & sensible duty cycle.
You could squeeze 700cc for 450hp but duty cycle would be high & also increased fuel pressure maybe needed.

What will standard injectors do ???

Max out 330 340 iirc mate ...

I'm looking at picking up some ID1000's. Just to confirm, using the standard rail do I need full length injectors with 11mm o-ring's?

I'm running 750cc I've been told they are fine for 450 bhp but above that they will be stressed

@gtir_woody
yes full length 11mm o-ring

Thanks mate

Around 330 johnny but got then just for future proofing the car as I want more POWWWWWER (as Jeremy Carlson says) lol

No probs thought they were quite big. I got 700 for the same reason although if i had money and time i would run smaller and up pressure on fuel for a better spray pattern
