porsche orange injectors, part no 0280150791, anybody running them, would they b a good mod, cheers paul

That all depends on what kinda power you're looking to run

I have them in mine. Not sure on the part numbers though. Mine runs circa 440bhp cant remember the duty cycle but they are nowhere near their limit. In truth I could probably get away with RS2 injectors.

in www.ultimot.de can be found the schedule, which shows possibilities of several in Audi used injectors. Orange Porsche 911 (993 biturbo) injectors as well - ~ 510 cc at 4 bar.

I use them in my car at the moment, they can run up to just about 500 bhp.

Thanks guys, thats wat i need 2 know

Paul i am watching them to ...lol

As a rough guide to power capability of a set of injectors on our cars - the fuel flow rating in cc per minute at the appropriate fuel pressure indicates the maximum power you can expect to run. So a set of 500ccpm injectors will yield ~500bhp... Its just one of those fluky calculations on a five pot.

What you have to remember is injectors are almost always rated at 43.5psi (3bar) and so when running a different pressure (nominally 4bar on ABY) the injectors with flow even more fuel. If you search here or google for conversion calcs you will find them - its not a linear relationship.

Also remember that you have to derate the max power estimate by about 15-25 % to the point that you dont want duty cycle much higher than 85% and a few more percent for tolerance and aging cant hurt either.

Aha i aint the only 1 watching them, lol

[Audi Parts Guru]

I'm watching them too, lol

Game on

Take it there's a set on ebay? I have some RC 750cc to replace my Porsche ones, probably a bit of overkill but hey.

Hey jamo u sellin the porsche injectors then, would b intrested

Increase in flow is the square root of the pressure increase.
Example: if you increase pressure from 3 to 4 bar you increase flow by approx. 15%.

Sorry not for sale at this point as they have been promised to another forum member.
