Would 550cc Injectors give me 400bhp

Whats the spec on the turbo? Exact ARs etc...
550s can make over 450bhp if you wring the neck out of them... but you'd be better off with 720s

387bhp on standard injectors???? mine are maxing out at 1.2bar @ 6250rpm and the car made 318.9bhp on the rollers.

I don't think that there's any way that standard injectors could make a proper 387bhp :shock: :shock: :der: , Mine hit 97% duty at 311 bhp and 1.2 bar :? :? :? .
Running 4 bar fuel pressure and a 100% duty they could just about get there, But I wouldn't of thought that was the case with yours :?

And who's magic rollers where those two reading's taken on :? :? .
We all know that most tuner's will "make sure" you get the best out of your cars on the rollers, I was chatting to the bloke at wallace tonight and he said he could of given me another 10-20bhp if I wanted on the print out :shock: , I asked him if it was real power and he said no :doh: , So why would I want it then :der: I'd only be cheating myself I said :roll: .

And at 3 bar fuel pressure they could only make 338bhp at 100% duty or there abouts.
My own car got 20 bhp more by just taking it to a different tuner to be rollered, But I believe the lower Wallace performance fig myself of 399.6 bhp.

Here here!! My R went to Gordon @ Street Racers in Leicestershire for it to be put on the rollers and he too said that some tuners can make your bhp figure look better.

Still waiting on some shims!
387 on standard injectors isn't going to happen... After lifting off the throttle on the dyno run the operator just needs to use the brakes to fiddle the drag which will increase your Flywheel Power calculation...
To define what power you will hit at a given boost level you need to give us the spec of your turbo....

id go for 700cc's to achieve 400bhp at a decent duty; plus that then gives you the ability to go for more power without the need to buy new ones. Haven't read your car spec but you'll need an ecu upgrade (emanage/powerfc etc) to be able to run them.
I wouldn't bother using an air flow converter (such as a SAFC-II) as they dont provide enough flexibility to use the 700cc's properly (mine didnt anyhow). I think the SAFC-II can only handle +50% in a size change to standard injectors - which the 700cc's are not

So how come Jason Gant uses a SAFC 1?and has no issues?Simmo said:id go for 700cc's to achieve 400bhp at a decent duty; plus that then gives you the ability to go for more power without the need to buy new ones.

Most tuners I know dont use more than 550s with an SAFCII / Z32 AFM
