Hi,
do anyone know what is the max safe awhp that the 560cc stock injector can cater?

Thanks

 

350whp on a dynapack dyno.
Probably around 340-360 on a Dynojet.

 

Thank you RS Mike...

Sad to say im still not sure whether my current Sard 850cc injector scaling & latency value is correct.
So far hv tried few different scale & latency but here is the value (943cc scale - 6.12 / 3.12 / 1.992 / 1.320 / 0.888 / 0.672 / 0.408) which is closes to 14.7AFR during idling compare to others scale & latency value.

But now ive 2 things to worry about :
1) Stalling issues as AFR will deep til 10AFR whenever throttle lift off especially A/C on
2) AFR doesnt goes below 11 or 11.5AFR while WOT or High Speed Run til Redline....

Other than that car, runs fine or is it got anything to do with advancing the GSC S2 cams? No driverbility issue other than improved on lower end response.

 

I'm making 374 whp on stock injectors and fuel pump.
Virtual dyno with Dynojet setting.

 

I have observed 375-380 on our dynojet. It does vary though which doesnt entirely make sense but a stock cam car maxxes out sooner than a cammed car.

 

I did 404 @ wheels on a Dyno jet but the idc was at 98% if you run a non dangerous idc it will be right around what John Bradley just said.

 

I've done 330hp on a Mustang Dyno with stock injectors.

 

I make 402hp on the virtual dyno, but I run alcohol injection which gives me alot of extra fuel. I think my injector duty cycle is only 83% if I recall.

I guess the point is.... it is totally going to depend on your fuel and other mods. The better fuel you run, the leaner you can run, and thus the more hp you can get out of smaller injectors.

 

Yep, that's what I'm at too.
