WTB injectors S-afc

Tittle says it all. Im looking to some fuel upgrades for a incoming evo 16g. injectors i guess around 580-680. and a s-afc 2. also a walboro 190 would be good but i can pick that up for cheap. Thanks

If you are only going to be on the evo III, I would get 550's. They'll support ~420 hp, thats more than you'll get to on that turbo.

gonna have to disagree and say the 550's can't flow THAT much, not on stock fuel pressure anyway. Since you're still on a safc then 550's will work best, timing advance is too much over 550cc's, you just won't be able to run high boost. like 20+ without leaning out.

Really? This is the formula I was using:

injector cc X .1902 X # of cylinders = max horsepower (X inj duty %)

That would put the 550's at 100% IDC at 418 hp and some change. Cant argue whith experience though, who knows whos ass that formula came from.

the formula is correct, however, IDC's should never be close to 100%. Plus it all depends on the afr he wants, I doubt that formula allows for a safe tune. Plus when I talk hp numbers it is strictly whp numbers, not sure if that's what you meant.

Ahhhhhh, gotcha.

so i guess my estimate was somewhat right with injectors. 650's approx

what does the ".1902" mean?
