This is a funny one, hard to know what to think, but 600bhp id be shocked with TBH.
The AFM thing. Well, it would max out before then, but with the right electronic trickery you could fuel way past that, but itd be total guesswork and terrible fueling, ie the fuel at the max out point would need to be enough to fuel for 600bhp as the fueling will stay linear from then on.
The turbo on it sounds like it might be a cossie RS500 unit, so good for 550bhp at a push, and by a push i mean well over 2bar boost.
if you check cosworth`s they run green injectors and make 500bhp all day long
This maybe shows a bit of clever reasoning i didnt at first notice, or maybe the guy is just waffling shit...
I think maybe he is running WAY more fuel pressure than Skylines generally do. I can only guess this as i cant remember what skylines or cossies generally run, pressure wise.
Cossies are 4cyl.
4 green injectors are good for 350bhp, a little more at a push.
500bhp on greens is achieved with eight greens, up to about 550 IIRC.
Maybe he is trying to show some comparison? god knows...
Greens are 390cc.
390x8= 3120
550x6= 3300
Maybe he saying if you can do 500bhp+ on 8 greens you can easy do it on 6 550s as they are higher flowing overall even with 2 less.
Looks like fuel pressure is maybe the reason. Also gonna depend how rich etc you run the thing, efficiency etc.
Standard AFM, the turbo, etc etc etc is still mega questionable.
So basically, the seller needs to prove it or STFU :chuckle:
