I made 260kw at 15psi so never 100% injector duty.

Injector duty is around 88-92%.(depends on AFR)

Does someone want to explain to me how thats possible?

Im making 290rwkw with 500cc and it 77% duty...

going by the above statement I could run E85 on my 500cc injectors and get more power... wtf...

PLEASE don't!

please do!

it's not possible under normal circumstances. unless your running wmi or something similar anything more than ~200rwkw on standard injectors is either running lean or is just a happy dyno.

Happy by 60 rwkw?

Standard injectors are 370cc, which i've been told makes them good for 370 crank HP at 100% duty and standard pressure, or there abouts? So in theory, the 400-450 crank HP Toshi is making would need %15-%25 more pressure to keep them below %90 duty?

Is that right, or am I missing something? Also interested in this.

Defently not the dyno, it reads within 3kw of factory spec on new cars that have been run up, maybe ive just got a freak 25? oh btw my vvt isnt connected =/ but that only affects mid =)

So a 220kw car reads 217rwkws?

[51NNA]

correct its also a dyno dynamics, my tune was done at 11pm on a winters night so it was getting nice freezing air, doubt it would make the same power in summer.

So the dyno is converting rear wheel power to flywheel

Explains a lot

[51NNA]

no...were did you get that idea from? LOL there is a setting that shows flywheel power but its defently RWKW, i dont understand why you think its so hard for a rb25 too make 200rwkw, my rb20 stock on 1bar was making 180RWKW...

I think he is saying factory specs arnt at the wheel they are the HP output at the flywheel

[51NNA]

Youll find most will say HP and RWHP these days, the tests were done on stock WRX's, when i worked there we mainly did wrx's because of the AWD dyno..and most of the time people would complain our dyno showed a low reading compared too others.

So, you pulled the engine out, put it on an engine dyno, the re-fitted it to the car and put it on the chassis dyno?
