T04s v To4r

The only reason i ask i was under the impression 550\'s and 1600cc injectors supplied enough fuel for 500fwhp.
 
I was hoping for 400rwhp

More then enough for upto and over 500fwhp I would say going by how many high powered RX7\'s I\'ve seen are using this setup oh and 400whp should be easy as long as the engines ported :cool

It is enough for 500fwhp but your duty cycle would probably quite high

I can\'t remember what duty cycles are like for single running 550 pri and 1680 sec, as I haven\'t tuned a car with these injector setup for a while. But for instance the  last stock twins I tuned was in a ported engine, which also had upgreaded fuel pump wiring which makes quite a difference was at 92% duty cycle at 0.95 bar that had 369fwhp running 4x 850cc injectors if it had 2 x 550 and 2 x 1680 it would only supply 1000cc more. If you went from 369fwhp to 500fwhp you will probably find your duty cycles are up around the 90% mark again. Probably depends on fuel pump and fuel pressure you run as well.
