If I'm gonna add a nitrous (Zex) and just keep my drop-in K&N air filter (or use a cone air filter), would that change the effectiveness of the higher pressure fpr (could it then go lean at WOT due to the air efficiency mods) or would it just use more of the fuel delivery without depleting it?
Also, my bro-in-law who is an airplane mechanic by trade and an experienced engine mechanic (boats,cars) tells me that the fpr mod can't work because the engine will compensate for increased fuel pressure at the injector by shortening the pulse. Is that true at WOT where we want the added fuel, or will the "out of the loop" WOT condition allow the added fuel pressure to put more fuel in the mix without computer or air/fuel system controls?
THANKS FOR YOUR HELP AND CREATIVITY!!
P.S. I bot a 22670AA240 for $78 (incl. S/H) from SubaruParts.com.
Just waiting to get these questions answered, then install!
