sad news... I finally hit the brick wall with injector size with e85... I ran out at about 365rwkw with Nismo 740cc injectors. Was trying to get it up to 390 - 400 but i could only manage 382rwkw with the mixtures leaning out to .87 at the top end of the dyno run.
I had to empty my tank and fill it with BP98 to get the power at a safe level that i wanted for power cruise - so unfortunatly i will not be running e85 at power cruise.. However i did get a reliable 380rwkw on pump 98 so we are good to go for power cruise.
I would have loved to be able to fly the e85 flag but that brick wall hurt. I was not keen to settle for 360rwkw on 100 duty cycle - I like my engine.
Yes i did check base pressure, there was no room for improvement, my base pressure was at 52psi - was not keen to raise it anymore.
