Default Big MAF spray

Tried search but. How much can u spray through 85mm MAF one nozzle drilled .125? Looking for 250rwhp. Logged 13396hz at 483.12g/s on a .062 jet. I am on E85 and was not lean according to WB, which read .79 lambda or 7.74 AF. Trying to figure out max. Looking for more.

If you were at 7.74:1 a/f that's not good. have you compensated in your tune for the e85? what injectors? Dual .060s is about 240rwhp, and that equates to about a .088 single jet. Your .062 is about a 135rwhp shot.

OK, 483 g/s is pretty high of a load, and if your a/f is as rich as you claim, your dumping way to much fuel. Your not quite maxing the MAF (512g/s) but close. E85 is whole new ball game. Is it set-up n/a for e85. Your MAF is getting better than a good reading, to good for the e-85. I would get an HSW Interface and dial in the a/f, this will bring your g/s down also, and MAF freq. Hope this helps some. if not clear let me know and I will try again.

The tune for n/a is set up for the e85 and have no probs. EGTs are at 1077 na and 1120 on gas. Equivalent 14.7 A/F for e85 is 9.8. I was told my 7.74 is equivalent to 11.5 on regular fuel. Still learning this e85 stuff, but like so far. Takes longer to get to operating temp. So Robert, do you think I can spray an .088 jet without maxing. What would be max? Where do u think A/F should be? Thanks.
