Recommendation sizing and positioning

[Lancebin]

Hello,

I would like to hear your suggestions on nozzle sizing for my setup. I am running a rotrex C38-71 on my 1.8L 2zzge engine on e85 with ID1000 injectors nearly maxed out at 0.82 lambda. Currently making around 360hp conservatively at 17psi. I plan on running eventually e85 + 50:50 water/meth with the addition of an hsf3 kit.

Also, I am installing the nozzle(s) after the intercooler. Where would be the best location to mount the nozzle? After the IC outlet I have 2 90 degree bends going to the butterfly. But prior to the butterfly i have a straight piping of about 13" before the first 90 degree bend.

With a 50:50 mix would it be dangerous for the blowoff valve and wastegate (for boost control) to be venting into the engine bay?

Thank you.
