The little control switch I have for my methanol/water injection kit can be set from 1-25psi. What do yall recommend? I would figure the lowest setting so when it reads 1 pound of boost it is shooting the mist to it to help the IAT stay cooler. The guy I bought it from said he kept it at 5psi though, but my thought would be the heat would already be building up by then. I have hooked up my scanner and looked at the IAT while driving, and with the HE system while driving it stays at about 118-120 degrees F, but if I get on it a bit it jumps up pretty quick. Just wanted yalls opinion on the matter.

you have to find the sweet spot.

is this on a supercharger setup?

Mine comes on around 2psi.

Make sure to wire it to a power switch.

Yea, its for the M62 I have on my L61. Its already mounted, wired up and all that good stuff. Going to get the methanol this morning, and mixing it 50/50 with distilled water.
