Icdedppls non intercooled 1071 making around 8 lbs of boost on his 540s, has around 135-140* intake temps iirc. It didnt seem to change much if any going from 6 to 8 psi.

My intercooled B&M 420s, are in the 105-115 range with 8-9psi. My boat takes a while to plane off. I can see the intake temps climb to 140-150, then as the boat lays over, and begins moving water thru the intercooler, the temp drops 30 degrees very quickly. I was always skeptical about intercoolers, as I had never found anyone doing any temp readings in the intake manifold. After installing them, I can say that they do in fact do their job.

I would love to see some intake temps with a 177 or 250 blower setup. It be interesting to compare.
