The hottest???

This question intended mainly for those who have experimented with CHT's .....
Which cylinder runs the hottest on a 911?

I will be installing my CHT soon. Following the KISS rule, I will only have one gauge and one sender, so want to have it reading the hottest of the hot. Which one would that be?

The knock sensor on my 3.6 is located in the head for cylinder #3 if that means anything.

Almost certainly the one that is most difficult to get to.

The 3.6 knock sensor is comprised of a tuning bar and a sensor across the entire bank of cylinders, one per side. What you're talking about is the cylinder head temperature sensor on #3.

My guess would be front, left side piston as the air from the fan blows in the other direction and the forward cylinders are usually hottest.

I will guess 3 and 6 or possibly 2 and 5 but, I would never rule out 1 and 4.

Well, cylinder #1 is cute in a Maryanne from Gilligan's Island sorta way.
#2 is totally girl next door. #'s 4,5, and 6 have been beaten with the ugly stick.

Yeah, definitely cylinder #3 is totally HOT!!!!

heh-heh .. .but your still right. The 911 cyls are numbered so that the #3 is left of the flywheel; just lke the 4-banger.

It's also the one furthest away from Dougs cool-collar . . .so it must be the hottest.

of course Dougs cool-collar is on a shelf somewhere in california.
