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?

Number 3 of course!!! Oh wait, you 911 guys have 2 extra cyls don't you...

I have been told cylinder #1 runs the hottest... let the debate begin.

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

masraum 03-25-2003 08:36 AM
hmm, I thought the knock sensor was on a bridge that covered and entire side?

Well, to fix that, just install a doghouse fan shroud... LOL

Later,
Tom

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.

Milu 03-25-2003 12:59 PM
At a guess three and five.

Jbabic 03-25-2003 03:20 PM
touch each one and tell us which one hurt the most.......ok, Im done with the sarcasism....doesn't Bruce A. know?

SteveF_911 03-25-2003 06:26 PM
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!!!!

RoninLB 03-25-2003 09:02 PM
I run a probe on 2 & 5

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 :D . . .so it must be the hottest. ;)

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

I guess Master Cylinder and Slave Cylinder don't count?
