Anyone have experience with the 13.1 head around Edmonton? Any detonation with straight 91 non ethanol?

I was on the PAR web site. In the description it says the 13.1 is 3000-6000 feet, but in the pull down it says 2000-5000 feet. :confused: Edmonton and area is about 2200 feet I think.

Lots of info on some older posts. Search PAR or scoll through the Polaris Pro section

Nice...... how was the install.

Fine.... just forgot to torque the DET sensor - so went by feel. I think it called for 16 - 20 ft/lbs but can't get my t-wrench on it.
Pulled both sides @ 100 psi (cold) with stock head & 120 psi (cold) with 13.1 head

I got 118-120 on my 2011. 1800 miles.
I think your motor is wore out. It should be higher . How many miles on your sled.

Could be just the compression tester i have one that reads 20 psi lower than the other I haven't check my 2012 yet but will tonight. 100 is super low in my opinion also.

Check mine tonight 125 on both sides sled has 350 miles on it

Motor's worn out !? - LOL. Rings may be a bit - motor is fine. The old war horse has 3100 km and still has x-hatching in cylinder walls on both jugs. And, it is a cheap azz comp-gauge. Crappy tire iirc.

In my case.... I hope it's a bad gauge :pray2: I will have to borrow and double check it.
Mines has been bouncing around a tool box for the last few years, so hopefully I will get a few digits higher.
