I just put a digital temperature gauge on my sled, and took it out today, 10 degrees Farenheit, fresh powder on the trails, and I was consistently running from 161 to 183 degrees. That seems kind of high to me, compared to others, non-Vipers, that I was riding with. They were getting readings on their sleds(Polaris,AC) in the 130's-140's. Even in Powder over my foot boards, It wasn't dropping below 160. I do have a rear heat exchanger, Opticool gasket, and SLP Triple Pipes. Do the pipes make you run hotter?
I was just curious what range I should expect when riding. Just idling I was around 158-161. Any input would be great.

I have an Auto-meter full sweep gauge on my Viper engine is stock with V-Force 3
reeds and a rear cooler and it runs right around there . 150 to 180 depends on the trail conditions and how hard I am on the throttle . Hope this helps .

Vipers temp light comes on @ 194-230F so you were getting on the warm side,how strong you got your coolant?
the pipes are probably whats huring ya working the engine harder,you running high rpms'(clutching)crusing?

I have been running full strength anti-freeze. Maybe I should be cutting it down. RPM's off the top of my head I don't know, but cruising from 30-60mph, 1/4 -less than half throttle. 21/40 gearing with 8 inch drivers, 136" track, clutching from Hartman Inc. The faster I went temperatures rose of course. I have a Peak Performance Head w/ 22cc head inserts. I have the sensor screwed into a port, that is pre-tapped on the head, right by the 1" hose that connects to the head. Is that port/hose area flow output from the engine, or input to the engine, just curious if that is the hottest temperature source of the coolant.

i would cut back to 50/50,i think that peak head cools better then the stocker? yes that should be the hot out put for coolant where you got the senser. the 136 and mods is probably working the sled little harder,just02ViperMody44 said:
keep an eye on temps..
