I am just curious what other 840 owners are running as their operating temp. Just post them up
Do you run it in the sand or are you strictly track racing? Are you running with an external oil cooler? I have heard this may reduce the operating temp by as much as 30 degrees. This summer I want the 840 but I am concerned with overheating in the desert riding.I installed a racepak dash for my race teryx, I have 840 bbk with cams, 39fcr's etc. My race rig weighs 1600lbs. I can overheat it if I am not careful but normal operating temp is 200-210 degrees, stock radiator. Oil temperatures runs at about 240-260 degrees depending on load. Oil pressure runs from 20 at idle to 75 at WOT when water is at temperature.
I clicked on your link and no information was available for this kit on your site. What is the discounted cost for the complete kit?We keep seeing these high temps on the Teryx. So we became a distributor for PWR radiators........ We all know the Teryx runs VERY HOT even stock. Installation of his PWR radiator will lower engine temps dramatically.The stock radiator is a single pass radiator that is 30mm thick. This PWR radiator is a dual pass radiator that is 42mm thick and it will also hold almost 500cc more fluid then the stock radiator. This radiator is a direct bolt in replacement for the OEM radiator. This kit will come complete with A new oversized radiator, new high flowing fan and fan shroud. We will also have a complete PWR oil cooler kit in about 4 weeks.

That is one thing we tried to fix with our temp gauge kit. Once you install our temp gauge kit you can manually turn on the fan at any time. With the fan in the off position the fan will cycle as normal.You can actually find it in the manual. Thermostat opens at 185deg, fan switch is set for 203-208deg, warning light comes on at 232deg, give or take a few degrees on all of them.
Can you explain to us laymen how this will help? Also, Weller racing sells a billet high volume water pump impeller. Does anyone know if it works?If you need the stock rad to run cooler the take the water pump cover off and mill .050 off it to pump more coolant.
Do you happen to know if anyone has been using a high volume impeller and if so, do they help with the flow or pumping issue? Just a thought because I have seen an impeller on the Weller racing web site and I'm wondering if it works.DesertDog615, the impellor blade in the pump has too much clearance to the housing it sits in. In the normal condition (mainly at idle) there is too much static water pressure ahead of it so it can't push it and it cavitates (circulates itself in the pump because of the excess room between the impellor and the housing). Taking away that clearance will not allow the pump to cavitate thus pushing the water up hill better. This problem only occurs when radiators are much higher than the engine, plus the length of the lines are long so the pure volume of water gets heavier. Plus it doesn't help the pump is on the bottom of the engine. In any situation on these motors anytime your above 1500-2000rpm the problem goes away so don't worry its not that big of a deal. I only noticed it because my big motor would push the temp guage way up when i was just sitting idling it and the fan wasn't coming on.
I know your car is very built. So i figure you have done the testing and know what it is going to take to keep these things cool. We will be running a PWR radiator and PWR oil cooler on our 840 build too.180 to 200; have rad and oil cooler
