It seems to work well an maintain an ECT of about 170 degrees as designed. I need to put it to the real test on some fast wide open areas in extreme cold but I see no reason for it not to function as expected.
If anyone is interested here is the place I got it. http://www.epicincor...y=11&ItemKey=15
Its expensive and designed for shifter kart racing. The only problems are the sales license is expired for the website and I took the last one he had in stock. If anyone wants one they can call the number on the website, Erik seems like a very nice guy to deal with and was helpful to me. Or PM me and Ill call him and if enough are interested he may put in an order. Its off-season so I don't know fior sure.
Kit comes with bypass t-stat and housing, hose clamps (too large but usable), and a 3/4 in tee (too large scraped it for a 5/8) Its bigger and heavier than it looks.
Ok here's some pics
Heres the unit, its anodized aluminum very nice quality
Here's where it needs to go, its a tight fit and my radiator is bent back about a 1/2 in so I had even less room
Here I mocked it up with some 3/4" heater hose from head to raditator and 5/8" heater hose tee'd into the return hose.
Now that I got my final hose lenghts figured out its ready for permanent install. I used gates heater hose for everything expect for the 90 degree at the water pump. There I cut the factory hose. I also wet sanded the white lettering off the hoses so it will look a little better.
I let coolant temp reach 180 then turned a fan on the radiator and the temp droped and maintained at about 170
The way this works is: Hot coolant from head enters housing. If its temp is below 170 degrees it goes down to the water pump and bypasses the radiators. At 150 to 170 degrees the thermostat opens partially and allows blended flow through the radiators and bypass. At 170 degrees its fully open and full flow is going through radiators. This can be installed year round with no issues. Thanks for lookin!
