2007 FLHTCU with a 2019 Roadsmith Trikes conversion. 2020 engine upgrade from 96 c.i. to the Screaming Eagle 110 c.i.
Living in South Florida, especially in the summer with 98* temps and 90% humidity, engine over-heating is always a concern. A typical day would see my oil temp north of 260* with very low oil pressure at stoplights.
When the 96c.i. engine finally failed and I elected to upgrade my motor, oil temp/viscosity was foremost in my mind. I had done my homework looking at jug coolers and true fan assisted oil heat exchangers. My decision to go with an oil H.E. with the retrofit oil filter was well advised by several Harley mechs.
I installed the 3.0 and must say it is as advertised. My first ride was mid-day in 88*/60% and try as I might, the oil temp never went above 230* and while moving settled around 210*. The best part is that while sitting at a red light, my oil pressure was 26 psi at idle. And, getting the oil out there into the slipstream is quite advantageous.
I am extremely happy to recommend the UltraCool 3.0 to any Big Twin owner. The folks at PC Racing/UltraCool were patient in answering my questions, are technologically savy and were a delight to work with.
