Much like backcountry riding often goes. The path to this build is much the same. Never planned to go this far. When you approach the point of no return you either focus on exit or hold it to the wood. My initial purchase was a 16 viper to be set up @ 270hp MCX kit. Carrillo rods, titanium springs, valves, head shims/gasket, rear skid, 2 hyvo chains and a chain case, another head shim/gasket and stuck valve and I managed to get 1400 miles on the sled. Issue I continued to have was charge air temps causing detonation. Air to Air intercooler was more of a highly efficient heater most likely due to the conditions I ride in. If I were to plan a build ahead of time I would use a sidewinder and save a lot of the hassle. So my dilemma was do I build my own water to air intcooler set up and install in my Viper or...... Put it all in one of my Axys chassis. No comparison to me in handling between the two. That part was easy to decide. Hard part was sacrificing a Perfectly sound sled for a what if..... Well I managed to stick a ring in one of my other turbo sleds and it made my decision. pulled the stocker with 300 miles and put it back in ops and had a vacancy for the next implant. Since starting the build I relocated for work and put the project on the back burner. Before I left MT I managed to take it out on the snow a few times for some short test runs. Now Im finishing up some fit and finish work to hopefully get it out before the snow is gone this season. My delay has been wanting to use nytro or apex oil tanks or build my own. Decided to just build it so i could locate in the best spot not just where it fit. Foaming is an issue with a way to return oil without causing more airation as well as ridding what is. Feel pretty confident in what I have created so far and hopefully it works as planned. Plan to weigh sled before I head out in a week to see what it does. Im guessing 460. hoping for less.

WoW. AMAZING!! I love it. I wish I could see it in person, but the pictures help with that. There is a lot of hours put into that, especially that oil tank. I had not heard of people ceramic coating things their self, I will try that on my next build. If you can please put that thing on the scale. Not that it will matter as it will be lighter than the viper and the weight will be more centralized. By the looks of things their is not much room left on the turbo side. That must be why you had to make your own tank.

Thanks! Its definitely been a time consumer. More on placement of everything then the actual effort. I didn't want to deal with oil tank in front of quick drive. moving forward seemed best. I'm doing everything I can to keep air flow open throughout sled. Main reason on cerakote was how close to turbo tank would be. I removed coating on panel vent side to help cool oil. Running Helium hood and I routed intake through access panel. My thoughts are to check charge air temps with stack and then run in the nose of the sled under hood. Running water to air intercooler I don't expect to see a huge change. Typical charge temps were 64° on other setups. If I'm within a few degrees I will keep it under Hood. I get tired of dealing with powder sticking to Snorkel screen and killing air as well as Branches trying to tear things off. Moving skid to the right location created an issue with rear rails. Had plenty of forward so I removed excess rather then buying new rails. Always hated filling intercooler so I built a reservoir to fill with sight glass for quick check. Key is putting a smaller hole in center of vertical section so air is not allowed to re enter system after it rises into neck. I fired it up a few days ago and Im going over everything one more time before I try and take it out. Ran out of time on last trip. Hopefully here in the next few weeks before snow is gone.
