Message: [QUOTE="akf250, post: 1533898, member: 2655"] [b]Trucks Alive![/b] Welp after the oil pump incident I ran into another issue. Trucks oil cooler became clogged after the build. Must of been junk in the radiator/block that ran through and finished her off. The big diesel event Prowl 4 Power is next week and I did not have the place, the sanity, or the time to pull the cab again. So I did my research and through down on a beautiful but spendy external oil cooler kit from ********** Performance Research. Install was going good until I broke off the bolt in the lower coolant port :doh: After getting that resolved and fighting with the fender well a little I got it all back together and my oil temps are perfect! [ATTACH=full]177629[/ATTACH] Truck runs great, the ride is better with the suspension upgrades, and is way way more responsive now with the cam, intake, and exhaust upgrades BUT....of course there is always a BUT....I cannot get more boost out of the Tow Power Jrs than 20 PSI. Does anyone know what boost level I should be hitting with stock fuel and a Tow Power Jr turbo? The main supporting mods that factor in are: KDD O-Ringed heads Stage 2 Cam O-Dawg Intake RCD Up-Pipes & Wastegate Kit RCD Manifolds No Limit Intake Plenum No Limit Filter No Limit Hot and Cold Side Pipe ******* 275 Race Tune I got my wastegate tightened all the way down, at least as far as I can tell. Is it just so efficient that it only takes 20 LBS to flow the same as a stock turbo at 55 LBS of boost? Bad wastegate? Wastegate controller? I know these turbos are good for dual fuelers and bigger sticks up to 800+ horsepower, I imagined it would have a higher boost range and I suspect it is something to do with the wastegate controller or a failed wastegate. Thoughts? Any diagrams of routing so I can ensure everything is hooked up correctly. I am pulling boost reference from the O-Dawg intake [ATTACH=full]177630[/ATTACH] [/QUOTE]
