Triton, I mean no disrespect when I say these things. But when you make a statement like "I thought the motor could handle a little more" it really shows how little you understand our Cummins engine. It can handle more.. alot more. The problem is, the stock turbo is basically a choke point. It's made to handle the power the factory designed into the whole system and maybe a bit more. And when you try to jam 200-300hp more down it's throat, temps get WAY outta hand. When you said you were at 1600+ degrees way before the end of the quarter, you answered your own questions. I don't care what guys say about you can go 1600 for 5 seconds or whatever. You're playing with fire if you do. My guess is you went way over 1600degrees. Plus your drive pressures were crazy high probably double what your boost was. Whoever gave you the advice to just mat the throttle with the TST and Smarty and your stock turbo doesn't know his ass from a hole in the ground. PERIOD. I hope you get it all fixed relatively easily. Hope there is no block damage. I feel for you. It can happen to anyone, but someone gave you really bad advice.triton said:Well guys... I think the worse that could happen, has.... I don't know for sure though so you tell me please.
Got the new turbo and manifold installed. Completely took apart the exhaust and clean it a good as I could. Drained the oil and changed the filter. The moment of truth.... I crank it up and it runs.
Unfortunately, the oil continues to drain out of the exhaust. The truck runs with a very ruff idle and actually sounds like one of the sled pullers with a lugging turbo. I don't believe my 64/14 will do that...?
I let it run for a while hoping the oil will stop draining but, after 5 minutes it continued.
When I was running it, I idled up and got the turbo spooled. Once it was spooled the rough running idle cleaned up and it seemed ready to rock. Back to idle though it runs rough.
The smoke only looks white and there still a lot of it. My Smarty is telling me cylinder #4 is misfiring... obviously full of oil.
If you don't mind.... what is my next step ? Do these motors have sleeved cylinders ? Did I fry a piston ring and oil is blowing by it ? I'm really shocked at this since most of you guys are running a ton more HP than me. I figured the motor could handle a little more than what I gave it.
If this is the best idea in your mind for a guy running a stack such as his on an otherwise stock CR engine/turbo then you need to remove yourself from this forum or just stop posting altogether.csutton7 said:
ummm.. Csutton isn't exactly new to this stuff. And he was just stating a fact.CumminAtYa said:
Yes, I know that, but even someone who "knows stuff" should be smarter than to say something that stupid knowing the circumstances. Either lift, or turn the power down. Sorry, but that's my opinion on the matter. If someone has the budget for breakage and doesn't care, fine. I think it's easier to just do it right to begin with rather than have to fix things that may not have broken to begin with.Lucky Jeff said:
I don't get why you're calling him the idiot though? He only said "Of course his foot was in it, he was drag racing". Did I read that wrong? he wasn't the one that told him to do it. He just stated a fact. If I race, I don't exactly go out and hammer on it half throttle.CumminAtYa said:
I'll rephrase. Agreeing with those that did tell him to stay in it is almost as nuts. I don't agree with what he said, given the circumstances when the guy hit even 1500* racing or not he should have let off enough to keep the egt's under control. Sure his times would have been a bit less, but I am sure you could ask triton if he had it to do over again would he have lifted, or would have just "kept his foot in it because he was drag racing" and went through this dilemma?Lucky Jeff said:
