| RE: Turbo I will attempt to address this a bit, but even if you don't believe me,... I can simply wait until your pop your engine a few times, cry about it, then come back and start asking how to get it right again after you have spent $20,000 - $30,000 over and over for a few inframes after trusting in your "so-called guru delete shop" guys. You have been brainwashed by some real idiots there it sounds like ... (06-18-2018 )Roberts388 Wrote: Truck is a 2018 pete 388, yes its a 565/2050 X15. I was thinking it still might have been cm2350 as thats what it says on the ECM. Running tankers n dry bulk in the northwest up to 105,500 gross. First of all, to enlighten you a bit --- The new X-15 higher HP model has 19:3 compression ratio in it from factory, unlike ANY PREVIOUS MODEL ENGINES!. Not even the CM2350 does this, as it is tuchy as hell at its 18.9:1 ratio, and older engines that used the 500 series Holset turbochargers were down in the 17 and 16 ranges. -- In plain English -- THE X15 TAKES FAR LESS BOOST TO MAKE THE SAME POWER than any previous model engine... PERIOD!, so if some ignorant moron is stuffing in more than about 28-31 lbs boost AND on top of that, IT IS DE-MANDATED,... YOU ABUSING YOUR ENGINE VERY BADLY!!!. YOU CAN MAKE CLOSE TO 800 HP WITH ONLY roughly 31-32 LBS BOOST ON THAT MODEL ENGINE! ------------- (06-18-2018 )Roberts388 Wrote: ...That is fine and well, but there are so many BAD DELETE SHOPS out there talking a good game that it is not even funny,...

I would hate to see what your oil temps and other things are.

YOU HAVE A BAD DELETE AND YOU HAVE BAD PROGRAMMING BY A BUNCH OF IDIOT REDNECK PICK-UP TRUCK TUNERS HELL BENT ON DESTROYING YOUR $36,000 ENGINE!!! They obviously HAVE NO F$KING CLUE that engine has full HCCI injection in it, higher than normal compression ratios, light-weight composite pistons that are sensitive to abuse, etc.etc. nonetheless how to control it. Let em keep guessing,.. Are they going to pay for your inframe it is going to need in its very near future?. Are they going to supply you with free turbochargers on a regular basis as they fail repeatedly due to abusive overs-pooling due to bad programming and such blind ignorance? -- Your on the fast track to engine destruction. (06-18-2018 )Roberts388 Wrote: ...I would like to address this specifically, as there are a LOT OF IGNORANT TUNERS OUT THERE on other auto tuning forums who reference this same data/chart. That document + chart is a decent reference, but some of it is very misleading in reference with todays engines. The things like air-flow, the AR ratio chart and other things are correct, but the KW rating listing itself is VERY misleading. It is based on 16:1 - 16:3 compression ratio/older engines THAT ARE NO LONGER IN PRODUCTION!. What is important is the AR ratio and air flow capacity. I.E.> LESS BOOST REQUIREMENT FROM THE ENGINE results in a smaller turbocharger handling A HIGHER HP/KW CAPACITY!. The 400 series Holset falls squarely in the range of AR/flow ratings when considering the requirements of the CM2350 and the X15 engine. The engine maker did not "undersize" the turbocharger at all for the power rating you have. Here is some roughed-out info for the CM2350 (18.9:1 compression ratio) ... http://rawze.com/forums/showthread.php?t...9#pid20049 Real world experience with them clearly points to the 400 series handling, peak, about 660-670HP on the CM2350. This would be the case with the X15 as well. - A 500 series on an X-15 will actually handle more power than the engine can produce without other serious mods. Anything larger than that would be negligible at best. For those who have application for it, (higher than normal average torque load applications), my earlier post still applies though... http://rawze.com/forums/showthread.php?t...8#pid27848 (06-18-2018 )Roberts388 Wrote: I drove a 2013 ISX set at 450 before this truck and never heard exh flowing thru the egt cooler but with this engine I could hear exh flowing through the cooler at anything over 1500 rpm and 20 psi. Sense that it shut off now all the exh is driving the turbo and causing high boost pressures. Measuring and monitoring the exhaust to intake pressure ratio will reveal this. The Pete 388 has a considerably large charge air cooler from the factory, it is NOT your problem there. That is, unless you were stupid and put on one of those restrictive "duraf%ck" after-market CAC units, those things have terrible air-flow. Your problem is that bad programming is over-boosting the crap out of your turbo. You have no clue what is or is not "ok" or "restrictive" at this point at all with regard to the truck components. ------------- (06-18-2018 )Roberts388 Wrote: ... I hate to say it but you have been around a bunch of blind ignorant clowns. Your squarely caught up in their ignorant ways. I don't tolerate such redneck dumbarsse tuning and mods that are hell bent on destroying the engine in the name of "power, deletes, and custom tuning". If you still disagree with what I have pointed out here, then I would suggest you go hang out on a tuning forum where such engine abusing crap takes place and they can argue bullshit like 50+ lbs boost and "dumping in fuel' is somehow ok for something with such high compression ratio and precision components ... In that case, this place may not be for you!

You never mentioned the gear ratio etc. You seem to be hell bent on big power,,.. and I understand that some guys are, but you are likely way over-thinking it and possibly looking AT MODIFYING THE WRONG DRIVE-LINE COMPONENT if what you have is not working out for you. A better rear ratio will ALWAYS outshine any mods you do to that engine, AND IT IS MUCH CHEAPER!. - Just mentioning this as a reminder. What is the gear ratio anyways? (06-18-2018 )Roberts388 Wrote: ... As to what leads me to believe the charge air is running to hot is the compressor has turned from the bright cummins red to a very dark maroon color.I think by now you have an idea what is wrong?---- BAD PROGRAMMING AND OVER-BOOSTING!. It is killing your engine and turbocharger, and you have best HOPE LIKE HELL that the permanent damage has not started taking place yet. After looking at that picture, I suspect damage has already been done though. It is likely a matter of time now. That much abuse and over-boosting will fret the liners right out of that thing in a hurry. Even after you get it right and straighten it out, it may still likely fail at this point based on what you have described. I don't know of anybody that would not cringe and not want to touch it based on just that alone. Your path to a pre-mature inframe seems to already be set, even if someone does straighten it out in the near future, just warning you. You, and the guys guessing at your programming blindly seem to be on a clear path of engine abusive destruction for the gain of a few HP,... Sad indeed!. (06-18-2018 )Roberts388 Wrote: ... Up to about 660HP is easily done in that engine with its already existing 400 series,.. WHY? -- Because of the already very high compression ratio,.. it requires less boost because of this. it will not even get close to overheating and causing the problems you are describing there,.. it is bad programming that has got you, not the turbo!. However ... The 400 series is not ideal for making 600+ hp and above. The 500 series will better suit an X15 engine that produces more than 600HP, however it is NOT MORE BOOST you looking for, but better charge flow rates. With a 500 series, it will require SLIGHTLY LESS BOOST PRESSURE to make the same HP as the 400 series did. The engine cannot exceed the flow capacity of a 500-series turbocharger (engine runs out of fueling capacity at just under 800 HP form what I have heard), but then again you will loose low-end response and loose overall fuel efficiency with it too. I.E.> It comes at a cost, hence my mention of changing rear end ratios so that you can get the engine up in the HP working band (1600+ rpm range) when going down the road and in hard pulls and out of its liner-fretting torque band (below 1400). Those idiots trying to tear your engine up with all their ignorant guess work is the actual problem. If they had any clue whatsoever how to tune an engine with the specifications of the combustion chamber and its injector design, they would have known these things and never let it get anywhere near that kind of boost pressure or the other things you describe.
