Well its a sad day, I had to watch my pride and joy being hauled away on a roll back. I was towing 13,000 including the passengers up a 6% grade for about 3 miles. I had been on the road for about 50 miles and the temp was fine but it went from about 190 to over 230 in about 5 miles and before I could get pulled over it made a loud bang then went dead. I looked in the intake and I know the turbo is froze up and you can see where it ate into the housing. I'm not really sure what broke but I will not turn over. After alot of thought I think the turbo has been going for a while and I wasn't getting enough air which caused the EGTs to go high and the engine to overheat. Which brings me to my two questions. 1 am I correct. and 2 I would like to go up one turbo size, what would that be and where can I get one. Thank you to anyone who replys.

jeez, what were your guages reading?? pyro and boost....

I dont have any, didnt think my mods were enough to cause trouble. I guess we learn from our mistakes they wil be put in before the next time I tow. I've read other post saying the stock turbo is enough for up to 350hp which is what I have. Is this true.

blackdiesel

you were towing with a modified truck, and you didnt have a pyro???? you probley could have saved your truck if you would have dropped 250 bucks on a pyro and a boost guage!

pulling over 10,000lbs up a grade, loaded with passengers with 350 hp on a stock turbo is enough to get too hot.

now you say that the engine wont even turn over?

Hindsite is 20 20. I know I suold have had them but at the time I didnt have the money. Oh well I just have to move on and learn from my mistakes. Yea its locked tight. I think it might have Hydrolocked with fuel or water. If need be I have found a complete motor to go back in. when we get home we will tear into it to see how bad it is.

Ouch, how do you know you have 350 HP and 35lbs of boost?

"Happiness is a high power hemi"

What are you refering to?

I had an cummins tech build my motor and he checked when he built it. I didn't need alot just alittle bit more. The more I think about it and the more I read I think I had a boost leak that caused the whole problem. Now I know if I had the gauges then I could have avoided the whole situation thats is why they are the first thing on the list to go in with the repaired motor.

Maybe it's this he's referring to....

It refers to the old 426 hemi. It came off the back of a 69 hemi dart that used to draggrace in the 60s and 70s.

I doubt it is hydrolocked with oil or water unless you drove it through a lake. If it's seized up it's because one or more pistons are melted to the engine block cylinder walls.

Sorry for your bad luck, better include gauges in the new motor build-up

Does anybody other than BD offer a gauge package that has a LCD display screen with all three displayed for the 94 to 98 12v motors. I would like to have something like that.
