If you never barked a 35/40 your not driving it hard enough or don't live in a big city. I was trying to get onto hwy 99 had to really go and exploded the whole thing when I shifted. Parts were found in piston and every where else

At least I know the limits of my equipment. Yeah, I know how far I can push that turbo. Remember its only a 12cm² housing. Excessive driver pressure will over spin the compressor and if it's out of balance just a little it would go to piece like your picture of yours. These things spin at some seriously high RPM's and reaching beyond what it capable of is risky at best. Sorry to see this kind of damage, sucks to have to rebuild an engine because of turbo failure.

I talked to Rip and he said when he blows 3 or 4 turbos is when he rebuilds on his race truck. Only reason I bought a long block was the major crack.

My turbo was a 14cm and in past when on a dyno I could hear squealing from the turbo.

It sounds like the engine ran after until the 53 block cracked, so no permanent damage from the turbo blowing up?

 

Edit: @Mad Bomber I didn't see that you replied until I clicked send.

Yep still ran till we ran out of coolant on the side of hwy. We were still 150 to home. So I used water in the trailer to refill multiple times. Last 30 miles or so I just continued to drive home with not much in it and getting real hot.

So did turbo have anything to do with rebuilding or just the cracked 53 is why you rebuilt it. Didn't some turbo pieces make it to engine?

[Mad Bomber]

Just the #53. Yes parts were in intake I also had marks from pieces all the way though

How the hell did the pieces make it through through the intercooler?

[Mad Bomber]

I could see where the pieces had gouged the other side of intercooler and even the piece before the grid heaters. I was surprised at the number and also the size of them. I guess just the force of 40+ psi and sounded like a M80 blew up under the hood. I also had 100's of pieces in the air filter. Just expand the pic and look at how much is missing off wheel

So would a blow off valve prevent this failure or was it over spead and flew apart.

I think it might have BUT then I have no excuse to buy a better one. LOL
