I don't care if anyone agree's or disagree's, but this dude seems like a total scum bag. Could be the nicest guy in the world, but he sure gets a great rep around these parts. :roflmao:

I'm not one to stir the pot, and by no means am I trying to throw anyone under the bus, but I figure after all of this I should put it out in the open...

A few months ago I bought two turbos (GT4094 and a Precision GT5088) from MD-Dmax. The GT4094 was supposedly a complete PPE kit, but it came with no downpipe. It took countless PM's and many weeks, along with Henry's (ripmf666) intervention, to get the downpipe shipped to me.

Even worse, after installing the big turbo in a compound setup on my motor, it ran for about 6 hours before the larger charger (supposedly a brand new GT5088 from Precision) grenaded. The compressor wheel exploded and sent metal bits through the GT4094, destroying it.

All in all, it ended up costing around $12,000 (new set of Mahle pistons, rods rebuilt, machine work, gaskets, replacement turbo parts, etc etc).

The GT5088 from MD-Dmax was run with an aftermarket 6" cone filter and custom made intake. It was never run without a filter or around dirt, sand, etc. There is 0.0% chance it inducted foreign debris through the filter. Ben (duratothemax) helped me do the build and will verify that this setup was never run without an air filter).

I'm not saying that MD-Dmax caused this or it's all his fault that I cracked a piston. I'm not laying any blame. I'm not accusing MD-Dmax of selling me a damaged turbo. I'm just saying that it seems mighty suspicious that a supposedly brand new turbo from Forced Inductions just grenades... Especially given everything that's transpired in this thread.

Take it for what it's worth.
Wow sorry to hear this sounds fishy for sure

That's what I thought too. But I didn't want to post anything up and throw MD-Dmax under the bus.

I figured it could have been a fluke, manufacturing defect, or whatever. But in light of everything here, I feel as though it's appropriate that I come out and say it now.

So how can this happen with 3300 miles on the motor? Just blows my mind.

Well post up when we find out I am curious myself , oil supply problem on truck or that turbo , containment in line or turbo during install , defective turbo ( it happens ) , boost leaks can over spin chargers , plenty of other things . I talked to Kervin tonight and he is shipping us the kit back so we can go through and check everything out and have the turbo's checked out before there re-sold .

If you read back after the motor was first installed it had very low oil pressure and had to be pulled out. There was a plug or o ring left out so not sure what that could of hurt.

Oil pump sealing o-ring?

If you leave it out, you'll piss almost all of your oil pressure out between the oil pump and block....

The triples weren't even on at the time of the low oil pressure ordeal so thats not the issue. I think they were just put together poorly but weel find out for sure here shortly.

I stole my LB7 and im happy I did it. Plus your trans is a mare 3000 miles old :D



No, it's not a steal, because it's broke! 20k boat anchor..

The trans is older than that. All we did the second time around was a nose job. It had a bad pump, bad converter,and broken bell housing that was welded wrong. The engine guys dropped the trans off the jack and broke the bell housing. It landed on the converter. They did a quick weld job, misaligned the dowel pins and his problems started.
