Think I found part of my problem...

Got the engine out to swap Pistons, and saw this. Passenger's side up-pipe.
I made my own H2E type mount about 4 years ago and didn't have any expansion provisions, just solid pipe to turbo.
When I unbolted the driver's side pipe at the exh. manifold, the pipe pulled away about 1/4".
When I unbolted the passenger's side it pulled away about 1/2". I found a spare set of pipes I had an noticed this:



Driver's side pipe looks fine, but seems to be a tad short.
I'm guessing I had some pretty bad exhaust leaks at the exh manifolds as well as my v-band coupler, which I can see lots of soot around that.
Then I realized 2 years ago when I had my turbo mount machined flat and put the v-band in, when I first had the truck on the road it ran great at the track. All last year it sucked big time, now I know why. Over that year the pipes had to have pulled away from the joints, letting lots of drive pressure by.

Ooops....

Re: Think I found part of my problem...

I wondered how it would work when you mentioned you didn't have any expansion provisions.

Re: Think I found part of my problem...

There is a fix to that

I didnt want to take a chance cracking headers, they arent nearly as strong as manifolds.

Re: Think I found part of my problem...

Shouldn't someone be able to hear that kind of leak? After a couple of years I guess you just get used to it?

Re: Think I found part of my problem...

I know all about those bellows, I found them after I built the turbo mount. Which was 5 years ago, not 4...

I would have thought so, but I never heard any exhaust noise at all. Maybe the motor/stacks drowned it out too much. Or maybe they really weren't leaking that bad. Though I'd have to think they were.

Junkie,
You're in for a treat if you ever try to get that turbo mount off the motor, with the motor in the truck. I did the same thing, built it on the stand, mounted it, then put the motor in. I had to cut it apart to get it out, that's when I put the V-band clamps on it.
Now I have to re-do the V-bands and add those bellows and all should be well...
