Re; Sluggish 8V
Even after ckecking all other factors, I would have the valves and injectors
checked. I had mine done at 200k, and while the valves were good, the injectors
needed adjusting. Now has more getup and go with less smoke.

Re; Sluggish 8V
From experience, I would check the exhaust to turbo pipes. Sounds like one of them has developed a leak if it is totally gutless at take off but seems ok when up to speed. Look carefully at the flange areas inside the clamps that hold them to the exhaust manifolds. You may have to loosen the clamps and remove the pipes to check the flanges. A good truck parts house can supply flange extensions to replace the bad ones if that is it. The pipes themselves are VERY hard to locate, even used. Don't ask how I know. LOL
Let us know what the solution is.

So, all of the rest of you with 8V92s are telling us they practically hop off
the line?

Re; Sluggish 8V
Some of you fellows might remember Powell Brown's coach during the Balloon fest this year.
His symnptoms sounds just like Jerry's, painfully slow on start but once when up to 1500 rpm the power was there.
We have been chasing the problem for the past two weeks, and took Mike's advice, but first only did one side, and it seemed to help, then finally we did the other side and although not quite as quick as "Vadies" it seems to have a lot more getty up and go.
Yes, 3 of the 4 flanges were leaking, not much either.
The revs come up a lot faster.

Re; Sluggish 8V

Bill,




Glad to hear you guys found the exhaust to turbo leaks and got Powell running better. I tend to view internal combustion engines as just pretty simple big air pumps and once running they only need a few things to continue to run: fuel, air, and compression (diesel) and/or spark in the case of gas engines. When you are running good on the highway and then exit and stop at a red light and old ladies on walkers beat you across the intersection on the green, those exhaust flanges need to be checked as a potential culprit, because if it was fuel related you most probably would not have been running good at speed on the highway either (witness clogged fuel filters). Every now and again, when checking stuff while the engine's cold, I shake those two exhaust to turbo pipes just to make sure they are still tight. Those old
V92s shake stuff loose and they need all the air and fuel they can get to start to move those big Birds.




See you folks soon.




TGIF
