OK, Fine I will give you the one on the "dampers", Honestly I have never seen a bus equipped with them and even while shopping for my MC9 didn't see any on any of the NJT buses on the lot of about 100 or so 83's and 87's all with 6V92TA engines.
Didn't see any on three other earlier year models either. 1980, 81 or 82 models.
They may have been standard or optional at some point. So OK on that.
Yes, a Cage Blower does not suck as much horsepower if the shutters are closed.
That is an assumed fact whether you have dampers or shutters.. Say approximately 5 to 15 hp maybe.. who really knows.
TB... Why would I make a bet about that. I don't think so, Mainly because I wasn't
the one that said it or made a comment per se...
The general rule (loose) is 0 to 60 in 5 miles with a stock 6V92TA MUI at the factory 277 hp coach rating. On mine maybe 3 miles to 65 on a good day.
The best mileage I have ever gotten was 7 mpg, 6.5 down to 5.5 is the real world average with a full load and 8k trailer following along behind. I use 5 mpg as the general rule to figure when to stop for fuel or just top off evey 200 miles or so.
Fuel capacity should be in the range of 8 hours at least. I don't know about a lot of others but I have to get up and walk around at least every 3 hours and to drain the reserve tanks. That's why I never worried about a working fuel gauge and won't lose sleep over never getting mine to work.
The only bus I had that got really poor mileage was my RTS and that was with the factory air handler a/c running came out to 3.4 mpg.. 5 without it...Of course the engine was worn out anyway and finally blew up when the blower drive broke.
As for the TURBO effect... It's not really something that you can feel on lazy old detroit 2 strokes. You can hear it at higher rpms on some buses, But usually its just a hidden sound and working part of the engine.
Chaz.. Slow down, You are all over the place and starting to babble randomly.
Somebody please go visit him and help him figure out what he has. I would go but can't afford the 800 mile round trip and 3 days it would take to explain stuff to him.
As for questioning my qualifications. Go ahead... But be forewarned... I get a bad attitude when people start talking out their shaded side.. Charmin to the rescue!

( or was that altitude? ) I do know (or did) my mechanics, electronics,avionics and many other fields long before I got my own bus(es).. I can and do make mistakes and I am far from perfect.. I started converting vans and old school buses for people before I had a drivers license... Like back in the late 60's
I have been a machinist and worked on military and nasa items. I have engineered data, radio and mechanical systems for several companies. I have driven passenger buses and trucks professionally. All in all, There's not much I haven't done at some point in life. I figure stuff out. I watch TV and sit in complete awe at the antics on Mythbusters and have done a few of the featured jobs on Dirty Jobs too...
Mike Rowe needs to help strip and clean a bus sometime. That's is a really dirty job and it don't wash off very quickly either.
Sorry, I drifted again OT, OH, OHNO.....
Bye...
