8V71N bus - bad decision?

[Geoff]

Hey, I'm going to be in Vallejo next week.  I'll try to stop by and see what is happening.

Cool! Let's make the connection. I have one commitment mid next week.  Other than that free to meet

Send me a PM with your phone number and we can work it out.  I am not available the 17th.

i would be more concerned about a 35 year old cooling system than any other system on a coach.
if it doesn't have an over temp - low coolant shut down i would be very hesitant. you never know how close it has come to a melt.

notice i did not say warning buzzer light system.
i want a shut down. in the middle of a 6 lane interstate, before i would do without it.

You are correct, the cooling system is most definitely one of the first things to ensure is up to the task. Many units have upgraded the power, but not the cooling system. Some units are also limited on how much radiator can be utilized. 

Warning lights & buzzers are merely tools, when used used properly, they will save time & money. Used improperly . . . . you can't fix stupid. 

Since over 210 F is not good for the engine, I like my lights going off at 200F & a buzzer at 205F. That should usually provide plenty of time to determine the safest action without blocking travel lanes. ( Ever seen what a semi can to to a vehicle stopped in the travel lane? I'd rather replace the engine. )

With proper warning lights/ buzzers, there is no excuse for a shutdown to stop you in the middle of the road (except for a catastrophic failure).

I'm not inclined to repower up in hp/torque. It just seems like the value option is to get another coach already designed and built with the plant you desire. That way all the support systems are designed for that amount of power/torque/heat/stress etc.

All the talk about heat does anyone know the formula DD uses for the BTU heat rejection on a 2 stroke.I have it some where I am going to see if I can find it I recall it being 3 times more than a 60 series with the same hp

Don, don't be intimidated by DDEC.   I was initially, but then I realized that a scanner would let you troubleshoot so much easier than with a MUI engine.   Last year I bought a Pro-Link 9000 scanner for 1992 GM cars, complete with printer and cables and a case, for only $99, and a brand-new unused DDEC II/III cartridge for just over $100 including its manual.   So for just over $200 I can now read my engine and clear any codes.   The reason I bought a Pro-Link for GM cars is because it uses the same 12-pin connector as my bus's diagnostic port, avoiding the need to buy a separate adapter for $50.   These scanners and cartridges are always on eBay for cheap.

I saw that once upon a time when I was looking, but I have not been able to find it since owning a 8V92t.

Would like to have that info, would be nice to see how much more radiator I need to get the stabilized engine temp at full power to 100F above ambient.

air,fuel,compression....what else is there ?

unless that gizmo monitors crank thrust

Have you ever had your Coach through Citrus Heights, CA a few years ago. I saw one that looked like yours. It was pretty nice. Grey and black
Dave

[Geoff]

Yes, it was probably me.  My wife's sister lives in Citrus Heights and we have been staying outside her house for several years.  Now they passed a new ordinance that you can't park a motorhome for more than 24hrs. on the street so I am having to park in Roseville at my brother-in-laws shop.  We are going to be in Roseville next week but I won't be in my bus.

[Dave5Cs]

Yep told the wife it looked like your coach but I said it can't be because he lives in Arizona unless he is driving through or something like that. They got us on that to in CH so we put in our drive which was enough for 3 buses and then they told me it had to be behind a fence. I made a section of 6 foot high by 8 feet wide fence on rollers and just rolled it in front of our Bus when we were home. Ticked them off but we were legal according to their own rules, LOL
Then we sold our house and went on the road. We live about 6 months in West Roseville out where the old Ranches are off Baseline on a friends Ranch we help him with when we are home.

You can selectively cut out individual fuel injectors (useful if you think an injector is bad but don't know which one, or if you like to hear what a 5V92 sounds like), you can cross-check the accuracy of your boost and coolant temperature gauges and tachometer, you can check the fuel pressure (useful if you think your fuel filters are getting constipated), and a veritable cornucopia of other fun and exciting things.   I also could activate my cruise control if I so wished, but because I think cruise control is the invention of the devil I won't be doing that, ever!

Yes, I know even a DDEC engine is essentially still a mechanical engine, just with some extra diagnostic and control options.   DDEC is simply another tool in my toolbox.

John

That may be so, but that devil sure has saved me from a bunch of speeding tickets.

got my vote on cruse control . I can not drive anything with out . with the DDEC when I had my hp turned up from 277 hp to 350 hp they did it all on a lap top and it only took 10 minutes with no other adjustments . got to love that
