What engine should I look for?

[Scott & Heather]

Geoff has a point too that should be considered. My mechanical 6v92 was so simple. Air plus fuel and bang bang. My DDEC II 8v92 is different for sure. I love it on one hand because the throttle is electronic. No cables to mess with and smooth easy pedal action throughout the throttle input range. I love that the engine has a good check and balance safety system for low oil or low coolant or overheat and shuts down accordingly. I love that I can hook a prolink to it and read all kinds of amazing data from RPM to trans temp to boost psi. I love that I can customize how much fuel gets pushed and at what rpm. I can control the pulse width tables for the injectors and control the idle rpm and delete the top end governor. I love that I can see on a screen exactly what's going on in the important areas of my engine. Ken Arnold has taught me a ton, but I still have much more to learn. I'm getting there and some day someone will ask me for help with their DDEC II engine. But on the other hand, I've had some horror stories of sitting in the desert of New Mexico with a coach that died for no reason other than a relay pooped out and it took four days to find it. That kind of electronic gremlin stuff can drive you mad. But after four days of coaching from the guys here and Ken Arnold over the phone, and utilizing the 500 page DDEC II manual I have a much much MUCH better understanding of DDEC II, how it works, and how to troubleshoot it. I'm 34 years old so I have plenty of years to continue to learn this...every new bit of knowledge decreases my two stroke anxiety a little more and if you're that type to get down and dirty and figure this stuff out and troubleshoot, then a two stroke is fun....and a DDEC two stroke is just plain euphoria.

Keeping a 2 stroke cool is a major under taking they are the hardest to cool of any engine ever made,I see people with lawn sprinklers,misters and all kind of rigs trying to cool it.

I have a Eagle here now that was running hot with a 8v92, a radiator was made and sent from Atlas in Texas 38"tall x 46"wide 9 cores $2500 bucks and the fan is another 600 bucks. 
This was the size radiator all the calculations said use for the heat rejection on a 475 hp 8v92 by the time I am through with fab work, moving batteries this will be a 5000.00 job,a 60 series would use 1/2 that size of a radiator

So..what you are saying is that the 92 series in that coach was not stock...otherwise it would probably never overheated

And refitting a proper radiator (not stock) in a 1956 F1 Ford would take the same amount of $$ in mods if you were pulling the old flatty and sticking in a 406 tri-power C6 it's all relative

 The 8v92 have always been a problem to cool even with the factory set up from Eagle,this one going to have a larger radiator than the stock 38 x41 with a larger dia fan with the 12 blade variable pitch

A set of dash gauges will give you all the information you need.  It is not fun having your bus towed into a back-woods shop when it quits running and the mechanics look at you as though you are a geek when you start waving your 500 page DDEC manual around.

I have a 3406B in my truck conversion-and can say it is the most reliable engine ever made (had trucks with 8V-92TA, 6V-92TA, bus with 8V-71). Cat still makes the 3406C mechanical for third world countries that don't want electronics. Good Luck, TomC
