Here is excellent product, that keep radiating exhaust heat away from engine compartment. I can touch my friends Harley´s exhaust pipes at heads without burning my fingers: Thermo-Tec : Exhaust Insulating WrapWhen I used to test diesel generators at full load, the turbo housing and exhaust had the same red glow. I swear I could see the gasses passing through the manifold. Any metal will glow red above 1000 degrees, I don't see the point other than to make a point. Extracting that heat out of the cowling is the goal.
... The pics aroung the block showed the bell housing flange that doesn't look like the standard bolt pattern we've come to know. Did I see this correctly?...
That view is overly simplified to the point of inaccuracy....Also if an engine is pulling a constant rpm say 2000 it doesn't matter if its in a car, truck, stationary generator or aircraft, its still pulling that load. A car on the road at 2000rpm is still pulling a mass if it were not it would be at 0 rpm, a aircraft is doing the same thing in cruise flight at 2000rpm, no difference.....
There isn't even a boss where the bolt used to go. This is a standard sbc/bbc bolt pattern? Hmmm?
As you say, there are differences in the load an engine will see given the application. But to an engine, it matters not what is causing the load, only that there is a load..........kinda like the pound of feathers question.That view is overly simplified to the point of inaccuracy.
A mass on a horizontal plane does not require the same power as one up an incline, nor the same amount as one moving down an incline. Likewise, a 3 ton vehicle shaped like a box truck generates more resistance than the same mass shaped like a corvette.
Your statement is correct in that if the load is the same, it cares not what it is mounted in. However, mass is far from the only criteria that generates the load it sees.
Reply:Huh? So if my engine is running at 2200 rpm and meeting the needs of the moment, it will make a difference in whether its pulling an airplane or a truck?
Strictly speaking, it does: The analogy would be that the engine in an airplane , is subjected to the same kind of loading as pulling a truck up a steady incline, constantly.
It is not simply the RPM that matters, it is the BMEP developed. You can be be turning the engine at 2200 in neutral, 2200 going up a steep hill or 2200 going downhill. It's clear that it won't be subject to the same strain under all three conditions, even if the RPM's are the same.
A good reason to set up the engine to be a "towing" engine as far as cams and valves are concerned.
There must be a sizeable number of people who have some interest in conversions, especially aluminum V8 conversions to generate that many views. /QUOTE]
I'm one that has been following this thread with interest but have no real need for this class of power. The reason being that the basic cost of operating a plane, of any kind, has forced me down to the low Hp ranges so I have the option to fly more often, rather than faster.
Being able to building a direct drive V8 based engine for a whole lot less than Lycosaur (yet still be reasonably reliable) just might be justification enough to move up the food chain to a faster aircraft that that would actually be useful for travel with gear and a full fuel load. A $10k savings on a proven engine buys maybe 200 hours worth of fuel? That may not seem like a lot but once you consider that this would be a second plane that is only used for travel, 200 hours could be a decade of time for those of us that mainly fly for pleasure, but would like the option of serious travel without the hassle of renting.
There is a whole lot of potential here and a couple of proven examples may spur a whole new branch of experimental engine conversions. I suspect there are plenty more like me that are very interested in this line of engine development but just don't have the time or knowledge to offer anything constructive to the topic.
Most auto conversion threads generate a lot of views on any forum. People would love to see a low cost, reliable solution that they can easily get parts for and work on themselves. Others just like to watch people bash people experimenting with auto engines...Has anyone else noticed the inordinate amount of views this thread has generated? And it doesn't have as many replies as some other threads. There must be a sizeable number of people who have some interest in conversions, especially aluminum V8 conversions to generate that many views. Although I din't go to the trouble of verifying it, this is probably one of the top ten threads on the site.................
