I'm seeing that not all 360s were created equal. They range from around 175 HP on up to 210. I can account for this between carbureted, Injected and TSI engines.

I see though that for example the TSIO-360 A , AB & D, DB are all 43 pounds lighter than the others. All of these are TSI engines. Can anyone account for the lighter weight?? They have the same dimensions as the others except that these are 1" longer. Width and height are exactly the same. All are 7.5 : 1 compression ratio as well. They also seem to have the lowest TBO of all the 360s.

Can anyone give an explanation to account for the lighter weight?

Hey Jim,

If I had as much money as Whitebear, I'd just go ahead and get one of these:

Just Joking Whitebear.
If I had the cash, I would buy one.
They plan on an industrial version at a reduced cost, but it still would be an expensive engine.

I think this is the way piston engine aircraft technology is going to go in the future.

Full take off power on #2 diesel with out worry. That would be nice.
 
Hey Jim,
Would the consumption rates for alcohol be really high.
Would you have to have like double the amount of fuel capacity for the same gas powered mission?

Just wondering cause it seems to me that aircooled engines would love methanol, and the way it seems to cool things down when used as an engine fuel.
 
cowboy,

Strictly from memory, I think the fuel consumption is about 40% more on alcohol. There are other issues like corrosion and it can attack some seals and gaskets too.

I'm glad to hear that your brother's boat sold.

Yesir, quite a bit higher fuel consumption. The valves and valve seats would have to be changed also.
Alcohol was outlawed by USAC several years ago because you can't see any flame in daylight if there's a fire, and it's a lot harder to store than pump gas, even though it doesn't breakdown like gas.

A plus would be that it removes moisture from a fuel system ..... alcohol and water will mix.

I was going to buy a wide deck heavy case 180 from a guy who has it sitting on the side of his house. It needs a top job but the lower half appears to be good. He wants 3k for it. That is the BEST 4 banger around.
 
Is the Wide deck and narrow deck synonamous with the parallel valve and angle valve cylinders?

I love a hemi no matter what it's on/in.

I have been aware of the Deltahawk engine for quite a few years now. Just prohibitively expencive for a water toy.

Cowboy, if you had my money you wouldn't be running an airboat ! hahahahahahahahahahahahahahah

Yeh I'm kidding too. But I do try to get the best bang for the buck otherwise there won't be as many bucks to go blowboating on.

Since Osama Ben Laden, this is the first time I have been able to seriously look at light weight stuff, always built Buicks because I HAD to go automotive and that was the best bang for the buck out of a car. So in a way, Ben Laden has done well by me !

Wide Deck vs Narrow Deck.

The narrow deck engine is the old style Lycoming engine. In this configuration the cylinders are bolted to the case with the addition of a number of "half moon keepers. "

The wide deck engine is the newer style and just uses hex nuts with no keeper. The flange on the lower portion of the cylinder is thinner on the narrow deck that on the wide deck.

My 0360 puts out 240 honest HP it was over 20 years old when I tore it down for a rebuild, can't ask for much more than that for dependablitily.
I just don't understand what people see in car motor boats ?
 
Just out of plain curiosity I would like to know how your 0360 made an honest 240 HP. Was it injected, supercharged, or a turbo?? Or two out of the three?? Did you put it on a dyno?? I had an 0360 on my last boat and loved it. There are several reasons people goto "car" motor boats, just do a search (I ain't opening that can of worms)............

According to the information I have on Lycoming O-360 series engines, the best Lycoming can do is 210 hp and that's with a turbocharged engine. Since I've got an O-360 on my boat I'd be interested in knowing how you came up with that much hp also. I'm sure Lycoming would be interested.

Lycoming's lowest rated engines ( O-360-D1A,D2A, & D2B) only put out 168 hp. They use 7.2:1 pistons. Aircraft engines for the most part are built for durabality as opposed to hp. With the exception of racing engines.

For a true perspective of what a warmed up aircraft engine is capable of I can remember Dick Hoffman beating almost everybody (that includes car engine boats) with a supercharged O-540 Lycoming. The only folks that were able to beat him were those (the ground rattler and a couple of others) that had a ton of money in their engines. He did all that with an old runout aircraft engine that he worked on in his shop.
