Non engine related HP loss

My comment about the superiority of computer controlled EFI was directed at temperature and humidity. I said nothing about altitude. That's a whole other ball-o-wax.

The bottom line is the O2 to fuel ratio. Obviously, nothing can manufacture O2, but a computer can certainly maintain the proper ratio. Adding an O2 system really ain't practical for everyman - unless your bizness is professional racing.

British cars......OMG. Back in college one of my classmates was a sports car nut. He and his father and uncle ran a sports car repair / detailing / restoration shop. He told me they wouldn't even let a brit on the property, much less work on one. But that's just him. I once drove an MG-B and I didn't want to do it a second time.

I just didn't fit. "First Shirt" in the USAF was a Brit. decendant and had that one while I was stationed there. Tried it once and that was enough. He was always bitching about tweaking the carbs and trying to get them happy with each other. His was a "rag" top. Don't remember about the windows.

Keeping this "legal", I didn't do any boating over there so I can't comment on weather effects on marine engines.....Grin

Diesel motors performs much better at high altitude than gasoline powered motors..

Why? Wouldn't see a reason diesel vs gas would be a determining factor in altitude. They both need oxygen, and are both limited by oxygen at altitude.

Now most diesels are turbo which changes the altitude problem dramatically. But today many gasoline engines are also turbo, and perform great at altitude. (my little turbo 4 cylinder Subaru WRX burning corn juice loves a good twisty mountain road!)

Now is much different than "when in the good old times" as everything with a motor has evolved for the better..

Happy Boating
