is a 58cc gasser which is supposed to put out more than most 80ccgassers. It also weighs 3 pounds, producing an incredible 9.25 Bhp..(!?) It is not out yet, but that is amazing if it is even close tobeing true.J

Joel, that doesn't sound unbelievable to me. The full scale motorcyclemanufactures in Japan, Ie: Honda, Yamaha etc. have been getting far betterhorsepower to displacement ratios than that for some time now with their 2stroke motocross bikes. Some 125cc racers produce over 30hp and can bepurchased at your local dealer. Sooo, the technology is out there for thiskind of power per cc, especially with today's microprocessor controlledignition to manage the spark timing, the weight seems a bit light, howeverwith the right engineering it is possible.Tom WalesAMA 435536

Do these specs seem believable?

Yea, I guess if you wanted to hang a 29 speed gear box on the Jag engine and suffer from having to stop every few hundred miles to overhaul it (not to mention the broken parts from revving the snot out of it just to get the load moving), I guess you COULD use a Jag engine in a lorry.

The real reason is that lower revving diesels with their massive amount of torque are far better suited to hauling heavy loads. Same reason a Nelson FIRE isn't used in aerobatics.

And, if you think fuel economy isn't important to lorry operators, you are in a REAL fantasy world!

:) Basically you can't, not for the very best anyway because they're hand built. These are the 2.5cc CL speed engines and very few people have the expertise to use them. The last figure I read about them was about 5 years ago where the then world record holder produced 2.7HP on the dyno (you don't get inflated manufacturer's figures with them :). Next in line would be the nitro boat and car engines and possibly pylon. Their specific power is more limited because they need to have a somewhat broader power band for acceleration so pipe settings aren't as critical.

That's the Brit term for 18 wheeler.

No, that's 'juggernaut'
