160 bhp air cooled engine. Tempting?

[stopintime]

I'm not getting much sleep for a while 

3V prototype 650cc 82bhp - an 1100/1200/1300 with two of those

Hmm. Same bore as the 800. Could potentially work easily and be over 100 hp.

[zooom]

now THAT has some serious potential!

[bikepilot]

hp does not scale linearly with displacement.

I do like the idea of a rockin 3-valve air cooled twin though.

Umm, didn't Ducati already have a 3 valve motor??

Ducati.com shows the 2007 ST3 and ST3s ABS as air cooled     Mistake?

all ST were watercooled.

saw a prototype 3 valve aircooled monster  that snuck out of the factory in 93 or 94 for sale in france recently

but the ST 2, 3 and 4, of course, were watercooled

I initially thought these numbers were for the power of one cylinder, which could be doubled.
Obviously wrong and of course not doubling'able.

My knowledge of Rüdiger Kämna's mind tells me he's doing this because he thinks it's possible to create
more power than his 125bhp big bore 2V air cooled (although probably heavily oil cooled)

I'm sure he won't stop until we see at least 140+

Put that in a super light weight chassis

And give it to NCR for a New New Blue.

i think i read somewhere that Ducati abandoned the air cooled 3v due to heat issues.

The page says that there are approximately 25 existing prototypes.  Hopefully this project produces some good results that make it to the street in the form of bolt-on aftermarket heads.

It'll be hot allright  

Maybe that's manageable with a lot of gas, a very open exhaust and a couple of large oil coolers.

"Race use only" ?

Didn't you do your engine recently?

Still want more

3v 620 yields 77hp

notice the oil line going to the cams that comes off the oil pressure switch port.  same way old pantahs would cool the cams

I'm curious. 

I do have the additional displacement up to 1123 cc and the mid-range has experienced a nice bump which is great for the street ride.  But to get serious horsepower in the upper range the heads will have to be re-done like with this 3V project.  I've seen the descriptions of 120hp 2V engines which are impressive, but this 3V project will have more potential for big HP numbers because of the straighter intake.

Weird, wrong weight, fuel capacity, front brakes, power and who knows whatever else is wrong too
