Engine Capacity - Page 4

Bunyip · March 26th, 2012, 01:16 PM

David (Krop), you must have done your sound analysis by now. So is the Ducati 930 0r 999 cc?

Could it be that Ducati purposely put that tacho on the bike in clear view of the journalists to lead them astray? Would they do such a thing?

The results must be in by now...................................

Since CRT is running on Spring Valve, they should be allowed to run on bigger engine capacity i.e 1100

maybe 1200cc for twins but if the capacity for 4 cyl would be raised none of the superbike engines would work. they would have to make the bore larger/stroke longer which i guess is quite a job.

in my opinion the mistake was to introduce the 1000cc formula for prototypes in 2012 instead of 2013.

800s vs CRT would have made much more sense than having a new set of rules for just one year

Ducati may be running a 930cc unit derived straight from the 800, and have a completely new 1000cc engine still in the testing phase. So Preziosi is not really lying when he says the new bike is (going to be) a 1000. The new engine will also be lighter (not being designed to function as a stressed member like the current one) and nobody knows if the angle between the cylinders will still be 90° or less.

Due to the difficulty Rossi had on the 800cc Ducati, they weren't sure giving him the extra 200cc in one lump was such a good idea.

He'll get another 60-70cc next round

Totally agreed. But I believe Japanese Manufacturers: Kwak, Suzuki produce 1400 - 4 cylinders..

yes , but if you compare the newest zzr1400 to a s1000rr engine you'll see that they don't put out more power at the top end because they can not rev that high. those engines offer phenomenal torque because of the big capacity and relatively long stroke ,great for accelerating in a straight line in any gear ,but i don't think they would be the best choice for racing,those engines are very very wide. have a seat on a hayabusa and then on a rsv4

maybe crts should be allowed to run turbos, that would be fun and real prototyping

They are not. It is a massively complicated operation, sorting the signal from the noise. I am rather dismayed by just how difficult it is.... I'll post a shot of the sound file later.

Look forward to it. Thanx
