Ducati MotoGP power

not too familiar with the spec ECU deal but if all the manufacturers have the same governed amount of spark control then some engine designs are bound to work better with that than others.

 

They also started in on the "standard" electronics last year, so a significant headstart.

Single sided swingarm and trellis frame.

And the year pedrosa was fastest, Rossi was there and fucked up the bike development.
Mine they got stoner back and look who's fastest.

Coincidence??

 

That was last season.

Aren't you supposed to be the resident Suzuki expert?

 

LOL ^^^ thanks for the correction

 

Italian cams?

 

Ding-ding-ding!

 

DESMO!

nothing can move / force the masses of the valves as fast as that system.

pneumatic springs at 15k RPM? Pffffft....

 

Why is that? Cost? Reliability?

 

last i heard, GP teams refill the compressed gas system daily. thatd suck for a consumer vehicle.

 

Is that why Ducati licensed the desmo drive system to all of the F1 teams back when those engines revved over 19K?

 

well the motogp engines also rev 18k.
but fact is, that the pneumatic valve system still needs a rocer arm or something to get the valve down and then the pneumatic spring has to move it up again. so the rocker arm (or cam alone) has to work against 1. the mass of the valve 2. the spring load 3. the partial cylinder pressure

on the desmo system, the spring load is not required, thus resulting in higher dynamics. also, there are less friction losses (sealing of the pneumatic spring)

 

I'm just playing devil's advocate. On one hand, if desmo were so great, somebody would have copied it by now. On the other, racers (GP in particular) are notoriously resistant to change. Look at Moto2 - they were supposed to have set drivetrains but were free to develop chassis, and nearly all of them have gravitated to the same chassis.

 

id be very surprised if the desmo system wasnt heavier and had more rotating mass than a pneumatic system. its likely also makes for a larger cylinderhead, and we know how important packaging is for a GP bike. desmo has its drawbacks just like pneumatics.

IMO, the desmo system is not why Duc has a major HP advantage. theyve been chasing usable HP w/ this engine config since at least 2014. HRC has been doing the opposite for that time and Yamaha has mostly improved their braking stability. Duc also fought the wheelie with all those winglets and their use of the spec software for acceleration and wheelie is on-point. all that adds up to their crazy advantage.

 

At those speeds the aero package is as important as pure HP. Wind resistance is cubic, at a certain point drag out weighs HP for top speed. I did notice other teams copied the strakes (winglets), maybe they do more than just help with down force.

 

large endplates on the winglets would def affect the airflow around the moto dramatically. the other riders have been complaining about drafting the Ducs for a while now. the GP15 and 16 are also a bit smaller/narrower than the GP14, so im sure frontal area was decreased.

 

Seriously, I must be getting old, everyone knows it's because of the ITALIAN CAMS!!! just ask Mr. Cobb....

 

It leaks by design, some of the gas keeps escaping into the cylinder or head or wherever it goes, it's a racing only thing.

I'm not sure how Ducati has anything to do with who uses the technology, IIRC it was Mercedes that invented it or first used it or something like that
