<div class='quotetop'>QUOTE (jazkat @ Mar 6 2009, 12:37 AM) <{POST_SNAPBACK}><div class='quotemain'>this was 07 so i guess 08/09 still uses the same firing order
Firing up the GP7 on the rollers produced a glorious sound from the twin 2-into-1 exhausts. The "screamer"-firing-order engine used this year has allowed Ducati to revert to these, in contrast to the four separate megaphones required by the old "Twin Pulse" 990. The lumpy, offbeat, 3000-rpm idle speed is deliberately set high to help offset engine braking when you close the ride-by-wire throttle entering a turn.
the Ducati accelerates very hard from around 11,000 rpm onwards. There's a meaty spread of midrange power as it builds furiously toward the 19,000-rpm rev limiter dialed in for this press test (20,000-plus rpm in race guise has been rumored).
The high idle i can understand.Of what i can hear from the broadcasts all makes seems to have that.A lot of acceleration starting at about 11000 i have read about too from some journalist testing a downtuned GP7 or something,although maybe that has been developed to start earlier now.
But,i always thought most MotoGP engines were divided into 4 separate cylinders doing a different job.
4 engines so to speak.No matter how many exhaust pipes they end up in.Maybe i'm totally wrong.Don't know.
