Testastretta Engine Differences?

Discussion in 'Technical Help' started by Nelson, May 13, 2014.

  1. I was nosing around on ebay last night and the Ducati UK website at the various incarnations of the Testastretta engines. (feck all on telly and it was raining)

    I'm interested to know the differences;
    For example a 1098 Superbike engine has slightly more power than a 1098 Streetfighter engine.
    Why? IS this due to different cams/valves or throttle bodies/fueling/?
    Also a 1200 multi is way down on an 1198 Superbike?

    A multi engine looks a good option for a build IMO, Testa II with a nice wet clutch, until you see it's ~150hp.

    Cheers

  2. Cams, compression ratios (different pistons?), fueling (ECU), gearing (gearbox ratios?)

  3. No cheeky 1198 to be had then...? ;)

  4. Power wise I thought the 1098SF v the 1098 was mainly down to air box limitations and not cams etc unlike say the 848SF and 848 where the 848SF is a TS11 engine..

    What's up Nelson you board again mate? lol

  6. Lowered compression to eek out service intervals?

    The 1098 is all ohlined up now, I have also got me a new R frame with a DUC plate and V5 which I may be getting painted and swapping over this winter. It has an annoying farting/fuelling issue at the mo that I'm trying to sort!

    The 848 evo engined build is my track bike, been to Spain in Jan and was in Wales last weekend.
    One was scorchio, the other was wet and windy...:rolleyes:

  10. Good enough for Miss Daisy... :Chicken::Nailbiting:

    You still have the blingest 848 in all the land?

  11. Mainly the cams. The Multi version has cams with very limited overlap (nominally 11 degrees), making it soft and tractable at low revs, while the superbike version has vastly more overlap - hence more power at the top end, but a bit awkward in towns. Maybe one day we'll get variable valve timing, and the best of both worlds, but not so far.

  12. Love the rearsets. Shame about the seat unit. Put an 916 one on you heathen barbarian. :Wideyed::Sorry:

  14. You're not alone. I spend way too much time on that site myself.

    Last night I learned that all 2014 Panigales come with ABS as standard now. I was wondering about that given that the 899 has ABS, but it was previously an option on the 1199, which seemed like an anomaly.
