    Ended the 2011 season in style -- joined the 90mph club!

    Yesterday was my last day on the water and I was on a mission: join the 90mph club. I have been running a consistent 88mph top speed all season and I suspected there could be more to be gained with a very aggressive MoTeC calibration.

    To be honnest, I waited until the end of the season before attempting to break the 90mph barrier as I did not want to fry my engine and trash my season. Well, patience has paid off and with a few advanced tuning strategies, I was able to increase power output just enough to hit 90.0mph flat on my FZS. I feel this is very good as this top speed was achieved with a supercharger and only 221kpa boost on a ET18 wheel on premium pump gas. That being said, the overall calibration on the MoTeC ECU was on the very edge of detonation as recorded by the closed loop kock system used during the final testing. It took me 4 runs to get to 90mph, each time gaining speed.

    Thanks to Pete at MoTeC who has been patient all summer waiting for SKM results from me... and who gave me just what I wanted last week.... info on the lambda compensation table (here you go Pete, now you know what I was up to....)

    All in all, a great season for me with over 68 hours of run time and only 1 clutch to replace as a "maintenance" item.

    Details about how I made this happen to follow this week in the MoTeC support forum.

    Congrats on the speed.. 90 is fast, for sure..
    What is your water temp there now?
    Also, your kpa at 221 is low for 8800 rpms compared to my et18 wheel...
    Just checked my vipec files and at 8800 i have 240-242 kpa of boost..
    At 8400 rpms i had 221 kpa boost last summer on a completely stock engine..

    Lower boost isn't a bad thing. Boost is just a measurement of restriction to flow. So with the same wheel, turning the same RPM, the ski with the lower boost number is making more HP, because it's processing the air more efficiently.

    Congrats Martin! Very nice work. Looks like it really helps to have closed loop knock sensing. 90 on an ET 18 pound wheel, on pump gas, is AWESOME! Your pump must also be working very well. I've seen others with even more boost who can barely hit 90.
