    Horsepower to wheels calculator

    http://www.mk5cortinaestate.co.uk/calculator4.php Just a neat little gizmo. I know its not going to be super accurate, but gives you a quick reference point. 140 hp vmax = 113 hp at the wheels..... so its not really far off.

    Looking for List of Highest HP Bikes by Year

    Hi, Just out of curiosity I'm wondering what motorcycles have held the title of "most powerful Production bike in the world" throughout the course of history. I've managed to find plenty of lists of record speed holders but nothing about power/torque/fun. Does anyone know of such a...

    Horsepower improvement with needle shim

    I know that there are several people on this forum that have shimmed the needles in their carbs. Does anyone know how much of a horsepower increase that they had? For instance putting the bike on the dyno before and after it was done? Or has it just helped the drivability? I have an 07 (with...

    Horsepower

    I read that up to 2001 all Vmaxes where about 102 HP, and the after that up to the new gen one they were 145 HP! And that all the difference are the carburetors! Is this true? And if it is, can a carburetor from a recent Vmax, say 2006, fit into a 2001 one?

    VMax Horsepower

    When I bouight my 95, I was told that it produced 140 HP...this is by the PO. I've looked it up online, several diff sights, several diff answers...anywhere from 100 to 140. I considered that a possible reason for this diff could be crank verses rear wheel, however, I would not think the bike...

    Mystery of the Missing Horsepower on a Dyno????

    I couldn't decide where to put this so I chose a General Forum. It involves my clutch, a dyno run and the mystery of about 20 missing Horse Power... It warmed up a little here in Not so Sunny Florida. I took Mary and we went for a short ride tonight. About 10 minutes into it, I jumped on the...

    More horsepower than a Humvee!

    I'm watching a Military Channel show on the Humvee and they claim 190 horsepower from the deisel engine, less than the "heavy" 2009 Vmax! I know the Humvee's probably got a couple dozen times the torque, but that's still an amazing comparison. I'm going to hop on the bike now, can't resist.

    Horsepower Gains from Stage 7?

    Is this a mod worth doing? I have a '99 with Supertrapp exhaust and stay pretty much at sea level. If it is worth doing how much horsepoer can be gained? NOTE - I understand you do NOT want to drill slides, change springs, or change air jets (unless you get a stumble).
