Depends on the dyno.
2000 R1
Full system Ti Arata
BMC air filter
Factory Pro 59mm Velocity Stacks (i.e. long)
Rejet done by Dynoverks
+4 Ignition Advancer
~143rwhp according to dynoverks (Boronia)
~153rwhp on a run once on a dyno dynamics dynamometer
At the track it'll match a stock or lightly modified 2004 Fireblade down the straight, but I'm also a fairly heavy guy. I know that the long stacks aren't best for peak HP, but I really wanted the engine to behave more like a V2 with a smooth flat torque curve, rather than be peaky, and this is pretty much what I asked Dynoverks to achieve with it when tuning it. The bike has no real power rush, just a strong push everywhere that builds smoothly.
According to dynoverks, rwhp was at or above 140rwhp between 9800-11200rpm, so it has a really broad peak power plateau, and that's exactly the way I wanted it. Allows you to either short-shift, or hold a gear, and the bike doesn't really care. The tradeoff came from <3000rpm where fueling is a total pig, and the bike will chug horribly if it drops below that, requiring a steady throttle and riding the clutch to get off the line smoothly and quickly.
