Joe@Trinity? He's probably not the only, but you need to remember he was rocking a VF620, RPi Catless X-Pipe & a 91/109 octane blend
(this gave him the last 20 WHP to bump him over 600 WHP, not an upgraded pulley).
The VF650 (different pulley/tune & requires 93 octane) with a Completely Catless Exhaust can probably put down 590/600 WHP easily.
