the trainer for track workouts is not an easy thing..
as Brawlo mentions- you will have to figure out a way to keep the tire from slipping. I don't put out anything like 2000w and i have never had a trainer that did not slip... (i never did the grip tape though)
the other question is fluid vs magnetic resistance.
Brawlo- Are you using a road bike on your Kurt Kinetic?
since the resistance on Fluid trainers goes up with wheel speed- you dont have any control over resistance unless you have a road bike drive train, so you can shift gears..
Magnetic resistance trainers are available with adjustable resistance (kurt kinetic makes a nice one) but they can feel very choppy and may not have the resistance needed for your 2Kw jumps..
