Note! I built both of these packages with high reliability in mind with maximum power at a relatively low rpm range intentionally. They basically run like a stock bike with a whole bunch more power.
For a few of you hot rodders that crave more! Simply installing a GSX-R exhaust cam and Mikuni 36mm to 38mm flatslide smooth bore carbs should get another 8-13 hp. But the overall drivability is the best with the above combination and original 36mm CV carbs.

Note: these are true numbers off Dale's in-house dyno. The Holeshot compound is about 200 feet above sea level and the dyno room stays a constant temperature between 70-80° F. The above results were also achieved with Dale's tuning, which is a bonus.

Be aware that dynos, dyno operators, conditions and bikes can vary 3-4 hp, so this should only be used as a reference.
