Holeshot 4-1 Comp 1 Header System - Dyno Charts

Yamaha FZ1 (through 2005)

NOTE: These are true numbers measured on Dales in-house Dynojet 250 I dyno, with "Win Pep 7" Program, STD mode, Smoothing 5

The Holeshot compound is now at aprox. 4500 feet above sea level here in NV, and is down about 3 to 5 HP from our old location in CA. Dale uses his dyno as a measuring tool for development and testing only.

Be aware that different dynocharts, dyno operators, conditions and bikes can vary 3-8 HP, so this should only be used as a reference for before and after results.
