Arctic Cat

compare well broken in demo sled with Billy Howards 50 mile production sled

Stock engine stock pipe, SSI pipemod, D&D, SW, BMP, Jaws and higher HP AA ported w Jaws pipe

5 hours light load operation to break in the ECU, sled from Arctic Adventures’ Tom Ferry

Stock vs Speedwerx pipe and Ypipe, Jaws pipe and Y pipe, SSI pipe mod

Stock vs full Jaws exhaust vs Jaws exhaust with stock muffler, all with optimized fuel and timing curves

compare new ZR8000 to the AmSnow/ DTR Shootout 800+cc pre-breakin engines

All “big bores” are not created equally–port shapes and timing are critical as this five session evaluation indicates

A to B, .072 squish vs. .039 squish with identical 14/1 comp ratio, fuel flow and timing optimized for both. Thanks to Kevin Cameron for this test!

Different than the preproduction Sidewinder demo sled, we explain why and show the difference in fuel flow tuning makes

D&D Y pipe, stock muffler inlet restrictors, timing adjustments, add up to lots of HP for $300

Dyno tune session with all the BMP big bore options, perfect cold weather PCV tune

incredible HP– compare RK Tek big bore with perfect tuning, stock vs D&D single pipe

compare stock to BMP, D&D, SLP, and Speedwerx

SLP Crossfire/ M800 pipe tested, new BMP Y pipe compared to stock and D&D single

compare Ypipes, single pipes to see who has best torque, best HP on pump gas

Max power on pump gas with large intercooler, high flow exhaust, and ECU reprogramming

tested stock, with PCV leaned mixture, D&D Ypipe, and D&D single pipe

baseline testing from 100 degree coolant temp, through 130+ degree coolant temp
