Turbo upgrade mods for 1100 or 998

Arctic Cat Z1 and ProCross 1100 Turbo, Cat/Yam 998 Compressor Turbo Upgrade

Our compressor wheel upgrade for the stock turbo features a larger, billet compressor wheel that is installed and then rebalanced on the stock Arctic Cat CHRA. The compressor cover is modified and ported to accept the new billet compressor wheel. Tests show a significant gain in airflow over the stock compressor wheel and horsepower gains throughout the powerband and above. 

It can be ran in the trail as an upgrade, or used as a full race turbo. 

If the CHRA needs to be rebuilt, we do have that as an option for additional cost. The bearings will be an upgraded ceramic bearing and the seals are also an upgraded version.

**A good working turbo core is needed when purchasing just the compressor upgrade.**
