Product Details

Terra Alps Racing Ski doo 800cc billet heads make 5+hp at 8100 rpm and 10+ hp at 7000rpm. Thats awesome power for the cost of a billet head. Terra Alps is always designing and testing to build the best billet heads with proper cooling system and dome design not to cause detonation like other poor head designs on the market.

Gain HP and acceleration when attacking an hill or boondocking in the backcountry.

Our billit heads have interchangable domes for pump gas, race or turbo applications, or when upgrading to our bigbore kits just order the domes that fit in the billet head cover.

 

Billet heads with interchangable domes $449 cdn.

 

Colours - Black, Blue, Orange/Copper, or Raw aluminum.

15-1, 14-1, 13.5-1, 12.5-1 or custom turbo application compression ratios.

 

Don't think all heads are the same, all the heads we have seen from other manufactures have very poor cooling passages where the cylinder has inconsistant tempertures due to the coolant flow thru the head and cylinder. On alot of heads they don't have the coolant velocity to flow thru the heads so the coolant flows slow and doesn't pull the heat away from the domes causing hot spots and detonation. Don't settle for less.
