Print | Back December 15, 2010 Boost for the Doo Turbo Performance's Ski-Doo Alternatives For a growing number of backcountry riders,  boost is where the party’s at. But fuel injection has  been a limiting factor. Or so you thought. Turbo Performance, a performance shop out of  Roy, UT, builds specialized turbo kits for Ski-Doo  sleds. Turbo Performance has build kits for the  carbureted 800 twin for years, and this past season  we spent some time on the snow with them with  a 2009 Summit XP 800 turbo and a 1200 XR four- stroke turbo.  We met up at a remote location in the southern  end of Wyoming’s Salt River range on a cold day  dotted with heaps of fresh, dry powder. Although it  was 25 degrees below when we left the parking lot,  the temps climbed as quickly as we did. After gaining  a thousand feet of elevation, the temps were in  the teens with sun shining on the untracked powder.  It was a perfect day to see how these two Ski-Doo  mods would rip. Josh Kennedy and Bryce Kendrick spent a little  time dialing the two sleds in for the conditions. It  doesn’t take much—the 800 XP turbo and 1200 XR  four-stroke turbo are pretty easy to tune and make  minor adjustments. We hit several good climbing  spots and played around in the trees. The snow was  perfect in the trees for challenging the power of a  stock sled. The turbo Summit XP had no problem  going up and around any part of the  mountain.  The Summit XP is a natural in the backcountry,  and the Turbo Performance setup  added to its mountain abilities. Turbo  Performance added an Aerocharger 66  turbo with a chrome charge tube and  exhaust, plug and play electronics, boost  and fuel pressure gauges, clutch components,  a fuel pump and rising fuel pressure  regulator, turbo-spec reeds, custom  exhaust valve parts and silicone hoses  with constant-tension clamps.  For chassis modifications, the XP runs  a 163-inch Camoplast Challenger with  2.5-inch lugs, a Shockwave secondary  clutch with Turbo Performance’s own  setup and gearing, and R&M Lightning  Products’ vents.  The 1200XR was too much for tree riding,  though Kennedy muscled it around  anyway. It was built for a customer in  western Canada, where the hills are  long, straight and open. It has a Turbo  Performance Stage 1 kit with a 174-inch  track with 2.5-inch lugs. The sled is an  absolute school bus right down to the  color, but it hauls up the side of a mountain  like a Ferrari on the Autobahn.  The huge track wraps around an  EZ-Ryde suspension and it all sits beneath  a Van Amburg custom tunnel. A Rage  IV primary and Shockwave secondary  clutch handle the power delivery. Turbo  Performance has its own clutching and  gearing setups for these builds. Turbo Performance uses R&M  Lightning Products’ vent kits to keep the  big four-stroke motor cool. The Stage 1 turbo kit puts out 260  horsepower at 12 pounds of boost. It  uses an Aerocharger 66 turbo, external  fuel pump, fuel regulator and an Attitude  fuel controller. The kit comes with the  charge tube, intercooler, constant-tension  clamps, boost and fuel pressure gauges,  exhaust system, boost line and all necessary  hardware.  See more of Turbo Performance’s creations  at www.turboboyz.com. © 2013 SnoWest® Magazine http://www.snowest.com
