Make, Model & Year: 2011 Yamaha Nytro XTX 144 Push-T
Fondly known as: Half Track
Time spent: 90
Sled cost: 7100.00
Money spent: 6000
Engine: Stock 4 stroke Yamaha 3 cylinder 1049cc motor. In stock form, this is a 130 HP sled.
Intake: Push turbo mounted in the rear of the sled as part of the tunnel. Air intake is where the exhaust tail pipe use to be. The mounting location helps balance out the sled. Your are also removing the stock airbox off the front of the motor. No inner-cooler is need because the turbo charge tube (intake) is cooled in the tunnel with snow. This includes a power commander to program Air/fuel.
Exhaust: Exhaust mounted right off the turbo and pointed towards the front of sled in the tunnel. HP is about 190 at 7 lbs of boost. About 210 HP at 9 lbs of boost. Exhaust is fairly quite but sounds pretty mean.
Drivetrain: Using a stock Yamaha clutch with dalton weighted arms and higher rated primary spring along with higher twist on the secondary. Helix is multi angle; 39-53. Running a Gates belt. Gearing is up 1 tooth on top. Track is a 1.22 Ice Attack pre-studded 144 inch. Also added extrovert drivers.
Tunnel/Chassis Modifications: I had to modify the tunnel to support the turbo. Add tunnel enforcement brackets on running boards. Aftermarket bumpers on both ends. Added OFT steering riser kit and 10 gallon gas tank.
Suspension: Added Fox Float X shocks, a-arm protectors, powder-pro skis with dully runners. Added much larger torsion springs and dupont slides.
Brakes: Stock brakes but added bradded line.
Finish - Paint: Change color to Orange hood and supporting Yamaha Nytro orange graphics and windshield. Polished the aluminum tunnel.
Accessories: Added AFR and digital boost gauges to support the turbo. Fog light was added to help see when the skis are off the ground. Accessory bag on rear seat holds your hat, manual boost controller and other items (Torco octane booster).
