Rotax twin 583 snowmobile engine using Wiseco's forged pistons, ceramic coated by Swain at a 15 to 1 compression ratio.


Cylinders were ported by Crank Shop, a performance snowmobile shop and has  their twin pipes matched to the porting. Expect to see 8400 rpms with Methanol and nitrous and  300 ft times in the high 3's at 78 mph.Engine has both electric and rope start. You'll appreciate the electric with the high compression. The complete engine build as well as the rest of the ATV is well documented in a 3" notebook. 

   Engine management is  a Motec M600 ECU with options for Lambda control and extra data logging memory . The ignition is an MSD DIS-2 PLUS high output ignition( 560 volts to the coils ) and adds a lot of top end power.. Four matched fuel injectors from Injector Dynamics feed the fuel. Two are located in the Kinsler 46 mm throttle bodies and the other two are machined directly into the lower crankcase.   Fuel pump , regulator and 10 micron filter are also by Kinsler.   Motec has an option of selecting 2 fuel maps with the flip of a switch, so one setting is for methanol  and the other setting is for an" end of the race day"  gasoline purge to prevent methanol corrosion.  The engine has been tuned to run perfectly smooth on gasoline. All that's necessary to change fuels is to drain the fuel using the drain valve  located at the lowest point of the fuel system.

     The unique nitrous system is controlled by the Motec ECU and has a digital solenoid and matching driver that can vary  the nitrous output throughout the run.It is programmed to start at a 30 HP amount and smoothly ramps up to 80 Hp ( 100 hp max ) over 4  seconds and is fully adjustable. The digital solenoid is designed to safely pulse the nitrous eliminating the need for different stages and multiple soleniods. The Motec ECU has been programmed to add corresponding fuel through the case injectors  to match the nitrous needs.

​    An additional high pressure CO2 bottle with regulator maintains exact pressure in the nitrous bottle at 950 lbs which allows consistent  engine performance all the way to a cold , nearly empty bottle. About 8 years ago  I helped Nano Nitrous design this system  for these small 2 lb bottles.

    The frame was built by G T Performance using chrome moly TIG welded tubing.  Another unique feature I designed is my swing arm pivot shaft with is also the jackshaft for the rear sprocket. The front of the swing arm contains high speed bearings , a titanium shaft and the 12 tooth sprocket.

This design keeps the chain at the same tension regardless of the swing arm angle plus it saves weight.

   I have all the receipts  in my notebook  as I used all new components, nothing was purchased used.

  For cost review , I am listing the larger components of the build along with the original purchase price and what these sell for at Ebay prices.

 

  Sell price to be determined after all parts are listed.

Extra injectors machined into crankcase.
