Each 872 Etec customer build is designed for the specific application and desired use, We have at this time 12 different compression ratios available from pump fuel to blends for all elevations. All are machined and developed in house.
We are so specialized in this package that we have now developed different cylinder porting parameters for both low and high elevations to extract the most horsepower and torque out of this superior product line for each specific requested customer 872 build.
All cylinder bores are deck plate simulated honed to correct for small amount of distortion done to cyl bore when head and bolts are installed and also honed to our exact final specs with our in house Diamond honing equipment!
Cylinder head ratios can be updated as needed for the 872 Etec builds, example sled being sold or moved to a different elevation or application, These changes are done by us with our CNC equipment or substituted with another cylinder head. We document all 872 builds as per all specs, build date, orig customer and all parameters done to provide customers with service in the future
Our new developed 872 Y-Pipe and PCV Programmer are some major upgrades for the TMS 872 ETEC that we have now available for even more performance. We have many fuel maps for the PCV that we have designed and tested over the past 3 seasons before releasing for sale. Call for details and pricing.

DEALER NETWORK NEWS:
We are proud to announce that there are 100 Ski Doo/BRP dealers that are installing are line of performance products, Along with 15 independent performance shops.
They range from Eastern US states through out the western mountain states and our friends in Alberta and
British Columbia, Saskatchewan, Alaska, Sweden.
They have all installed our highly successful 872R BB and 872 Etec products, Many will have a demo 872 available for test rides also, This has proven to be the best way for customers to see and try one out for themselves!
Some of the competition is still speculating on what will work and what will not on this vehicle, Making many claims and attacks on our company and proven line of products! This continues daily from specific claimed
builders that attempt to copy and post unrealistic claims against our superior line of products! Choose your Ski Doo engine builder wisely, Some will consist of just a two car garage with nothing more than a workbench and have a guy up the street do some magic porting? and fabricate Dyno numbers as they have never seen one with many claims and false information being offered on a keyboard! Some even go so far as advertising racing! A win at a county fair does not qualify for bragging rites as far as sanctioned race wins go! We continue to convert the 880 and 860 from others that simply do not perform into the TMS 872 for both the R and Etec engines all season long.
This great product makes 186-190 plus Horsepower with a huge torque band on our in house State of the art Super Flow 901 Engine Dyno Facility! We put our exclusive 872 builds through some of the toughest Dyno runs possible with our computer controlled and designed run programs ranging from break in cycles to 30 minute simulated real time runs, Nothing gets by with a easy quick dyno run here!!
We have kits available for pump fuel to race fuel blends for even more performance!
And yes these will run with and go places that the fading turbo market sleds will not ! Many of our customers have sold their unreliable turbo sleds and bought this product!
* Our continued development of this engine package with our new piston design has produced the smoothest performing Big Bore available which also helps produce additional horsepower with our product! (BRP missed the dynamic balance on this engine in stock form). First thing customers notice is handlebars do not shake as in stock form, Silky smooth from idle-7950 RPM!
Our race inspired cylinder porting designs are developed with countless hours of R&D utilizing the finest tools available to provide the highest available horsepower and torque that these Rotax engines are capable of producing while maintaining the proven reliability that our products have to offer.
