Briggs & Stratton 206 Engine Poised to Improve 120-Class Racing


(9/18/2012)

Displaying at the Sno Baron’s Hay Days this year was the iconic engine manufacturer Briggs & Stratton. The guy in the photo is David Klaus, Briggs race engine director.

Specifically, the Milwaukee, Wis., company was showing its 206 Sealed Crate engine, can make modified 120-class snowmobile racing WAY more affordable and fair.

Briggs & Stratton 206 Race Engine

The 206 engine isn’t actually new. It’s based on an engine with 12 years of racing history, and has been used in 206-form for cart racing since 2009. But 2013 marks its debut in snowmobile competition, as it’s been approved for use in USSA, MMSRA, KC Pro West and by ISR. It will be used in two newly-named classes, Semi Pro & Pro.

So what is it?

 

It’s a complete engine that bolts into any of current crop of 120-class snowmobiles, including all years of the Arctic Cat 120 (see below).

Salient feature #1 of the 206 is that it’s a high-performance mill compared to any stock OE 120 engine. Whereas the stock 120 engines produce about 3.75-hp, the 206 produces about 8.8-hp with 11-ft.-lbs. of torque. That’s on par with many of the mod-class 120 engines, but with a huge difference:

The 206 is a spec engine with a sealed crankcase, spec exhaust pipe and 6100 rpm rev-limiter. This is important because is seriously “levels the playing field” of mod-class 120 racing because all 206 engines are identical (and if a seal is broken, it’s visible). This not only prevents the winner-by-virtue-of-dollars-spent scenario, it also eliminates the prospect of cheating the engine rules.

Just as important, the upshot of this level playing field is that the cost to go mod-class racing just went down by several Ben Franklins. Cost for a complete engine with spec pipe/muffler, throttle cable, recoil and paperwork is about $675 U.S.

Furthermore, Briggs offers four different length carburetor slide options (shown above) for the 206, with a corresponding increase in performance with each. This provides a simple, inexpensive “ladder” for increased racing performance. Each slide is also color-coded for easy tech.

A few things to note about the 206:

*It’s not designed to replace the ultra-modified Champ class of 120 racing. Nope, Champ remains for those who like to seriously dent their wallet.

*To achieve repeatable performance consistency for all 206 engines, Briggs & Stratton utilizes factory tools and dies; uses controlled piston pop-up for consistent compression; utilizes a digital ignition with built-in rev limiter; assembles these engines in Milwaukee using custom hologram seals; then tests each engine before shipping to confirm its “fair” performance

*With simple maintenance, an engine will last for more than one season before the need to rebuild. When it’s time for a rebuild, a complete factory-sealed short block is available for less than $300, which is less than a typical rebuild.

*Testing of the 206 engine has proven its consistency, ease and incremental increases in performace for each carburetor slide.

Anything that can help in the expence department is a plus for any type of racing.
Dave needs to get an "at a boy" award for helping promote racing with the little league racers and bringing new faces to the sport!

Wish he would have had something like this 10 years ago when my kid oval ice raced.

I never could figure out how someone could take a new 120 kids snowmobile they bought for around $2,000, let the kids race it all winter, and then ask around $7,000 for it at the end of the season.
And then the racing associations say they want to keep racing inexpensive, so they can get more competitors. "I guess some parents will do anything for their kids to win a plaque!"

Hey John Z.

The race sleds that you are refering to were probably the 120 Champ sleds and yes, some were in that price range or more.

Any sled that was a dominate one and for sale at the end of the season always brought big bucks.

RaceKid...like Tom Rowland of Thomas Sno-Sports told me...anyone can be a millionaire after racing one season...you just have to start with a BILLION!
