October/ November 2009 Wiseco Performance Products Newsletter

Gen. 3.5 is Here for Dirt Bike Applications!
Add AND subtract fuel in your dirt bike with Wiseco's Gen. 3.5 fuel controller!  The fuel management controller will allow you to fine tune your EFI fuel delivery to maximize the performance of other modifications to your bike, such as high compression pistons, exhaust, intake, or camshafts.  Wiseco is now introducing its new line of fuel controllers, available and ready to ship for the 2009 Honda CRF450R, Kawasaki KX450F, and Suzuki RM-Z 450 dirt bikes.  These controllers are simple to use, with no dyno or computer needed!  With the touch of a button,  you can easily adjust three basic zones of operation, similar to a carburetor- a "pilot jet" zone to set your idle and cruise; a "needle jet" zone for acceleration; and a "main jet" zone for heavy loading and wide open throttle. 

To find exact model information, visit and use our year, make, and model search. Wiseco fuel controllers retail $249.95 to $299.98.  Wiseco also offers versions for street bikes, V-Twin, and ATV models.  See the links below for details.  Visit to see all our products!

The Chill of Snow Season is Here!
You feel that cold chill in the air and tune into football games all weekend.  You know what that means?  It is almost time to bring out the snowmobile!  You'll want to give your sled some renewed power this season.  Let Wiseco bring life back into your snowmobile season.  We've brought out some new models and even skirt coated a few older parts to make them last longer than ever!   
First up is the new Arctic Cat F1000, M1000, and Crossfire 1000 EFI piston kits.  These pistons are ready go with our ArmorGlide™ skirt coating!  This is a permanent coating that allows the piston to be fitted tighter within the bore.  What does that mean?  Minimized friction, maximized horsepower, and improved wear resistance!  Dedicated forgings give you superior strength with electra-coating to eliminate ring and piston pin scuffing.  Get the kit for only $394.41- that includes pistons and the top end gasket!  Check out detailed information here.
We've brought you a new Ski Doo piston kit too!  These pistons fit the 793 engine type ranging from 2001 to 2007, depending on the model.  Just to name a few- the MXZ800, Legend GT SE 800, Summit 800, and MXZ Blizzard 800.  We've made these pistons light weight so you feel less vibration and improved throttle response.  Of course we've built them from dedicated forgings, but these also have dedicated rings to maximize compression.  Get our kit, complete with top end gasket kit for only $373.14!  Click here for more information.
Our last featured piston is an upgraded version to give you the best possible performance.  Get your Yamaha Nytro, Rage, Vector, or Venture ready for riding.  We've coated these in our in-house skirt coating facility with our ArmorGlide™ skirt coating.  Choose from a stock 9.5:1 or 12.5:1 high compression ratio, available in a 79mm and 82mm bore size.  The kits retail from $363.40 to $483.70, so get yours before the snow falls.  Find out more information here.

Wiseco's GM 2.0 Piston Kits-- Perfect for the Soltice, GXP, and other GM Applications

Technical Corner
In each newsletter, we will be answering commonly asked technical questions that come up during a rebuild. 
Q: What are the other factors to consider when maximum horsepower is the goal?
A: Compression ratio and Dome/Dish volume determine combustion efficiency and resistance to detonation. Detonation can and will destroy any piston in short order. Lean conditions will melt any piston as any aluminum alloy melts within a few degrees of each other. Most of a piston's heat is dissipated through its contact with the cylinder wall and oil splash. Very short pistons and excessive clearance will melt a piston sooner. Static compression varies more than most people would believe. A piston running .020 down in the cylinder at TDC as opposed to "zero-deck" on a 64cc combustion chamber headed 350 Chevy changes the compression ratio from 10.25:1 to 9.8:1.
People running compression ratios higher than 14:1 are not making more power if it means an increase in dome rise. More dome rise only hurts combustion efficiency which will lose more power than is gained by increasing compression. The current trend in Pro Stock, and others with big-budgets for engine development is to make the combustion chamber smaller and go to 12, 14, or 18 degree heads to make that happen. They are going for the shortest dome rise that gives them the compression they are looking for. The trend is to also use a bigger bore with a shorter stroke to put an engine at its best power potential for a given cubic-inch limit. One point to remember is a pro engine builder will never trade ring-seal for cubic inches from making a cylinder wall too thin.
