Nitro Engine's: O.S.SPEED21XZ-B DEBUT!! (1303 Reads)
Posted by admin on Tuesday, September 07, 2010 - 03:58 PM
 

O S Speed

In 2006, Mark Pavidis won the IFMAR Off-Road World Championship using the O.S. SPEED 21VZ-B V-Spec. You may also vividly remember Atsushi Hara’s victory in the 2008 IFMAR Off-Road World Championship with his O.S. SPEED 21VZ-B V-Spec II. For all prospective champions, the O.S. SPEED 21XZ-B now hits the market with a completely new design that surpasses the previous model in every respect.

The all-new champion’s engine.

With the SPEED 21XZ-B, the power you need to win is available at your command. It delivers instant throttle response and powerful torque over the entire rpm range.

The factory-tuned engine further evolves.

Based on the user-friendly features of the MAX 21XZ-B, the SPEED 21XZ-B also includes a tungsten-inserted and silicone-filled crankshaft with DLC coating; a lightweight, low-gravity outer head with many cooling holes; a ceramic ball bearing, and more — all the right ingredients to create champions!

O.S. T-2050SC Mark Pavidis Tuned Pipe With Manifold

This is the O.S. T-2050SC Mark Pavidis World Champion Edition polished one piece tuned pipe with manifold. This is the one piece variety and includes an off-road manifold, which attaches to the tuned pipe using three small springs (included). This pipe is designed specifically for O.S. engines such as the O.S V-Spec engines and is one of the best pipes for those engines providing excellent bottom end and top end performance. Includes tuned pipe, manifold, three small retaining springs, two springs to wrap around the engine crank case and two exhaust gaskets.

Nitro Engine's: OS V.SPEC SPEED (1676 Reads)
Posted by swebb on Saturday, January 20, 2007 - 02:35 PM
 

O S Speed You’ve probably heard all about it, seen some photos and noticed that this engine is the current IFMAR World Champion in 1/8 Buggy (thanks to Mark Pavidis), but we now have exclusive internals photos of this amazing mill.





OS’s latest flagship model is a work of art, with many features reserved for only the finest high-end engines in the world.

The visual similarities to the original V-Spec are all there, but it’s what’s inside that makes this engine special.  First, the V-Spec’s port timing has been modified by OS Japan to produce more mid-range and top-end power.  The sleeve itself, however, looks very “standard” V-Spec, with transfer port “fangs” that help direct fuel/air flow.  Although we haven’t had the chance to time-out the sleeve, the Speed’s exhaust port looks wider and higher-duration than the stock V-Spec as well.  This extra exhaust timing should help the Speed version make more top-end power.
