On Friday the 14.12th of December was the first day of our X-Mas duel.

Despite sub-zero temperatures, some performance seekers came to our test bench.

For refreshment, hot coffee with a shot and warm pretzels were available in our workshop

To begin with, we would like to briefly introduce you to the engine that needs to be beaten - the duel class, Vespa Smallframe, max.140ccm, one-piece outlet and sucked in via the motor housing.

The current state of affairs is 28,4HP at 9800U / min, from December 16.12.2010, XNUMX with a 133 gray cast iron Polini, bgm crankshaft, Magic fire exhaust and 35 Keihin PWK Carburetor with Strohspeed intake manifold and Polini membrane.

Among other things, the Strohspeed intake manifold was developed and tested on this engine, from the first prototype made of steel, through the cast samples made of aluminum to the finished intake manifold.

Today's fire magic exhaust also brought its first horsepower to the role on this Polini engine - the first Proto was still a straight pipe and was called Astro1.

We would like to show you some meaningful runs in the duel class:

Mathias Scherer from Ludwig & Scherer, currently with 28,2 HP, also with a Polini gray cast iron cylinder. The rotary valve (!) Is operated by a 38 Keihin PWK fed and currently provided with enough horses by a fire magic.

Jonas from Nettetal should of course not be absent from this campaign. In the Germanscooterforum you can be constantly advancing "Summer-Winter Project" admire.

It also fires a Polini 133 made of gray cast iron. The motor is also equipped with a Polini membrane and is ventilated via a 35 Keihin PWK. With the last changes to the control angles, now 128/196, a lot has happened here too!

In the first attempt with the air filter, the limit of 28,4 HP could not be cracked….

Without the fan ring of the Vespatronic, the output rose to over 30 HP….

... mmhh, then after almost exactly 2 years I have to get the Polini motor out of the corner and put it back on again - or maybe just unscrew the fan ring ;-)

There is still some time until the second day of the duel - but for December 2st. also announced numerous comrades-in-arms whose engines should also be able to exceed the 21.12HP limit ...

It will definitely be exciting.
