Description


"The Polini 207 convinces by its enormous torque from the lower and middle speed range. It develops its best performance in almost the same speed range as the original engine with some reserves upwards. This makes it ideal for breathing more life into an original one without any further modifications.

We recommend an exhaust based on the original, e.g. BGM BigBox or SIP Road.
The ideal cylinder head is the Polini''s own head, which is also included in the 210cc aluminium kits.
Its significantly larger cooling fin surface helps to keep the Polini thermally in check. With a correspondingly careful jetting, the Polni 207cc can also be driven out of the box (without Voddoo) on the motorway at full throttle. He reacts very gratefully to a revision of the intake and the crankshaft, as described in the Polini manual supplied with the car.

However, a larger carburettor such as a Keihin PWK28, Mikuni TMX27/30 or Dell''Orto PHBH28/30 is easier and safer to tune. The resulting longer suction path additionally provides a plus of extra steam from the cellar.

As basic adjustment for a SI24/24 or SI26/26 we recommend:
Main air nozzle: 160, mixing tube BE3 or BE2 (the latter is more greasy), skin nozzle 125-132. Air vent without bores Secondary nozzle 55-58-60/160 or 52/140 well chosen. The original 8492.4 or the 8492.1 or 8492.5 of the T5 models can be used as a slider or for a greasing in the middle of the slider. The ignition should be set to approx. 18-19°.

As basic adjustment for a PHBH 30 we recommend:
Needle: X2, Mixing tube: AV264, Slide: 30, Main nozzle: 125-145 (depending on exhaust and/or rotary slide/diaphragm inlet), Secondary nozzle: 55-60.

TIP: The Polini runs even better with an ignition module of e.g. Kytronik. Here the motor can be driven with a full 25° F.S.T. on curve 2. The result is a high torque with improved durability under continuous load.


If you want to get more power out of the Polini, a long-stroke crankshaft is the perfect solution.
Then a performance of over 20PS/25NM can also be achieved with a so-called box exhaust.

Conclusion: The Polini is the tractor among the conversion cylinders. Its full torque and the good pull predestine this cylinder for the long tour as well as for the next traffic light duel!
