I gruppi termici Polini sono il vero cuore del motore e sono indispensabili per ottenere massima potenza, maggiore accelerazione, prestazioni altamente performanti. Cilindri in lega leggera termoresistente a bassissimo coefficiente di attrito o in ghisa grafitica lamellare
caratterizzata dalla massima resistenza
all’abrasione. Travaseria progettata per un consistente incremento della erogazione della potenza. Diagramma specifico per ottimizzare coppia ai bassi regimi e potenza massima. Prove in pista con impiego di avanzati sistemi di telemetria.
Polini cylinder kits are the engine’s real heart and they are essential in order to obtain maximum power, better acceleration, high performances. Cylinders are realized in light heat-resistant alloy with low friction coefficient
or in foliated graphitic cast iron
characterised by exceptional resistance to abrasion. The transfer ports are developed to achieve a great power output increase. Specific diagram to optimise the torque at low speed and maximum power. Tests on tracks with advanced range-finding systems under all conditions and on all tracks.
