To all the Kraftwerks equipped S2000s out there,we have made a ribbed belt conversion to the Kraftwerks S2000 Kit.On trackthe Rotrex blower has been known to seized. The current cogged belt system is so strong, that when the blower locks up the beltwill not break causingthe engine to stop abruptly. Sincethe blower is married to the crankshaft via belt, this can damageyour engine from the lack of oil pressure. We decided to make an 8 ribbed belt system to ensure no boost slippage, but have more of a fail safe in the event if the blower failed. The ribbed belt will break first keepingyou motor alive. This kit includes: 1 Serpentine Belt,4 idle pulleys, 1 Crank pulley, 1 Supercharger pulley. Pulley sizes available in 100mm and 90mm for the Supercharger. Recommended Ap1 use 100mm, Ap2 90mm. Replacement belts can also be purchased separately.

Notes: This kit fits for both 20mm / 30mm KW belt kits and replaces all the pulleys to a 8 ribbed belt. 20mm belt kit customers will need to purchase misalignment bushings. Bushings are sold separately for 20mm Belt KW kits. Link listing:https://balladesports.com/collections/supercharger/products/ballade-sports-s2000-kraftwerks-sc-kit-ribbed-belt-bushing-kit
