"The Active Autowerke Signature V10 Pulley kit is a complete bolt on kit engineered using Aircraft Grade Billet 6061 Hard Coat Anodized Aluminum. After months of R&D in house and overseas (various climates & conditions) we concluded that there may be a slight power increase by going smaller than our pulley but the trade off is a chance of making the engine run hotter or possibly overheat, we choose reliability over that extra 1-2 rwhp that we may get from a smaller pulley. Another key element in the development of the Signature Pulley Kit was to retain the “Factory Crank hex Drive Adapter”, this was important to keep this factory feature for its inherent purpose. The pulley kit does not modify factory harmonics or dampening. Stronger side walls were the last key element in choosing our size over a smaller design. The Active Autowerke Signature Pulley Kit yields gains of 12+HP on a completely stock car. This is a complete bolt on system that is easily reversible. A must for the true enthusiast." NOTE: To further achieve additional horsepower gains, one can add the Active Signature high flowing exhaust and experience that F1 sound. Or add the Active performance software. Speak to an Active sales associate on the advantages of these fine power upgrades. Best of all, special pricing is available.
