More Boost and Horsepower is on its way with the new R&D Monster Power Supercharger Impeller Wheel Kits. The R&D engineering staff has been developing a complete line of supercharger impeller wheels that actually deliver the power and boost pressures we promise. Each Monster Impeller wheel will come complete with a statistical data sheet graphing the RPM/boost pressures that the wheel produces, eliminating the mystery behind the supercharger. Stay tuned for complete information. BALANCING INFORMATION: R&D Monster Compressor Wheels for 255 H.P. 4 Tec engines have been precision mass center balanced in the preliminary casting/machining operations process, and precision two plane balanced after the final machining processes. The balance tolerances on the R&D Monster Wheels are held to a much stricter and tighter tolerance over O.E.M. or aftermarket wheels. Your R&D compressor wheel may have small balancing grooves machined in the blade channels of the wheel in some areas. This procedure is part of the mass center balancing process. The small grooves do not in any way impede or hinder the compressor wheels ability to efficiently pump or compress air. The R&D precision two plane balanced compressor wheels will perform perfectly and smoothly at 180,000-200,000 rpms as the wheels have been blueprinted and balanced to stringent turbocharger specifications, even though the wheel will only spin at 46-48,000 rpms in the Rotax engine at 8,000 crankshaft rpms. R&D has gone the extra mile in the balancing process of the Monster Wheels as higher balancing standards will add significantly to the service life and performance of Rotaxs vulnerable and temperamental clutch system. Precision balancing will significantly increase bearing life, promote better clutch performance, extend clutch life through decreased clutch slippage, and increase horsepower performance.
