The guys over at InfinitiScene asked RadioActive Motorsports to custom design a super light weight crank pulley for the VK45 engine (FX45 and M45). We stepped up to the challenge and are now looking to see who will be interested in buying one.
Estimated HP gains are in the 5-10 HP range depending on supporting mods. The final design is only 1.5 lbs. That's less than 1/3 the weight of the OE pulley.
I need to get approval from the powers that be prior to starting an official GB, but wanted to see who would be interested. Pricing is at or under $200...
There is NO issue of oil leaks or crank seal wear due to the OE shaft being utilized with our design.
