These flywheels utilize RPS's patent pending "segmented" heat shield system. Traditional heat shields warp
because of the uneven heat produced by a slipping clutch. Just like a car going
around in a circle, the outside tires go faster than the inside tires, the clutch disc
slides faster around the outside of the flywheel than it does around the inside. The
faster moving outside gets hotter than the inside. Because metal expands more the
hotter it gets, the outside of the heat shield expands more than the inside. Traditional
heat shields are made of one piece metal rings, so when the outside expands more
than the inside, the only thing the shield can do is warp. The RPS Segmented heat
shields are not connected so they can expand and contract without warping. A
warped heat shield causes the clutch to slip, which causes more heat and more
warpage.
RPS Billet Flywheels are dynamically balanced after CNC machining. Other flywheel
manufactures assume that since they CNC their flywheels it comes off the machine
fully balanced. This would be true assuming the density of the aluminum is constant
throughout the part. Unfortunately even the best billet material is not evenly dense
throughout.
RPS Billet Flywheels are also fully rebuildable. List Price is $575
Group Buy price for 5 or less is $525
Over 5 in on the group buy brings the price to $475 Email me @ zwiz@socal.rr.com
