...<BR>><BR>> I've heard that all the Boca's except the Econo-Power
bearings(including<BR>the<BR>> High Speed and the Ceramic) use a retainer
(phenolic?) that will degrade<BR>in<BR>> the presence on nitromethane and
eventually fails.<BR>><BR>> Also that the hi-speed bearings have no
advantage over the Econo Power<BR>ones<BR>> when RPM is less than
25000...<BR>><BR>> Sure wish they made ceramic bearings with standard
