coated bearings..

are they worth it...?? jjust looking to squeeze all i can from this na motor...

Clevite TriArmor Moly/Graphite Coated Race Bearings
TriMetal adds a new layer! The industry's first and only moly/graphite treated bearings. This sophisticated blend, a low friction PTFE polymer base, offers extraordinary protection and lubricity. A thin uniform coating reduces friction and drag, resulting in increased horsepower. Protection during start-up. Embedability to resist damage from debris. Ability to withstand extreme temperatures and pressures. Conformability for distressed or imperfect surfaces. Extraordinary strength and durability. Increased bearing life in performance and race applications.

and the cam bearings from dura bond..

Dura-Bond Coated Cam Bearings
Fluoropolymer composite coated. This dry lubricant actually penetrates the surface where it has been applied. The primary advantage is that bearings with this coating retain engine oil on the surface, even under extreme heat and pressure conditions. Being a lubricant itself, the coating provides secondary (back-up) lubrication in the event that momentary oil starvation occurs.

I believe if you have the opportunity to take advantage of any new technology
when it comes to films and lubrication.. you should be all over it.
Millions are spent researching and developing these products and they do work..

Find a dyno sheet - depending on the price there may be better places to spend money my .02

Coated bearings are good insurance, but obviously not absolutely necessary. :cool4:

They are nice and exspensive, check out Z Alt motor oil, it has the molydenum additives and they also use ptfe polymers to keep the moly suspended in the oil. In the past keeping the moly from settling to the bottom was the problem but these guys have found a way to keep it suspended, then you can basicly have it on all moving parts instead of just the bearings. just my thought

Good tip!

i use the clevite coated bearings. to me the little extra hp and a little more insurance is worth the $150 extra. when i dropped a valve this last time, broke the cylinder wall, bent the rod and drove it back to the trailer and into the garage, the crank and cam was unhurt and i believe it was the coated bearing that kept the journals from being scathed.

I use them...
