This is unadulterated BS. There are many, many Mazda RX7's and other
rotary powered
cars out there with well over 300,000 miles. 500,000 kilometers. I
see many 25 year old
first gen RX7's on the freeways  of Southern California almost every
day. I saw one
this morning.

I have owned  six rotary powered cars. A new RX2, an RX4 station
wagon, a two rotor Cosmo,
two 2nd gen RX7's and I currently own an RX8. Some with over 300,000
miles. None of them
ever had any problems with apex seals or problems with the chrome
plating.
Some Mazda rotary aircraft applications in gyro copters have over
2000 hours with no troubles.
Rotary engines have been used in aircraft since 1973 with stock
Mazda chrome plated
rotor housings. Further more chrome plated cylinders were specified
in WW II by the US Navy
for all their aircraft engines for salt air corrosion reasons.
Chrome plated cylinders
were also widely used in general aviation air cooled cylinders and
still are.

IMHO the credibility of this company is zero.

Paul Lamar ...No rotor no motor.

Interesting that they offer a re-chroming service.

I think this topic came up before - take a look at rx7club.com and

Here are pics of one JHB failure:

A local fellow described a similar failure.

Cary,

JHB offers several types of Cermet. The company told my friend that Racing
Beat gets their housings done there as well. HMMM?

The details are in the process.
