My tach is marked around the typical 6500 for these "consumer" 5 
cylinder cars.  However, my fuel pump relay seems to be "special" in 
that it has yet to invoke the over-rev shutoff.

I have bounced it off 7000 a few times, though I try not to do it under 
load - I'd hate to discover the point of no return!  It sounds good up 
there, though, and when it happens on the road it still seems to be 
happily pulling away.

This is a fairly stock NG in an '89 90Q.  About 250,000 miles or so, 
some 20v exhaust pipes (60 mm vs 55 mm), not much else other than being 
kept clean and happy.  Oh yes, I also installed one of those Hitachi 
coils to replace the Bosch one it came with.  I thought they were prettier.

Anyway, I think that even stock this engine will rev til it blows up. 
How could the cam "affect" it, except to increase power or torque up 
there?  The FPR, as long as it is still working right, won't allow the 
engine past its rev limiter anyway.
