Rick - I agree that the Bourdon tube gauges with direct connection by
suitably sized tubing make me feel better than the electric versions. The
stock gauges supplied by such as Smiths normally have way too small capillary
tube (I like size 3 or 4 braided Teflon hose) to register quickly enough - by
the time you see a pressure drop you have already been without oil for enough
time, perhaps in a long curve, to do damage.
And I have to ask what your 7700 rpm 100 psi sports car is. It sounds too
much like my Lamborghini in terms of rpm and pressure to be a coincidence,
but the Islero has an electric, not mechanical gauge - I just spent some time
finding a 10 Bar gauge as a replacement.
