<VV> RE: Ed's strange turbo behavior

[Andy Clark]

Well, just to chime in here, my 180 Cord will pump 10PSI+ (that's PSI not
inches of Hg) at about 4000RPM WOT. I don't know what max pressure it'll
produce, because the gauge only reads that high. 10PSI is, what, about 20in
Hg? (Too tired tonight to do the math).

So, at 70mph, Ed Lang's turbo is still pulling that much vacuum? Perhaps he
should use an inboard gauge (sorry about that).

between 20 and 26 lbs. pressure. So much, in fact, that it's pushed the tube
carrying the boost off its mountings. He has measured, not with the stock
dash gauge but with a real 0-100 lbs/sq/in pressure gauge. Concurrently he's
used a real vacuum gauge to determine that at 70 mph his engine is pulling
between 15-17 inches of mercury measured on an outboard vacuum gauge.
