35 psi? I have never seen a pulse that low. Ever. (Except on a blown engine, which gives 25-30 with missing pieces of apex seal.) Maybe we do it differently. I simply take the check valve out of the bottom of the gauge and crank the engine with the plugs out of both rotors and the gas floored (about 400 rpm).

I tested a 120,000+ miles turbo II and got 90 psi bounces.

My 160,000 mile '91 has 110 psi bounces.

My 199,000 mile 6-port had 105 psi bounces even after the coolant seals failed.

I don't know if the pulse is actually 115 psi, I watch how high the gauge bounces (there may be overshoot).

The factory tester actually graphs instantaneous pressure on a chart. I have seen several traces and they usually run about 8 bar (120 psi).

The FSM recommends that no pulse be below 80 psi as I recall.

Think about this:

Starting air pressure 14.7 psi
compression ratio 8.2:1
final pressure = (14.7 * 8.2) = 120 psia = 105 psig (assuming constant air temperature, which is clearly not true, so the pressure should be higher). Any air lost past seals comes out of this total.

I can list a video of the gauge bounces if this would help.

What to you do for 35 psi readings?
