What is your max boost and drive pressure?

HTT 64/71/13s So far, I've managed a spike to 55 and 70psi with the gate closed at 50psi

150hp sticks and a stage 3 pump. That sound right? I'm wonder if I should spool more (never mind if the drive pressure is way to high).
 
95-98 psi boost this last set of pulls....`135-140 of drive 64/71/13 as the secondary.

Had the gate pretty tight considering my primary turbine is fragged pretty good, and figured I'd be doing most of the work with the secondary.

So the new gate can hold it back thats for sure.....just about puked when I seen the drive was that high on the data logs, that much overhead would have been killing HP.
 
66/71/16ss boost 62psi and drive 119, a little spray.
These 66s will stay together @ 62 lbs boost? I have mine cranked up to about 55 lbs but a little uneasy about going higher. The waste gate actuator is quite tight and the gate may not be opening. "It will spike a bit above 55 at lower rpms"

according to Brady.... anything over 55psi on a 66 is just blowin' hot air.
 
59 psi with 64 psi with my 468 with old 5x16s and 20 degrees. Haven't checked since new injectors went in. No gate with the above numbers.
 
With a Super B Special and 90's I have the gate set at 53psi boost and 55 psi drive. With the gate fully closed I see 60+boost and 75psi drive.

The life was about 1300 miles, but it ran well.
