Paxton with boost gage, what\'s your max boost?

Title says it all. If you don't have a boost gage, you can pick one up most anywhere. You can check by tapping into the vacuum line with a "T" fitting and about 3 feet of vacuum hose. The easiest place is where the vacuum line from the engine feeds into the split second unit under the dash, drivers side, right. Your passenger can them watch the gauge while you drive.

Paxton states that max boost is supposed to be 7.5 psi. Mine made 9 psi at 6000 rpm. Probably why I've had problems as discussed in another post.

This would be interesting to know.

Mine normally hits 7.5 psi. The normal max I hit is 8.0 (usually when encountering a quick rev due to wheel spin). Only when I hit the rev limiter do I get up to 8.5 psi. My boost gauge records the max (or everything if I have it connected to a recorder) so I feel comfortable with these numbers as I look at the reading after almost every boost opportunity . Before I changed the exhaust I got slightly more, maybe an additional .2 psi. Note the better breathing (exhaust, heads, etc) should reduce the max boost while increasing flow.

Note no belt slippage and the boost has been quite consistent over the past year.

12psi a mile high, when it is cooler a little higher. At sea level maybe 13 to 13.5 psi. I would like to see 16 to 17 with a bigger crank pulley.
