where did you guys run the boost line off of, I'm running mine off the line to MV but it just shows vacuum.

 

This might sound silly... but have you driven the car and gotten into boost rpms with the gauge? I show vacuum that diminishes as I accelerate, then it goes into boost around the 3,500/4,000 rpm... somewhere around there.

 

hell no, just drove around the block. (25 mph) didnt really get on it.
I check later.

Thanks

 

ran it up to 5K and the gauge only went to 0. I'll try a different line.

 

You should hook up the gauge line to a port on the intake manifold, usually in the plenum area.You can "T" off of your MAP sensor, or if you have a Magnuson, there is a port on the driver side of the blower manifold.

The gauge showing vacuum thaat diminshes and becomes boost is normal. vacuum is negative manifold pressure, boost is positive manifold pressure.

Hope this helps

 

You know what's silly??? I drove mine for the first time this weekend and when the car went into boost I was hanging on for dear life and couldn't make myself look over at the gauges! Hopefully I'll build up courage in time.

 

I've only got 1,500 miles on the car so far and I'm just finally starting to get comfortable prying my eyes off the road to watch the boost gauge. Finally figured out that it's not what rpm in you're at (provided it's above 2k rpms), but it's how hard you stab the throttle that puts the car into boost. Been toying around with the rolling 2nd gear burnouts... trying to find the sweet spot to get rolling 3rd gear burnouts. No clutching of course... that's cheating.

 

Digital boost gauges are easier to read. A quick glance over will tell you what the boost is instead of trying to focus on the needle and little lines while your also watching the road, tach and trying to shift.

 

Hi Tom,

I saw you posted a while back about going to a 3.2 pulley. Did you get your re-tune? Curious as to what increase you saw with the pulley change.

Thanks,
Doug

 

I've been waiting for some new tuning software to come in to take care of that. I usually only run it up to about 4000/4500 RPMs with the current programming (just to be on the safe side ). I may wait until after the winter to tune it. Just incase other mods find their way on the car while it sits over the winter.

 

Tom,You are one "nice guy"!
