Are they practical for anyone running a supercharger?

I've never heard of or seen such a thing before.

Heard of 'em, and seen 'em.

No problem for us. We have plenty of vacuum.

probably the only product worse than the powermaster. if i were so shy from engine vacuum assist i'd go w/ hydroboost for sure.

Hmm. I loose vacuum in the HVAC when I've been in boost for more than a couple seconds and it goes to floor and defroster. Not worth 80 bucks to fix.

I recall reading an article in I think HP Pontiac several years ago about how these were used in some Pontiac 6000s in the mid and late 80'*. They recomended them for people who were running big cam muscle cars that had no vacuume at idle. I was planning on using one in my 34 Pont Coupe when I actually get it on the road. You might want to try one from a bone yard first. Around here they run $5 - $10 if you pull it yourself. That is of course if you can wait for a 6000 to pop up. Just a thought!
