Anybody else running one of these? There was a lot of buzz around them when they released, but they were only available in 500 and 650 cfm. I found the 800 cfm manual choke version in stock without ever hearing about it's release last week, so I decided to give it a try. I need to put more miles on it to really know but I bolted it on, set idle speed and mixture, and took off. It does seem to me like it is slightly smoother at highway speeds than the holley was, whether that is due to the annular boosters or my imagination I'm not sure. So far it seems snappy, and I haven't had any bogs or stumbles really to contend with. I've made a couple wot pulls to around 4500 with it and it seems to pull nicely throughout the rpm range. Just thought I would offer my first impressions of it as in my eyes the annular discharge booster's advantage is right in the sweet spot of 455 cruising, and the 800 cfm should make a nice q jet replacement in a stock or mild street application.
I used an avs 650 on my truck . Worked fine . Not the AVS 2 version . I talked to Edelbrock about them because down the road a few years when they start showing up used for sale my worry was cleaning out the annular booster fully with the small holes . They said no problem . We'll see . I think the annular style of booster should work well . It would be nice to be able to buy the annular booster to upgrade a regular performer series carb . If possible . That's not going to happen for awhile I'd guess . I don't have any problem running the Edelbrock carbs . Seem fine , no surprises , a few simple tune steps . And the best resale by the way . At least by my experience . Let us know how it goes . I've got a 800 AVS I'm saving to try later and compare to a 800 Holley and a 800 QJet .
I have also thought about over-the-counter replacement boosters, but I'm not holding on to much hope for that. I suspect they wouldn't want people to buy a cheap part for their existing carbs when they could sell them an entire unit.
