I know they are a little expensive, But I was looking at a Aerocharger because they are made so if you want to go to the track and don't want any lag or if you are driving out to the track and don't want to be in boost all the time. All has to be done is to change a screw setting. Has anyone had experience with these turbochargers.

Because for some reason people were under the impression it made full boost by 500RPM, which is never the case for another run of the mill centrifugal supercharger?
There's a reason the VF engineering kit failed.
Acutally, from teh dynos I've seen of the aerodyne turbos, they impress me little as well. Just size the turbo correctly and you compromise little.
here's one running low boost:
I think this was 5-6psi on a 1.6L
Compared to my $150 on wastegate attached to a very similar manifold:
red dashed lines.

This is a friend of mine with a Nissan KA24DET and he's racing in NASA, which he has to stay under a certain power to weight ratio. So his boost on his GT2871R goes low rpm 12.5 psi to high rpm 6 psi, so his hp is as much as a flat line as possible. (thats one good thing about turbos)

Using an AVCR boost controller on a turbo you could have your class HP available over the entire working RPM (redline to after shift rpm) of the motor. That's not going to happen with a SC. Average HP in the operating range is more important than peak HP.
