Idea to spool turbos faster?
I know it may sound hokey, but I've heard of people using their air pump as a "supercharger." Would an air pump provide enough CFM to help spool a turbo if it was plumbed into the exhaust manifold? Would the differences in temperature cause too much turbulence?

I was watching a special on American Movie Classics or something like that on Drag Racing.They had a 4 cylinder intergra funny car on there running twin turbos.Anyways they said they were spooling the turbos with Nitrous but said it was against the rules right now.Are they talking about something else besides the obvious?

what about creating backpressure, maybe a pressure sensitive plate in the downpipe which opens more and more with more exhaust pressure. That way you have the flow of a large diameter exhaust and the spool of a smaller one.

Don't sportbikes have something like this? Yamaha's I remember being called an EXUP valve. I'd check into this, but it would seem to require a large chamber to accomodate the area lost to a butterfly assembly.

Wastegate Control!
It's all about wastegate control.......I have been reading about these type valves to control the wastegate:
http://www.dawesdevices.com/boost.html
and
http://www.dawesdevices.com/race.html
They keep the wastegate completly closed until the desired boost level........this works very well on my car! The improvement in turbo spool is VERY impressive. Take a look and maybe you can get the same parts to make your own.
Hope that helps.....
