i am wondering if it would even work, and if anyone has ever tried it.

Basically i would use a small *** turbo, like an ihi or something very small with an internal wastegate right off the the manifold (can be boost controlled). Then on the downpipe of that turbo a larger t3/t4 70 trim or something sits. On that downpipe is an external wastegate. Basically making a very broad powerband w/o the sucky low end.

here is a shity *** diagram of what i am talking about.

the only problem i can forsee is the T in the charge piping the bigger turbo blowing out the smaller one thru its compressor housing. I think that it can be solved by a kind of valve used in PVC piping (i forget what it is called) that is spring loaded and when pushed the wrong way it seals.

 

look up sequential turbos cause that is what you want to do

 

what is that a moose?
1. Your mspaint cariboos are ugly.

2. Thats probably the most inneficient way to spool 2 turbos.

3. Your missing a bank.
