That is some really good info there Ted. I really appreciate your input.

T04E-57 trim. Old school 350rwhp. With a good manifold/wastegate and some sewer pipe exhaust you should have full boost by the 3500 range easily.

If you want spool, go with the smallest turbo that will make the power you want without being too inefficient.

Going bigger than you need only moves your powerband further up the rpm range. Nothing more.

Not necessarily...

Another tip...
Your wastegate (actuator) vacuum source location can also influence boost.
Closer to the turbo (compressor) = faster reaction of wastegate = slower boost
Farther away from turbo (compresser) / closer to engine = slower reaction of wastegate = faster boost
Boost builds from the turbo (compressor) then into hot-side IC pipes then intercooler then cold-side IC pipes then throttle body / intake manifold...
The later you open the wastegate, the faster boost will build in the turbo.

Thoughts on incorporating a Sound Performance Quick Spool valve?
