Well, in my research, I've come across quick spool valves. These are used on divided housing turbos and effectively cut the exhaust housing's A/R in half up to a certain boost level. So, a very large A/R turbo, best suited for high RPM power can still spool and build power at lower RPMs as well. These would seem to be an effective route for a remote mount setup, taking a well breathing turbo (say a GT3582r with a .86 A/R housing) and making it spool in a manner similar to a K03. I'll be most likely using one of these in my build in order to manipulate the turbo behavior and power potential. On an E85 tune, I could effectively build 600 whp (if I don't break internals) while still being able to see boost at 2000-2500 RPMs on a 93 tune and build 450-470 WHP. Exciting stuff, and fairly cheap too thus far (compared to other turbo builds I've done), that I'll be doing.
