Anyone have experience with quickspool valves?

Presently I have a dyno tune scheduled for the 27th so I can get a comparison on the same set up of my efr 6758 to a efr 7163 with TMIC on non Dual AVCS. (06 outback xt).

 

Then recently a prototype turbine housing with integrated quickspool came up on ebay. Without thinking I made an offer and it got accepted. I'm now realising I will have to modify my exhaust because this thing wont just drop in.

 

Here is a link to what it looks like.

Should I do it? Will it be worth it? It wont give me same to same comparisons, but it might give me low end of the 6758. I'd like to stop at 500-525 hp and not go much over that. But the housing itself will cost me a 350 and modifying the exhaust may be another couple hundred and it won't allow me to go back to the 6758 without modifying again if thats what I want.

 

Would love some quick feedback if there is any.

your nasioc link is broken. It sounds like a cool idea but I think those work better on vehicles with shorter manifold primaries.

Qsv’s have been used in the Supra community. Are you on standalone? What kind of manifold are you using?

Stock ecu. The qsv is boost activated.

quick spool valves only work on twin scroll turbos that are bolted to single scroll manifolds.
