Im a bit slow today but think I get it now. The quick spool valve fits between an undivided manifold and twin scroll housing. At low rpm the valve is closed and all the exhaust gas is diverted into one scroll for quick spool. Is that right?

fixed it up.

Thanks man

Just a tad dyslexic haha

Single scroll manifold with twin scroll quick spool housing would work well

Still a restriction in the exhaust though but im sure the benefits outway the cons

OP, I had a PTE6235 and now a GTX3576r. The GTX does spool about 400-500rpm earlier, but feels slow compared to the Precision. Spool is similar to the GT3576 and keeps pulling all the way where the GT drops off after 3500rpm. But there is no comparison to the PTE6235, once it comes on boost it is sensational and pulls way harder than the GTX. From 2700rpm the midrange is sensational. On pump 98 you are looking at 50-60rwkw peak power difference, but it is much more in the midrange. On the dyno I was hitting 400rwkw by 120km/hr.

To me the GTX3576 is soft and the PTE is the ultimate street turbo.
