Quick spool valve for Turbo set-up any feedback ?

[onestepx]

Hey guys just ordered this for my set-up supposedly gives you quicker spool-up & increases torque .Anyone else on here try this product yet looking for feedback.
Also going with Bosch 2000CC injectors would like some feedback as well for anyone on this set-up.

Are you referring to the quick spool valve from SP racing? It was used by Lovefab for a one off system with a Comptech 3.5 ow compression stroker motor

A post I made on another forum.

We recently finished a full build on a customer's 1997 Toyota Supra. One of the many parts in the mix was an SP Quick Spool Valve. From the packaging, instructions to the quality I was throughly impressed. We installed the SP Quick Spool Valve between the Precision 7675 "GT42 Style" with a 1.28 a/r turbine housing and our Induction Performance exhaust manifold.

* The overlay below was done on pump gasoline 93 octane at 18lbs being lite on the tune. The blue lines are with the Quick Spool Valve. The red lines are without the Quick Spool Valve.

What this dyno sheet does NOT show is partial throttle and transient response. I've driven a lot of 7675 3.0 2JZ's. None respond as well as this one does. Much the less with a 1.28 a/r turbine housing. If I had to make a partial throttle comparison I would compare it to a 6768. I like and approve this product. I will begin offering it to all our customers here at the shop.

BELOW IS THIRD GEAR. BOOST WILL MOVE LOWER INTO THE RPM IN FOURTH GEAR. I WILL TRY TO GET A LOG AT TX2K12.

I've been following this for a year or so. I don't have a turbo setup so haven't tried. Seems like a clever idea though. They also sell/use a boost dependent exhaust cutout valve in their systems. It's a concept i've used before and now building an exhaust system for the NSX to do the same.

Subscribed for updates....

Real good. Always busy. Good to hear. The 6766 has been my favorite turbo for some time now. That's a real nice setup! That setup will def be in the 9's.

Did you get to install the Quick spool valve on your NSX, and how is it running?
