Bryan, that guy seems to have a bit more tuning to do.. But his boost never stops rising. It just keeps biulding.

Mike.. The only reason to open the valve is when the half scroll becomes a restriction. The Bolt on BEP housing restricts the airflow of a hx35 to around 52lbs/m. The T3 housing allows the 7blade hx35 to hit 60lbs/m.

From what I can see, the closed valve limits the air flow to 51lbs but open, I can reach 56lbs. I would like it to open just before 50lbs/m. But link dosent use airflow to control the EGR solinoid... So I take a rough estimate of say 7000rpms.

While driving around all day.. The valve never opens. I never really have the chance to go above 7000rpms on city streets with 30psi and a Holset. But at the strip.. It will only stay closed to biuld boost in first. With nlts.. IT should stay open the whole time.

I dont really know what it will do at the strip... But just doing a full lauch and run on a back road.. Its way faster then the BW. Much better pull.
