I posted this on CF but I know some of you arn't on there so I figured I'd let you see it too.
I think I have it dialed in pretty good right now. lights almost right away, makes 45psi. Mods are, ground fuel pin. pump almost maxed,(unknown injectors) procomp lift pump, timing to the head and 4" exaust.
With this turbo I hit 1700* at 85mph in 4th gear. before the turbo and the timing I could hit 2100* in 4th gear. A few more mod's are in order but I'm getting closer.
If you didn't know this is a he351vgt. I'm useing drive presure to open the turbo, a spring to close it and boost to balance it out. I have a filter and a needle valve on the drive presure line.

. Back pressure opens it up to make it essentially a larger housing correct? I mean obviously the hosting isn't getting bigger but when the viens move it does the same thing. The spring returns it to the smallest?
