Its Time To Build Some BOOST!

Bill what's the latest update

I'll probably do some leakage tests on my co2 operated boost controller in the morning I made a small ball valve fitted with a 4an straight on one end and a quick disconnect air barb on the other that ill plumb into the feed of the controllers solenoid and test it with controlled air and hopefully I should beable to fix any and all leaks then i can slowly start turning up the boost and see what the valiant has

Tomorrow (Monday) we will take the car out on the freeway, where we can really get into a full-throttle situation and see if what we did accomplished anything. We went 2 steps richer on the primary jets and 3 steps richer on the secondaries. It did show a richer mixture in some preliminary local driving, but we didn't have a chance to crowd it into a full throttle situation, yet. We will, tomorrow.

I also tightened up all of the manifold-to-head stud fasteners (some were not very tight) and will check the BOV setting before we run it again.

This 66mm turbo is brand new, so I don't think it's the problem, as it's identical to the one used on a Buick GN I have ridden in that makes 25 pounds of boost, readily. That Buick V6 is an engine that is virtually identical in size to ours, so I don't think it's a size-mis-match.

I'll let you know what happens, tomorrow.

Good luck with your power valve exercise. We may do a similar setup if yours works well. Ours is already boost referenced, so all we'd have to do is add the CO-2 mechanism. right?

How do you regulate the CO-2 pressure to get the desired amount at the power valve?
