I have wanted to see a shuttle launch since I was a toddler and today it finally happened. Its amazing how fast they go when they launch! We talked about driving to the space center but after hearing that they were expecting 500,000 people we decided not to go. Luckily some friends with a boat took us out on the water so we could get a really good view.

Here's a really crappy photo:

Quick update, I have a new tune date scheduled with Phil for June 24th. I haven't done anything with the car yet but I found out that except for the 24th Phil is booked up between now and mid August. I really didn't have that day available since I am booked on work trips and stuff all summer so I had to convince my wife to cancel our summer vacation to Colorado. I really hope things work out this time around because I think my wife will kill me otherwise.

That day will be here before I know it so I guess I better get moving!

Speaking of boost control, I am fairly frustrated with electronic controllers. I spent several hours this weekend converting my boost control system to a strictly manual setup with in-cabin controls:

As you guys know, I am switching my boost control system around a bit to help cure the issues I have been having. To begin with, I am going to run dual external wastegates instead of the internal setup. For totally unrelated reasons I am also going to switch to a manual boost controller setup (hallman). Because I run meth I need to have some kind of electronic component to force the system back to spring pressure in the event of a meth failure (very important).

To accomplish this I purchased a special low powered 3-port MAC valve (different form a normal valve used for boost control) that is only capable of being used to switch flow direction. The valve is designed to be run form a direct 12v power source (not pulsed via the ECU) and can sustain being energized long term. The plan is to use the 3-port valve to divert air away from the manual boost controller and directly to the wastegate if needed.

As with all safety control circuits that I design, the valve will need power for the car to run more than spring pressure. The idea is that any kind of electrical failure will only result in spring pressure verses a blown motor (no meth + 30psi + 10:1 compression + 93oct = boom!).

Here's a basic diagram of how I plan on connecting the hoses. I posted this here for a "peer review" so I am very opened to design changes. I would also like to know if there's a way to use both ports on the EWGs, any body know?




Again, here are the key points:

-The valve must be energized for the manual controller to influence boost.
-The valve is an on/off only kind of valve and cant be used for normal boost control.
