I'm building a manual boost controller for my Turbocharger.

Here is a pic of the parts from the hardware store. Building is kind of an overstatement. I am really just screwing 3 pieces together.

And the parts, assembled ready to go into the car.

WOW huge project huh?

LOL

Thats exactly the same thing I did!!

Works pretty well and you cant beat the price ~$5.00. The only thing is that with my car I need a bigger valve, cause in the higher rpm's I am losing boost due to the fact that the valve can't bleed off enough of the air.

I forgot, but I am sure you are pretty well aware of what you are doing, but be very careful. Open the valve 1/4 turn or so at a time, and I noticed that I get a boost spike for a little bit and then it sort of levels off. How much boost is your motor capable of handling? And what have you done to lower the compression (just a headgasket or did you swap the pistons)?

These motors can only handle 10-11 Psi on very high octane fuel. I have not lowered the compression, I only want a pound and a half or so more boost out of it (and only at times...)
