DIY manual boost control

[KevinB]

Anyone have a good recipe to make one?

I found this one, which looks like the RJC one:
DDG- Homemade boost control

basically it's a grainger valve you can buy here for cheap:

Kevin, I have one I'll give you in BG if you want to try it. With a heads up car (TSM) I don't think it will do what you want.

Thanks Jason! I don't have the funds right now to buy anything fancy:frown: I'd love to go with one of those new systems...maybe later this summer. As long as it holds me at the TSM legal 24 psi...it'll work

made 2 of those , the hardest part is drilling the the .020 hole ,one barbed fitting the valve and a 90* fitting at the end that you just hammer in the end hole , cost is like 10 bucks. Same as the RJC ones.
