About the Boost Controller:

It's a ball and spring style valve. Comes with a brass ball and a spring that can hold 20psi.

May I ask what you need the datalogs for?

Probably so he knows it's going to someone with a running car that will be able to use it and not just hoarding parts.

Do you take video as payment?

Gotcha, does it just have a **** on it that twists?

I'm looking for something that is a little more accurate, with clicks or something. Mine is kind of all over the place and I have to turn, guess, turn, guess, etc.

That's the one i have... Simple screw.

^ Agreed. My ball/spring is all over the place too. Sometimes half a turn is 1 psi and in other places, a 1/4 is a few psi.

Now that makes no sense. What kind of a spring are you running in there? Also is the screw good?

slmhofy

iTrader: (5)

Honestly it looks like the spring had been shortened or something. 8-10psi is like 1 turn and 10-13 is like a half.

Actually I can provide a MS log for one of these or get in line at least. OP, your PM box is full.

Your spring is too stiff, thats why. The more you tighten it, the more it takes to compress it.

F=-kx

You want less k more x yet the F to remain the same.

Sorry fking account got downgraded since I didn't resubscribe.

I'm thinking about building like 100 of these and selling them for a tiny profit. I had one on my Miata back when it was turbo and it was so amazing I loved it.

Anyways I want some data so I can show people they actually work really well for the price, as long as you just need something basic.

These are the grainger valve style ones you can build off mcmaster carr for like $15. Just a screw type ****, I'll get pictures tomorrow maybe.

Is this going to be a bleeder type? I've heard these are better than just a plain ball and spring.

This ---- is legit.

It's easy as fk to build, so not really something I would try and sell on MT.net. Since it's so easy most people on here would just do it themselves.

Inbox is cleaned out now.

iTrader: (19)

Kinda think the T valve is better design.

The T valve is a ball and spring valve also. I dont see any one posting difference in performance from grainger vs T valve.
