I am debating this now. I ordered a POS manual boost controller and it will not go below 10-12 PSI.

I want 7-8 PSI up from the 5 PSI I am seeing now.

If I get the 9 PSI spring that should do me.

What I am MOSTLY concered about is boost creep. I am about to go to the 8:1 FMU and if I boost more than 8 PSI I might have a serious problem.

I am looking at an Air Tool controller as my boost controller, the rx7 guys dig them

Just curious what the general opinon is??


And the price is $15 for both

 

get both so you can get a minimum of 9psi with the spring and then use the boost controller to turn it up from there.

 

i have a avcr for sale
electronic boost controller is most safe always accurate to the point. wanna buy it let me know used on my car

 

thanks qn, but I got a grainger valve and stuff for $15

 

If you're worried about boost creep, you need to be thinking more about the flow rate of the turbo and/or the size of the wastegate....and less about the actual controller.

 

Very good Engloid, but with running/staying under 10 psi, that is not much of an issue. With the current market of wastegates and their high-performance orientation, this is not a problem, especially with Bags running a Deltagate wastegate. He just needs a GOOD controller to control what boost he does have lol. And also, with that low of a psi setting, if boost creep were to occur, it may spike at MOST 1-2 psi above the current setting, which is WELL in the safe zone for our engines.......
