Author Topic: Boost controller questions (Read 2255 times)

Just about there with my build and I have a few questions:
1) What boost controller are you guys using on a K14 - AAZ?
2) do you just cut the metal line going to the wastegate?
3) with a boost controller, do you still have to adjust the wastegate on a K14 to get 18 psi?
4) what timing are you running with a Giles pump? - I set to 1mm, but should it be less?

Just want to make sure I do this right, thanks for any input.

I bought a boost controller off Ebay and can't remember right now what it was called but it was pretty affordable. I simply cut the metal line and installed the boost controller inline.

After running it for a few trips I screwed the wastegate screw all the way in to effectively lock out it's actuation and now top out at 18 psi all day long - no boost controller needed. I think removing the metal line and plugging the holes will give you the same results.

a simple bleed-type controller can be made with parts from home depo/lowes.

google it.

basically all you need isa relief valve set to your max boost pressure.. you would also need a bleeder hole so the wastegate can return to the closed position.

google "grainger valve"
