Default Boost Machine

Hi!
After some testing with the relief valve and the pressure reg I found out that you don't need the one way valve. I installed the relief valve before the N75 and the pressure reg after the N75 and everything works fine. No boost lag at all after shifting.

Default Ralph's car is pretty heavily modded...>>

The purpose of the one way is to spill the pressure in the wastegate and line from the N75 quickly on shifts... Quicker is better.

Hi Steve!
I think the N75 works like the one way valve when you install the 2 valves my way. At least, it's worth a try if you can save the money for the one way valve + the parts to fix it.

It actually only adds $10 to the cost though...

:-) I like it cheap.
I used the Pressure reg from Norgren # R07-200-RNEG(0,3-3,5bar). It works perfectly and I only paid 60$ for both valves and the parts to fix them.
