run a T then on one leg put a 1 way check valve and on the other end put a open/close valve. re-tee and run to the boost gauge. When you close the valve, the 1 way valve will keep boost from returning, and will peak hold. Open the valve, and you have your normal boost gauge!
Gauge --<==valve on one side check valve on other=>--boost source
- is vacuum line
< is tee
= is two vacuum lines in parallel

Are there any differences between different 1.6 NA exhaust manifolds?
Ie are all manifolds (OEM, JDM, etc) made of the same metal and do they all have the same bore size?
I plan on grinding/ removing the internal welds to increase flow.
Let me break down the question...
