I’m sorry to bother you guys again.
I feel like I’ve been installing this SC for years now.
So running well, boost plateau at 2.5 pounds.
Should be ample boost after that with current blower and pulley set up.
I see a nice initial swing about 121 kPa by 3500 rpm but then falls off to 115 kPa by 4000 rpm.
Very reproducible.
After several tensioner revisions I feel that belt slip is not the issue.
There is no soft parts that could collapse pre blower.
Smoke test on intake good.
I’m going to drive without BOV tonight to try and eliminate that dysfunction from the list.
Question: boost leak test: how?
Can you turn crank to close all valves and pressure entire system? and if so what position? Throttle plate open I assume.
I remember 20 atdc?
