Now how did you manage to get 10 PSI and and check for soap bubbles is what I'd like to know!.....I can picture Ken driving with Randy sprawled across the engine looking fer lil bubbles at 50 mph..This whole story about doing it sitting still just seems to easy
You can add 5lbs or 25lbs air pressure to simulate the boost pressures
the blower will produce. you can do this while parked ,setting in your shop,
yard, or driveway.
Vacunm line leaks will show up during a test check for boost leaks.
Brandon, you should try and put a hose clamp or plastic tie on every
vacum lines ends that you can get to. this includes all vacum lines,
on the intake side of your induction system as well as the boost side
of your induction system, & PCV valve lines ends..
Your Vacunm hoses are old. they may look great ,feel great.
But can count on that you have some seapage with old rubber lines.
Get 6 to 8, 3/8 to 1/2 inch hose clamps use the metal clamps
on the boost side of your indution system rubber lines, Plastic
ties work very well on the vacumn lines, before the supercharger
side of your induction system.
Propane will show large leaks, but propane will not show small
seapage leaks well.
Clamps and plastic ties are cheap, you can install them in a few minutes.
do me a favor and try this out asap as you can. and then get back
to use on this post with the outcome of spending $5.00 on clamps
and plastic tie 30 minute installation.
Ken And I have fabed parts of are intake systems. So we need to do
a pressure check on the complete induction system to sometimes check
are work out. And i run can run up the 25 to 30 pounds of boost.same
with Ken setup. So we needed to build a tool to pressurize are custom
induction systems. and we both know if we run high boost the silicon
hose connection will not leak or blow off.
So I do not think you need tool fab a tool like we use. To pressurize
the complete induction system. Just inspect and clamp or plastic tie
every vac and boost line you can get to. Your car will run better
if you do this.
But clamping all the boost and vac line may not fix your problem.
but you will know this will never be a problem again.after clamping
all your lines,and you still have problem . Them check for IC tubes
for leaks and reseal if needed.
Hope this helps ya some Randy
