Boost Leak Testing 202: Hair Spray 1080HD
Why do I know about this?
I'm tired of being the one knowing all the weird crap. If everyone knows
it, it won't be weird anymore. It will be commonplace. By the time I'm
done sealing up all of my own Boost
leaks, all of you will also be experts as well. I'm sure most of you would
teach me something, too... but you subscribed, so here it comes...
something I learned in my travels...
Also, thanks Ilya M. I've only heard about it twice in my life. It worked
great for the one time I've ever needed it, and I'm a huge fan.
Boost Leak Testing 201: Using the tool.
This is the second part of the Boost
leak testing series. In this video, several examples of possible leaks you
might find are exhibited, as well as suggested fixes. Hopefully this video
helps turbo cars around the world to be
healthier and more powerful.

Boost Leak Testing 101: Building the tool.
If your intake isn't sealed up and completely air-tight, then your turbo is working harder to produce fewer
results. This is a tool used to verify the integrity of the intake, and to
find trouble spots that need attention.
When your turbo is busting its fins to
compress air, why not make all that air go where it belongs... with more
fuel... to make more boom.
This version of the tester with clamp-style tire valve stems in the cap is
ideal because after you have the intake charge (from an unregulated
source), the schrader valve allows you to disconnect the air hose you're
charging it (silencing the hiss of it) so you can hear where small pesky
leaks might be hiding. Testers without the clamp valve are a waste of
The parts list is available here:
Boost leaks can cause idle problems,
misfires, backfiires, squeaks, quacks, honks, or even seem like nothing at
all is wrong except your time slip is a second off at the track.
Everywhere one part of anything bolts to another on the intake, it's an
opportunity for Boost leaks. I've
blown Intercoolers apart.
Not the couplers, the end tanks. Ever wondered what PSI the wastegate
actuator's really opening at from standing over it in the engine bay?
Build this tool.
Until you've verified this on your equipment, you have no idea.... Every
car I've ever tested has Boost-leaked out the Yen-Yang.
How to adjust / pre load wastegate actuator
1. Remove C clip on the waste gate arm
2. Undo the nut that holds the rod extender.
3. Rotate the actuator extender clock wise so shorten overall length.
4. The actuator rod should be half hole length short to the wastegate arm
when waste gate is fully shut.
5. Pull the actuator extender towards the Exhaust side and securer the extender.
6. Fit the C clip back to waste gate arm.
7. Tighten the extender nut.
How to check a wastegate to make sure it functions properly
We are out to prove that the ebay turbo's are just as reliable as the big name turbo's. One consistent issue with them is
that the wastegates on them need to be moved and tested before
installation. Note that the wastegate arm should not be TOTALLY loose as
shown in the video. This is shown in the video just to show the difference
between how it was before when it wouldn't open the wastegate and after,
when it's been adjusted. This is how to do it.

went dead at the end of part 2, so we had to do the test drive vid the
