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 time. The parts list is available here: http://www.honda-acura.net/forums/do-it-yourself/148666-diy-for-the-turbo-guys-bosst-leak-testing.html#post4766657 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 Make A Boost Leak Tester
I figured with the last video there needed more to be done. I hope this helps to find those pesky leaks you cant always see.





Wastegate Spring Rate and Spring Pre-Load Explained
This vid demonstrates the how spring rate and spring pre-load work on a wastegate. This is a good primer for understanding how springs operate in application

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. Job done





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.





WRX turbo swap pt1
part 1 of what turned out to be a three parter. the battery in the camera went dead at the end of part 2, so we had to do the test drive vid the following week.

Mechanical vs electrical boost gauge comparison - NewSouth Performance
This video compares the performance of the NewSouth Performance mechanical Boost gauge vs. one of the industry leading electrical Boost gauges. A mechanical Boost gauge is faster and more sensitive than an electrical Boost gauge. When properly designed and installed, a mechanical gauge is just as accurate and does not have any gauge buzzing or needle fluttering.
