compressed air - where to get

[canadiandsm11]

Wanting to do a boost leak this weekend, and I don't have access to my buddies compressor. I know some ppl at local shops, but wouldnt want to bother them as they're all fairly busy anyways.

Whats the easiest way w/o a portable compressor? Tire inflation machines (the 12v ones)? I'm not sure how much pressure they pump, and how fast I'd be at the ~25psi that I want. Same thing with the ones at gas stations, or again wont it work?

I'm really not sure what to tell you...

but I can only image driving by a gas station and seeing someone using the tire air pump to do a boost leak test!!

Go to WalMart (or Canadian Tire, given your location) and get a small air tank. They cost less than $20 (which is probably around $15 to you, thanks to my President). Fill it to 100 psi and take it home. I prefer to work from an air tank, even though I have a compressor. I like the quietness, since it makes it easier to do the actual test.

However, make sure the tank has a built in regulator, you wouldn't want to pressurize your intake tract to 50+ psi.

Most tires have to be inflated to 30 psi+. I have a 12V portable compressor that taps into the cigarette lighter for power and it inflated my tires to 30 psi with no problem. It should be able to do the same for a boost leak test. Mine came installed with a gauge to read the psi.

Too slow and too noisy.

Mine pumped it up within 2 mins and if I vaguely recall, it's better to spray the areas with soapy water to see for leaks.

It took 2 minutes?? Geez.....

Yes, soapy water is a good way to find leaks.

Pumped what up in 2 mins? Your tire or your intake tract? Most people have leaks in their intake tract and these kind of pumps won't be able to keep up with the leaks resulting in 0 psi on the boost gauge. I'm able to use bike pumps to pressurize my intake tract but that is because I have little to no leaks, 90% of DSMer's would not be able to do the same.

Get a good bike pump. A real one.

Borrow mom's spare tire.
