Guides - DSM - Instructions for Boost Leak Test

Special thanks to Patrick Killian probe_svtr@hotmail.com

How to: Boost leak test using the Boost Pro: Boost leak tester: (note: this test was done on a 1g with a T04B running Maft translator in blow through mode.)
Warning: Only pressurize your intake to the amount of boost you run/ plan to run. If you over pressurize your intake tract damage may occur.

Before you get started Boostpro would like you to know that we are not responsible for any damage caused to your engine. As long as you follow basic instruction and DO NOT exceed 7 psi of pressure while pressurizing your manifold there won't be any problems.

Now let's get started! (click images to enlarge)

Tools required

Screwdriver: Phillips or Flat head depending upon your hose clamps
Pliers: Bov return line clamp
Socket wrench
Socket set
Air compressor/Gas station

Others pieces needed:
Oty. 1: Coupler to connect the boost leak tester to the turbo inlet. The Boost Pro unit is 3in in diameter so depending on your turbo size you will need a 3 x ( X ) coupler. If you're running a TO4B or TO4E you just need a 3 x 3 coupler. You will need to measure your turbo inlet to figure out what size coupler you will need.
Qty. 2 : Hose clamps/ T-bolt clamps. You will need 2 hose/ t-bolt clamps. One clamp needs to be at least 3in in diameter and the other depends on your turbo inlet size.

1- Remove Intake/Air Box.

A. You will need to remove your stock air box and MAF, The air box is bolted in with 3 10mm bolts. Unplug your MAF and loosen the hose clamp on the intake pipe holding the MAF in place. Now the air box and MAF can be removed.
B. Remove the BOV return hose and PCV valve hose.
C. Loosen the hose clamp that holds the intake pipe to the turbo and remove the intake pipe.

2- Install coupler & hose clamps on the boost leak tester.

A. It may take a small amount of elbow grease to get the coupler to fit over the tester
B. Once you have the coupler where you want it put a hose clamp on where the coupler and boost leak tester overlap to hold the tester in place when you pressurize the intake. Make sure that both clamps are tight.

3- Pressurize the Intake Track:

A. Get out your air compressor (make sure you have the fitting that you use for inflating tires on) and simply place the hose from the air compressor onto the schrader valve of the boost leak test.
B. Watch the gauge on the boost leak tester so you don't over pressurize.
C. Once you reach your desired pressure remove the air hose and listen for leaks.

4- Fix leaks and re test

5- Uninstall tester and reinstall your intake pipe, MAF (remember to plug it in) & Air Box, BOV return line and PCV line.
