Way of testing for exhaust/boost leaks?
I found this on somebody's website. What do you all think?
-------------------
Ever been on the track (or street) and realize that you're not getting full boost out of your GT-3 951? Here is a trick I use to find those pesky boost leaks. I have a Huntley MAF so it's easier to do then the stock system but still possible with stock.
Pull off the MAF forward of all the hoses that connect there. (If you have a stock intake system you would remove the intake to the throttle body)
Make an aluminum plate with a cork gasket seal and bolted it in the MAF's place. In the center of that plate drill a hole and tap a fitting for an air line.
Make another plate with cork gasket and bolt it in place of the Cat Back system. This is done by disconnecting the exhaust pipe behind the catalytic converter and installing the plate.
Apply air pressure (don't put 120 psi on it) and listen for the leaks in the intake and exhaust. This method even pressurizes the crankcase so you can find that pesky oil leak too. It's fairly simple to make, and I found boost leaks I never even thought of.
Have fun, and turn that boost up.........Bill Shook
