pressure testing intake system...
 

so i have everything that I need to pressure test the intake system. Started the procedure with the compressor set at 10psi and the hoses looked like they were going to pop so I stopped. Is this normal? Everything was ballooning up in a way I didn't know was possible.

Same thing happens when the turbo spools up.
 

Don't go more than 15psi to avoid damage to the MAP sensor, and be careful of the MAF to turbo hose - they dry rot and will tear if pressurized.

Samcos, FTW.
 

If your system goes to 16 psig, and the hoses don't pop or come off their fittings, then I imagine you can go that high with a compressor.

I have heard to not exceed 15 psi. So, go 15, and note how much the stocks hose bulge, and think carefully about running Samcos.

Samco's are out of the Q until I go FMIC.

Thanks for the tip.

I guess I could still replace the MAF to turbo hose though.

There isn't a direct fit aftermarket hose for that location. OEM is teh best.
 

Call Carson at Riverside Audi for one.

Are you going to do a "brew your own" FMIC?
 

Or one like Apikol?

The MAF->turbo hose, if unripped, doesn't need to be replaced, because it isn't under pressure.

If you're bleeding boost, then you need to replace one or more of the three boost hoses, the x-over tube (it can crack), or the IC (the ones with plastic end tanks can crack).

The usually culprit is the flex hose between the x-over tube and the IC. Oil collects in it and weakens it.

Even if you only bought a Samco one of those, you could turn around and sell it in a minute! :)

It will be a DIY FMIC
 

The one I did for my last car worked out great so I am going to make another for this one.

So, if you have a boost leak now, you'll be doing a project very soon!
 

I see. :)
