how to leak test blow thru setup

[whitedevilstealth]

How would I go about leak testing on my blow thru setup

[Sin'sVr4]

i would like to know this also

[whitedevilstealth]

I guess we could always put the stock bubble and pipes on and do that but what a PITA

[Sin'sVr4]

i dont have my bubble anymore, but sure I could get one. I think im gonna fabricate a pressure tester for blow thru set ups.

block off one turbo with a rubber pipe cap. Then build a circular pressure tester for the other side like this:

Tried to find it on this site, but only found it on the other site.

go to the hardware store and buy a valve stem and a pvc cap

drill a hole in the cap and push the valve stem through it. then just remove the ic pipe going to the maf and put in the pvc cap. pressurize and bam your done.

Block off the least accessible turbo, then fit a cap with a valve stem onto the other.

Be VERY careful that those caps don't blow off the turbo and fly around - I did a similar tester for my evo and somewhere around 25psi the cap popped off. Scared the peanuts out of me. The black couplers should be right near the PVC caps.

I have a Rob Beck pressure tester that fits in the stock air bubble. I ended up getting a 3.5" to 3" reducer and a 3" cap so I can pressure test my blow-through setup. I couldn't even build any pressure because it was leaking out my MAF sensor so I'm going to see how well I can get it to seal up. You can build a pressure tester pretty easily just block one of the turbos off.
