Banks Technicooler.....Got it today.....

[Bob4x4]

I just installed mine this morning and now have a nasty sounding leak - like a balloon releasing air or a real tight fart :-laf . It starts around 15 psi, but I am going to go out with soapy water to try to find the leak. If it's those studs with the chinzty washers, how do you stop the leak?

There is a flaw in the seat area on one of the outboard stud mounting areas, hard to see with Jakes ceramachrome coating. We added o-rings to fill the area between the studs and housing and a rubber washer under the standard banks washer. Now sealed up tight at 40 psi.

Bob-



Did you get regular 0-rings and rubber washers from the hardware store? What thicknesses did you go with?



Thanks-

I saw somewhere that you can use shaving cream to find the leak. It might be easier than running your truck flat out for 15 minutes while you look for the leak.

I had an o-ring assortment on the shelf and Jake had picked up some universal washers at a hardware store. He cut one down to fit with a razor blade.

Matt I have a pressure rig that I use. It is the only practicle way to do it. I find leaks at 5 psi or at 50psi.

Bob - thanks for the info. I tried the shaving cream trick as a double check and confirmed that it was leaking at the compressor outlet. It sprayed shaving cream all over the firewall. Shaving cream in the intake horn stud recesses (as well as at other IC hose connections) didn't blow out so I am good to go there, but I'll be on the lookout for some rubber washers just-in-case. Now my engine compartment smells like diesel with the faint aroma of Old Spice!

:-laf I was gonna ask how it worked as a degreaser.

It's still holding foam after a few hours so hard to tell yet!

Mine seems to be sealing OK, but I may double check for leaks anyhow.

I measured my old intercooler and the Banks today for comparison in size, and this is what I came up with.



Stock Intercooler (core): 24. 5" Tall, 28" Wide, 2" Thick, Area = 1372"

Banks Intercooler (core): 26" Tall, 28" Wide, 2. 75" Thick, Area = 2002"



If I did my math right? (been a long time) the banks intercooler is 45. 9% larger than the stock unit.

Make it up at the IC inlet tube, their is plenty of room, You can easily get it to a 1/8 of the turbo flange.



Check the distance from the Banks tube to the IC inlet, Should have 3/4 to 1 inch Room.

Got the boost leak fixed by doing as you suggested - thanks for the advice! Now I'm just waiting for the correct sized clamps to ship from Banks on the intake horn (using worm gear hose type clamps for now). Aside from this, before the Technicooler, my wastegate would open normally at 40 psi yet my boost at the intake manifold was only 30 psi or so when I really got on it. Now, the boost versus wastegate opening is a lot closer together showing a lot less restriction through the Technicooler. It also appears to run perhaps ~50*-75* cooler than stock when I get on the throttle too.

What are these going for? I've been quoted $1170 shipped. Sound about right?
