fixing v-band boost leaks

[ZeroGravity58]

I thought id post this for anyone having the same problem. I have trents turbo kit and i have NOTHING bad to say. The kit is excellent quality and i would recommend it to anyone. The problems im having is the v-band clamp that goes on the outlet of the turbo. i could not stop it from leaking. Heres what i did i bought a garlock 2" gasket. These are from 2" 8 bolt high pressure flanges good for 1200+ pounds. The gasket fits almost perfect between the 3" turbo outlet and hot side pipe. You have to cut the center bigger and you have to trim alittle off the outside. I did it with a dremel tool. It fixed my problem and where my 4202 was making around 38 PSI of boost im now making around 44PSI after fixing it with my single CP3. I can try and get some pictures of the gaskets tomorrow if anyone need to see.

that scares me! ive got quite a few v-bands on mine i hope they dont leak what causes them not to seal?

what causes them not to seal?

If they are welded with too much heat they warp and not seal correctly.

If the elbow on the y bridge does not seal good does it produce a high pitch noise?

Yes it can. I could hear mine around 10 PSI as a whistling noise. Under WOT it was more a high squeeling noise. I dont know about the flanges warping from welding because mine look fine. Even if you do get the clamp super tight i dont think you can ever stop it from leaking 100% without some sort of gasket. My old downpipe clamp used to leak all the time and i even tried a few diffrent clamps. Im a pipe fitter at work so that where i got the gaskets.
