Has anyone else heard a pop, like a baloon when under boost? I had it happen last night and it felt like I lost boost at the same time. After letting off I hit the throttle again and was able to still build boost (only reved enough for 3lbs). I checked all of the couplers and could not find any out of place. I have blown the couplers off before but never had one, theoretically, swell up and pop off the pressure.

I will be doing a boost leak later tonight but thought I would see if anyone else has experienced this.

backfire?

I was rollin with the top and windows down and am pretty sure that it came from up front.

I've heard such stories but haven't experienced 'em. Hell, anyone runnin' a turbo better DAMN sure run a thorough leak test before SUNDAY!

Found a serious leak right at the compressor outlet. What is the general concensus: Gasket or black RTV between the turbo and J pipe? I guess I have never tried both

I tried just the gasket when i had my GSX and it leaked like crazy. Before i tore it apart someone just used RTV silicone. I ended up using the gasket and silicone and it worked just fine.

I gave it a light sand papering to get all of the old RTV off and then gave it a fresh layer. My guess is that the way it was leaking I must have actually blown the seal that the RTV had going. Also, as I was tightening one of the bolts I got that stripped feeling(the bolt not me). I think the last time I quit when it felt as if it was stripping, but having just seen that the threads were OK I kept at it. In a few more turns it snugged up real nice so I think it will hold better this time.

Thanks for the replys!

A couple of days ago I was leak testing again. I noticed that I still had a decent leak around the compressor housing/ J pipe connection. I gave the system a little extra pressure this time and... what the... the damn J pipe is leaking around the flange! Whoever does RREs J pipes did a crap welding job and left a couple of pin holes. I hit them with JB weld inside and out.

The moral of this story is that the debate of gasket vs. RTV does not matter if your flange leaks...

Why does it have to be about race dan??

Black RTV works in somany aplications, the posibilitys are endless.
