Lettuce Build Thread, Fast Cars and Fast Women: Stage 2 and Beyond

[blbroo]

Been noticing lately that my car hasn't had the get-up-and-go it once had. I've just been attributing it to the 80-90 dagree days we've been having but today it was feeling extra sluggish. Then I start noticing this whooshing noise whenever I started hitting boost. Now I'm thinking I must have a boost leak. So I pull my car in the garage and go hunting. Then I come across the cap where my sound box used to be:



It was barely hanging on when I got to it, I was able to pull the tip right off with almost no effort. I'm guessing that under vacuum it was sucked shut so it didn't affect driveability at all, but when hitting boost it'd pop open and start letting all my precious boost escape into the atmosphere, undoing all the hard work my turbo was doing. So I replaced it with another one and the lettuce mobile feels like a whole new car again.

@blbroo I heard on the grapevine that you had this exact same problem. I'm thinking it's at least partly due to the meth eating away at the rubber from the post-IC nozzle we're running. Were you able to come up with a better solution? I figure this'll buy me another couple months at least, but would like a more permanent solution before it starts happening again.

Mine did the same thing. I tried a harder plastic cap, but it didn't seal 100%. I'm going to pick up a rubber drain / boat plug and double up the blockage power, tomorrow


Crazy idea, but, could fill the soundbox and hose with something, then reinstall it

Nice, keep me updated. I'm going to take a trip to the hardware store sometime soon and see what I can McGuyver up. I'll keep you updated as well if I come across a good solution.

Try cutting the neck off and use repair wrap: http://www.homedepot.com/p/1-in-x-1-...4006/204400319

Holds up to 60 PSI so it should work.

This is a pretty cool idea, Andrew. Might be a tough area to get a smooth wrap around, but worth a look.
