hey guys. i made a previous post in the engine section and i have a different question now. i cleaned the goop that helps seal the throttle plate and now my idle is all screwed up. i tried a fix of a thin layer of rtv, but it didn't help too much. my next step is a new throttle body.

so has anyone have any real world daily driving experience with the boomba? i don't want to get mine ported so milspec is out of the question. the boomba seems like a nice piece, but searching came up with one guy saying his rusted out after 1200 miles, and a bunch of dyno graphs. i just want some feedback of people daily driving the throttle body. any issues with idle and such. i have a drop-in, turboback (with stock cat for emissions), licp and that's it for the mods. the rest is bone stock. feedback with that setup would be nice but i'll listen to any stories anyone has. thanks guys.

I actually made a post in the engine section too about the same issue... not much help there. anyways, I searched around the web for about a week or so and did not come across much useful information. I did come across some helpful info, though. I even came across an old thread on here that mentions a solution to this problem too.

Apparently, Dow Corning makes a spray called Molykote 321. You tape up your throttle plate and throttle body, and spray where the factory goop was and let it dry. I sprayed on at least 5 or six coats of the stuff. After you're done spraying, it's a good idea to take a bright flashlight and shine it through the inlet side of the throttlebody and look from the other side of the throttle plate to make sure there's a tight seal and no light gets through. After it fully cures in four hours, remove the tape and open up the throttle plate slowly. The Molykote is supposed to crack open but stay on. I originally thought that it would crack off nice and even with the edges of the throttle plate and throttlebody bore, but it actually doesn't. Even though it doesn't crack off evenly, it seals off the throttle plate nicely after the throttle is closed. I'd recommend you use your Tactrix cable and Evoscan to make sure your base idle is where it should be with the SAS mode after you're all done.

Anyways, it's held up fine for me for the last week or so (fingers crossed). Apparently, only industrial supply stores carry this product. I was lucky enough to find it at my local Grainger store. It's a little on the expensive side, though ($30ish). But not as much as forking over a few hundred dollars for a new TB.

They mention it in posts #21 and #29:

This is what the can that I got looks like, but apparently they have two different looking cans of the same product: http://images.google.com/imgres?imgu...26tbs%3Disch:1

Hope this helps and that you can understand what I'm trying to say.
