I am almost finished making an airbox for my ITB's, but i need a bit of advice.
I've cut the four holes in the backing plate (carbon fiber scraps from someone else's project) and i've put in the rubber fittings and trumpets in, but lo & behold, i made the openings maybe 2/16" too big. The trumpets fit well enough, but with the little extra wiggle room i now see, i am afraid of vacuum leaks. Question: Is high temp Silicone the answer to my dilemma?
Also can i use the same high temp silicone around the edges of the airbox as a grassroots replacement for a gasket?
pic of early design posted here before: mock-up
What about running some 1/16" wall vacuum hose, split lengthwise to use as a sealing grommet kind of thing around the inside of each hole?
Sweet air box.
not a bad idea, and it would be removable, no messy RTV to deal with... thanks i might see if that can work.
sorry to dig up old thread, but thought you guys would like to see the test fitting i did today:
had to make the plenum because my car has a MAF and so open trumpets is a nono without standalone EM$
The plenum is high temp plastic, and yes its transparent.
The car is my 2003 Toyota Matrix (1ZZFE 5spd manual).
bought the plenum cover from this guy:
John Hartley
yeah, that's pretty slick!

Coolest Matrix engine bay out there???
I would love me some ITBs, sumptin' fierce but Cali says, "NO, BAD DOG, NO ITBs FOR YOU!"
I'll post a video when they go in next week. I'm hoping its going to be a smooth install now that we've figured most of it out. I'm just praying it nets me more power and i haven't committed the sin of embarrassing myself on tha internets
