Fast Intake expanding I have a 92mm fast intake and when I rev the motor the intake expands, my best guess is that at idle when there's the most vacuum the intake contracts, and when vacuum is released when motor is reved it returns to its normal shape, but has anyone else notice their fast intake expanding or contracting, it only does it in the back of the intake back where the map sensor is,
Also would anyone know where I could get some injector seals?, not the o rings to the fuel line but the seal where injectors sit into intake, everywhere I go they say it comes with a new intake or a cylinder head gasket kit.

Are you serious? That sounds really weird. Are you sure it is expanding and contracting or maybe it looks that way for some reason. I don't think what your saying is possible

I wouldn't believe its possible either, but i was checking for an oil leak, and as I would rev it I kept seeing something move in the back of the intake, and realized it was the intake itself. I'll take a vid of it when I get a chance,

Unless its cracked somewhere, I can't see it expanding. The other possibilty is that the bolts that connect the upper shell to the lower shell are loose, and you are seeing the top shell move a little..
But even then it thats hard to believe because the the fuel rails/injectors are in place and those are a very tight fit which wouldn't allow any movement between the shells..
Without seeing it, I would have to assume its some type of optical illusion.

I bought O-rings for injectors at a local Napa store. I just told them what I needed and that it fit a stock 28lb LS1 injector and they came up with two or three of them per box. Good luck.
