plastic intake + boost? any good? ive got the stock 5.3 intake off a 1500 an im also planing to run about 6-8psi of boost. some guys have told me that its a terrible idea and im looking to blow the intake off the engine and anoter said i should be fine. with my thoughts i figured id be fine seeing im not pushing a **** load of boost also the intake cant be that week or at least i think it cant. what am i really dealing with and can this intake support small boost psi??????

You will be just fine, my ls6 intake hasn't blown of in 5 years @ 10#'s .
Here's one for ya... https://ls1tech.com/forums/forced-in...u-running.html
Also if your really worried f.a.s.t makes some rupture discs that you can put on your intake. They are supposed to blow releasing pressure in the event of a backfire etc...

I wouldn't hot tank the manifold. I just cleaned a truck manifold last week rebuilding my 5.3L it wasn't to bad. Remove everything from the manifold, throttle body, evap sensor, map sensor, fuel rails/injectors. I scrubbed mine in my safety kleen washer with a old tooth brush duct taped to a 12'' stick. You could do this in a slop sink with degreaser and water too. Then blow it out with compressed air and give it a final wipe down with some brake cleaner on a rag.

yea i just washed it in a solvent tank ran a large plastic needled brush down the runners and tunnle of the intake then sprayed it out with brake clean but i still have **** stuck and built up in it. the owner of the truck it came out of ran this engine like **** i just re finnished the heads they both ended up needing all new valves so i went 2.02's needed to be faced and so on.
