Fix Cracked FAST 90 intake My buddy's 02 Procharged Trans Am has a FAST 90 intake manifold and last week on the backside of the intake manifold it cracked and broke a chunk out of the back. I was wondering if there is any way to fix the intake (plastic weld, epoxy,etc?) or should he not chance it and fork out the dough for a new one? 
There was a guy here that tried to repair a cracked FAST and was not successfull. He was not FI either i'd say the fact your buddy is running boost is gonna pretty much rule out any fixes.

thats what i was afraid of...it hard to bite the bullet and buy another one..esp. since they are a little over a grand all said and done...anybody else got any ideas???
have him look into a Vic jr. or GMMP intake for FI they are great. He can also get a ls6 intake and call it a day.
I wouldn't use a broken fast with boost even if it was fixed. Also Fast used to sell just the bottom piece, but doen't offer it anymore, he may be able to hit up a couple of the sponsors and see if they have one left over and be able to fix it cheaply and fix it right.

The problem with a boosted motor is that the intake manifold will not only see boost, but also vacuum, so it's going to get pushed/pulled and never hold up after being fixed.
I've heard people say that there isn't much difference between the fast and a ls6 intake when you go into boost, so an ls6 intake may be a good alternative.

Devcon 5 minutes 2 part epoxy...make sure to sand and rough the surface up...also 1/16 holes help too if need be...worked great on my intake when I wanted to over port some areas and fill some in... I am n/a though...

ya once you go boosted it really doesnt matter what intake you use, there wont be that big deal of a difference, not like heads, and the fast from what i have heard doesnt stand up well against boost or nitrous when it backfires into the intake, and your friends intake just proved it. if anything i would look into an aluminum, maybe a bit heavier but heavier is sturdier and is more resilient.
