Re: Need opinions on problem. Had a manifold crack but really strange.
 

You need to put cuts between each exhaust port.That will help to relieve some of the stress of expansion and contraction.Thicker material in your case will just pull the exhaust manifold studs out of the head,and that would be bad.A longer runner disperses the expansion away from the head so the problems are not as bad.Thats why the big guys quit making log manifolds.

I know why it cracked, I installed it. >:D

Makes a lot of sense. Thanks.

Looks to me like dave is distributing SS Autochrome Products as his own...

Re: Need opinions on problem. Had a manifold crack but really strange.
 

Just had to throw that out there Dave, But on a serious note, the cracks themselves even look strange and the way they came out on the bottom of the manifold. My guess is that mother nature had alot to do with it, being that those crazy minnesota guys live in -500 degree weather. Your welds are pretty damn solid on everything ive seen

whatever it takes to make a quick buck >:D

Re: Need opinions on problem. Had a manifold crack but really strange.
 

that is really weird that it just cracked straight across like that. the upward force theory sounds most reasonable to crack it like that. it doesnt look like it the manifold was hot when it happened either, just looks like something pulled straight up on it while it was cold. csaddict sounds like you're a good businessman, keep it up

Re: Need opinions on problem. Had a manifold crack but really strange.
 

my opinion is the cracking is in the wrong location for it to have cracked, not to mention the cracks are lifted and the pattern of the crack indicates it was caused from a upward forceful motion.

theres also zero traces of carbon, as i zoomed in to about 800 percent on photoshop and saw nothing.

there is no way to not notice these cracks while driving, they are so large and ------ aprt your turbo would not even spool.

i say he jacked up the engine by the manifold ad broked it, and now hes fishing for a new one. :-X

Josh, would you say the same about thing if it were trance? DoubleA is almost a twin personality of trance, and you know how that goes.

Make a new one, move on.

yup, looks like he broke it on purpose, so he can park his car and wait for the same mani :l
