very nice job with the manifold, just to let u know there is a top mount out there, p fab makes a really nice top mount thats equal length

 

Very nice handy work on the manifold. Looks great!

 

it looks like there is a lot of contamination in those welds. you should also think about making a jig plate to bolt your head flanges down so they don't warp on you. if you want cheap flanges i can hook you up.

 

Dang...
Almost looks like the mani I designed and built last year.

 

I think anyone that does their own stuff deserves a thumbs up. But as weiRtech said, there is a lot of contamination and it looks like you used too much filler, but your exhaust manifold flange looks pretty good.

Either way, great job and I'd like to see everything finished.

 

qutoed for truth, wiertech flange on above pic

 

I was going to ask you if you had the flange mounted to a true surface. Also you might want to add some grooves in the flange to allow of expansion. Have you check the surface at this point? I have had a terrible time with a customers manifold someone made him because it warped every time heat was applied. Wish I had the time to learn to build my own. Great job.

 

you are going to get some warp in any flange, but you can reduce it by welding it just a small amount at a time and having it bolted down to a nice heavy piece of flat material.

i've had 1/2" flange warp upto an 1/8" on me and if you tighten it down in the proper sequence on the head so that it is flat, heat cycle the manifold and then retighten everything again while it is still hot the first couple times the manifold is up to temperature it should flatten out. when i took mine off it was glass flat.

i was waiting for the pb special to show up.

 

when welding i bolted the head flange down to the table, and the table is made of 2" thick steel, with an alluminum 3/8 sheet bolted on top, its as solide as it gets.

the flange didnt warp at all actualy, i put a straight edge on it and all seemed nice, i did small parts at a time, and in the pics was only 2-3 little stuff that was left when it wasnt bolted to the table. but i will recurface it at the machine shop next door anyways like i do with all my manifolds just to be safe.

i always do every surface just to make sure i dont run into any problems in the future.

i know i should have cleaned the bends before i welded but i just got a bit caught up, and i jumped that step all together, lol

anyways the fit seems nice, and i will clock the turbo as far away from the manifold as possible, and i will most likely fab up some kinda heat shield.

 

I took some more pics tonight I will post them as soon as I get home
