Opinions please, if you have run 63/75 compounds

06towrig - I went with TechLine coating. Same coating that's used on STEED manifolds. Went with a SourceAutomotive.biz s400 support and built (x3) a customer hot pipe. Only Action photo I have. First start Twin marine pumps.

Also, you where able to fit your wastegate that tight??

yes wastegate fits perfect with half inch spacer,

setup is now finished and in truck, but of course the trans lasted 1 day with the new setup, just my luck
 
Looks good, I have a couple questions:

Where did you get that dual plate primary mount? or did you make your own?

Random - How long is the straight section going from primary to secondary inlet? 6-8"?
 
I have 10 of those plates, I sell them.

I'm not sure how long that piece is but 6-8" is probably close
 
Great fab work! Is there anything else supporting the primary? Or is the plate the only mount it uses?
 
The plate is the only mount, it is enough, I have run stress analysis with a load of 50lbs and it is completely within the yield strength of the steel used.

I've seen a plate like that from another vendor. I intend to build one. How does the manifold do with the added weight?

Well I can tell you that the steed speed Is not going to break, but I'm not sure about a cast stock manifold since they tend to crack on their own.

I supported a small set of twins off the manifold, it was an HX35/HT60 setup so less weight than your s363/s475 setup, this was the result:

That's right, all (6) tabs broke off the 12-valve head. Notice that the stock manifold didn't break. There were other factors such as over-torqued exhaust manifold bolts that could have played a factor, just sharing my experience with manifold-only supported twins.

This was my one-piece manifold supporting flange:

Hopefully your results will differ from mine, maybe the stronger CR head will hold up?
 
Blue I cracked a head the exact same way on every cylinder running a single s363. I bet we torqued the manifold a little much. That plate is sweet 06 tow rig! How much that set a guy back.
 
I really like that plate you used to mount the turbos.
 
Thanks big blue! I'm hoping yours broke because of the "ears" on your head had stress concentrations in the radii, the 24 valve head is like bolting into a solid block. Maybe it will hold up better, ill keep you guys updated
 
I have three turbos hanging off of a stock second gen manifold on a commonrail head and haven't had a problem...knock on wood
