Check out this manifold I built! RB26 Stye baby ;) hell no 56k
Just some fab work I did over the last week, I spent 4 days (8-10 hours each day) on this single manifold in coming up with the design and building it
This customer is shooting for 1000hp but is worried the gt42r will restrict him so when he maxxes this turbo out the is going over to gt47r

Ok as to flange being warped...
Yes it is but check this
tubular manifolds can have flanges warped and it not be much of a deal why?
Well because the runners are so long they have alot of flex in them
I put this on the head and yes it was warped by about 3/16 " on each end but when ever u put a nut on the studd and start tightneing it pulls flat very easily
I have been building manifolds for 3 years and on every singal tubular manifold I have sent them to the customer with the head flange like that and zero customers have had any problem
I might accosinally get one that is paranoid call me and say it was but what I tell them
" bolt it on the head and tighten it down just as it is supposed to be, if you have a leaking issue (about 1 in every 100 manifolds actually leak) then get a $20 mr gasket 1/8" thick copper gasket and I gaurantee it will be perfect"
Now check this
I have milled several manifolds flat in the past but there is still the internal stress of the manifold, by the time the manifold has been deliverd (shipping is usually 3-5 days) the flange will be warped again because of the manifold's internal stress so what is the point of flattening?
On manifolds such as logs and short manifolds this will not work because they are so small and compact that they have no flex to them at all, but on every tubular I build (top mounts, ramhorns, min ram, etc) they all pull flat when put on the head as a final resort if they dont pull perfectly flat is I cut slots on the back of the heade flange (not all the way through like full race because then the internal stress of the manifold makes the pieces move by like 1/8" and you have to ghetto oversize allt he bolt holes and then you have poor primary alignment on the head) but cut so that there is aprox 1/16" thickness left this allows it too tighten up on the head extremely easily (even log manifolds will flatten out on the head if you do this trick) it takes about 5 mins to cut these slots as opposed to 30 mins to an hour to mill it flat and it will still warp by the time the customer recieves it.
Anyone that actually builds manifolds already knows all this that I sasy though it is just the customers that dont know how it really works lol

Yah if I was building an all motor header and wanted a round collector I would do that but with the way we did it here it perfectly matches the t4 flange

I will deffently keep that as a compliment coming from you
I guess I am doing something right first time you didnt critize my work
lol thanks for all the compliments
