I need to make a dual 3'' merge for a T6 undivided Flanged Turbo.

Looking for options, ideas and pics of what you have, know of, or have made.

Any info is appreciated.
Thanks in advance.

Saw your thread on YB. Do 2.25 or 2.5. Its plenty for what your doing. Its not like an NA build, you want to keep the pipes small to keep the velocity fast.

Thanks for your input....But I think Ill stick to my plan. I dont want any restrictions....and since its on a Drag only vehicle....Id say itll work fine in a 3" application. But Ill take pics of 2 or 2.5'' as well....Ill just apply it differently if I see something I like.

Do what you want but you'll actually have BETTER performance with smaller pipes.

I might....But I cant see how considering Ive been told I will be restricted as it is with the Turbine....so I definately dont want the piping to be restrictive at all.

3" cross over is a bad idea. Why do cars making 2500+ hp only run 2.5" crossovers.

Here is a good read

3" cross over is gonna make the turbo spool slower and have slower responce.

OP, another good way to look at it is that 2 2.5 pipes merge perfectly into a T6 flange once you square the ends.

So using 2 3" pipes actually gets you a bottle neck at the turbo. Also, much of the turbo magic is the heat energy. Larger plumbing = more surface area = more lost heat energy.

But if that still doesn't convince you, well, some people need to learn the hard way.

I will be using 2.25 pipes with my 390ci, dual wig's and a t6 turbo (1.32 hot side), with my build.

10's @ 4900+ pounds....and thats not what this is for.
(and for the record...Im only second Quickest now, need to update my SIG i guess)
I like how youre trying to be a smartass though.

You're wasting energy, and efficiency using that big of a pipe. Wasn't the limitation for 2.25 pipes something absurd like 1800-1900BHP?!

Here's a picture of my 2.5 with the merge into a true divided flange. Twin tials



Do 2.5" Max......

And when your done reading that thread, follow the link to the thread on YB, "**** it, turbo charging 102....."

When you've read that, then come back and say, "****, i guess all these people were actually trying to help me."

Best of luck

Also, Guys, help me out here, who was the guy with the black murdered out ws6 370" with a gt91? or some big turbo? He rebuilt his turbo kit because he stayed the course with 3" and had some of the worst spooling trouble. At the track...

GueSS Who

3 in is way to big. redo your plan

I respect you doing what you want to do vs listening to all the cookie cutter stuff everyone else is doing. Here's my 2.5" merge to a t6 open flange..

ws666 i think was the black t/a that JAx was referring to. He did 3" and went down because spool was slow. Do what you want, but you are posting in an informative forum and looking for help. We are all suggesting 2.5 or 2.25.
