We like to share what we design. This has not been tested yet, but should be shortly. So don't go building it without your own testing.

It is 1/2" thick, and built for 1-1/2" schedule 40 pipe.

 

5/8" or bust.

 

1 1/4 or bust.

 

2"
and bust anyway

 

Props awarded, if I get a chance I'll laser the head side out of cardboard to confirm fitment.

 

Looks good. Yours matches my head scan data perfectly.

 

I guess I've been living under a rock. When did 1.5" pipe become the manifold size of choice?
Definitely not a fluids engineer so I won't try and claim one is better than the other, but I'd have to have a good reason to build a manifold with 1.5 instead of 1.25.

 

it's not. use 1.25 like 90% of the rest of us. he has plans for ALLOFIT in 200 years

 

Great question. I used 1.5" sch. 40 because it matched the factory port size when I smooshed it oval with a press. If you're making a fancy flange with a loft between the oval and round cross section, I'd think about doing it for 1.25" pipe too.

 

I used 1.5" because that seems to be the common pipe size. My current manifold is built out of 1.25".

I'll see about getting a 1.25" drawn up. 1.25" shedule 40 is pretty small ID though compared to the ports.

Oh now I remember why 1.5". ACE Race doesn't have 321SS in 1.25 schedule 40.

 

Bruh. I bought a turbo and rods.

Like 100 years minimum.

 

deezum's is drawing up a version for 1.25" schedule 40 also if you are so inclined.

 

Aaaand damn that guy works fast.

Nice! Nothing like getting free stuff. Thanks for your time guys!

 

If you use 321 stainless I wouldnt be afraid of sch10.
