I would be very interested to find out as well.

 

tnaks for thw bump

 

1.5 in sched 10 ss long radius 90's are what i use to make all my manis.

 

thanks for th info, if there is any others using different material please le me know.

 

I am doing mine in 1-1/4" schedule 40, which has an ID of like 1.51". 1-1/2 sch 40 is like 1.67" or so.

 

1.5 ID is like a 1.9 OD with schedule 40. Anything smaller and your gonna have gaps on the horizontal ends of the ports.....

 

I use 1.75" o.d. .065" wall tubing and when shaped to match the port it fits perfect.

 

I was just going off some stuff in my head. I remember it being a bit more than the general figure, just not knowing by how much

 

wowo i am so confused, people use many differnt things. why not use same material as the collectors?

 

I was just talking about the setup I had used on my car. Slightly different engines

Not me .I use 1 3/4 16 ga. and I hit the end of the tube with a rubber mallet then it fits the port perfect.

 

is than strong enough for turbo manifold? do you brace it?

what is a better material/thickness for the turbo manifold? ie: schedule 10, 40 or guages

do you want to retain heat or disperse it?
