looks awesome, cant wait to see what power it frees up!

 

that's called turned ... but you probably know that.

 

semantics. meh. metal spinning is a lost art almost. very, very uncommon these days. i do know a shop that does it though. yes turned, on a lathe.

I've used some of those, they couldn't make one as small as I wanted though looks like I'll have to machine some.

 

yeah, making them smaller, i think would be more difficult. because they are inside the plenum, i think you might get away with thinner gauge if they are formed, since they only direct air and aren't structural. i might try to see if i can form some, but i will probably end up getting some machined for the third one. the problem with forming is you have to make a die. if it doesn't work out, all the time into making the die is wasted. i already have a set identical to the set on this manifold ready for #2.

 

I'll make sure to put the manifold to the test

Hope ya make enough of these to go into production
