and... there you have it! Welcome.

Not yet, I'm expecting the 500R-SP end of this month.

well, i don't know much about rotaries, but i made a manifold recently and thought i'd post it up to get some feedback/critiques. i also posted it in the single turbo forum.

downpipe to follow.

 

That's a nice manifold. But the flanges look pretty thin. Are they at least 1/2"?

 

they don't need to be thicker than 3/8".

 

So this is your first rotary manifold then?

 

yes it is. all my flanges are 3/8". i've been selling 3/8" thick flanges to other fabricators without any complaints so far.

 

might be able to get away with it ... but because of the rotary heat ... you could potentially warp them. An extreme video but should tell you how hot they can run you can fast forward to 1:55

More specs on that turbo (looks like a turbonetics t70) and what car is this going in and what are you gonna be using it for? Also, what size is that wastegate?

thanks!

 

The rotary pushes far more exhaust heat then piston engines. Under boost that manifold will run white hot. Cruise EGTs are around 1600 degrees. 3/8" is really pushing it. As Sam said it may hold up, then again it may not. You'll find most if not all of the aftermarket manifolds for rotary use are 1/2" or larger.

 

Damn nice manifold, one of the nicest I’ve seen in these parts!
Looks like some nice quality stainless you have used, I’m sure it will stand up, good job…

 

wow manifold looks ****ing sick. those are some sick fab skills. i think the thickness should be fine. although they do run extremely hot.

one other thing, is that 3/8 cold roll by any chance? cause if it is then there should be no problems.

 

wasnt there rx of ontario before?

 

i've seen that video before. that is a pretty extreme case. i don't think this manifold will see more than 400hp so i'm sure it will be fine.

 

it is a tial 4 bolt 38mm wg. not sure on the turbo, it is an old turbonetics t4 of some sort.

the car it is going in:

 

Jesus man, nice job on the manifold, and the car!!

 

who's car is that anyways? and where is it located?

 

Beautiful car. Ditch the 38mm wastegate. Buy a 50mm +

I like the porschesque look...

 

hey Aaron... i know you

 

Superb 'weldmanship' and beautiful car.....great work

 

i think the wg is a 46mm, but when i measured the flanges they are 38mm. i'm not sure how tial designates the wg size, maybe it is because the valve is that large?

That is the best manifold I've seen in ontario! Nice work.
