Anyone know where to source the bare plenum flange that mates to the motor? I've got some 316 stainless and a tig laying around and am going to work on fabricating a complete plenum out of pure boredom. Thanks

I realize there probably arent flanges out there, so i may have to mill one out of stainless on the cnc, if thats the case does anyone have a source on mounting dimensions of the intake runners to the motor?

Thanks

 

Find a friend with a spare lower or Kinetic manifold you can borrow. That probably the easiest way.

 

Yeah i realize now that the oem runners being cast makes it difficult, im taking the upper and lower off this weekend while i fab my 3" canister, and taking some micrometer measurements and hopefully will have all the measurements inputted into solidworks by next weekend. I have a 3 axis cnc in the garage and a couple lathes at my disposal.

Im planning on trying a few different designs for the runners and the plenum itself, one with velocity stacks and a sort of split bank collector, then one with velocity stacks and a solid collector. All out of 316 stainless, should keep the plenum nice and cool compared to the aluminum oem design.

Then by the time im finished with the plenums it will be perfect timing to get the car dynoed and tuned(month). Im hoping for something cool, but if not it will still be a fun project.
