Finally bought these while in the US. Slowly building intake.

Those bends look so cool! I’ve started having a fascination with fabrication since I started working with sheet metal in school. Are you going to harvest a flange from an old intake or have one cut? Any idea what the final design may look like? I always disliked ones like LR.

It also makes me shiver to see calipers split. I heard that was a bad idea, no?

The caliper mating surface is untouched.
I would guess the problem comes with changing that face.

As far as the plenum neither will be like the LR design.
They will differ slightly on throttle entrance to see how they compare to each other.

I will create a cad file eventually.

Will cut a new flange as it’s super easy to do and will keep the injectors in the exact same position.

Looks like a fun and cool project! Are you a TIG welder and is that all aluminum? Do you access to a flow bench to make sure all 4 runners are delivering the same flow? Or maybe some homebrew leaf blower flow bench? Either way, very interested in following along and see how it turns out!! Thanks for sharing it here!!

(p.s., where did you get the bell-mouths?)

The bellmouths were machined at Fidelity Machine and Mold here in Calgary.

It’s my friends machine shop where I dropped off the lifters.

I will tig weld.

They are the same runners Refresh951 used.

As far as flow bench I’m not sure. I would prefer to play around with tuning on the car. The runners of course will be equal length and port matched to the cylinder head.

Both intakes will have different plenum designs/shape

All 6061

You will need a flow bench to work on each runner to balance flow between them when you will be shaping the plenum.
