Product request - knife edge TIG

Welcome Turbo Steve / AP!

2016 will likely go down as the year of the intake manifold for this platform, and you have a very nice looking TIG available. I was curious if it's feasible to make it even thicker to accommodate a knife edge between runners.

Beveling an edge onto PTFE doesn't sound particularly wise, as I'd imagine that scrawny middle piece could easily get pulled into a runner if there was no clamping force on it, even more so if the IM has open runners. A rigid part like yours might be what the Dr. ordered and preferred to grinding on the head.

Thanks for any consideration!

 

I'm already toying with making some true phenolic intake spacers. The issue is that going too thick and it will be very difficult to set up a straight shot from manifold runner to cylinder head without porting either the manifold or the head.

I'm thinking of making a .250 inch thick phenolic spacer kit that would be used with a stock gasket on either side. You could port match the manifold to the spacer and you should be good to go.

I'm also going to have throttle body gaskets and single runner intake gaskets soon as well.

 

I would think a .250 might be a bit thick. 0.1875 is what i plan on making as soon as the laser is available. Curious as to the .250 thickness. My only concern with Phenolic is if meth injection will effect it over time

 

The .250 thickness is as thick as you would ever want to / need to go. Going thinner is also doable as well, but i am going to test out the .250 first. The word "Phenolic" is used loosely by manufacturers of spacers. The material I am sourcing technically is and isn't phenolic. It has every bit of strength and insulation of traditional phenolic sheet, but has a higher maximum temperature and has proven to be fuel proof. I would share more detail, but it wasn't easy to source.

 

Awesome. I'm used to the Aerospace industry Phonelic. I've used it to make throttle body spacers for v8's. Now I have some digging to do dang it. What are your plans for cutting. Looking at CO2 laser myself, should seal the edges when cut.
