SLP runner ports?

Does anyone know the daimeter of the plenum to runner gaskets for the SLP aluminum runners (the ones that are siamesed at the plenum)?

I'm porting my plenum and don't have a gasket set handy to measure.

Re: SLP runner ports?

diameter of the SLP ports are 1.66" stock is 1.40"-1.47" i believe. the tops are siamesed tho... so it looks like the sideways 8 or infinity symbol. the runners themselves are 1.66" they are just hogged out in the middle alil for the first 1"-1.5"

Re: SLP runner ports?

I would suggest getting a set of gaskets. You use them to outlined the material to be removed. With out them you will be guessing.
