Has anyone installed and run a Mike Graycar ported or magna ported intake plenum on a C4? Has anyone run the plenum with along with the siamesed SLP runners?

I have to leave the heads, cam, i.e. the whole engine stock, but can do pretty much as I want to the intake (no nitrous or turbo/supercharger) and the exhaust of my C4 and remain in SCCA BSP.

It isn't that expensive and was wondering if anyone had real world experience. I would like to continue making power for a few hundred more RPMS, not lose any torque and perhaps gain some HP.

Read a lot posts but haven't actually had anyone say I installed and ran one and liked it.
