fast68plymouth, based on your story, you and your friend don't have a clue what the SP2P was designed for.

Newsflash, not every after market intake was designed for drag racing, re: high RPM.

The SP2P was made during the gas crisis, when everyone was trying to squeeze out every last MPG from their engine.

It was designed for low to mid range, NOT high RPM, so, it falling on it's face over 5,000 RPM is expected.
