On a buddy's setup, on a built motor he put down 179 (9psi) and then he switched to an ebay/ssauto ramhorn and made 237 @ 9psi. and thats the only thing he changed. So just keep that in mind, they flow like ----.

Yeah, the HF ports are super tiny.

I'm not a big fan of hp per psi nonsense, but when efficiency falls off hard you are usually running into a bottleneck. I'd say you won't see more than 275-ish on a ported HF.

A log is perfected when installed on a CRX.
