Yes I am running a big high mount. Efr 8374 to be exact. Legally, as long as the pipe is secure it is legal. The object is to start this thing at 380 to 400 awkw and go from there. Assuming based on area and potential cfm flow I could see how it would potentially work with higher power levels, thus would be beneficial to buy one intake pipe and fit it, then go through 2 or 3 setups to alleviant better airflow from restrictions later down the track. I also have custom pipe work needed to be done too. You in qld Scott?
