It moves 500 cfm. It should be ok. I am not racing the car except a few test and tunes. I did a mock up and moved the brake line up so I got more clearance than before. I happen to have 2 lengths of -6an line that fit will fit it perfectly so it will go there for the time being. I just ordered some 1/8 npt to -6an fittings so the install will be clean.
It is set off the floor by the base. There is 1/2-3/4 inch clearance. It is designed not to be flush preventing air flow. I may install a temp gauge as well, not sure about that just yet.
