I bought a holley hi ram for my ls3 project. My heads are cnc'd and I've seen sheet metal intakes put out some serious numbers. So I was wondering on boosted motors if I'd benifit from doing a port to match and smoothing the runners and my be the whole inside. Think it's a smart idea or just wasting my time here's an example

Boost is a measurement of restriction. The better the flow the more power will be made at less boost. That being said, the intake will easily out flow the heads as cast. Reason being there are no bends or valves in the way of the flow. Not sure if I can help you tho because I would port it anyways. Heck I hand ported my 317s knowing that they would make 1000+hp untouched. That was my goal yet I ported for peace of mind. Think of it this way if you port it first, you will never know if it was needed or not. It can only be a waste of time if you know it wasn't needed. Lol

That is a good point do you think it would hurt the idle or drivability ? On my bbc chevy with a sheet metal intake it doesn't idle worth a crap.

I am no expert, but I would say cam selection would play a roll in the idle quality. As for drive ability, it depends on the car weight, gears, converter and tune.

That intake looks familiar.... the biggest gain is going to be porting the inlet and short turn

Those things look pretty good on the inside. I'd say a port match and give it hell.

That's not my intake it was the only pics of one I could find ported that's someone's ls7 intake on here. Well I guess since the snow is shitting on us all I minds well stay inside and port and polish
