I know there is no real performance gain from porting an intake on a stock top end motor, but do you guys think it will actually hurt performance?

The reason I ask is I want to get my intake powder coated, and was thinking about having AI or LE port it while it was off. Reason behind this being I'm eventually going to run an AI or LE heads/cam setup on my car, so I know I'm going to want a ported intake at that point, so doing it now would save me a couple hundred bucks down the road.

I've seen and heard claims that it isn't "worth it" on a stock motor and that it wouldn't give you any gains, but I didn't know if it would actually hurt performance on a stock top end?

Kind of a stupid question, I know, but just wondering because I'm not positive.
What are your guy's thoughts?

I have an AI ported intake. Is it hurting or helping? Who knows...but it's doing me well so far, IMO.

No doubt, your car runs great and I am dreaming up a similar build for my car in the future. But I'm still wondering if anybody has any documentation or experience with ported intakes on an otherwise stock top end?

I'll probably just end calling AI or LE here next week.

The stock intake is damn good. There's an article floating around the net that compares a ported intake versus a stock one on a modded setup and it shows little improvement. It's unlikely to hurt though.

Kind of what I figured too. I'll call up AI and LE next week and see what they think.

talk to STOCKTA, he knows his **** about porting intakes and might even of been doing it longer. that super stock or w/e intake he did looked shexxy!

Depends on the porting and the heads. Make the intake ports larger than the head ports and you put a shelf in the middle of the combined port.

Explain?

if the intake port is bigger than the intake port on the head you'll end up with a shelf where the larger port hits the smaller port, more turbulence, less airflow...

Oh I read him wrong. I thought he was telling him to do that! That was the question, WHY, not what.
