3" or 4" cai

3" or 4" cai
I have enough tubing in both sizes to make a cai. I have an aem standalone that's going on the car and making a custom 3" exhaust. Would I see more power gains with the 4" or would the stock tv heads cams etc not be able to move that amount of air?

Going from a larger pipe to a smaller pipe will help. You can even use and should use a velocity stack to help the air flow. I found this one that has a good outer ring to mount the filter on, but there are cheaper ones out there.

I would not use a smaller pipe than the i.d. of the T/B for the pipe that mounts to the T/B

Where have you seen that? I've read and seen dyno graphs that state the complete opposite.
No offense to anyone but if you don't have any proof to back up what you're saying don't post.

Mods? Standalone?
This guy tested multiple setups and his 3.5" is proven to gain more power. https://www.s2ki.com/s2000/topic/909...tepped-intake/
The AEM intake is even a 3.5" to 3"
Im going with the 4" with velocity stack, tapered right before the tb. Might get a bigger throttle body too. I'll post numbers when I get back from vacation.

Lol the link I posted was to your posts, what're your thought on doing the 4"? Im pretty much doing your build, until I feel like buying a turbo and building a mani.

on a stock longblock i would say it's overkill. if you choose to test a 4 inch intake pipe, make it stepped. 4 inch tapering down to 3.5 inch.

My car and a couple of other s2k's I have dyno'd had very large gains going from a 3 inch cai to a 4inch.
once you start making more than 220hp to the tires a 3 inch intake is simply not big enough. Its way easier to hurt power with an intake thats too small rather than one thats too big.
Also, the air filter makes a difference. AEM dryflow always makes a couple more hp than anything else on the market.
