I don't know a lot about how functional the ram-air is on my 98 SS. I was wondering how a K&N air filter would affect it? Any info would be great!

Thanks

 

I've heard the ram air doesn't do much of anything. But I know the k&n does add like what 10-15 hp?

 

depending on the mods u already have

 

So the ram air hood does more than look pretty?

 

The car is stock.....

 

If you beleive their advertising it adds that much. A K&N is only good for a hp or two but they are nice because they are reusable, that is the only reason I got one. What I would do is to buy an air lid (if it does not already have one) a smooth bellows (the coupler that goes between the MAF and the TB). Thats all thet you need on this car intake wise for quite a while. Keep your stock MAF untill you reach about 400 rwhp. If you have the extra money an LS6 intake will show some pretty good gains (15-20 hp)

 

Thanks for the info....

 

In my experience, K&N filters do nothing for power. Tested this out on the strip and the car, 94 bone stock Z28, ran pactically the same with either filter, and no filter.The main thing is to have a clean filter, regardless of brand. What helped is fixing the restrictive air plumbing between the throttle body and the air filter. As JD stated, the MAF sensor is plenty big enough for up to 400HP, and a bigger one won't do much except lightening your wallet.

 

What does gutting your cats do for performance?

 

With a modern free flowing cat sized big enough for the power you are producing, gutting the cat will produce very little additional power. Cats were very restrictive when they first csme out, but things have changed a lot in the last 20 years, but old stories die hard. Removing restrictions in the exhaust plumbing will help more than gutting the cat. That is why cat back systems are so popular.
