Good info on stock airbox vs cold air intake

I was at TPIS awhile back and they were testing the stock airbox to see what its limited to. With a gutted air box and some kind of hawks ram air boxes, and a gutted maf, the air box runs out of air around 425 hp. Anything above that you should use a 3 inch cold air intake. June 28th when I go to the track I am going to test both methods to see which on yields better results.

Did they happen to list CFM numbers? I cant seem to find that info for a camaro lid/intake. Just the firebird setup which is totally different.

So what happened? I cant find anythreads with somebody testing both style intake systems. All I can find on here are opinions and no real testing that has been done.

Re: Good info on stock airbox vs cold air intake

I agree with THEGOOSEMAN... everyone says their opinion on stock snorkel setup vs the aftermarket single intake. . We need real test info .. not opinions.

Is cutting the maf screen a good safe idea? People say that you get slightly better air flow but will it mess with the motor?

Re: Good info on stock airbox vs cold air intake

I built my own custom cold air intake with 3.5 inch aluminum tubing, and I did notice a difference in high RPM pull. As for cutting the mesh screen on the MAF, I personally would not do it because, 1) I don't see how you would get more air flow and 2) if you manage to break the sensor they are very expensive to replace.

Re: Good info on stock airbox vs cold air intake

Are there any test results from the stock snorkel air box gutted vs a single aftermarket intake?

Interested in knowing the difference if any... I have the stock snorkel set up in my garage and the single aftermarket intake on the car now... cant tell a difference personally. but maybe if i gutted the stock snorkel set up i would?
