Ramair/cai
I am planning on buying a RAMAIR or CAI system and I was wondering which I should go with. The FTRA or SLP CAI, or even something else? Is there a major difference between RAMAIR and a CAI? Only add-ons are the SLP loudmouth, & hypertech powerprogrammer.

IMO, for a lightly modded car, you don't need more than a lid. I have never seen a test saying that a CAI or Ramair intake makes more power than a lid. I don't think there's a difference. I'm talking at the track, I know you can't measure this on a dyno.
I will eat my words if someone can show me something consistent.

I went from just a slp lid to adding the cai tube. The car picked up a tenth and 1 mph in the 1/4. I purchased the ftra ram air upgrade for the slp cai for 79.00... But have yet to verify the gains with it. The ftra upgrade attatches to the slp cai and directs flow right off the air deflector under the car. The problem with it is that it blocks alot of airflow to the radiator.

Agreed stock silencer and lid are the biggest restrictions and until you change them not else will work good. I guess I'm just taking for granted that every one should have a lid as first or second mod

Stock lid+silencer, no filter, had the same pressure
drop as a screened MAF when I flow tested them.
It's pretty bad. Some people fill the resonator holes
but no data on how much that helps.

I don't have any good knowledge of fluid dynamics. So if the lid and maf have the same pressure drop, are those two pressure drops added together to see what the engine sees. or did GM design the lid to have the same pressure drop as the maf because the motor wont see a good gain with less pressure at the lid.

Just get a lid, put the rest of the money toward something else. I have a FTRA, and I noticed ZERO difference on the butt dyno, nor did I see any mileage gains.
I'm glad I bought it used so I paid about 50% of retail.
Do you have an A4 or M6? Put the money toward a torque converter for your A4, or towards 4.10's for your M6. Those will give you results you can feel.

A ram air system has been proven over and over that it is a worthwhile mod. I did my own track testing last weekend to prove this. I had 6 runs that averaged 12.33@108.5 with no lower scoop on my SSRA (essentially the same as the SLP). Just adding the lower scoop, I gained almost 3mph. Average on the final 3 runs were 12.28@111.0.

I will probably go with the FTRA. Another thing I'm wondering about is a P&P TB.
Any good results? worth getting it done? http://www.s2performance.net/F-Body.html
