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.

i have SLP.

FTRA is more popular.

thanks for the input
did you notice any difference with the CAI compared to stock?

a little at mid range when air is flowing.

I know I personally have opined on this subject about
a hundred times. You can find a lot more opinions with
the search function, than a single thread. Check it out.

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.

Nice try, but I said lid over CAI/Ramair. I know there is a difference when the stock setup is compared to a lid because with a stock set up there is turbulence, but in a lid/ramair/CAI setup the air is more direct. Lid vs Ramair/CAI is what I'm looking for.

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.

will you see a difference with the taller box?

The suckness of the stock lid is less the lid, than the
silencer. So adding a CAI slot won't really help the
primary restriction.

Yes if you keep the stock lid a cai or undercar ram air won't do much but if you change the lid and put a undercar ram air like FTRA or CHRS1313 system on as well you will gain more mph from the ram air then the lid I think I may have misunderstood what you where saying
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

ugh i really like the look and fit of a stock lid.

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.

I never felt the gains from the slp cai either, but thats whats nice about a g-tech... you can actually verify gains from mods you do!! That way you don't have to rely on your butt dyno lol. with just the slp lid my best was 12.78 @ 117.4... All I did was add the slp cai tube and went back out and ran 12.61 @ 118.4. I know the mph is high, thats not the point... point is it verified a gain from the mod! I bought the lower extension from ftra to make it ram air, but I dont like how it blocks so much of the radiator... so I only run the top part (slp cai) on the street.

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

A friend of mine on here said he felt a lot better throttle response from a ported stock TB, gains will be up to 5hp. Not too bad hp/$.
