I Know This Is Stupid

[RSX-S777]

I think kicker implied something awhile back about PVE. At a certain point, air temperature is nearly nullified by sheer volume of air induced. The CAI produces great low-end response due to cooler air temp. I think this is why most people swear by them. They can feel better response within the most commonly used (lower) rpm range. At higher rpm, the SRI matches and slightly exceeds CAI gains before evening up again due to the fact it is simply able to induce a larger volume of air (physics/dynamics). So basically, each intake creates different peak-volumetric efficiency. You choose a CAI to peak at a lower rpm, or a SRI to peak at a higher rpm. Ironically, after a certain rpm (albeit a high rpm), both intakes are dead even as far as gains are concerned. They are both different, and both have their pros and cons...so why argue?

tran_nsx thanks ,trying to help when i can

i did read the fine print from what i understand they are saying is that the RAI would become hotter in stop and go which mean it would lose some of the hp gain but also if you look most of the RAI are making 2-4 more hp than the CAI so the 2-3 hp they would lose from becoming "heat soaked" would make them about the same

i also undestand that when doing dyno pulls your not getting the same amout of air that you would be if you where driving at say 60 mph so the CAI could make more power if you where driving and not sitting but then again so would the RAI becuase of the temp drop from air moving around in the engine bay i havnt done a test or seen one for my self that shows how much the temp in the engine bay would drop from driving at different mph but in the long run the small hp gain from the two is not going to be missed 2 hp is not going to give you a better e/t or make you beat the v8s

I've had both. Sold the AEM CAI and bought a cheap ass Ractive (3"-5"-3" tube SRI), and K&N filter.You can tell night and day the difference.The CAI was definetly better in lower rpm range, but I got better results higher up in the rpms wit the SRI.I like it better then the CAI. Also, it was $6 off ebay, lmao.

RAI are not freeing 2-4 hp more than CAI. They are close to even in the upper rpm's and the CAI frees more in the lower RPM's CAI also frees up more torque. I have never seen any dyno test showing a RAI freeing up 2-4 hp more than a CAI!

hold up. u can feel a difference in power by the addition of 2-4 horespower? yeah ok . the only difference u can probabaly tell is from the sound and thats about it unless u compared it on a dyno. no more bull please, and yes i have own both a sri and a cai. the sri intake was louder due to the fact the intake charge at the induct is far closer to you giving the impression that its making more power at high rpms.

for everyone else who argues that this is pathetic to argue about 2-4 hp, i do see ur point. however, there is a bigger picture, 2-4 hp is pretty measely, but in addition to the other mods accumulated, hp can be quite different from stock, ahh hopefully higher i might add . yes thats right not all mods free up hp. example, after the engine is warm up, a sri can actually make less hp than the stock intake because of it taking in hot air. again, the last test were done when the engine is cold, which shouldn't even count at all.

im talking about the numbers here not lower rpms gains look at the link i added you will see what im talking about better yet i'll post the numbers so everyone can see
Name RAI CAI

AC Autotechnic 144.7 141.6
AEM 144.5 (V1)142 (V2)141.9
Comptech 142.7 142.9
DC 144.5 143.3
Injen 144.1 (1)140.7 (2)143.7
K&N 139.5 142.9
pro 1 (cotton) 143.4 141.9
pro 1 (foam) 142.7 NA
Weapon R 142.7 NA
Iceman NA

i underlined the winner in this test just so this is clear im not for the RAI or the CAI im just showing dyno number that where on this website

tran_nsx i see what your saying about the way this was tested the fact that the engines had time to cool down could make a differents
but still i say that the 1-3 hp you will lose with the RAI when it be comes "heat soaked" will still put it around the same hp that the CAI are making

also the reason i post that site was not to prove that the RAI makes more power just to show that the 2 hp gain isnt anything big and for people not to be worryed about the small gain in hp

I would like to see the site those numbers came from! Not nessisarily calling bull, but every dyno test I have seen has shown opposite. Is the car warm when these numbers were taken. Also higher peak power is not always better. Look at the power curve, and the torque curve. You have to see what kind of power they make throughout the whole power band.

here check this out, another comparison test between a cai and a sri to get a general idea of each's potential.

something alot of yall are missing, is most of the tests the anti SRI guys are posting up are using way to small of piping, while most CAI's tested are almost 2.85-3 inchs i diameter, the SRI they tests on that last web site was only 2.5 inchs, thats the main thing right there, not hot or cold air but the ID of the pipping used.... straight from that website:"The short ram is your typical 1.5 foot pipe that is about 2.5 inches with your K&N filter inside the engine bay."

scallywag i posted to website one page 2 but here i'll post the link againhttp://www.tprmag.com/issue/1/1_intakes.shtml

i know that peak power isnt what really matters it is just what we are talking about

man , i wrote a decently long and knowlegable post on why these intake specs are generally these specs, but the server was freaken too busy so my post never got through.

to make it really short, bigger isn't always better. example, compare a cai intake for an ls model and a cai from a gsr model of the same year. u will discover the ls will have a wider diameter. but shouldn't the gsr be the one with the wider piping to get more air so u can get more power u say. no, it doesn't work like that. too much air being swirled into the engine will actually hurt performance. why? because too much air coming in at a different consistency will not let the vtec mechanism work properly. this is the same reason people complain about turboing there gsr's. again go see for urself, i believe the diameter for aem's b18b1 models is 2 and 3/4 inches, and the b18c1 is 2 and 1/2 inch. of course u can create ur own intake as u please, but trying to out perform aem and the rest will be a difficult task. these companies are known for making the best intakes which is why other companies utilize these same specs for a reason. why screw it up?
