with a short ram, your less likely to suck up water. here in FL, when it rains certain streets usually flood so having a SRI can save ya from a lot of close calls.

 

Not exactly true. Short rams will make more power at a higher RPM. CIA's help with midrange.

When it come's to Short rams, Just "hacking" some piping may or may not help! Pipe diameter and length have a lot to do with power gain. I'm not an expert, I just read a lot

 

this has been a hot topic since i joined. ha

i guess b-series vtec engines would rather get air in asap rather than take a little extra time/effort getting in cooler temperature air. in and out. hopefully you already know vtec is just the timing of the valves, so more air and fuel combust since the valves stay open for longer. also i already mentioned that there is good airflow under the hood, so the air is decently cool.

for example, on a non vtec b18 engine, CAI's start losing ground to the SRI near the upper RPMs. this is because the CAI cant supply the amount of air needed for that RPM/pipe is too long. since vtec is all about getting air in and out at a rapid rate, it makes sense to slap on a SRI onto a b-series vtec engine. imagine NA b18b and b18c1 engines. at 5000 rpms, the vtec engine will be sucking in more air than the b18b, because vtec allows more air to come in through the valves. i dont know about other engines, but a b18c1 has vtec engage at 4400 rpms. you hear it and better yet feel it. midrange.

there have been one or two tests done on the same car, same day, same dyno with a SRI and CAI that i have seen, and the SRI outperformed the CAI. on a B series vtec engine of course. im sure it varies by engine.

search through HAN, find it. then read your penis off. :boink:

damn, who was it. it was LT when he had his integra or schmoo or one of them smarter guys that said that SRIs outperform CAIs through all RPMs on b-series vtec engines, which sent me to search. then i changed my mind about SRIs and CAIs. for b series vtec engines, at least.

havent had the chance to read over this, in a hurry, hope it makes sense
oh and this is turning into another sri vs cai topic, sorry if i got ppl off track.

 

hmm....i've had AEM CAI for a while now and i haven't seen any problems.....granted i had to cut off about 6" from the throttle body end and force it into place cuz of the goddamn supercharger...personally i just like cold air....i've only driven short ram a few times and it's not a super huge difference....but when we're only looking at a 2hp diff if anything....who cares

 

That's pretty much it. Either way you go, you're not gonna find much of a difference. IMO, the only difference is the chance of hydrolocking your motor w/ a CAI.

 

I think it's all a matter of what one wants for thier car. On my old SOHC
(D16Z6) civic I replaced my CAI with a light speed short ram. The short ram just felt more peppy. Yeah your right, No need to turn this into my SRI is better than you CAI.

 

In an effort to completely obliterate the percieved difference between CAIs and SRIs, one can always duct cold air up toward the filter on your SRI.

I did this on my GTi to ostensibly reap the advantage of a true CAI without the fear of hydrolocking.

That said, I never had the chance to measure intake air temp at the filter to see if the duct made a difference at speed. h:

 

well now that ill be going turbo i wont need my CAI or my old SRI. if anyone wants to by them. look for them being sold soon. thanks for the info guys!

 

haha when your from southern cali....hydro locking is rare...just dont floor it going 30mph thru puddles and you'll do fine

 

isnt it a bitch to clean the filter? doesnt it get dirty faster since its right by the wheel? friend has a CAI and it whistles like crazy, i love the sound. but his filter is dirty like whoa

during your time with your CAI did you ever hear a rattle..??

damn this topic makes me worry about my exhaust rattle..maybe im digging a hole in my exhaust every time it warms up (whenever it rattles) =/
