I have always thought that the the CAI would be better due to getting colder air than the short ram. However, the short ram will likely have less turbulent air IMO because of the straightness of the pipe.

So which is better in terms of power? Can anybody back their claims with dyno sheets?

Thanks

 

A cold air is better. I doubt anyone would spend money on dyno time to prove this though. Try looking at AEM's website and see if they have dyno sheets.

 

Intake temps matter more than "turbulance"

mandrel bent piping doesn't effect air flow much at all.

 

I like my sri...no worries about water getting in there w/ my setup
plus makes the vtec "BAWAAA" like hizell y0

 

search is a very powerful tool in a forum

Hmm so on his "nowhere near stock" car the CAI gained nicely especially in TQ, hmmm...

Has anyone purchased those cheap CAI's off of ebay? Any reason not to?

 

i bought one of those ebay cai, and as far as i can tell, it's just as good as any injen or aem cold air intake, for a fraction of the price. only thing i would do if i got a cai from ebay, is buy a diff. filter.

 

just spend the extra money and get a cai. Cool air is way better than warm air.

 

search in here after your not a trial user anymore you'll find better quality stuff in here usually for a better price sometimes. ive seen them go for as cheap as 50-110 bucks used http://www.groupbuycenter.com has them for 160 new

 

OK thanks, I think though the ebay kits for like $30.00 are worth a try anyway, I will likely be getting rid of the Z6 next year I hope, so a new one will be needed anyway.

Thanks guys a CAI it is.

 

I have a aem cai in my del sol and am going to be dyno tuning it next week. Since I have a $22 ebay intake sitting around I'm going to compare the two after my last run, I'm curious too, but I'm thinking the dyno won't be able to reflect actual road conditions where the hood it closed.

 

Ok, there are reasons why quality costs more.

1. AEM/Injen and other companies actually do research, not just bend a pipe so it fits. They have a size matched to the TB and engine to flow the best for the most power for that application.

2. Construction. They use mostly aluminum because of it does not conduct heat very well, and they are normally mandrel bent which helps with air flow and does not restrict it at all. They are smooth bore pipe which means they dont have a seam through out the pipe. And usually have some sort of ceramic/heat resistant paint/coating to help protect them

3. Quality air filter. They use a true K&N filter. i dont know if anyone has looked to see how much replacement filters are, but they aint cheap. Even my T1R intake came with a crap filter (which will be replaced as soon as possible).

Just some thoughts... Also the debate between cai and sri has yet to be solved. I personally dont believe the air temps are that different unless you have a duct allowing air to get to the filter in your fenderwell....

I am goin with the T1R (j's racing style) I'll post a review when i get it installed

 

I think DC's website has Dyno numbers for their Intakes ... you might wana look there

 

You'll find it hard to get real dyno numbers off a CAI vs shortram. Remember, the idea of the CAI pulling in cooler air happens while driving. Which is a time when ALOT of air is moving around the car, on a dyno you have the hood up for runs usually so the shortram gets more air(cooler) then it should.

 

SGT and a few other tuners have posted regarding this issue. Physics tends to promote the SRI providing better overall gains, especially top end and throttle response. The downside being the likelihood of heat soak. Temperature changes can dramatically effect the charge of air. However, if you can find someway to inclose the SRI (i.e. Mugen, Comptech) or make an efficient heat shield these losses would be negligible.

Some people have even measured the underhood intake tems during runs to see what kind of temperature difference occurs between a SRI and CAI while at speed. Some have reported such small differences that the difference be minute if at all, while others have found that the CAI does pull significatnly colder air.

Check out the ITR Forum for more details.

I have cold air and i went through 16 inches of water on a highway out here that flooded my car is lowered and you cant fit a coke can under it and i have no bypass valve, car still runs great cept the *** smell in the inside cuz it flooded a lil, I bought my cold air intake of EBAY for 50 bucks shipped, its OBX and i felt a difference, they wouldnt make cold air intakes cost more and stuff if it didnt make a difference. Hell read mags they have those dyno charts in there all the time. like honda tuning or import tuner cant remember which one.

Unless of course the company just wanted to make money. I've never heard of a company making products and marking them up exponential to make money .

Magazine, and manufacturer dynos must all be taken with a grain of salt. Remeber, that the manufacturer is selling something, and that the magazine makes money for advertising.

If I had enough money, I could call Import Tuner, place an add with an excel created false dyno sheet, take a crap in an engine and stamp my ad "100% Guaranteed", but that wouldn't mean it works.

If I had a short ram, I'd do a dyno test.
