provided you isolate the pod filter in a whale penis or SRI and provide a direct cold air feed, the issue of heat soak will be negligible. also i wonder how many people running CAIs in victoria shat themselves in the past week? i certainly did.
I think its called the Tsuchinoko CF Intake. The main positives I found with this intake was that the accelerator was much more responsive, looks good in the engine bay and has a very nice and loud intake noise under acceleration. The main problem was that the heat soaking is terrible and even worse in hot weather.
If you are able to isolate the pod filter, results are much better. many guys on the ek9.org forum swear by this. there is a whole thread dedicated to it.
its quite easy to fabricate your own pod filter isolation box with some sheet aluminium, a couple of bolts and rivets and some spare time. it's pretty straight forward.
i went from a stock VTIR integra intake arm with an apexi pod to the simota whale style one and i did notice a loss of response and power down low but gained a small window up high ... the difference is only slight though - the sound is less revvy and more blarey and loud as well
i have fitted a cold air duct to the car and it has made a small improvement on hard acceleration, the filter does get alot of hot air from the radiator fan though
only reason i got it because it was the cheapest kit i could find at the time
im saving for a better/proper cold air intake system - u can get a Fujita CAI kit these days at a good price - best way to go imo, or if u are tight make ur own =p
I bought a second hand injen CAI off another member and I've noticed a noticeble mid-range gain. Initial response is slower than stock which requires some clutch slippage at launch.
Back to the point, an exposed filter in a hot engine bay is inferior compared to a CAI. Basic physics will tell you that a colder intake air temperature will provide more H/P.
Unless you have a decent heat shield, your whale penis will be less effective than a CAI.
Initial response doesn't seem much different from stock, maybe a little slower, but it's hard to tell. Also, my clutch is slowly reaching the end of its life, so could be a factor.
Overall, like I have said before, colder air creates more HP. CAI is the go.
That is, that the molecules are more closely bound by their covalent (electron-sharing) bonds due to the lower temperature which results in less electron-jumping between electron rings?
Bleh, anyway, if the gas is cold it will have a higher density, therefore you get more O2 molecules in the same volume. CAI FTW. Screw SRI, it's just for sound looks ---> FUNCTION > FORM!
