My DIY Short Ram
With $8 worth of aluminum tubing and a $45 K&N filter, I made my own SRI by leaving the stock intake tube in place to accomodate the IAT and other sensor attachments. Throttle response is definitely better, the car pulls harder -- really complements the Hondata and header upgrades I did recently -- and it was about 75% cheaper than an AEM SRI or K&N Typhoon.
I'm planning on doing a full CAI using more of the same tubing (3.5" o.d. 6063 aluminum) and a couple 45-deg elbows. The entire stock intake is removed, including resonator, etc.

nice work! 
i think having a CAI setup with sharp 45 degree turns wouldn't be the best for air flow. If you going CAI mayaswell get the injen or something... they are only a couple of hundred arent they?

Of course, I'm a commodity trader so what do I know? You're right that the aftermarket CAI's are only $220-$250 -- I'm mostly just having fun with doing it myself. Kind of like changing my own oil
. Thanks for the compliments!

K&N's Typhoon looks like it turns 90 degrees, while Injen's RD1430 looks to have two 45-deg bends. The latter made more sense to me in terms of smooth airflow so that's the design I'm "copying". Also, in terms of high-rpm flow the DIY design is about 1/2" larger pipe than the aftermarket. It necks down to the smaller throttle body bore using the stock intake pipe's taper from 3.5"i.d. to, I think, about 2.75". The trade-off of a large pipe is that, for any given volume of air, the velocity of the intake air is slower but I think that is somewhat overcome as the larger volume of the 3.5" pipe accelerates as it goes through that taper and into the throttle body.

Just an idea to maximize the effect on the SRI...
I have done a SRI on my other car and fabricated a heat shield and cold air inlet to draw fresh air in. They keep the temp down in that corner where the filter is. The angle of the inlet opening is important in drawing in fresh air.

i converted this sri setup to full cai (pics in this thread) and it works very well, a little quieter than sri but deeper tone at wot. if possible, i want to dyno in both modes but that depends on how much time i want to spend removing and then reinstalling the filter.
either way, i'll post a cai dyno on az for sure.

What a tease. Why not show all of the lude????
