Thinking about cool air intake
I wanna get the T&N typhoon cold air intake but I'm not too sure about it. Will it give performance or haut mainly sound? The price is about 250$ am I wasting my money or is this a small upgrade?
Hey all. I've been a bit of a threadstarter lately but wanted to share some experiments I've ran lately on air intake temps (AIT's). I recently picked up a Garmin which monitors AIT's and have dinked around with various configurations to lower them as much as possible. For the most part, they're consistent with what's been said here already but with a few caveats.
First, I've noticed that the TL is especially sensitive to AIT's. Yes, I know this is already well established around here. But there are several videos and threads discussing the real power output effects of AIT's with some of them stating that it's not as big a deal as some think. With some cars, this may be true. But with the nature of the j-series engines (aggressive timing, compression ratio, etc.) AIT's are a pretty big deal and can significantly affect power output.
My current setup is as follows: Cheapo eBay CAI w/ AEM dryflow filter. Outlaw spacer kit (intake manifold and throttle body). UCM - Ultimate cooling mod.
Short Ram vs. Cold Air Intake - Using a cheapo eBay CAI and an AEM dryflow filter, my AIT's are between 8-20F higher than ambient temps as recorded on the MID. Typical is 10-15F higher with 20F being more common when idling for over a minute. This is pretty consistent regardless of ambient temp (ie. Ambient temp 70F, I'll see 80-85F IAT. Ambient temp 100F, I'll see 110-115F IAT). I've rarely gone over 20F above ambient. For example - it was 95F outside according to the MID about a week ago. The highest AIT I got was 114F when in line at the ATM for about two minutes.
My CAI can convert into a short ram. Since I'm all about weight loss, I figured I'd remove the lower pipe and give this a try. The filter was at the far right side of the engine bay behind the battery. I figured I'd get a little higher temps since some of the air would be from the engine bay. However, there's a pretty big area that exposes this part of the bay to outside air so I expected AIT's to be maybe 25-30F above ambient. I was wrong. Average AIT's were around 45-50F above ambient with it peaking at nearly 60F . It was 65F outside and my AIT's were hovering between 110-125F. My car probably thought it was 95F outside when it was a nice cool morning. The afternoon was even worse. 85F or so. AIT's? Probably the highest the car's ever seen - 135-145F. Power loss wasn't just significant, it was depressing. You'd think two or three of the cylinders were misfiring, or that I was towing a trailer. But I wanted to confirm my findings so I left it on for another day. Next day? Same thing. CAI went right back on and temps returned back to normal. Moral of the story - Short Ram is a boatload of fail.
CAI insulation - I fabricated a CAI insulator similar to Tim's in this thread: Insulating your CAI? - AcuraZine Community
I had some of the Styrofoam that he used wrapped the home depot insulation over it. I used metal tape like his. Mine didn't look as good but I feel it's probably the same as far as effectiveness . What I've noticed is that idle AIT's seem to have decreased a bit, maybe 2-3F. And that it takes longer for heatsoak to hit, where AIT's are a consistent 10-15F above ambient rather than 5-8F like in the first several minutes of driving. But after heatsoak hits, it's about the same. AIT's have decreased a negligible amount after heatsoak kicks in. It delays heatsoak a bit but in the end it's the same. Maybe 1-2F reduction after heatsoak. I'll leave it on because it's light and certainly doesn't hurt. But I wouldn't spend a ton of time or money on this.
Outlaw TB and IM spaces - I was very excited to install my outlaw spacers. However, I have noticed almost no change to AIT's
. I almost wonder if I did it wrong, though you can't really screw it up. I think that the UCM might negate the benefit of the spacers by keeping a constant flow of air hovering above the IM, therefore eliminating a lot of the heat that would otherwise heatsoak it. Before I ever installed the spacers I noticed what Tim (inaccurate) said: That the intake manifold was quite hot after driving, to the point that touching it for more than a second or two would result in a burn. But with the UCM, it was cool enough to the touch to place your hand on it. Either way, negligible reduction in AIT's.
Anyway, I hope this info is helpful to someone interested in reducing air intake temperatures. If anyone has further ideas to close my 10-15F gap, I'm all ears.
But at this point, I'm pretty happy with it.

unless you just like fucking up your car.
AND STOP RUNNING OVER THINGS and you wont get flat tires.
