so is it worth doing. if i gain nothing?

You really don't gain much if anything with a CAI other than quicker throttle response and sound. With the URD MAF Cal it helps a lot, but still it's no super charger.

Intake, headers, exhaust are worth the money if you ask me, but don't expect a 50hp increase.

thanks for the info.

im really looking into a TRD INtake DTLT headers URD Y pipe and TRD cat back exhaust and then of course URD Maf..

I just need a place to tune it for me in utah.


and also i think with the Y pipe and DTLT headers my check engine light will be on always so idk if i want that. or not?

with an intake, headers, urd y pipe and tuning (x1) I put down 250 whp and 300 ft lbs. That is effectively the same power netted with just a trd supercharger.

Out of the two intakes listed I run the AFE intake, but would love to run a URD intake. If you want to go mudding and driver though rivers get the TRD/AFE. If you do light off roading or don't get the URD.

Wow. That's pretty impressive, considering you probably have a fraction of the $$ invested that a SC would cost.

When you mention "tuning" - are you referring to a MAF re calibration, or something like a Unichip?

(I like your "recipe" and might want to copy it!)

I've been looking at the N/A gains thread and am surprised how much people are netting from gains. The general opinion on here is that "it is proven that none of the bolt on mods gain you any performance" Well looking at all the dynos in the NA performance threads means that either, you need a few of them instead of just one to gain anything, or you just need a tuner, like a Maf Cal, to get the gain out of those mods.

http://www.tacomaworld.com/forum/per...os-w-mods.html

One thing to note is that these guys may get peak gains that are comparable to just the TRD S/C, but I'm sure over the entire power band that the TRD S/C has more power, ie both may have 250hp at 5000rpm but at say 3000 rpm the S/C will have like 240hp and the N/A will have like 200hp. (I just made up those numbers to show my point)

And, don't forget you lose about 3% of your HP for every 1000ft above sea level you go. A supercharger keeps that loss to a minimum.

Anymore, the manufacturers are making some pretty efficient intake and exhaust systems so you get very little HP/Tq increase with CAI, Headers, and exhaust systems. There is no way a few little add on parts are going to compare to a properly installed and tuned supercharger.

Actually not necessarily... A supercharger experiences the same losses as a N/A engine at altitude. It compresses the air based on a ratio of how fast the rotors are spinning and the air coming in. Of course a supercharged engine will do better than a N/A engine at altitude most likely by virtue of just more power though. A turbo does much better of mitigating the effects of altitude as it has a set psi to reach. However, it has to spin faster to reach the same psi at higher altitude so some of the power is lost due to heat...

As for the second part the I/H/E don't do much on a naturally aspirated engine without a proper tune, but they work wonders with the higher compression that comes with a boosted application.

Trd, you have to watch the URD like a hawk if you go offroading, going to carwash, going to dealer, if it is raining, dusty, etc. Even with the splash shield, I would still worry.

I researched the intakes before i bought one, it was a toss up between the URD and the volant with scoop. I went with the volant + scoop, closed box unit and sucks in from the fender and the open scoop replaces the rad shroud. Truck has more pedal response and sounds way better, i don't care what those "anti CAI" people say

edit: i had a flowmaster 50 series dual exhaust installed before the CAI and the CAI made it sound way better
