Default Supercharger and CAI - is it possible?

Hey all...I'm looking to make my supercharged tC faster. Is it possible to add a CAI to a supercharged engine? If not, what are some other ideas??

Is it really useful, other than being a filter? I'm not being smart-@$$ed, I'm really asking.

I think it will help a little since going through the supercharger makes the air ultra hot. I don't think you'll feel it much though ... but you get a cool sound, haha.

Haha...well I've already got that "cool sound" thanx to the supercharger!

Ok...so, if I CAN add a CAI, where do I get one that'll fit to the supercharger?? the blower obviously draws from the filter, and with that supercharger under the hood, there isn't much room for a standard sized CAI.

Has anyone found a solution to my problem?? i.e....you have a supercharger AND a CAI?

THanks for the help...

Is it safe to put a CAI on the S/C? I read somewhere that the A/F ration leans out with CAI.

The CAI will have to be custom made.

You can make your own CAI from Spectre's Power-adderr kit, they have bent pieces straight pieces (or use a flexible tube) and even a piece for the MAF. You can buy the pieces online or pick them up at pepboys/autozone/checker/advantage(?)/ whatever your local car shop is called.
However, I have also heard that the CAI on a S/C leads to too lean of a mixture and based on that I would not recommend that you pursue this idea, as it may lead to sputtering, stalling and maybe throw a CEL.

So have fun and tell us what happens if you end up doing this (don't take my help with the CAI as an indicator that this is a good idea I don't think it is unless you have the means to correct the problems that might arise).

Spectre is good for N/A applications. It won't hold boost though - you don't want to go from the SC to the Throttle body with spectre piping.

If you do a search, you'll see that CAI's on SC's lean out on the A/F ratio using the TRD ECU Map. I'd only do it with fuel management. Without it, you'd probably do damage to your engine.

I wouldn't boost a car without fuel management S/C-Turbo, etc.. Too easy to enter a lean condition.. + when you have fuel management at least you have something to fight Scion's combative 64bit ECU

Ok...

So sounds like I'll be scratching the SC/CAI idea...I definitely want to stay away from leaning out the A/F mixture. (I'll be sending back the Injen CAI I ordered last week...)

What are some good alternatives to boosting HP?

05-RS1...

was looking at your profile...you got some nice upgrades done performance-wise (i.e. headers and such). would you reccomend them to others, or...

Headers and exhaust should help a little.

Get a wideband 02 and then try upgrades. The TRD supercharger is still rather new and parts are still being tried and tested. So go get a wideband 02 and pave some trails for us.

umm recommend what part exactly? and depends more one what ur lookin for..

header, if u got money and want to get the most out of them, then the MMW 4-2-1 should be the way to go..i bought the AW header couple months before word about the MMW header even came out. but im pretty satisfied with the 4-1 header. i took the header off when i went to get the s/c warrantied and there is a noticeable difference when header on and header off with the s/c. while the header was off, i decided to get it coated by swayntech, and the temperature reduction is amazing! CAI before s/c i didnt feel much of a difference but it does improve performance (jus not enough for u to feel it lol). umm draxas s-pipe is a great piece. i wanted a quiet exhaust so i got the sp2. bought the 2.5" midpipe from kytc, it has 2 resonators on it to quiet the exhaust with the header on. btw, i wouldnt recommend any header + trd exhaust combo. its jus grossly loud..might be some ppl's cup of tea but not mine.

hope this helps!

Hey yeah, thanks...

I DO have the TRD exhaust...maybe a mistake if I'm considering the upgraded header? I think I'm willing to experiment with the "grossly loud" sound the 4-2-1 header-to-TRD exhaust will provide...but if you like a modest exhaust sound as much as I do...maybe I shouldn't do it.

Still looking for the right product I guess.
