Engine Super Charger & CAI

I'm only talking about with forced induction..... I only think it helps with the amount of airflow.....which (like stated 100 times) an aftermarket drop in filter would do. Think about it....the air has to go through the compressor before it gets to the engine.....the smoothness and the temp of the air that the CAI created will be worthless there.

Well, if you check my sig you would notice "supercharged" meaning that i'm talking about the CAI with FI. And I'm TELLING you that there is a huge difference... being a s/c owner.

ok and I have a turbo 03.....what's your point? Doesn't change the fact that a CAI is pointless on a F/I car. Unless you already had one when you bought the S/C that's the only way I could justify it. Did any of you S/C guys dyno the car with a CAI and with a High flow drop in filter?

My dyno was with the TRD S/C'er and cat back exhaust w/ K&n drop in filter then TRD S/C'er with same mods and unichip gained a little over 10 hp and then w/ the CAI i gained another 13 hp. So yes that was on top of the drop in filter. And not only looks but the sound Anyone that has heard mine or Larry's videos or a S/ced rolla in person with a CAI you know what I am talking about.

I really don't think a CAI would add 13hp to a S/C.

I think this is a topic we should agree to disagree on.

Ok frankly at this point I dont care what you think. If it has been dyno proven on 3 different cars why would you disagree. I want people that have the TRD S/C'er know there are ways to increase the power and performance and the CAI is one of the best. So how many people agree with me on this?

I agree it makes a difference. I don't really care that I can't explain it, but hey. I'm not paid on my technical ability on cars. I agree to disagree. I've had the stock box and the CAI on my rolla when it wasn't sc'd. there is a difference. I've had the stock airbox, the TRD drop in filter, and the CAI on the sc (not at once, I'm not a complete knot head), there is a difference. Did I have it dyno'ed everytime? No. Why? I didn't want my money to go to the dyno, instead I put it into other parts for my car.

All I can say for the turbo, I have no idea what it could do for you...I have the sc and it matters.

you will probably get about 2-3 hp gain with an intake on a N/A setup, but with forced indection everything is heightened. 10hp is definately achievable.

Yeah this topic is getting kind of old now......That's why I said let's agree to disagree. With a CAI or not, the TRD supercharger is bad ass....I think that's something we all can agree on.

Trd Cai

According to TRD, when you install the CAI from them, the increase is 8hp/7tq at the flywheel, on a 1zz-fe natural. (11hp/9tq on a 2zz-fe)
AND.....because it is an official Toyota part, it does NOT affect your warranty.
This part was thoroughly tested to see if it would affect either the engine longevity, or the emissions and control systems downstream from it.
In both cases, TRD found that it's CAI had no adverse effect on either.

So if you are running rich, then maybe your O2 sensor should be sending that info to the ECM so that it can correct the situation, by leaning out the mixture.

If you burned out a CAT, I'd say you should check to see if the O2 sensor was fried first, or you will be back soon for another replacement CAT.
