TRD CAI and Exhaust HP Gains

With more of them we could avoid so many nasty thing's.

FRS Matt you are such an open minded smart ass.

I am an open minded smartass. I'm also not a TRD money wasting dumbass either.

I like the idea of TRD stuff, but I have yet to see any dyno stuff. Sucks too because I love the exhaust sound, but if there is no gain at all, or even a torque loss *gasp*, I wanna stay away from it. That intake looks like a cool idea, but gains are probably minimal. Aesthetically it is cool though. I went for the K&N drop in and the Perrin Silicone Hose.

I have scoured this forum for dyno stuff on TRD, and just cant find it. Hopefully something will show up soon so we can all know if it is worth it.

If you seriously didn't understand what I was saying with that post, there's no sense in trying to explain it to you.

If you DID understand and were merely being a smartass over comma placement in a sentence... I have nothing to say to you.

Umm yeah.... ok?

I'll stick to my stock box with the stock filter.

Anybody here get this TRD CAI system yet? I know a few on another thread did, but nobody has done a dyno yet.

If I end up with it, I'll dyno it. I expect someone will get to it before me though.

Interesting, different strokes for different folks! Where you see a big eyesore, I see the CAI as cleaning up the looks, the aesthetics of the engine bay, while getting rid of the sound tube. Mine will be installed by weeks end and while I'm not anticipating huge HP gains, I'm hoping to be pleased with the looks and that it won't be terribly loud.

When it comes to under good long as its clean I don't care. Realize some do, to me if this was a big bay, big v8 and old school I'd care. But it's not its a 4cylinder with very little any common person can wrench on really. Sure a little more room would be nice I agree but seems so many CAI systems are doing nothing but looks anyhow?

please correct me if I'm wrong ! i don't mind getting educated about this too !

You are sorta kinda correct. Higher octane fuel, all else being equal, will not give you more HP/torque and could actually cause you to lose power if your car is not tuned or set up to use the higher octane fuel effectively.

First thing to understand is that higher octane gasoline generally has slightly lower specific energy (Btu/gal) than does lower octane gasoline. Please note I said slightly lower. The difference is not much.

Second thing to understand is how your car can benefit from higher octane fuel. If your car is originally designed to use 87 octane fuel and the ignition advance (timing) is not limited by the use of 87 octane, higher octane does nothing except lighten your wallet. If you raise the cylinder pressures through FI, higher compression pistons, or use a more aggressive ignition timing, you may need to run higher octane. The additional power you get is due to the FI, higher compression pistons, and/or more aggressive tune. The higher octane fuel is needed to keep detonation at bay (engine knock) while employing FI, higher compression pistons, and/or more aggressive tunes.

Higher octane, that I know of, does not burn "cooler" than lower octane fuel. Higher octane fuel actually does burn "slower" than does lower octane fuel. This is why higher octane is used to prevent detonation with FI and aggressive tunes. The detonation (knocking) that you hear with lower octane fuel is actually the fuel burning too quickly, more like an explosion versus a controlled but quick burn inside the cylinder. Those little explosions in the cylinder from running fuel too low in octane in your high compression engine are what cause the damage to the tops of the pistons.

Hope that helps a little.
