V10 CAI worth it?

[joepizuro]

I don't care about the sound of my truck. Just performance. Does anyone feel a difference with a cai? I been thinking or just doing a K&N drop in..

Also these posts give v10 users results when they google.

Not on my vehicle. But my buddy put a cai in his ranger. Average intake temp dropped about 25*. However the difference in power was barely noticeable, you might get slightly better results with a larger displacement engine, more than twice his 3L. Personally I would put a washable K&N in there, Our fender intakes are pretty good as it is at not pulling hot engine air. I would assume its the same on the v10's as it is the 5.2L and 5.9L where your intake temps get up to stupid high levels while idling 100+. That is more due to the IAT sensor placement than anything else, and the poor sealing between the fender and the filter via that poor friction fit plastic tube.

Sealed mine with a rubber O-ring I bought at a hardware store and dropped aprox 7* at idle.

Air intake is different than the V8s. Inlet is by the battery I do believe. I would just get a cotton gauze drop-in, Spectre's are cheap. There are other worthwhile mods for the same money. Unless you make your own.

So a 25 degree difference and can't tell a difference? I can't justify the 300

+1 to K&N drop-in.

Cold air intakes were the stuff back in my Honda days. Of course, fart cans and stickers were held to about the same level and we all know what those did for power, LOL. At best, a CAI yielded an extra 2-3 horsepower at peak, which on those engines was north of 5,000 RPM.

Magnums in stock form don't like to rev much north of that. So, at around 3,000 RPM, you'd probably gain about the same power.

The V10 would probably pick up a couple more, so I'd estimate that you'd gain 5 horsepower at around 3,000 RPM.

Running like a daily-driver, I very highly doubt you'd notice much difference in power. You will probably have noticeably improved throttle response, however not much more than if you simply went with a K&N drop-in.

Couple hundred bucks for a bit more throttle response is a bit much I think. Me personally, I swapped on an open-element air cleaner which allows more direct airflow into the manifold, though this if offset by the fact that it is drawing in hot air from the engine bay rather than the cooler "fender feed" air. My throttle response did improve, but nothing noticeable in actual power increase.

Yeret said it pretty well, I myself went with a K&N washable filter because my truck runs in incredibly dirty environments on a regular basis (I patrol an industrial complex usually once a week) My old filters would get clogged every month or so, at least to the point where they were nasty. I was my K&N Bi monthly, and boy does that thing need it. Looks like you washed the black off someone when i'm done. The cost of the filter was paid for after I washed it once. Plus, it bumped up the response off the start. Not by much, but enough to bring a smile out of me, I improved it.

That plus sealing the plastic tube that runs to my fender and cleaning all the dirt out of the fender area I noticed a tiny jump in response and my intake ran about *5 cooler at idle. Which was nice seeing as it was 130+ before.

Drop in will be worth it as my truck gets dust and dirt from farm and race track(horses). Also going to seal it up. How about moving IAT sensor

Its integrated into the throttle body on the v8's I think. However moving it is probably a bad idea that will kill your fuel economy by tricking the PCM into thinking the air is cooler than it really is and adding more fuel than is really needed.

Exactly what it does. Richens your a/f ratio a tad. But then again 7mpg in a v10 isn't much different than 8-9mpg lol.

It's not in the tb is in one of the intake runners on the kegger. For the v10 I'm not sure where its at

 

[joepizuro]

No need for me to mod the a/f ratio like that. Can just change the VE map on the tuner
