Some Basic CAI Questions

[ALLOY2007GT]

Thanks for all the info! I think I'm pretty much sold on the tuner option. Now I just need to decide: C&L, JLT, or Demolet. Has anyone ever got the custom paint to match your stock color on the JLT or at least seen pictures? I'm wondering how good the paint job looks and how well it matches.

JLT uses factory paint codes. it matches perfect and looks good.

C&L has the aluminum(uggly) pipe and a black plastic(hot looking).

The demolet appears to be almost equal in design as the JLT. i DK about the paint though. lightblade can tell you about that.

IMO the red filters look much better than a green or yellow or blue or whatever.

forgot to mention, I'm also planning on the Borla stinger axle backs. so, the CAI and stingers is all that I plan on for at least another year. would I need a custom tune with the stingers?

No tune for the stingers. the stock exhaust flows very well as is. the mufflers will give you about 2 hp, and are made really for the sound.

Demolet does the same, they use the ford factory paint with clearcoat, they have pics on their site.

+1 for no tune w/ stingers

wow, i'm really forgetting alot tonight

How much does it typically cost to dyno your car? I really wanted to do a before and after as well.

75 bucks for 3 pulls seems to be average.

if you want a custom tune, it will be $300+

do the before and after in the same night. do 2 pulls stock and 2 with the intake/tune. youll probably end up with 20+ hp more. gotta love it.

Yeah $75 for 3 pulls or $100 bucks an hour is the average here.

where do you go for dyno pulls?

You need to find a automotive shop, preferably mustang, that has a dynojet or meter in your area, check the phone book if your not sure of one and give them a call. Just ask if they have a dyno they will know what you are talking about.

light, we have been postwhores today, lol!

 

[bigcat]

or google dyno shops near your city.

I was thinkin the same thing

That's funny because I think the aluminum pipe is by far better looking than the cheap plastic racer one. I've had both in my hands at the same time too.

Your opinion is wrong. just kidding. I do wish they would come with different finish options like different powder coating colors or polished. that would be cool. Thats partly why i like the racer style because of the black.

It seems to me like the extra power would come from the extra quatity of air. I realize that a metal tube will soak up the heat and essentially heat the air. But, it seems like the effect of heated air would be negated by the fact that you are flowing much more air than stock. Does anyone have any experience or dyno numbers to show plastic vs metal intakes?

The heated air is not negated by the size of the intake tubing or velociy of the air, thats the whole point of a "cold air intake" to bring in cooler air into the engine, granted it also brings in more air only because of a highflow filter and maybe a bigger mas and tubing. Just look at a supercharger, compressed air moves way faster (goes into the engine quicker) than a normaly aspirated engine can suck(vacuum) the air in. But that compressed air is now very hot, thats why intercoolers work and make alot of power with forced induction. Bottom line,cooler air makes for better more efficient combustion, thus more power. And as far as heat soak between metal and plastic intakes, the metal one will trap and hold way more heat thus making the air coming into the engine hotter. Why do you think ford uses plastic composite intakes? Because they run and stay cooler and make more power. Thats why after all these years no one has made a decent aftermarket intake for the 2v.All the metal ones, even the ones that have been ported and polished so they flow better suffer from heat soak and fail to make any decent amout of hp over the cooler plastic intake. Hope this helps Having a metal "cai" may look nice to some people, but will never make more power than a plastic one that allows the air to stay cooler.

I definitely see what your saying and it all makes sense. But, if you look at any aftermarket CAI what is it that makes the air "colder"? Am I missing something here. The main difference from stock is that you get rid of the airbox and have a high flow filter. To me this equates to more air, not cold air.

It's been mentioned several times in different threads, but even the stock airbox is indeed a cold air intake. It's not a great one by performance standards, but does it's intended job very well. It does get cooler air from outside the car via the front fender, although that is VERY restrictive(I will post a pic of that restrictive air inlet). One of the reasons I chose the WMS w/ram air tray was the fact that it gets its air flow through the grill openings and up through the 3 large holes cut in the radiator cover(also a pic posted to show these). I briefly thought about getting a hood with scoops to greatly intensify the shot of air to the filter, but I care more for a cowl hood. I will get the Cervini grill to replace the stock one(that will let in a bunch more air).

You are right for the most part, the main reason for more power in a cai is the "less restricted air flow", but that doesn't change the fact that hotter air will rob power, and metal parts in the engine bay soak up heat and make the tempature under the hood(where the intake is) hotter. And what a cai does is make the intake air cooler by being able to pull in the air at a faster velocity. Just like the fatser the wind is blowing the colder it feels. So the faster the engine can pull in that cooler air, the less time it has to come in contact with hot metal parts aka the intake tubing. Oh and the stock air box is like an oven that holds in heat and slows the air down.

BTW nice setup kooldawg!
