OK guys, I'm just about ready to go have 04 Lightning Dyno tuned. I have Bassanni cat back,FTVB, BBP,oil seperator and currently a K&N drop in filter with modified air box. I HATE to beat a dead horse, but is my filter set up OK or do I need to install the CAI?? I will be installing a #4 pulley just before I hit the dyno. I have a LFP (Lightning force performance) CAI still in the box thats never been installed. After I ordered it I started reading more about the hot air that a set up like this would utilizing. That scared me, so I never installed it. I saw where I could order the Fast Air kit from PSP and possibly utilize the filter system that I have from LFP? But, I've also been told that with a system like the fast air or the kit from JLP that a turbulance effect is created right at the MAF meter and that causes problem at a steady state cruise with your AF ratio? Been told that these kits were meant for drag racing type driving and that everyday driving was not considerd when they designed these kits. So, I'm totally confused as to what to do. I feel like I'll need more air than my current K&N set up is able to supply, but dont want any "regular" driving issues. I've considered the Airaid set up because it utilizes the 12" filter but doesnt have the cool air tube and scoop that could cause this "supposed" problem. What should I do?? Also, I plan to send my SC to Apton in the future for porting. I know I'll need some air then. I've attached a link to a picture of the set up that I currently have from LFP. Thanks in advance.

Our PSP FASTair induction system is the best cold air kit you can put on your truck. There are no negative effects from using it. And you can use it with your LFP filter kit, just order the optional bracket along with it (listed on the site with the FASTair).

Hope this helps.

 

No Driving Issues Here!...Where did you here this? JL

 

You now have both of the popular TRUE "cold air kits" in front of you.

An open (non-enclosed) filter is a HOT air kit -- much hotter than the stock box.

IMHO, you would be crazy not to get one of the above boxes.

 

Heard it from me Johnny. Read this

And no, I wasn't talking about yours or PSP kits. I was comparing the Swanson or any other open element filter under the hood, not the enclosed setups. He has a LFP setup similar to the Swanson.

jster171,

I can tell you I have a JLP cai w/shaker hood (functionable ram air) 6# lower ect, w/ Sal's tune. I drive it in all temp. conditions in the northeast. Never a problem w/ MAF readings (or AFR's). I know because I have driven it w/ my scanner and exh. gas analyzer hooked up for MANY miles. Just my 2 cents.....

hope this helps!............... Jon

 

jster171,
If you're installing a 4# lower pulley, you'll definitely need some kind of conical filter. Whether or not that conical filter includes some kind of CAI is up to you, but recommended. The stock air box with a K&N panel filter simply will not flow enough air for a truck with a 4# lower.

Also, you didn't mention if you are going to get a chip or a diagnostic port tuner (ex. Predator). If you're doing the 4#, you'll need this as well to guard against detonation and KABOOOOOOM!

 

Yes, I mentioned that I would be getting the truck dyno tuned in the near future. Again, I have the LFP kit still new in the box. If I could use it and just buy the box and air scoop from JLP or PSP, that'd be great. That way I could utilize the $189 system that I already have. I heard the rumor of the steady state cruise from a tuner in Panama city beach florida. I called them inquiring about there dyno tuning and was asking about the CAI kits. He said they didnt like the scoop kits because of the turbulance problems and said it'd be only scooping in hot air from the hot summer pavement. But like Tim Skelton said, science dont lie, and acual intake temp is one of my biggest concerns. I think I'll give JLP and PSP a call to see if both kits can be used with my LFP air filter and MAF bracket.

 

I don't quite understand why they told you they don't like scoop set ups because they draw in hot air from the summer pavement. Granted, the air is warm, but it definitely is not as hot as the air immediately around the engine. And, when you get going, the air will cool down just from driving.

 

jlp is the way to go.

 

Exactly. And I'd like to see some real data on the heat 12" from the pavement and the heat 36" from the pavement.

I think that people are confusing radiant heat with ambient heat. Yes, there is more radiant heat nearer the pavement, but unless the air is absolutely still, I cannot imagine any significant difference in actual intake air temp between a scoop and the fenderwell opening.

 

OK guys, after compiling all the data I received, I just ordered the JLP CAI set up with the air scoop. I went ahead and paid extra for the lid. I hope I like it!!
