Thanks titan, good info and links.

The noise...it's only when you're really stepping on it though...wouldn't hinder a conversation in the truck at all though, right?

 

It depends. On some trucks you can get drone at certain RPMs.

In some cases it's so annoying owners have used custom tunes (adjust valve timing) to reduce the drone.

 

Dang...ok

I apologize if this seems like a dumb question so don't cut my head of yet.
Do you see that problem more in certain models than just in general?

 

under normal driving my truck is not loud.
When you get on the long pedal the intake is most notable at 1,800 to 2,500 then it fades and exhaust come in midly from there to about 3,500 then it kinds looses its sound too.

Normal starts should not be too bad though, and even mild is not all that bad.

Its never been so bad that I could not talk over it.

 

Drone all depends on the person, truck and intake as well as the outside temp.

i personally think it sounds good.

however each truck/intake combo is going to be slightly different, and I have noticed that when its cooler out side, say less than 75 (72 seems to be a sweet spot for my truck) its louder but the hotter it is out side the less noise it makes.

its nothing I would call even remotely annoying.

 

Quite a few Gryphon owners thought it was annoying.

I don't really see a Grphyon in my near future, to be honest.

So I shouldn't have that problem with a regular CAI, right?

 

Not right. The CAIs have no silencers on them and you are going to hear the air being pulled through. It can also cause a vibration in the components that sounds like a drone when you accelerate. Bill has been able to reduce this at times, through proper tuning of the Gryphon. You are going to have more air noise, just a question of how much. Some peole find it annoying, some find it "music", much like people view exhaust noise differently.

 

The Gryphon doesn't cause the drone.

The Gryphon can be used to reduce the drone caused by certain intakes on certain trucks.

 

If you are worried about price and drone, go with the gotts mod. Only costs about $10-$20 and does not drone because it uses the larger parts of the stock intake. I even did some testing using the datalog feature on my gryphon and found that on my truck ('08 4.6L) I got a little bit over 5% more air at WOT(From about 190 grams per second to about 200 g/s). If the amount of air and the amount of power from the engine have a direct relationship then that would translate to about 10 extra horsepower(at WOT), pretty much the same as what a K&N intake is supposed to get on my truck. But I mainly compared the % gain. I had 5% gain in air which could possibly make 5% more power which is very close to K&N's 3.98% increase (9.88 extra hp out of the truck's rated 248) I also compared the estimated fuel efficiency of the gotts mod vs stock. I found I could get UP TO (DOES NOT mean ALL the time) 20% better (3-4 mpg) increase. I also got the numbers based on HUGE amounts of information. I had over 11,000 readings for JUST the gotts mod and over 20,000 readings for the stock setup. I also used K&N as a comparison because that was the filter I'm running (and loving). If I had a S&B or Airaid I would have compared against them.

 

yeah, its just personal taste, I find it bad azz and never had a problem.

Took a one way 2 1/2 hour ride in my truck to a eye specialist, never had any problem with too much noise at all.

Luckily me and the truck came back fine, but I am at medium risk for glaucoma and that sucks.

 

To the OP....

If this is going to be your only mod, put your cash towards a tuner and do the Gotts mod instead.

I went with an intake mainly because I think the stock set up is fugly! But if you must....go with a model that will not raise IAT like many of them do.

 

If you replace you stock filter with a high flow i would recomend airaid over k&n. i had the k&n before but had problems with the gaskets falling off and not sealing. airaids filter has no gasket, per say... the filter base is a very think piece of rubber compound which seals VERY WELL and eliminates the gaskets... i have gotts mod, airaid filter and will be purchasing the airaid intake tube to connect to the stock air box, this keeps IAT low but flows 400 cfm more than the stock tube. that should help extra airflow that gotts mod gives you. cheap way would be cut out the silencer tube from the factory tube but ill be improving performance and looks together by replacing it. i love my settup and would not buy a WARM air intake ever.
