Ok, bought a brute force intake on ebay it was used but in great shape. Have no instructions. I have the old intake off disconnected 2 sensors, and pulled 3 hoses out of the old intake. Question number one, is how the hell do you get the factory intake box bottom off? Question number 2 looks like on the brute force intake there is only room for 2 sensors and 2 hoses. The very small hose not sure what it is but assuming it is the boost vacuum hose. Anyway can anyone help me out asap, i got the truck tore down and need to get it back up and going.

Thanks,

 

Try going to the company web site and see if you can pull up a picture or maby the instruction sheet. Might help as more and more companies,are doing that not just in the automotive world. Artie

 

Well finally got it all put in. Website didn't do me anygood. I got everything installed but I can't get the iat sensor to stay in. There is a rubber grommet that it goes into but it just comes back out. I put some clear silicone on it and maybe that will hold it in. Man this thing sucks the air like crazy. You can hear it just idleing. Gonna see how it does on the street!

 

Well on the street it does pretty good. Is it normal to pick up more boost with a aftermarket intake? I'm running now at wot around 9.5 on the boost gauge. And man oh man is it loud, is it normally louder? The whine is a whole lot louder than factory. Anyone know how much hp gain i'm getting running 1.5 more pounds of boost?

 

 

Yes, it is normal for the gauge to indicate more boost.


Umm, yes. You replaced an enclosed box with an open filter.

About zero, because the boost gains are illusory.

The increase in boost is some sort of measurement anomaly. If we were picking up a pound or two or real boost from an air cleaner swap, then we would be picking up about 15 rwHP per pound of boost. Unlike a pulley swap, an air filter boost gain would be pure extra boost without extra heat. But gains from air filters are in the -5 to + 5 range on a stock or near-stock engine.

 

I'll keep this simple:

if you are making more power it's not very much:


"boost" is a measure of backpressure (air not going through the engine)
Backpressure is basically a measure of resistance.

Being that you have few mods, the engine can only flow so much air, after so many mods you reach a point of diminishing returns. That is why the basic, tune, pulley work so great, after that, the bolt on gains are minimal.

So just because the "boost" gauge shows more boost, doesn't mean more air is flowing through the engine.

Remember ALL gas engines are simply an air pump. The more air you put through it, the more power you make.

EXAMPLE:
Too much boost will hurt you as the stock valve springs will allow leakage at higher RPM's... this has been shown over and over on dyno charts and discussed at length by Charles Warner from magnum powers.

 

Gotcha!! Thanks for the input, it does sound good though!
