Just a few questions about ram air before I go setting mine up.

I have the TPI motor with the 2 square filters on the sides of the hood latch. I plan on cutting the bottom of the baffles out under the filters and putting in the duct work from the fog light holes up to the filters.

My question is, will I have have to worry about water getting through the filters. The reason I ask is because I heard that the K&N filters wont stop water from getting through like a regular filter would. And being that with this setup it would be an open path from the front of the car straight up to the filters that could cause a problem.

So is this a load of crap or am I not going to be able to drive my car when its wet out???

 

An air filter won't stop water, whether is a K&N or a plain old paper filter. I don't think you'd have problems with it though. There are plenty of other guys out there with the same setup and I haven't heard them say anything about having problems.

 

Water, like air, does not like to turn corners nor does it react favorably when confronted by an obstruction such as a sharp bend in a hose or a baffle. This will prevent most of the water to travel all the way into your induction system. Besides a little water can clean the chambers out for ya. Water is made during the combustion process anyway. H2O, CO2 are by products of complete combustion. Now Incomplete combustion yeilds those two and CO, NO(X) --x stands for any number-being they are oxides, SO(X) and some unburned Hydrocarbons (fuel).

So basically...........It will be alright.

Also..

A=CID * RPM/ 20,839

A= effective filtering area
CID= cubic inch displacement
RPM= revolutions per minute at your maximum power

so, for example, a 350 CID Chevy engine with a horsepower peak at 5,500 rpm

A=350 * 5500/ 20839 = 92.4 inches

Use the formula above to compute the minimum size filter required for your particular application. The usable portion of the filter is called the EFFECTIVE FILTERING AREA which is determined by multiplying the diameter of the filter times Pi (3.1416) times the height of the air filter in inches, then subtracting .75-inch. We subtract .75-inch (an estimate) to compensate for the rubber seals on each end of the element and the filter material near them since very little air flows through this area.
