Hey guys-
I emailed the guys over at K&N about their intke take system for our Magnums. I had a few questions that I wanted answers to and I figured that you guys might benift form seeing their reply. I'd like to add that they got back to me in just a couple of hours. (I was impressed)
my email:
I have been waiting for you at K&N to come out with an intke system and now that you have I am very excited. My questions comes from two facts. One, that their is now way on your system to prevent the intake from sucking up hot air from the engine, is this a concern you also have? What info do you have in this area? My second concern is that their is no mass air flow on the car. I'm not sure how their can be a horsepower gain by getting the intake to suck up more air if thier is no way for the engine to know that it is getting more air. Thank you for your time and keep on make the great products you guys make.

I am glad to hear you are excited about our new Typhoon intake system
for the Dodge Magnum Hemi. I'd like to give you some answers to the
questions you asked about this intake system.
The filter is protected from engine heat by a heat shield assembly (see
picture below). This is not an isolated, sealed box, but rather a
shield to keep the filter protected from the heat radiated by the
exhaust manifolds, engine block, etc. While the vehicle is in motion
(above speeds of 15 mph) the airflow coming through the grille is
sufficient enough to push this heated air back towards the firewall, and
out under the vehicle.
A mass airflow sensor is not the only way for a vehicle's on-board
diagnostics computer to calculate the volume of air coming through the
intake system. The hemi engines used by Chrysler from 2003-present do
not use mass airflow sensors, but rather a combination of other sensors,
to achieve the same result. These sensors are the throttle position
sensor (TPS), the manifold absolute pressure sensor (MAP), and intake
air temperature sensor (IAT). Honda also uses this process on some of
their vehicles. The end result is the same-the ECM is able to calculate
the volume of air being ingested by the engine, only the method of
calculation is different. So, a performance increase is achievable,
even though the vehicle doesn't use a mass airflow sensor. The dyno
test results haven't been published for this intake system yet, but in
our preliminary testing we achieved a 12.5 HP increase over the stock
intake system.
I hope that your questions and concerns were answered to your
satisfaction. If you have any other questions regarding any of our
products, feel free to reply back, and I'll be glad to help you out.
