What is the trumpet horn for on the front of the airbox? If I remove it can I get greater airflow? Is there a reason that it is there? Any help would be much appreciated. Thanks

Ken,
I've got a 95 and put in a K&N and figured that removing the horn would allow more air flow, all I noticed was a change in engine noise(little more like a v8) but haven't had any problems in 20K miles. My 2 cents.

Don't alter the air horn for any reason.

Jim Allen tried various configurations and they dyno'ed the results. All resulted in some loss of power, albeit small. It appears that Rover did quite a bit of research on the dynamics of air flow and apparently got it right.

In the words of Gomer Pyle, "Surprise, surprise..."

thanks Joe, thats reason enough for me to take it off. I just dont want to open a can of worms, but if you had no problems hopefully I wont either. Ken

You can't do that? Leave us on the edge of our seats! What happened?

What if you have a K & N filter/HIGH FLOW exhaust system and the engine can actually breathe?? How does the horn come off?? Do I have to cut it or does it pull straight off?

Don't take it off. One of its purposes is to prevent/channel the egress of water from your intake. Might not be much of a problem out west, but here on the east coast, you are asking for real trouble. If you are really dead set on doing this, build a snorkel.

If you have the GEMS system, there is nothing that you can do to significanly affect the horsepower of the stock vehicle. Chaning the intake and exhaust will not make any significant amount of difference because the Air Flow Sensors will just adjust out any increase. It might feel better, but it is mostly a seat of the pants feeling because you made it louder.

However, on a pre-GEMS system, the improvements could be significant. The first things the old time hot-rodders (me included to a certain degree) used to do let the engine breath better with better air inflow and better exhaust. That was usually followed by replacing the carb or re-jetting it.

The newer stuff is much more complicated. I think the only way to get significanly more horsepower is to re-chip the engine to take advantage of better air and exhaust systems.

LoL,
Mike

I am no expert, however, the horn appears to work as a convergent nozzle. its purpose is to reduce airbox noise making the vehicle compliant to the over regulated federal stds. yes pull the damn thing out, you will notice that there is a big difference between the I.D. of the horn and the hole that it is mounted in. does it increase air flow. well without testing, commons sense would dictate better air equates better performance. in theory! as mike has said there is more involved in an attempt to increase performance, and that is true with all aspects of mechanical operation, if you change one part it is necessary to change or modify all related parts. having said that the horn is a waste of plastic and gets in the way of the good place to put the second battery. so in this man's view ripped it off, and chunk it in the round file. good rovering!!!!!! mike w
