I put a new wolf whistle on my intake manifold and it does not work. The wiper works well. The air just rushes through it with no whistle. What could be the problem?
Not sure about the newer ones but the older ones have a spinning disk at the bottom of the trumpet. If yours has one check to be sure its free. Also check to be sure that the adapter to the manifold has a large enough hole. They like lots of vacuum!
Good luck!

It would be sucking under hood air, which is usually quite hot. It would also be mixed with the much greater volume of carb air before hitting the valves. I say no danger.
I had a wolf whistle on my 55 Chevy in high school, and never had a problem.
Once in a while I'd have to spray some light oil on the whistle spinner to make it blow.
Also make sure the whistle spinner isn't installed backwards. The spinning disc faces AWAY from the open end of the trumpet.
had numerous 'wolf' whistles. found MANY that were actually made wrong. they were the brass screw in motor type (the part that does the whistle is called the motor). many of mine had the screwdriver slot ON THE WRONG END. replacement motors are available from Speedway.
yes, I have encountered other problems with them too. most notably is the cast ones always crack at the large threaded fitting creating a vacuum leak and making them inoperable. I make up new ones with a thicker base out of brass.
