Anyone ever built a cooler blower?

I was down at the track a few days ago, and noticed that after track sessions, everyone else opens their hoods (or trunks for 911s) after a track run to cool down their engines. Obviously, this is not practical to do for the Boxster.

If you ever watch F1, when they pull the car into the garages, they will put little battery-powered blowers over all the air inlets to cool them. I was thinking about building a similar thing for the Boxster. I assume you would rig it up to blow into the passenger-side inlet, as that goes directly into the engine compartment. I even tried it yesterday after a "spirited run", just using a leaf blower to blow into the passenger-side inlet, and it seemed to lower the temperature pretty well.

Has anyone ever tried anything like this? I'm going to try to find a small electric blower that will work.

The car already has one controlled by a thermostatic switch mounted to the intake manifold. Just splice a switch into the circuit if you want to manually run it. You can also run it manually through the PST2.

Its only the passenger side if your left hand drive.

And why would you want to do this?

anyway a small generator and a leaf blower should do the trick - theres nowt so queer as folk :D

On my Talon when I drag race it, I took an old fan from the radiator that was replaced with slim fans and built a stand for it. I wired it up with a set of alligator clips and a switch. It would sit right on the top of the valve cover/intake manifold and clip it onto the battery then hold onto it while I flipped the switch. The motor had torque so you had to hold onto it when turning it on and off, once it was running it would stay in place.

My valve cover after 5-6 back to back 1/4 mile passes down the track with 400hp would be on fire, my intake manifold is sheet aluminum. Within 10 minutes of that fan being on it everything would be cool to the touch. I also wired the radiator fans to stay on as well. It would cool so much that when I started the car after about 20 minutes (10 mins with the fans on 10 with them off) the temp gauge would be below the normal operating level of half.

Now on a boxster it's sooo much work to get to the engine. However for racing I would wire the fans up so you could run them constant even with the car off, should be pretty easy to do. Also a fan on a stand to blow into the non-intake inlet on the passenger side would probably help a lot too...

As said above, id probably go with wiring the stock fan up to a switch so you can turn it on when you like, its a great little heater for your garage on them cold days

Got fans....
