111RS #3 Build: AC & Stereo Improvements

 

We are attempting to improve the lackluster AC and stereo performance on this build.  We've not attempted much in either of these categories in the past so wanted to make some progress here on this car.

We have had clients ask us to improve AC performance for years.  Next year, we plan to look at new HVAC units but this year we have too many other product developments that are consuming our resources.  So simple ideas are what we are testing here.

Adding insulation to a few key areas is one idea.  We first insulated the inside of the actual HVAC unit.  We had to rebuild it due to the rodent damage so it gave us the opportunity to add some insulation on the inside.  We brainstormed that this may be an more effective method at keeping the cold on the inside.  We have also added it to some of the ducting in the dash.

The stereo is also getting improved on this 111RS.  I have removed the stereo from my last two Elises as I have not put much thought to sound systems in these noisy cars!  Ironically I love music so a nice sound system seems like something I would have already sorted.  This car will get our first attempt at creating a better system that does not add too much weight or wiring complexity.  The high level plan is to create a subwoofer box that will take the place of the passenger foot rest.  This box will also house an amp and Bluetooth to connect a phone that will stream music.  We will use the stock speaker locations with upgraded speakers.

This car had some messy aftermarket wiring work done.  Carlos reversed it so we can create a plug and play harness adapter for our solution.  One of our good friends also has been experimenting with sound deadening ideas in his Elise.  We are using a product he recommended under the seats.  It is heavy but lets see how effective it is...

We will reinstall the 5lb foam insulator behind the seats.  This was an easy weight reductions we used to employ!  This car will have more power courtesy of the KATANA3 so we can afford to add a bit more weight.  When we are done, I think we will still be lighter than a stock Elise - but the scales will tell all!
