RX8 Milage Update - Summer update


We are midway through the summer and the RX8 mileage continues to be about the same.  The last tank covered 247 miles using about 13.9 gallons of premium gas.

Driving was a mix of city and highway driving with most of the driving done on the surface streets near my home and work.  I am now using the entire RPM range of the RX8, redlining the rotary every trip.  The new motor feels much more powerful.  However, I still experience dips in power at 4k and 7k.  It would be nice if this could be smoothed out.

Welcome to Zero Weight Project

Thank you for taking time to check out the project. Our goal is to increase the perfomance of the stereo and car without increase the overall net weight. Also, check out links to our sponsors. We plan to have the project completed in time for the NOPI Nationals. Of course, I would love to find out what you think as well, so make sure to comment. See you around!
