New to the site

Hello everyone I own a 93 Honda Del Sol S with a heavily modified turbo 1.6L SOHC engine that I'm running a home built lean burn prechamber. This engine is something I have been working on for the last 10 years. It is purposely built for economy and racing.

To date the best fuel economy has been 74mpg at a average speed of 58mph. This was done last summer on a 600 mile trip. I have done a few other 70mpg trips also.

The next step is to see how far I can go on 10 gallons of fuel.

I used to have a '95 Del Sol S. I got 47 mpg, but that was with the 1.5L and a 5-speed. I would love to see the specs on your engine.
