Recent Consumer Reports tests found some cars got 40 to 50 percent less fuel economy in city driving than the Environmental Protection Agency estimates. The EPA said it plans to come up with new estimates later this year. The adjusted figures will take into account the stop-and-go driving we do on today’s congested roads, as well as the drain caused by accessories we love. But Dianne Whitacre at The Charlotte Observer points out the “only way to find out your car’s gas mileage is to keep your own records.” Alternatively, many vehicles offer built-in fuel economy tracking systems.

People need to wake up to this groovy design developed by a bare footed mechanic in India goes the story in Popsci Sept 2004 issue, Future of the car. More can be accessed by doing a google search for this visionary. Somender Singh is his name. He even has a website http://www.somender-singh.com
Open Source Energy Network have a detailed article on his ‘Design to improve turbulence in combustion chambers ‘ & how to attempt hacking your head. I think the EPA needs to wake up to simple solutions before gas runs out.

There are more than just stories at his site.
So far about six people have taken the instructions on his site to their mechanic and had the heads redone.
Only positive comments. Like… idle speed down to 600 from 1100, engine temp 20 deg lower, smooth accelleration in second gear from a dead stop (89 Celica) etc.
Each engine tested from snowmobile to lawnmower, diesel, gas, racing engine and daily driver post these same results.
People would have to be idiots not to see the advantages of such a simple modification.
Somebody has got to see the benefits of this. I’d spring for testing if I could, but rising interest rates have me scared to do anything right now.
Good luck Somender!
