I know this is completely counter-racing, but if you think about it, those who modify cars for more hp are the only folks with any experience modifying modern automobiles. We can reprogram computers; reshape combustion chambers, ports, runners. We change cam profiles/timing, change compression ratios. We modify suspensions, take engines from one car and fit it into another. All of these things that seem common to us as racers/modders are completely out of the intellectual grasp of 90% of the people who own cars.

I think it would be interesting to see what kind of mods could be made available to the public to better gas mileage on everyday cars.
Here’s a few of my ideas, discuss;

advanced timing, higher compression + water/meth injection is supposed make an engine more efficient right? How about trying that on an economy application.


Swap a 92 cx- or vx honda engine (40 mpg in a hatch) into a crx and pass damn near EVERY gas station.

VW tdi engines are great diesel sippers- 50 mpg or so. Would love to hear about a tdi jetta with propane injection.

What do you think?
