I know for fact with a gasoline engine you can have your cake and eat it to.LOL
With my project I started out running a 11.3 @ 130mph in the 1/4 and
0 to 60mph in 3.17 seconds.
Plus, on low boost 8psi it autocross very well.
Its fun to run a car at the track that will beat ZO6 Corvettes and some all out drag cars.
From there I thought if this 1.6L Honda engine can perform like this at the track, I wonder how much of and improvement can I get from the stock fuel mileage??? So far a personal best of 74mpg.
I have some friends in the Honda community that are running 9.40 second 1/4 mile times and getting as good as 45mpg.
You will see more and more of this in the coming years. Utilizing small displacement engines with today's EFI turbocharger technology is the new performance of the future.IMHO
