That's a cool write up.
I'm one of the freaks that has to have both, performance and economy.
Its been a ten year dream for me to have a 1.6L 2300lb car that can make 450+whp and get over 90mpg (74mpg is my current personal best) and run 10 second 1/4 mile times (11.8@130mph is my personal best no traction on drag radials).
The 450whp part is done that was easy. The hard part is my fuel mileage goal. But I'm sure I can get there. I learned a lot this summer with this engine and I have some more in it when it comes to mileage. I hope my new aero mods will get me to the 90mpg mark. Plus it will help the top end in the 1/4 mile.
I also plan on autox the car this next year and do a 12 mile hill climb.
It would also be nice to see what it would do in the standing mile.
