We took our 2005 six speed Corvette on a 223 mile run today. Driving conservatively, we finally broke 35 mpg with a 35.0756 mpg run. Previous bests were 34.4, 34.7 and 34.9 done last year. After driving 10-12 mpg musclecars for 40+ years, this is kind of nice. Horsepower and gas mileage too. Gotta love it. Oops, can't do that. It kills gas mileage in a hurry. I was curious to see if the Varam intake would make any difference. Gains appear to be negligible at best. What am I doing? This is no fun way to drive a car like this. With the improved gas mileage, we are still not saving gas money. We just drive three times as far.
