You handsome devil you!
LMAO!
Here in the USA, no doubt. But! He lives in Europe where gas is a bit more expensive. So a little extra mileage for him is very helpful. Also, why not for everyone else. While it maybe just a toy for you, others may drive there car a bit more than what you list.
(My personal toy gathered just over 15K last “Car Season” alone.)
@Jeffrey67dart How much is fuel for you in Europe? Sold by the Ltr. right? 3.78 Ltr. for each gallon.
Math time! LMAO!
Cam timing is everything. Next to the state of tune and then drivetrain ratios. As you know all three working together cam make great HP but also work for mileage.
While you state that the OEM have used Hyd. roller cams as standard for a long time now they also have the most modern tech within. Most of us do not. If you don’t see a problem with that, I myself and I’m sure a good many others here will be looking very forward to seeing you build thread on making a lot of power and getting high mileage. (Notice how I left that as a very broad ave. for you to travel.) Heck! If you can double the factory power output and retain the factory EPA rated MPG, I’m all ears!
