A lot of good suggestions in above replys..
I would add one seldom mentioned tip:
Try to find someone near you that has a
Mazda Millenia S with its factory installed double superchargers V6 that runs on the “Miller Cycle”
and see if they would let you drive it, or do a ride along, etc.
https://en.wikipedia.org/wiki/Mazda_Milleniahttps://www.carthrottle.com/post/mazda-once-made-a-225l-v6-and-its-spectacularly-complex/https://www.newcartestdrive.com/reviews/2000-mazda-millenia/If you are looking for a boost in fuel economy AND power
understanding the Miller Cycle
is a good way to learn how.
The Miller Cycle can run on one or two turbos, not just with double superchargers like the Millenia S.
Double superchargers are easier to program an engine computer for,
as their output depends on rpm,
and not the volume and temperature of exhaust gas varying second by second.
sample quote
This car really comes into its own when its Miller-cycle V6 is put to work. Mazda’s unique Miller-cycle engine was named one the world’s “10 Best Engines” by Ward’s, an automotive trade journal for the past four years. It uses a Lysholm compressor — a scroll-type supercharger — to boost intake pressure along with late intake-valve closing to produce an impressive amount of power without sacrificing fuel efficiency. This system allows this 2.3-liter engine to perform like a 3.3-liter engine, while still retaining the 2.3-liter engine’s economy of operation. The result is a vigorous 210-horsepower with the brawny, quick response of 210 foot-pounds of torque. The Miller-cycle package has no downside.
