Looking for more HP
Say Wildthng:
Last time I checked, the laws of physics were still the same.
The power boosting methods of the 1970s apply even in the year 2002. And if you'll look at any normally aspirated high performance 4-stroke engine, you will see careful attention paid to intake runner lengths and diameters and exhaust lengths and diameters. Some of the formulas to determine these lengths were developed by Chrysler engineers more than half a century ago.
