Building 4.6/5.4L Ford Horsepower on the Dyno

The photos in this edition are black and white.<p>The 4.6- and 5.4-liter modular Ford engines are finally catching up with the legendary 5.0L in terms of aftermarket support and performance parts availability. Having a lot of parts to choose from is great for the enthusiast, but it can also make it harder to figure out what parts and modifications will work best. Building 4.6/5.4L Ford Horsepower on the Dyno takes the guesswork out of modification and parts selection by showing you the types of horsepower and torque gains expected by each modification. <p>Author Richard Holdener uses over 340 photos and 185 back-to-back dyno graphs to show you which parts increase horsepower and torque, and which parts don&apos;t deliver on their promises. Unlike sources that only give you peak numbers and gains, <i>Building 4.6/5.4L Ford Horsepower on the Dyno</i> includes complete before-and-after dyno graphs, so you can see where in the RPM range these parts make (or lose) the most horsepower and torque. Holdener covers upgrades for 2-, 3-, and 4-valve modular engines, with chapters on throttle bodies and inlet elbows, intake manifolds, cylinder heads, camshafts, nitrous oxide, supercharging, turbocharging, headers, exhaust systems, and complete engine buildups.
