Building 4.6/5.4L Ford Horsepower On The Dyno (Original Edition)

By: Richard Holdener .

The 4.6 and 5.4 litre modular Ford engines are finally starting to catch up with the legendary 5.0L in terms of aftermarket support. Having a bunch of parts to choose from is great for enthusiasts, but it can also make it harder to figure out what's right for you. Building 4.6/4.5L Ford Horsepower on the Dyno takes the guesswork out of choosing parts by showing you what kind of horsepower and torque gains to expect.

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 are just a waste of money. Unlike source that only give you peak numbers and gains, Building 4.6/4.5L Ford Horsepower on the Dyno 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 and exhaust systems, and complete engine build-ups.
