David Vizard and K&N will offer both seasoned and amateur engine builders the opportunity to learn new, unique skills to take their engines to the next performance level. From April 20–22, 2012, Vizard will present his lecture series “How to Build Horsepower” at Universal Technical Institute in Rancho Cucamonga, California.

Vizard has more than 50 years of experience in engine design and development, with one goal in mind—finding the right combination of parts that deliver peak power and performance. Engines are complex, intricate pieces of machinery that contain hundreds of individual parts. In order for an engine to make good power and performance, you need to select the right combination of parts that will work well together. In fact, it can take an engine builder many years (and usually thousands of dollars) to gain knowledge and experience to identify which combinations work and which ones do not.

This weekend-long, 16-hour lecture focuses on finding additional power output from an engine in areas that may have gone overlooked or were misunderstood by the engine builder. Follow along in Vizard’s 144-page book as he explains the technical side of camshaft specs, the valve event, compression ratios and more.

Guest speakers will include:

  • David Woodruff of Design Dreams LLC
  • Roger ‘Dr. Air’ Helgesen and Bryce Mulvey of Dr. J’s
  • Bob Verbranic from The Carb Shop
  • Rick Sperling and Tony Mamo from Air Flow Research
  • Mike McClelland from Professional Products
  • Bob Scheid of McLeod Clutches

The David Vizard “How to Build Horsepower” seminar will be held at Universal Technical Institute, 9494 Haven Ave., Rancho Cucamonga, CA 91730. The weekend will begin Friday evening at K&N, with a social event planned for conference attendees. K&N is located at 1455 Citrus St., Riverside, CA 92507.
