How to Build Horsepower Seminar


Whats covered in the seminar

  • The overall topic will be a detailed explanation of how to build horsepower.
  • This will include the following:-The power box event chain - this shows how all the main factors interact.
  • How to get air into the engine. Demonstrating the #1 factor limiting airflow and therefore output.
  • Looking at the ways to minimize this by superior cylinder head design.
  • Included in this segment are:-
  • Why the CR used is so much more important than is appreciated.
  • Why big ports don’t work.
  • Why polishing is usually just cosmetic and often cuts power.
  • Why the 75% exhaust to intake ratio (valve size or flow) is so often misunderstood and often does not apply.
  • A comprehensive breakdown of important aspects of air flow management
  • Including: - Why having a high cylinder head means little if there is no real understanding of just how the air needs to be used.
  • Why certain numbers/engine parameters rarely mentioned in either magazines or online performance forums are key to torque and consequently power output.
  • Why most fuel coolers (cool cans) fail to increase output.
  • Why so many carb selections compound the spec errors of the rest of the engines spec.
  • Why most engine builders fail to make the most of a good two plane intake.
  • Why most engine builders fail to fully utilize the air flow potential of the carb, intake, heads and exhaust.
  • Then there are dyno testing issues rarely spoken of such as:- Why so many published dyno test results are unintentionally bogus or misleading.
  • Why changing just one aspect of a dyno test is usually a bad idea.
  • Why improving your specing and engine building skills can drastically cut the cost of a race winning engine.
  • It’s possible to give away hi-octane fuel to your competitor and leave yourself in a better position to win.
  • How, virtually 98% of the time, to optimize the cam, first time around so saving on dyno time and test camshafts. 


  • What are these seminars about?  Simply put the subject matter is ‘How to Build Horsepower’. Unlike most seminars the group is very much limited (10 max) so that it becomes almost a one-on-one learning session.

  • By who? Presenter David Vizard is primarily a highly experienced and qualified engineer who, through his race successes, (won five championships in one year) has become a university lecturer and a very widely publish tech writer with 35 books and over 4000 magazine article alone to his credit as well as a huge following.

  • How long? The main seminar is two days, typically a Saturday and Sunday subject to an additional bonus day on friday If posted (look at the dates).at no additional expense for some hands on demonstrations.

  • How much experience? David Vizard did his first cylinder head flow tests in 1958 and tested his first engine  for flywheel hp in 1961. He has been doing this  on a weekly basis ever since.

  • How good? After 30 years of delivering seminars on this subject to highly qualified engineers, experienced home engine builders, university students and seasoned top echelon race technicians David Vizard’s satisfaction rating is over 99%!

  • What can I expect after attending? Typically most attendees come away having learned techniques that allow them  to build 50 to sometimes as much as 75 hp more from a typical 350 CID V8 and make more money doing it.

  • How much $? The fee for attendance is $500.

  • Where? Most Seminars will be held in the DV shop in the Charlotte NC area. Beginning in 2017 seminars will be carried out at various engine shops across the country. If you are not winning enough races to get yourself a championship win then David Vizard most certainly has what you need. Engine builders who have attended his seminars have literally, won thousands of races and hundreds of championships.


Itinerary

The regular seminar is a small group of usually 10 people or less, With adequate one on one time with David Vizard himself, 2 full days of activities, subject to an additional bonus day on friday If posted (look at the dates). on friday if you can make it in early. projects and lectures. Flow bench exposure and learning of Davids new "Flow Bench IPO" porting software and a tutorial of another brand new software called "TorqueMaster"



Bonus and free stuff

  

   We have some ideas of sharing some free (really interesting) information that most of you will find valuable. I am sure through the web-page in weeks and months to come. Also some of Davids sponsors have generously offered to donate products for promotional sweepstakes, promotional give away etc. While both I and DV are against making this into a circus some of the offers are things that most sane folk would find difficult to turn down.... Well I can't share the details at this time but check the web-sight once a week or so to see when and what may come of this. At the next few Seminars we are giving away some new innovative software before it is released in its final retail form. This has been years in development. As a beta release it will work out bugs beta testers will benefit from the free evaluation copy as well as the final release.

  What will the two programs do for professional engine building shops?


First

here is what the ‘TorqueMaster cam selection program will do:- ‘TorqueMaster

  •  With just 7 inputs (bore, stroke, CR, intake and exhaust valve sizes, rocker ratios and peak power rpm) it will deliver hyper accurate answers for cam LCA, duration of intake & exhaust, cam advance, required minimum valve lifts, idle vacuum, dynamic CR, cranking pressure, torque output, hp output, required cfm of head flow to meet power level, & port cc for best results. NO OTHER PROGRAM ON THE MARKET WILL DELIVER THIS COMPREHENSIVE INFO.

  •  Once the cam specs are calculated the user can search a data bank of profiles to select a cam that matches the selection within a degree or so. Currently this selection has a combined flat and roller plus hydraulic and solid selection of OVER 2200 PROFILES. The required profile can be identified in about 30 SECONDS!

  •  Unlike cam catalogues the data bank not only delivers the LCA and duration figures you find in a typical cam catalogue but also lobe area in inch/degrees plus (and this is a first) absolute intensity.

  •  Again unlike other cam catalogues TorqueMaster will also make a cylinder head recommendation for the most compatible match between cam and heads – in about 30 seconds. But it does not stop there. You can also find the best rockers for the application – also in about 30
    seconds and the same goes for the rest of the valve train. After that you can apply ‘Torquemaster to figure the best intake and carb by part number, again in almost no time flat.

  •  How effective is TorqueMaster at producing power? Very - those who have tried it so far have seen big gains in power while the cost of the build has decreased but customer value has not.

  •  With this program it is possible for the engine shop to sell a cam to a customer who will pay via credit card. The part # then tells which cam company to email the order to. The cam company then drop ships to the customer and bills the engine shop. That’s profit without any human interaction. The engine shop could be selling cams at midnight!

Second

The IOP flow program. The advantages of IOP over any program available are:-

  •  Apart from delivering the port flow numbers (imperial or metric) IOP calculates many other factors including:-  Mean port velocity

  •  Port flow efficiency

  •  Calculated Mach #

  •  Expected torque & HP

  •  Port energy

  •  Specific port energy density

  •  Port area at the minimum point

  •  Valve area

  •  Port to valve area ratio’s (pop-up gives target range) There are numerous pop-up comment boxes that steer the user to the optimum port characteristics. No other program will do this. Follow the recommendations and the user will produce top performing heads

 

   Initially only seminar attendees will get these programs (free), soon ​to be​released​ at a very minimal cost will also spread soon to professional engine building shops.
