Power tec 10 EP 3 David Vizards infamous 128 Cam Spec formula

hi David Bizon here and you are watching power tech 10 if you care to give me just 5 or 10 minutes of your time then I won't give you the benefit of my 50 years or so of building race winning engines you yes that 128 formula came in for eight beating both on forums and I guess a little on the internet however well most of these people are looking is it works and if you stop and think about this there is nothing better out there there is nothing which will predict the low center lining of this requirement Indian to such accuracy so simply that's assuming that this ten point five to one compression now there's obviously more to that because none of us built ten point five to one compression small-block Chevy's 791 you can build a racer you can be a thirteen and fourteen to one that's good however there are some Corrections that need to take place to allow for changes in compression ratio changes in rocker ratios and well that's about it but there are subjects in themselves here what I suggest there is if you need to know more about that then try getting a copy of my head build horsepower book and I'm pretty sure all the formulas are in there even the correction was or if you want to know about it in detail come to one of my seminars and here along the bottom here is where you go however there are we take a one more step in this is what I'll deal with next so that's a good question where do we get a program like this well the easiest way to get one and the most effective is to attend one of my son of ours this will give you a perfect this program and in the flow bench program for free and the reason that we're doing that is we want professionals need to be the first to be airing useless program just so that they can establish just how useful is also it's going to take about in there two hours of tuition on it so again it's very convenient for me to do this at my seminars so that's the first stage now if you can't make it to one of my seminars and then you will be able to buy this program if you check out what a typical program it's the next best thing to this is worth you'll see you'll be paying between 250 and 500 dollars for of course they won't tell you how to build the engine right down to the farm that I bought and also they won't tell you which parts to use and things like this that's still something to do for those people and we would advise you to be at least a respectable engine builder then this program will be available it's somewhere between 275 and 300 dollars we will make it announcement of that on our website this take much to belief but I make it some pretty good pretty big flames here thing is is the advertising industry is full of people making plans one of the things that you can verify is you talk to people who work with me they can tell you but in every instance what I've told them to do this work exactly what I tell you'll find if you go through a list of top technical writers most of them exist for about 10 to 15 years and then that's it they're played out that are probably going to have enough mistakes where people are fed up with it at second century here we are 50 years later since my first article and over 4,000 of them and I still can't keep up in demand also I have never had a communication from anyone well we did it just that she said it didn't work on the other hand I've had hundreds people say something to the reverse even people said you realize what we learned from you what is a championship well that's not a rare that's common right let me give you some examples my daughter I gave her and her boyfriend he's 17 he's 18 the copy of my book on a citizen's I'm here America they're needed I had no physical contact with other than a book manager like they built an engine to my specification had that book and for two and a half years they literally looked every single professional engine builder out there who built many engines in a two and a half year period my daughter had an 88% percent we record now ask yourself how much experience in a 17 year old girl in an 18 year old boy building racecars they were so dominant that actually beat the factory car and try to find another budget or something is viewed as a budget sure that that I had guys doing and from engines I've built and literally on islands and theatre professionals that does if you can tell people the real world stuff but let me go home how can you establish whether one of the city's true it's quite simple if you're a professional engine builder with a diamond take a look at your last say ten bills that are ten point five to one well ten to eleven to one compression ratio and see what the average peak torque per Keywest this test to prove the validity of what I'm saying is one that I like because I get the opinions of people or I get the responses from people were in a position to act have an opinion that's worth something that is the professional engine builders so let's see what we've got here our test is to see how much torque for a cubic inch engine to produce remember the torque per cubic inches are ready related to the brightening effective pressure then for the last hundred years that has been considered to be the determining factor on the success of an engine in our case we don't have to go into rugby effective pressure because in effect torque it's exactly the same thing with just different scaling okay let's look at some numbers here let's pull up some numbers on the board now if you start looking through the dynamic curves of lovely means to solve them evaluate cetera right especially those where they're trying to put together a whole lot of parts that don't cost much money then although they may be competently assemble and you can expect them to last typical pros in this group and it does represent a big section because cost of building a performance I mean is very influential in customs so one point two five foot pins is for your average Pro now I've seen engines built by guys think they know how to build these that are and they think they're inspired amateurs but are not only making about 1.1 foot-pounds per cube so they build a stronger my purity things less horrible than the boat you made originally with it's more displacement don't want a competent and you know that servicing the main part of the industry ie that's not the guy that something for the absolute cheapest market possible but is looking for a good deal right there are about 1.3 book branch to cube this one called the competent engine builder nothing exciting just a good body from anything right now let's go back to the top 10% of the pros here we see the typical good bill is 1.35 for parents of cute these guys or now they're after performance rather than number of customers sure their engines cost more the journey get much painful so this group here at the tender center now let's look at this one point four for the parents 4q top 1% just check their total some of these professional engine builders that are really top of their rank and they'll tell you getting one point four foot pegs for cute is not easy but it takes skill and knowledge and usually a lot of testing here's the last 10 minutes of these resurrections I've built personally our engines are spec type of my clients they've averaged one point three nine seven to one point four four seven foot panels per cube these are the engines of about a multitude of cameras but through this is a kind of straight off camera master right so you can either have an engine like this but acquiring you can master program or you can sit back and be one of these other groups if you're in this room you know that's good but most of these belts didn't get it first time all of these fields did so this is what I'm going to leave you with you can either do it the hard way and cost more money where you can do it the easy way cost a lot less it's entirely up to you thank you for this you you you you you
