    The YouTube videos I am posting are meant to cover these topics broadly. I have purposely omitted all mathematics, formulas and equations related to the topics being covered. I have been told as well as witnessed myself how fast you loose an audience when math formulas are involved. Basically I cover the WHY I did what I do and not the HOW I do what I do. There is no substitute for learning in a class room environment with fellow gear heads. That’s why I have reserved the HOW I do it for the (Induction Dynamics) classes that will be held at BES Racing Engines later this year. Anyone who has previously attended one of my classes will attest to the mental drain it inflicts after two days of absorbing discharge Coefficients and other formulas.
    If your interested in attending one of these classes please email me at
    darinmorgan7854@gmail.com
    Please don’t call BES as I am handling all registration and class scheduling. The guys at BES have enough to handle. They are busy busy busy.

      I have completed a one and a half hour, three part series on fuel distribution and deatomization in the intake tract. Since I don’t go into great detail on wet flow in the seminars we will be conducting at BES I decided to expand on it and present it on YouTube. Since my broadband connection sucks it takes 6 hours per video to upload. Should be uploaded by this evening and I will post the link as soon as it’s available.
      This is a subject matter no one has ever talked about. This will shock a lot of people and dispell a lot of myths.

              When I took his class many years ago it was ten miles over my head. I even bought a calculator that did things I never thought a calculator could do. Have I used the formulas??? No. Did I learn enough to justify the cost??? Yes. I built my flowbench with the ability to measure speed VERY easily so that took a lot of the math out of it. I more or less idiot proofed it. I have books that I’ve bought over the years formula heavy that I’ve never read either. At my age if he offered a hands on class I would probably pass on it now but I sure wish I could have taken one 20-30 years ago.

                    People talk about it you just have never heard of them. The entire Hot Rod industry is built on MYTHS and these myths are continually perpetuated on forums by self proclaimed experts that all dance to the same tune. Go look at Larry Widmer and have a think about what he's doing and how he can run 21-1 comp and he's not the only one either. Funny how he talks about de-atomization but doesn't mention how its atomized in the first place and how to improve it before it even gets to the port to mess it up.

                    There's a ton of science on this stuff and the sharp guys read it and apply while the others just play follow the leader. Its interesting what he said about the LS7 head and loss of torque.

                    Looks like what the fuel does is more important than what the air does..........Guess maybe just maybe the engine isn't just an air pump after all.:lol:

                      I haven’t watched it yet so I’m behind the 8 ball as far as what he said. I’ll try to catch it on my desktop this week after I get all
                      My tax info gathered for my Thursday appointment. My buddy (Tim) also a Mopar nut was lucky enough to take classes from Joe Mondello. Tim taught at Wyo Tech and retired several years ago but still builds engines, does porting work, and races so we have some good discussions. Tim was very upset when I told him Joe died as he would call him with certain issues and Joe would tell him how to approach it.

                      When you do it will make for some good discussions.

                      Mean while those who don't understand will just want to argue.

                      My head ported was also schooled by Joe Mondello. He is very helpful n this area, love to talk/teach others about it. One day I hope to get into a lot.

                        It's funny that the end was chop off like that.
                        But with my first flow bench i used a smoke machine, that we used to find Evap leaks(gas vapor leaks in a automotive fuel system). When i worked at a dealer ship. Where the smoke escaped it would leave a trace that you could pick up with a ultraviolet light. would jump right out at you.
                        I sneaked this machine home one day and let the smoke feed in to my head/flow bench. at different lifts it made different pattern. But not knowing what i was seeing and unable to take a picture or video of it. And only had one night to experiment with it. I didn't learn much from it.

                        One other thing you can't run methanol or any other flammable liquid through a standard bench with out creating A BOMB.
                        Even spray paint would eliminate the usability of your bench afterward as there would only be splinter of the bench afterwards.

                        Too expensive to buy but if i ever go the chance to barrow one again. it would be fun to try again.

                            Wait he's talking about creating swirl in the chamber and how that affects power production.............:rofl:

                            What's a Vortex again.....Look at the chamber starting at 21.17 and think about its shape and what its doing to the intake charge as it enters chamber.

                            Remember these statements I made earlier in 2 threads about porting and heads that got certain people angry:

                            Now that its "Darin Morgan" telling you this you might actually listen.

                            So at 16.40 he talks about how the cylinder goes lean even though you give it an AFR of 12.5 to 1. That's what you need to think about.

                            Now ask yourself why some engines want lots of timing?

                            Thanks PBR for all the links. I need to catch up. I do know that I spent a ton of time reducing swirl. Swirl takes energy. I know for a fact that most people reduce swirl. I remember reading about all that swirl, tumble, swirumble, twirl and such and I can say all you are doing is crutching something.
