Much respect DV. Hope Eric takes your offer. I never miss an episode from either of you...Eric is a stand-up guy, I am very interested in the potential outcome. I think he'd come away with a different view

I think you are brilliant, you have much respect from most of us ! We are so fortunate to have your instruction ! You don.t need to defend yourself from the critics ! You have been respected for 60 yrs. ! God Bless you David !

If your critics were engineers they wouldn't be. As an engineer myself, I ignore those who aren't. I love your channel and keep those episodes coming!

I have a PhD in engineering and 40+ years of engineering research and I’m a critic of DV.

I watch you both now. Im hoping this settles down,as you both are gentlemen with loads of talent.

There is wisdom. In a multitude of counselors.

Glad to see this. I like both men, and I appreciate both of their efforts in this hot rod community. I would like to give a perspective that I believe will help others relate to and by doing so-open their minds to the way things are in this life. I’m 45yrs old right now. I have tinkered with anything that had an engine since I was literally 5yrs old! At 7yrs old my dad got upset because I had pulled the 3hp tecumseh engine off of the garden tiller and put it on my Bigfoot (power wheel) with the tiller clutch and chain! He was so impressed tho -I think he refrained from taking his belt to me! Over the years I became more and more involved with mechanical, electrical, paint, body, welding, and how things work. When I was 16-18yrs old.. I really thought that I knew a lot 🤣… and now at 45, I can tell you that I have more to learn than I probably have years left! One thing I have learned is that there is a delicate balance between explaining how knowledgeable you are and boasting. This balance is the difference between someone trusting you to do work for them and someone else thinking you’re nothing more than a blowhard! I understand that, and I have listened to people who in very short time convinced me that they were simply full of shit-simply by the over the top claims they spat out! Most of the time I was right in my assumption, but there were a couple of times that I wasn’t-and what I did was assume a posture towards those people as to say that I wasn’t interested (assuming it was a farce) and as a result I turned away extraordinary opportunities by doing so🤦🏻‍♂️! My point is that unless you have truly gotten to know someone…you cannot doubt -the amount of things that a person has experienced for themselves, the amount of achievements that they have accomplished, or the events that someone in this life has witnessed! You know whats said about a person who “assume”(s) things! You can be an expert in a specific area and still have a great deal to learn- Once a person believes they know it all…there is only one thing that can be concluded-that person is done! Keep an open mind. What you will learn by doing that-is that the “other guy” has knowledge you need and vice-versa! THIS-is how we move forward….not through division 🤝❤

Omg!!😂😂😂 " why am i still seeing ladies that look 80 years old? Cause the shit didn't work!!" Just about peed myself!😂😂😂

I listened to this entire video out of respect for Mr. Vizard, and so I wouldn't miss potentially important info. I made my opinion known about internet pissing contests last video so I won't repeat it. I hope that Mr. Vizard can find his way back on the path of finding and sharing new information in the automotive space. The last couple of videos have been disappointing and concerning. Wishing you the best Mr. Vizard.

I've unsubscribed from Eric's channel a long time ago since he could teach me nothing of value at all. The knowledge that I gained from DV's books and videos elevated my skills to an above average level of sophistication. No "one" person can tell you everything, however DV has taught me more than any one else. Thank you for sharing your knowledge and keep up the good work. Much appreciated.

I follow both channels already. Both you guys are good at what you do.

Sir you are legend. Its also priviledge to be interested and good in your work that you do it even old age.

Love Eric's channel. I found another channel that's actually 3d printing intake ports and chambers and flowing them on a flow bench. Fusion 360 is free to hobbyists so rapid prototyping of these ports and engineering principals are easy to test accurately. It's really easy to test the geometries. I'm just waiting for generative design to become more available to hobbyists so I can set the important geometries for connections and everything. Then with the generative design I can have it run sim after sim to find the ideal shape and length for the given intake tract.

That sounds interesting would you mind posting up the channel details as I would quite like to have a look at that.

I would love to accompany Eric on his visit to your laboratory! I have great respect for both of you! I have used your knowledge over the years with great results and Eric humbly offers his learnings with the notice that his word is not gospel and he's just telling us what he has found

David, I only wish I had heard of you earlier and was able to attend your seminars, please don’t stop. Love the content, we own an Eco Boost Mustang also so bring it on!

David your knowledge so valuable. When I am doubt I silently do my own research. Intercooler companies need a good kick in the pants with their claims.

I watched Eric’s video and appreciate all the great info he gives and I agree he was respectful in his response to you. I expected the same sort of response in return and you delivered. I hope Eric accepts your offer and comes to your shop.

Hi David, watch Gold's Garage in the next month, Allan is building 2 identical 302 Chevys, I'm doing the heads, one with a 45 seat and one with your 30 seat, we will flow test and dyno both to see the average numbers , it should be interesting!! Keep being you!!

The oil of Olay comments are priceless lmao😂

Grape Nuts! Oh the malty taste was terrible. You had me laughing good!!! Stay healthy and please share more 4v head porting for turbo applications (BMW?).

Amazing attitude DV. I think Eric is man enough to come by and visit. I can't wait to see. You guys team up.

Eric is a good guy I am definitely a fan

18 min of my life I will never get back. What is the point? Eric’s objection was the number of dyno pulls. Nobody can know how many dyno pulls every other person has done. Let’s move on with real tests and data

I've been yelled at by better. I've never doubted your knowledge. Appreciated you preserving and passing it on to us.

I think the best way to handle this is to take two sealed GM crate engines (604, or whatever they’re called). The only mods allowed are a custom spec’d cam by each contender, and head porting work done by each contender. Nothing else other than valve spring upgrades to support the selected cam. Then, a dyno battle royale where the winner takes all bragging rights.

I really hope Eric takes you up on this! He has a very good channel and some interesting content. However, I believe he could really benefit from spending time learning from the master!

David. I respect you and your knowledge of tuning engines. You may not always be completely right, but you have plenty of proof that most often you are, or at least close enough to it to win races. Please don't turn in to a bitter old man screaming for people to "get off his lawn". This is the internet, trolls are abundant. The only sane way to deal with them is to ignore them completely. Anything else feeds them and when you passed the gates of the Internet, there was a clear sign that said:"Don't feed the trolls." Please take that to heart.

I am starting to wonder if DV is starting to get Dementia... My grandfather would get angry as hell at the very slightest thing! DV is really sounding strange , especially with his threats in his latest video and his overall anger he has towards this issue! DV just sounds like a bully here...

David, one of the problems with being in the firing line as an expert (I don't like that word) is that if you wrote 3000 pages of technical articles a lazy person will try to condense it to a single line. Hypothetically if you found a small inlet valve worked in a very specific scenario you would be misquoted all over the internet as though you condemned large valves in any situation. I see this in other technical fields, often the "expert" is drastically misquoted or the information is presented out of context. If perhaps you do a livestream with Eric it would be better without the chat box, people on the sidelines often enjoy stirring more than learning. On a comedic level "how to modify your Mini" would not be very helpful if it had one page and one line saying "buy a Hillman Imp" 🙂

WELL I LIVED THROUGH THIS ! 🤦‍♂️ I have read many and own many of your books, been a subscriber shortly after your first channel, before you lost your friend. I have been a subscriber of Mr.Eric Wingartner right after he started his channel. I HATE THE DRAMA ! I have heard his story and yours. I agree that the perspective, from you, Mr.Visard and Mr. Wingartner is the difference. No Matter how thin a pancake, there are still two sides. I really hope the two of you can get together. I am 60+ and would really just like to have more good content and increase my knowledge. I have been at this type of work now since I was 14 and I still desire to learn something new every day. Please, both, keep your ego's, but display humility and gain subscriptions by great content high quality knowledge. Let's leave the drama for other channels I don't watch. Thanks

Shots fired !!! Will be look for the meeting, if it happens.

I always like to say PROVE me wrong and I get smarter. Until your able to that, shut up till you get smarter.

David, I look forward to Eric becoming even better at his trade, by learning from the best. That would be you sir. Please don't spend your precious time giving a rats butt, what your jealous wannabees, sling at you, like a monkey in a low budget zoo. I am a HUGE fan of yours, and I want you to be happy. Jeff Thompson

I subscribe to both yours and Eric's channel. I think you are spot on. I am no expert, nor have enough experience doing what you do. But, I have a brain, and will mull information over until I can see the logic in what is being presented. And I use Andy's channel, Darin's channel, Charles' channel, and quite a few others. Enough to almost resign to just saving money to send what I want done to the experts. But my sense of adventure drives me to "play" with the information I have gleaned from yall. Thanks to each and every one of you. Now, if an expert could thoughtfully explain to me the need for a split duration on an LS camshaft, I would be grateful.

Eric is or was a school teacher as I recall. Makes sense that he is somewhat level headed.

When I spoke with DVin person, he was quite quick to mention that the people before him were and are really smart people with whom without he wouldn’t be where he is today and was quick to give credit too. DV is well schooled and smart. This is obvious. He backs it up with his testing for the facts. He is also a gentlemen. Don’t confuse his being sure he is correct with arrogance. In person, he has acknowledged and given credit where credit is due without hesitation. Also, on a personal note, he has personally apologize to me for what he felt. He did wrong to which I assured him there was no harm and no foul and told him to just brush it off. As far as I’m concerned, he was a standup guy.

Eric has had a lot of testing specifically with LS heads. Perhaps some of the suggestions he makes may actually work. Either way go about it gentelmenly!!!!!

I sent a note to Eric to get back to you…. Hope you gents talk. Both of you are better than this. Thanks for all you’ve shared with us. I’m hopeful you’ll share the Olive branch too.

Best regards Julien Dubray

Ok, Walter Mitty

David I luv ya, don't waste your time and your students on thing that don't improve our auto engineering knowledge! Thank you for your listening ear!

The only thing I have a hard time with? How many dyno runs have you done? I know it's a 💩Ton though. I have flowed your books and learned a lot from them. I always wanted to attend one of your seminars but never had the funds to do it. I have been porting since I was 18 years old and now I'm 51 and I'm still learning. No, I'm no professional at porting but a back yard hobbyist. Great Video Sir, And I'm still watching EW channel.

DO NOT FEED THE TROLLS!

If anybody is a critic DV in a negative Way, this is fine. Those of you that I think he is arrogant, should not confuse being sure of himself as such as arrogance. After meeting Dave in person, he has been quick to give credit with credit is due and was humble about the whole entire matter. He was also thoughtful enough to apologize to me on something. He thought he did wrong. In my book, he did nothing wrong, but this is a personal matter that is not going to be talked about. But I state as a testimony to his character. After spending a few days with David, the bottom line is, I can say he was a standup guy. Humble, kind, considerate and thoughtful. Arrogance was not part of the program. I think too many people being sure of oneself with arrogance. This is the furthest thing from the truth with David. I have nothing but good things to say about him. Look forward to meeting him again. In the video where he says with the story of the grape nuts, that he just wants to bring out the truth with the facts as carried over into his work career and it shows. If you can prove him wrong, do so with the facts! I’m sure he will give you credit because that’s the kind of person he has presented himself. He has done this in the past, giving credit with credit is due.

Nice job on this video….hope you guys chat….

Well stated David!

david....when it comes to some people "you can't fix stupid" as the saying goes. this also conveys to those who are emotionally and sociologically bereft.

David if you're in Scottsdale Arizona you're welcome to use my engine Dyno anytime. I only met you once at your small group seminar. What people don't know is that you're actually a very humble person. The biggest problem with KZread and the Internet in general is people typically only want to be entertained. Hopefully some day they see the value of what you and Eric are trying to do, is educate. It would be nice if both of you could get together and do some testing. I'm sure the gained knowledge, would help all of us learn more and get better at building horsepower.

Much of your contribution to this industry has had relevance, but a lot of what you’ve done has been developed further and a fair bit of it has been proven wrong. Some of us have taken the time to learn more than your work taught the industry, and along the way we have proven many of your claims and hypotheses incorrect and misleading. (Scientifically speaking you hypothesize often and have rarely reached the burden of proof to claim a theory). What Eric Weingartner says about being humble is factually why I don’t hold you in the highest regard and only pay attention to what you do as it relates to fundamentals. Your ego is showing in these rants, which is why I seriously struggle to accept anything you present blindly. Stop telling us how great you are and show us, or continue these silly comment response videos all the while hurting your reputation and legacy at the same time. I want to respect your integrity and contribution but I’m finding it harder by the day.

This whole situation is descending into ridiculousness. I think you and the other guy should delete these clips going back and forward at each other and move on with a bit more professionalism and dignity. I cringe watching these clips between you two. It's actually embarrassing for both of you.

I walk away from poisonous people/YTchannels/etc. I was getting tired of his whining, un-scientific testing methods anyway. Putting down someone with many decades of experience was the last straw, so I left that channel. Sorry, David, I can't grant your wish, I actually unsubscribed from his channel. He needs to earn my respect - which he lost just recently.

I have been watching both of you Men for a few years now, and learn from both of you. I hope you get together, that would be interesting.

Mr Vizard every time I hear a story about your life I realize you have lived though a lot as a young man. There is a reason you've survived all of it to be here today to share your knowledge. Also don't let the trolls get to you as you can't have a valid discussion with them. As the saying goes don't argue with stupid people they will drag you down and beat you with experience.
