Thanks Darin - David Vizard strongly recomended we pay more attention to you and he wasn't wrong. Your laid back nature and putting technical terms into plain language we can all understand is invaluable and I'm learing so much Thank You
Yes please to a live chat. It expands the topic in different directions and ads to the whole subject. If after this cast. People can ask what ever comes to their minds after this. It is kinda like expanding everyones imagination and possibly uncovers or exposes more of Darins vast knowledge. I will probably re watch this atleast 5 or 6 times to absorb everything discussed. As there is so much information in between the lines. This was awesome! Thank you. ❤
Darin provided us with straight talk when dealing with sometimes deep technical subjects. The visual aids he provided added another dimension and enhanced his presentation. We need to thank Darin for putting all that together. Much valuable information here and more to come from this knowledgeable, experienced man. As DragBoss indicated, viewers were treated to a no-cost lecture-seminar and can replay it at their leisure for anything that may have been missed or for anything needing clarification. Thank you, Tim and Darin. Look forward to seeing, hearing and learning more. Pass the word along. Like and Subscribe.
Thanks Bill. It had me on edge of my seat. With those slides helped so much to clarify what I was thinking when talks of harmonics and flow. Just down right enjoyable. He will be back I 4 weeks for just questions and answers. Just did not want to stop him during the presentation. Yes and feel he deserve and revenue from this, to compensate for his time and giving this knowledge freely.
@DragBoss351Cleveland No worries. If they come back, they can speak up. Darin is a walking encyclopedia of heads, among other things, I'm sure. Getting his Mellon sparking seems to be right down his alley for a hip shoot, Q&A. So, me, I'm like you. We absorb what we can and figure out the rest later. My question was posed to dozens of self-proclaimed gurus over the past forty years with no answers that ever made sense. Now I know and will never forget. Thanks DB
@kenmoule825 right O Ken, it’s one of those things, people before, probably didn’t know the differences. I think your right many don’t know how to explain things so us common folk understand.
@DragBoss351Cleveland Or they don't understand what is actually going on. 🤔 I'm not into any flow bench work yet, but I'm considering it. Two strokes are easy, really cheap to do, very limited machine work, and the principals remain the same regardless of the heads design. Applying sound techniques with some math, some art and some science is always good. He throws stuff at the "wall," so to speak to see if it will stick. Everyone enjoys a happy accident, but we learn more from the mistakes most times. BE and VE are grossly overlooked by many builders and head porters. Darin knows if that the juice was worth the squeeze, priceless.
Hi Tim! Very good, plenty of information. Good to hear this CHI, intake manifold is a good piece. I must admit, I'm a little reluctant, to do much grinding on this intake, maybe just smooth things up, then run it! Darin, is interesting, and has a good voice for presentation of this material. I will have too watch this a few times, just to "digest" all this information. Very good, take care, my best to your family! The Cougar is back from the paint shop. Progress!!!
Your most welcome. I understand, about taking the grinder. The question is what will it pick up. Are you going to see 20 hp from your combo with porting. No offense but doubtful. Is it worth the time and effort. Now if you want to just clean a few areas up I get it. But from his expert experience not much to do. Yes we talked after and plan on question and answer chat in 4 weeks. Just tough to get to many last night. I did not want to interrupt him too much. We are also working on something that may take this channel to the next level. Just in idea stage. 🤔
@@DragBoss351Cleveland IMO I think many watching, have questions, some general, some for specific engine combinations. I like the idea of a q&a session, with Darin.
@johnsalvaterra3116 I know your be there. Thanks for giving super chat money, it mean alot to not only host but guest. It’s a mean to an end and Darin said to say thank you to you and the couple of others that were generous to help build this channel. 💯🏁👍👍appreciated
@@DragBoss351Cleveland I thought that Darin's presentation was good, without being overly technical. I worked with a group of programmers, aerodynamic engineers, building, testing CFD software. Now my job, was testing, to collect real world data, to allow the engineers, to verify CFD results. I can say it took about 10 years, to build a software,program, that gave believable results, that the aerodynamics engineers had confidence in. So this stuff, is kind of "up my alley " yet still a whole lot to absorb. I appreciate Darin's 40 + years of experience. It really shows in his enthusiasm for the subject.
Tge people you've been able to get on is nothing short of amazing. Cant believe more people don't sub. Keep up rhe great work. Also thanks to Darin and other for sharing.
You're the best! I appreciate your kind words. I have not seen guest like I have. I wished more would sub and help me build this channel. But it is not up to me and I will continue to do my part to record racing history and things you will never see or learn anywhere else. Someone stole and copied some of my lives, working on getting that taken care of. I may make a video on that and expose him. Any thoughts? Thanks Ben
@@DragBoss351Cleveland good on you Tim. Hey I'm getting a new samsung tablet soon. I'll be able to talk to you on skip ect. This subject is neverending. Mike
Another great video brother, finally had a chance to watch, lots of knowledge as always, wish I had a bigger screen to watch this stuff, the long episodes on a phone screen get the old eyes to hurt'n 🤓 keep them coming brother, I have a lot of catching up to do! 🙏
Definitely interested in the live chat, learning a lot from Darin. I’m curious about the effects of different size radiuses to help the air charge flow from the plenum into the runner.
There are plastics that let you print intake manifolds on a $300 3d printer. Its carbon fiber infused high temp plastic similar to what OEMs use. Quite amazing actually that you can do that in your living room. But as Darin says it takes skills in a suitable 3D CAD. Fusion360 for instance you can get for free. So its just about applying the time 👍
It seems to me the front throttle body manifold should have the runners bent forward towards the TB like the rear runner. The newer carbon fiber TF hats are way forward and high up in the air stream and down into the blower entrance. The problem with a 7° divergent diffuser cone is the length needed.
Hi Tim, can you bring back Darin and do a live to explain all that math he talks about at 32:00 ?, pick an imaginary engine combo and let him brake down the math and formulas, I think is the most important topic that need to be documented
Are you thinking about the ledge where the LS3 chamber is wider than the 4 inch bore? That has been bothering me too. Daren might not have caught what you were meaning. The valve is close to the chamber and closer to the bore at a little over 600. I used to cut a bevel on the top of BBC bores for the same reason. How much of a ledge are you getting, about 0.35. I can't help but think something needs done.
,,, Tim, there's a run down of that Buick V-6, that was on the pole at the Indy 500 . In the latest Motor Trend on line , evidently there was no boost reg . ,,, btw, do you have an e-mail ,,, ? ,,, btw-2, ,,, along with bore centers, I'd like to hear more from Don on those Indy pushrod Chevys , like the one that ran so well at OMS ,,, ( Ontario ) .
Hi Tim thanks for an awesome video chat with the master, I wonder if Daren could talk a bit more about manifold design with a roots blower, he touched on this subject only briefly in this interview and it sounds Iike he likes to use the 4th wave for runner length with blowers is this correct and why and what does he do with the plenum volume and location of the discharge pie from the blower, is it best to just dump the air into the plenum or radius the exit.
Hey Brett he will be back with a questions only live chat. Have to ask him, but that could be a whole presentation in itself. I think both, with the boosted pressure, the mixture is forced to port entries and overcomes and slight obstructions. Radius just improves. Idk.
Hey Darin I can definitely relate! I love learning new shit! I am also trying to learn electronics as a hobby. I try to watch all the RU-vid videos. I’m gonna do the power supply project maybe the one using 2 tax power supply’s, not sure yet. It would take the fun out of it if I bought one. I have a fluke, oscilloscope and all the DCA Pro testers etc. I’m enjoying it
BTW thank you so much Tim and Darin! I really really enjoy picturing all this in my head while you explain it Darin just like you said Tim. I rewound it many times if I missed something and I will watch it probably once or twice a month. I hope you get the credit for the views of the same person watches it over and over. I will watch it from my other channel also. SUPER THANK YOU and hope to have more explanations from Darin or somebody that can speak as well as him!
Why don’t you make rubber expanding plugs for the runners so they don’t scream so loud on the mill? I knew you were gonna say that when I saw it just from my hobbiest machine on my Bridgeport
@@kennyrmurray yes keep for sure, see it in your minds eye and watch the flow patterns. I do put it on in garage and will listen when working away. Sinks in slowly. Thanks Kenny
I would argue the Pontiac D-port cylinder head is the king of piss poor designs. Yes its similar to a SBC, just worse in my opinion. Thanks for the great info. Love to DB & Family
Hi Tim! Thank you and Darin for this incredible information! Is there a chance to have Darin discuss 4 valve per cylinder heads at some point in the future??
Why the 335 designation ? Maybe you covered this already and I missed it ? Back in the late 70's you could buy Ford's with Cleveland's in them cheap. You could find wrecked cars with good engines too. I started roaming wrecking yards looking for a 335. Never found one. I eventually asked someone the reason for the 335 ? Someone said " It's a displacement figure. " Thoughts ?
most people like ather makes.aswell and Live chart would be great, if the main focus is on ford most of the time. Already the LS questions are coming through. We are all tirerd and sick cheap GM motors and LS talk if you know what I mean. DBG and your associates are very deer to the Cleveland fans We've waited a long time for this my friend ☺️ mike
Dam it man, that is killing it. Very impressive, I had a 95 glide with built engine. Had the heads welded like hemi. Bike ran 12.80s. I will relay the message to him. Thanks for the donation. I will put it in his jar so to speak. 👍👍🏁🇺🇸
