- This(episode 43 part 2) is the second half of Richard Holdener's 2.2 turbo Chrysler's head porting. In this DV covers the results of the first half of this video and shows the flow, discharge coefficient, port velocity, port energy, and specific port energy of the intake port developed. He also goes on to explain the next moves.

I love living on maui it's got the best weather & women on Earth! One of the inconveniences is I'm on a different spot on Earth and every time somebody has a live feed on UA-cam I'm still at work. I.e. 6 hours later than the East coast! 3 hours later than California! To my favorite UA-cam channel! Thank you!
DV teaching us the mysterious art of
getting well stirred mixture past that valve.
Mr. Vizard, Much respect here, Thank you for taking the time to explore and develop this cylinder head. I daily drive an '85 GLH Turbo and it is an absolute blast. Mine has been treated to the next iteration of this cylinder head the "swirl" Combustion chamber casting and mine is intercooled and set up much like an '86 Shelby GLHS Omni. Once again thanks for these videos.
I am also much into the Chrysler Slant 6 engines and plan to port a cylinder head for my '70 Duster. Will employ the knowledge that I collect here!
I don’t know how I’ve just found this now. I’ve been a huge fan of DV since I got into Minis in the 80s (but still a kid). DV doesn’t hide a thing. He just spills his knowledge to the world! If any of the younger viewers are wondering what this older gent has to offer, you’re not looking hard enough. If you’ve heard of Dave Mountain (or specifically Mountune) then know he was one of DV’s apprentices! So happy I’ve found this channel!
DV, hope all's well with you. Very much appreciating this series!
I've been waiting all day for this video. I would like to see you port a set of 5.7 or 6.4 hemi heads.
I'll volunteer my 6.4 heads!
Is it true that you use WD-40 for air freshener in you car ? Lol. Nice to see you again David and thank you for the knowledge
Mr Visard, thank you for the Mopar content!!
Thanks for all the knowledge you're dropping on us Mr. Vizard. Between reading some of your books and watching your videos here on youtube I have learned a ton of useful things. Thank you for everything, please keep making videos and keep the knowledge coming for us, it is deeply appreciated
Same here 👌
Good to know you are feeling better, Mr. David.
Hey David, I see your editor has stepped his spelling game up 😜 I was beginning to think grade school kids had the job ;) I cant wait for the 421 build, as I need inspiration for my Vega which has a vacant engine bay currently, and coincidently I was eyeing off some discounted Chevy 400 blocks the other day too..
Owch !
I really enjoy all the Advanced Theory and applications.
Your personal experiences shared also David.
Love Race Math and Advanced Calculations Calculas. But it's you Tube must be friendly for all viewers.
Loving this content! Still have the book
Thanks David. Hope you’re doing well. Regards.
Thanks for your time Dave.
Thanks for all the videos. Some time I will have to do a straight 8 Buick head of all things.
Thanks for video!
Another excellent episode. Hopefully you get a head to cut up and have a look . Cheers DV
Thank You again Mr Vizard!!!!
Learning Much from your Videos David. Thanks .
Sweet like seeing more from you dv
Thank you DV .
Big fan, I have a set of mon o war 18 degree sbf heads if you have not seen any in person. I am 50 miles north of you, if you want to see a few neat features in them I can bring them. I think whoever made these have been watching your videos.
🔔😎
EXCELLENT!
THANK YOU, SIR
😎😎
Love all your videos. Do you have in mind to do a video regarding Ford FE heads?
Ok I see what you are saying. You opened the flow a lot. Ok this is boosted.how does the swirl come in on the boosted motor. Turbo pushes naturally aspirated pulls. This is why I watch you so I can find out the facts from a person who knows what they are talking about. Thank you for your time and going to enjoy your work on this. Most of all I can’t wait to see the arm chair pros fix this for you. I forgot to ask you dose the boost make the swirl on this?
Both a N/A and a boosted engine work the same. You have a higher pressure area trying to fill a lower pressure area. More accurately you have a higher density volume trying to equalize a lower density volume. Make it easier for the higher density volume to fill the lower one, you will probably make more power (give you can get it out, too).
This head is such a turd. But gotta love polishing it :)
Really enjoying watching this.

Great video! It would be great if David could cover the big block Chevy peanut port head. Richard holdener did a fairly impressive peanut port build and I wonder what David could squeeze out of them.. maybe larger valves, port/bowl cleanup? The supply of reasonable oval port heads is drying up.. no one want the peanut ports, but I’m not a rich man either… Can David make a silk purse out of a sows ear? Thanks!
Gearhead - don't remember what Richards results were but I can tell you they are better than generally credited.
Hi mr David...i have watched all your video, but non of this video you make flow test on the 4 valve cylinder head.. how to make the platue for the exhaust port in 4 valve cylinder head??
Mr. Det 2 sir, 4 valve is coming!
@@marvingvx1 ok Mr.David... i will follow all video that you made...
Great video David. Would I be correct in thinking that the missing swirl has transformed into tumble? Or do you suspect that the airflow is now chaotic? I often think that we focus on swirl because it is very easy to measure and quantify. Tumble however is much more difficult to measure and quantify so I feel that we overlook it. I often wonder what difference we get in performance between heads designed for tumble vs swirl? I realise that this question is like asking you how long the bit of string is that I am holding here whilst writing this, but maybe you could give us some information based on the basic principles/characteristics of the two different methodologies. Thanks again for another great video. Regards from Perth, Western Australia, Greg
Greg, been to Perth (love it) about 4 times over the last 30 years. Have a good friend their. But to answer you question - no tumble of any consequence either.
Tumble is not generally a characteristic of 2-valve wedge combustion chambers. Maybe hemis and 4-valve pent-roof chambers, but they have to be designed for it.
👍

Am I to logically assume that this info applies to all turbo set-ups? One would obviously need to know WHAT the air is doing in their particular assembly. But it seems to me, having watched all of your video's, that, within reason, this information translates. As an example, I'm contemplating how to apply this to a Chevy LY6 engine (6.0 block, LS3 square port heads). I have some, and want to make a torque monster out of one, for a mud truck.
Chrysler changed the combustion chamber design on the 2.2 engine from one that was sort of a bathtub to one that was more open. Does this head have the early or late chamber?
David, Have you ever done any work on air cooled VW heads?
are you going to make an exhaust manifold recommendation to Holdener-- say a 3 into one, x diameter and x length primaries?
Yes sound issue
Cleared up after a min or so
👍💪
I've found that a 420 head from a dodge neon flows much better. I suggested this to him but he wants 8 valves
It definately does, but it requires some work for oil drainback and timing belt.
@@bigassfordsd I think only the 2.5 tall deck 86-88 block works with the 420 head due to valves hitting the pistons. and the nightmare of wiring...
@David Vizard, If Richard Holdener and you need a "G" head to do the final porting on I may have a spare. I am in the Seattle WA area. Then you could cut up the worst one of the two. Richard Holdener has my Email addy too. Send me a RMA and I'll box it up.
Dave, I would send you an RMA right now if I could remember what it was. I am guessing it is a 'something' mailing address - yes.
I may not get your reply via this UA-cam site so email me at my web site:- davidvizardperformanceseminars.com
Many thanks

Sure didn’t take much to kill that swirl. I have engine builders tell me all the time it does not matter at 4000+rpms though. They tell me flow is worth more hp than swirl. I have my doubts.
Hey bcbloc02 They are not entirely wrong here but also there is more to it than meets the eye. Will get into that when I cover swirl and combustion efficiency.
I see what your doing bc
I hate the L/D ratio axis. Why can't you just use lift ? You didn't change the size of valve but nobody is gonna know what lift you are talking about.
Mr. Vizard, I just sent you an email regarding another 2.2l head that I have and am willing to give you for sectioning if you would like it. 1986 Turbo Lebaron.
Uh oh. Sound quality problem.
