- In this, episode 46 of PowerTec 10, DV goes into detail on porting Chrysler’s 2.2 liter 2 valve per cylinder heads. Though they are only average in stock form they can be made to deliver a considerable amount of extra power without necessarily adding significant boost thus enhancing reliability as well as power output

With your videos, just as with Richard Holdener, during the intros, I go ahead and hit that *thumb up button*. Because you already know there is going to be a lot of valuable information coming!

Hi David, my first porting job was of a stock 1974 Chrysler Avenger back in 1981. I copied the dimensions from a Tiger head a friend of mine had. It had a “3/4” race cam and twin side draft Mikuni 40mm carburetors with chrome trumpets. What a beautiful sound. Thanks for the memories. Please try a Toyota 3SGTE for your next 4-valve porting series. I’ve done a few of these and would like to compare notes.
🙇🏾♂️
It's been so long since I've seen the 2.2 Turbo. That's a peppy engine, from the economy era of the 80s, that is an interesting project idea. 🤔🤔🤔
its allways a pleasure to watch a new video from david. allways something to learn from a master.
Many thanks for this presentation David, finally learnt how the port mouldings are done. Many thanks 👍
Thanks for sharing you hard earned knowledge. Loving it
I don't want him as my accountant..."episode 30" is episode 47 lol.... great wisdom he has...yes!
Find a new hobby
Information well received on my end. Thanks David.
Looking forward to this mini serie
Funny thing. I was running copper water lines in new houses when I was 13 years old! Dad would have beat me if I ran anything that looked like that port! Well he would have made me fix it at least.
Love your videos and I am always looking forward to the next one.
'...dad would have beat me...', do you wanna talk about it? 👻
Hello David, first I will send my best wishes to have a great 2023. I always liked your technics and the way how you teach us, I tried to find episode 45, to know more about the Inlet and Exhaust ratio, but I found this; David Vizard's PowerTec 10 EP 45 Crank Journal Polish = + 20 HP? . Is it in an other episode of yours? Thank you so much for doing these videos, I would like to know more about turbo engines mods.
The FAIT 600, 850, 127, Autobiachi A112 (Abarth), Uno, Cinquecento and Seicento al have bathtub shaped combustion chambers.
I always wondered how to prepare the chambers. But this and the second part helped me out quit a bit. Not all. But more will probable come.
The nasty thing of the above mentioned heads is that they have an intergrated inlet manifold inside the head. Yep, true. And bad. So a mold can be made but will never come out in one piece. Simply because the space inside is bigger then the openings on both intake and valve seat sides. A perfect bowl is also impossible to grind due to the big space inside.
And so the only side which comes close in performing David avizard a tricks is on the exhaust side. ...but may be I'm wrong and do not see what others (you) have already seen?
Wow, those are some weird shaped ports. My only experience porting is with a l-series Datsun, the exhausts needed some touching up but I pretty much left the intakes alone.
Thank you this is fascinating
Happy Holidays
Another great video can't wait to see the end results. I'm sorry to put it out there every time I watch your videos for years as you post a picture of your daughter you really is me. I have a lot of kids a lot of daughters and and my oldest daughter will be 24 in January and she has a lot of mental problems especially with people she was raised around in and friends because she's not like them. Saying she's more normal and they want to take her to the other sides. So every time I see your daughter in that picture I think and do whatever I could do to help my own out. Sorry to go on a rant but I understand my youngest just turned eight and she's awesome just like your daughter was on my daughters are awesome but the things we have to put up with now and the stress and what people do against people is terrible. I just want to thank you for what you do to help people out with knowledge You're amazing man and one day I will go to your class I've been trying for years just a lot of surgeries.
So it WAS you who did the Avenger turbo.
Thanks David you've just won me a free pint.
Wonder what they would have used for a gear box? 😆
Thanks!
What surprises me the most is Richard isn't in the comments. Least a guy could do is blame a squirrel on the port alignment.
Awesome vidja 🤙🏼 AWOO
David does Richard have the head now, I saw him building a 2.2 I think it is starting out stock. I hope your camshaft input gets validated
Please analyse a Superbike head, would be great to compare the efficiency and flow characteristics of those engines too.
I really love this stuff, very interesting. Do you still teach or have a school to learn hands on ?
I've also always wondered how those molds were made. I thought you had to split a head with a band saw and plaster mold it, didn't realize it was rubber 🤦♂️
🔔😎
Thank you Sir 👍👍
Another great video with a great deal of information. If you ever get the time, us Pontiac guys would love to get your take on improving D port heads. I’d be willing to send you a couple for research purposes.
I'd like to see Mr vizard play with a sr20det or a ka24de. Maybe even a rb20det family. That would be awesome to get his input. I would watch it for sure.
This is nowhere near the sins that were perpetuated in the Volvo 2-valve heads from 1964-1997.
I know, I’ve 3D scanned, modeled made a finite element model of Volvo B20, and OMG what a horrid exhaust port. Working on a B230FT head now and indeed what were thinking with those L shaped intake and exhaust ports, it’s like a straight 90 degree bend .
@@AndySomogyi at least the B20 port can be filled with bronze and the inlet made with a good shape. That bathtub bowl adds to the misery.
@@iansmith6728 yup. Interesting thing is if you look at a Porsche 944 head, it’s the same single came, valves in-line style, so it can’t cost any more to produce. But the 944 has an ideal wedge combustion chamber and almost perfect port design.
I’ll bet manufacturing costs on the 944 and Volvo B230 heads are identical
On a 4-valve engine, I guess the mold gets pushed out the other way? Or do you split the mold?
👍💪
great info,if you know any horse power secrets about the fe ford i would be very interested
Can you send me a link to episode 45, i was trying to find it., i have a turbocharged engine, and would like to figure out my intake to exhaust on it...
I've heard David saying that wedge chambers are superior several times. I'm wondering if he has a detailed explanation for it being better or if it is more based on empirical evidence.
With David, it won't be his opinion, it will be empirical evidence. Bath tub chambers suffer badly from valve shrouding, and the wedge chamber has much better mixture distribution as a result of the quench action driving the mixture towards the spark plug.
@@theshed8802 Good explanation. Thanks.
Richard do you think oversize valves would help this 2.2 turbo head? Looks like the intake valve is already greatly shrouded in the chamber, but the exhaust valve area has room for growth, what does the master say?
I was wondering if there's much that can be done on the 2.4 tiger shark multi air engine as far as boost exc.
I definitely know of a Dodge Dart running a turbo on the 2.4.
There's a few out and the company that was doing it got cut. With all the big heads looking out. It'll have to likely be one of project on my part but I have done a few of these kits make them easier. But it can all be fabbed up. I may just move it into a hydrogen run platform that way it will pass all emission requirements. Without being a problem see how our country has changed in the last fifteen years. Can't do anything without a stamp. 😗👍
What do you think of possibly using a thermal barrier coating in the exhaust ports after you shape them to help prevent the heat soak into the rest of the head?
Porsche did that on their older turbo motor. Maybe in the 944???
Ceramic I think was used
@@Christdeliverme, I think Honda used sheet metal shrouding(?) in the exhaust ports on the CVCC engines too
Cerakote makes a piston coating but I don't know if it would hold up in an exhaust port
There were/are(?) companies that ceramic coated headers, inside and out as I remember. Also, some manufacturers are integrating the exhaust manifold into the head. Maybe they have a way where the heat can be kept from transferring through the surface of the exhaust port, maybe an alloy that resists heat transfer?
PFAS! 👻

I found you through UTG and the 318 build, I have a Chrylser 2.2 turbo and will be looking forward to these episodes. Please loose the background music, your content is music enough.
Plumbing 😂
Those shapes are awful.
