Oversized valve?!

So what is the purpose of removing the quench pads? Does detonation increase or does it not change anything besides combustion chamber size

how much can pr3 head be milling ???

wohh like a dream come true NICE

ช่องพอร์ทไอดีที่เป็นหลุมลูกกอล์ฟไม่ได้ถูกถอดไกด์วาล์วในขณะที่สูบอื่นๆถูกถอดไกด์วาล์วออก ซึ่งมันมีผลกระทบในการตรวจวัด เพราะในช่องพอร์ตที่มีปริมาตรเล็กกว่าจะมีความเร็วในการไหลของอากาศที่เร็วกว่า

What was the density of the air on each configuration flow is not the only factor to look at

wa the fuck was that number tho. we dont know which is better on that 3

Great video but I don't understand the values. Could you please briefly summarise which surface has which value?

You should hog out the old cylinders first with a tool then send in the boring tools to spec.

I'm building now a d16zc motor. pg6 nippon piston with floating pin ,h beam rods, brian crower stage 2 cams, port head, itb, vtec killer pins

preferential dimpling would be the best. You can tune velocities in specific areas with that technique

Now come on... the valve guides are waaay too long , they hang into the port waaay too mutch. Dimples allso not gona work. I know supposedly , supposedly it should allow for more flow. But it ain't gona.

Respect for the job that you’ve done. I know it’s a lot to ask, but I would still like to ask if you would be up to share a 3d model of mashing so I could do the same job on my head. I’m of course ready to generously contribute.:)

I know nothing about CNC.. Why dont they use some type of cutting oil? Seems like, if nothing else, it would extend the life of the tool.

Even IF the dimpled ports flowed slightly less, they would still make more power because of better atomization of the fuel mixture.

That's what Ilike to see!

Beautiful! What are those dimples for?

How much would this cost 2/1/2024 🤔

Hello..can the 1984 733i 3.2 cam be swapped with the 3.5 same type engine??I know it has more lift and stuff but will the valve/piston clearance be ok..??

What sorta performance gains would one expect from this?

How much?

Do you have befor and after flow bench numbers . Especially intrested in mid lift results.

What is the Head flow @.600 lift 28in water?

Unfortunately, no offense that was the most useless video on cfm, dimpling lift,, etc. especially for people that want to understand. Not a single word, single spec, before and after.

Amazing

How much cost it??

Just give it forced induction. Turbocharging or supercharging. Then all this flow bench nonsense becomes obsolete on redundant.

nice! what cfm?

Very impressive! How much is that kinda workmanship these days?

Я думал для супов будут делать , что то посерьёзнее....печаль

🤪

Nice

ua-cam.com/video/soo3O21RP8Y/v-deo.htmlsi=mNoA_BgRsHA9hKrp Exelente trabalho nada a apontar muito proficional !! Obrigado 🙏

amazing porting & polishing job!

I wish I could work so smoothly

You have a CNC vertical hone and you’re not using a head gasket and torque plates?!!! No way I’m bringing my block to you.

Why no flood coolant system while machining the block? Was the block junk to start with? Why trash a perfectly good block? I can’t believe you could get the proper tolerances specified by Darton for sleeve installation.

Build the engine with this head, tune it, dyno it and monitor the EGT of each cylinder.

e70 X5m (s63) working?

If this works, we will find this in all F1 engines, right?

Dimpling your intake ports is a waste of time as they have virtually no effect on performance. Also it reduces your vol. efficiency a bit. They look cool though.

Beautiful to watch, even if the cutting rate was a little too fast; swarf that thick can surely damage the finished face !? It's a shame that the other commenters don't know why Beryllium seats are used - Doh !

NO dimples on F1 intake ports > WHY ? A port is NOT a golf ball travelling through air ! How could anybody believe your video results, I suggest that the yellow line is the dimpled port result

Cool ,don't you have to add material to the camshaft to add duration of lift to it ?

what's the purpose of this?

С какого метала сделаны седла ???

Середина провалена .

Из какова материала сделаны сёдла клапанов ???

А почему седла латунь ???

i hate this company. put videos on you tube send many email not answer they can put there dimples where the sun is not shinning
