how to modify piston ( extreme )

[@TheGreatInquisitor]

То чувство, когда у тебя капремонт, а поршней на старый двигатель в продаже нет...и ты натыкаешься на это видео. Вы, таки, дарите людям надежду, мой друг.

Can't believe I've just sat and watched someone destroy a piston!

[@scottyjones27]

I'm not experienced in piston making I'm just DIY fix my stuff man this man here lives on a rock in the middle of the Pacific ocean he has had to make stuff work Not as intended if I was needing my scooter fixed on said rock i ask this man how to !! I'm sure his scooter is the fastest on rock

[@trxtech3010]

@@scottyjones27 Deffinatly not. As someone who has biuld many engines here this guy has no clue what he is doing. Also using a Cast Aluminum Piston o make a high compression piston is a horrible idea.

Como você acha que as coisas são fabricadas? Principalmente em lugares onde não há recursos tecnológicos! Lembrando que tudo em seus primordiais eram feitos em máquinas manuais operadas por humanos e o produto final funcionava sim...

it is scary but I suppose it may run. this much machining, where I live would make this A golden piston

Where would one be able to buy the Eyeball Dialling-in Precision Tool you seemed to use ??

You can find it in most hardware stores. Hit Or Miss Ltd, Close Enough Retail, Screwed Again, etc.

How thick is the piston crown after that much machining?

[@KULITEHNIK]

approximately 5mm , with this shape the valve part is very close to the piston ring ( people order )

[@thefreedomguyuk]

Not thick enough....

[@hiperformance71]

@@thefreedomguyuk it depends of the application, from what I see, 5mm can be enough for a Naturally Aspirated engine

[@horahore5175]

@@thefreedomguyuk it's enough. Use 13:1 compression ratio. Huge valve, stroke up, extreme camshaft profile upgraded Ignition, porting polish, proper cooling will boost the horsepower from 14 to 30HP minimum

How to modif piston so good

[@williamgilchrist8577]

I understand what you did and the methodology you used to reach the end point. What was the piston used for to begin with and what did you modify the piston to fit into for use? Unless I know that then all I see is someone just cutting some aluminum. Maybe I am just thick or something or something but I do not see why you modified the piston. I have to assume you modified the piston for a racing application.

[@hiperformance71]

from what I see, he has a "sporty" piston damaged (is broken in the crown, first 3-5 seconds of the video), took a piston with huge compression height (distance from the compression ring and the top of the piston), and made some machining to copy it the crown. from a machining point of view, the guy has amazing manual skills, no doubt. From a thechnical point of view, if the objective is to make this engine more "compressed" instead of buying expensive forged pistons (the one he copied is clearly a forged piston) it may be good considering the costs involved, but for performance point of view, is no way, the sporty piston is lighter and stronger, the piston he used to modify is cast aluminum, it is heavy compared to the sporty forged one, but, I can understand, when you do not live in a rich country, you need to adapt at what you have, is like "made it in a budget" but more extreme way.

[@Hydrogenblonde]

He is just making a replacement. The engine maybe getting bored to the next oversize.

[@92gashaulass43]

Yes for modified cam and bigger valve size,need more valve lift clearance due to modified cams

lain kali kalo bubut piston jgn di tekan gitu,lebih bagus di buat dudukan ke pen piston saolnya nya kalo di tekan diameter berubah,pengalaman ku

Buy raw dome pistons,LHK brand is most popular hyperteutic piston choice With great quality but limited in pin size

Saya pastikan itu piston goyang, kurang presisi

I'll just buy a Wiseco piston

[@hiperformance71]

the problem probably is, that the country where the guy lives is not as rich as US or the EU, probably he can buy 8-10 sets of pistons with the money you can buy Wiseco pistons, some peoples need to adapt to their economy/environment.
