I'm looking to start a group to design an engine and release the design as open-source. The goal is to have a family of engines that is elegant, modular, and motorsports competitive. If you are interested in helping, please come join us:

ummmm.....?

 

i dont know how you gonna pull that off since most of the engine stuff is patented.

unless you come up with some original idea but then again what are che chances of if beeing open source.

endyn makes honda heads dart makes blocks, what exactly is the point of this?
it will allow me to cast my own engine block in the backyard?




>>>>>>>>>I'm no engine expert by any means,<<<<<<<<<<


you should be if you starting a project like that
because if i was to start an open source phone OS i would better be some kind of computer genius or able to hold the group of researchers together( cashmoney etc)



race engines are built like that, thats why the parts are expensive.
do you know how much force does a cylinder have to hold up to from combustion and to compress the air?

how are your modular sleeves gonna hold up in it? and also modular means bigger.

 

Mean effective pressure is pretty easy to calculate. I'm an engineering student, BTW.

The product isn't the primary purpose of this project; learning is. I guess I need to continue reiterating that. And I guess its more of an open-source design study.
Even with dart casting blocks and Endyn having heads cast, they are still limited to Honda's architecture. As amazing as that may be, Honda still designed it for mass production, and performance compromises were involved. There's still more to be had!
This really is less about the product, and more about the process.

 

well theres the type-r motors and s2000 that is designed for more race in mind.

honda does build race engines as well, they have their own race team... and so does every other company.

i would think that the production design comes from the sucessfull race engine design and not vice versa.

there are many different engine designs if you consider how many car companies there are, they spend gazillions on research.

you right the casting is limited to honda only because its a honda engine and everything has to bolt on it properly and in the right place(acessories i mean)
im sure then could cast a dodge block with honda engine mounts but who would want that in a honda?

the honda engine has prooven to be a solid built base for a race engine.
i just dont see how it would change things, it still takes time and cost of metals to cast a head for example, thats what we paying for.

i mean dont take my words as a stop sign, if you really feel like you can do it dont stop, but do the research about the engines before you invent the bicycle again and waste your time and money...

 

raverx3m - Chill out bro. its not a bad idea and if you don not want to be involved, just step back and close your mouth. God forbid someone for thinking outside the box.

If we did not have people like this, we would not have many of the amazing innovations and products out there today.

killer_siller - Keep thinking outside the box my friend!

thanks,

 

Good idea.

Local Motors has been somewhat successful using a similar approach:

http://www.local-motors.com/

An 'open-sourced' based car design, created and voted on by a community of engineers and designers.

 

This is fabrication forum , lots of people come here who have no interest in honda's. Stop being so closed minded.

 

well its a honda fab forum to be more specific.
and if anyone have ADD read my last sentence, i didnt tell him not to do it, i just said research whats out there before wasting your time on inventing something thats already been done and something that is patented.

its a discussion forum you people need to chill out as well.

 

Actually it is not a Honda fab forum it just happens to be a section that is part of a forum that is about honda's. Welding and fabrication has nothing to do with honda's its a skill that you can apply to your honda or any car. People are allowed to post anything they fabricated , even people have posted cigar boxes they made and wood projects they fabricated.

 

If it makes anyone feel better, I'm currently voting for an engine with 90mm bore centers: Same as the B-series.

Go to a sports-prototype race and count the number of engines using production blocks and heads. You won't get very far. Real racing engines, even when sharing basic dimensions with production units, don't come out of production factories. They are manufactured in low volumes with specific qualities in mind.

I intend on putting together a group of people to learn how to optimize a design to suit those qualities, and do so in such a way as to also make it economical to do produce in low volumes. Having an open-source project and a "learning" attitude gives me, and anyone else involved, access to resources you wouldn't normally be allowed to. This, in and of itself, is allowing me more opportunities to learn.

 

Honda created some fast yet reliable street motors.

Group B homologation created rediculously outragious barely streetable motors with compromise thrown to the wind. Try recruiting some of those retired engineers if you want a street motor w/o compromise.

 

Well, formula SAE is basically a prototype racing series and they use mostly existing engine technology, that they try to perfect on.

Even group B was a compromise, hell, everything in life is some sort of compromise, but I dont see the point in reinventing the wheel. "Real racing engines", what is a real racing engine anyways? Alot of automotive series run homologated engines, unless its a run what you brung comptetition and that homologation costs alot, so this open source engine project wouldnt most likely be a homologated engine, thus it wouldnt be a "real racing engine".
