Introduction: K'Nex V8 Engine

Picture of K'Nex V8 Engine

This is a V8 mod of Geonovast's V4. Also, see the video of it meeting it's demise.
And, this is over 3 months old. I never got round to posting it.

Hey does this actually work? because ive got a knex car chassis (About 3'x2') and this would make a perfect add-on. If it does work, how much power would it crank out? if it doesnt, do you know anything like this that does work?

Well, seeing as how in a real car the combustion is what creates the power so since this does not have the ability to com bust. The power output is zero, you need a motor such as a drill to make this work.

Well i know that. Of course you need a drill. I want to know how much power this needs to move and how much it cuts down on torque. Also, how much power can it take before it starts to break.

Right but what you asked isn't the information you're trying to get. You asked "How much power would it crank out" meaning to me your asking how much power or (HP) it could put out by itself.

too much free time

ajleece (author)koal12010-01-17

Or lack there-of.

until its finished anyway

 Someone should get all knexers on this site together and make something life- size and amazing like a full size car featuring this baby for example. Someone popular who lives in a good area with millions of knex should do that it would be so cool!

ajleece (author)ant ant 332009-11-10

Awesome, but unrealistic.

mettaurlover (author)ajleece2010-02-06

Actually, the best way to do this would be to have various people make different parts, then bring them all together and connect them to see what happens. For example, I know how to make a relatively stable wheel as far as k'nex goes.

Smasher555 (author)mettaurlover2010-07-24

Good idea.

mettaurlover (author)Smasher5552010-07-24

Remember what I said earlier about acceptable time limits? That was outside them.

Smasher555 (author)mettaurlover2010-07-24

It's not your bussiness to tell me what I should and shouldn't do. End of discussion.

mettaurlover (author)Smasher5552010-07-24

In all fairness, what I'm saying is general politeness. People don't particularly like getting mails about replies to comments old enough that they don't remember why they said it.

Smasher555 (author)mettaurlover2010-07-25

Whatever. BTW, I said end of discussion, so drop it.

ant ant 33 (author)mettaurlover2010-02-07

 yeppp sounds good. we'd end up with a 30ft alien thing with a vivsector gun on its back, twin z35s and striker pistols on its shoulders!!!!! awwweesssoooooonmmmmeeeee

mettaurlover (author)ant ant 332010-02-07

Not so much the guns, but parts like the roof, wheels, axles, doors, etc. And some of the guys with epic amounts of k'nex can make a few D-TAB's and mount them on the hood so you could fire them from the front seats...

That leaves the problem of moving the thing; all k'nex has in the way of motors is pathetic little things, so it'd either taker a ton of them or a much larger, not meant for knex motor.

ant ant 33 (author)mettaurlover2010-02-07

 we should install a v8 engine!!! a real one with a real car chassis

ant ant 33 (author)ant ant 332010-02-07

 or, if you seen avatar, a robot thing that someone goes in and it replicates their actins

mettaurlover (author)ant ant 332010-02-07

That would make a much nicer build, and have more places to add motors unobtrusively to looks.

ant ant 33 (author)mettaurlover2010-02-08

 errrrr. ok? unobtrusively???

this motor is from knex innovation .com isn't it

ajleece (author)gerrits132009-11-16

This is a V8. Not a V4. The one on KI is either Geonovast's V4 or my V8 mod.

ajleece (author)2009-10-22

Apparantly you can't see the pictures. Here.

Looks good

Mr. Muggle (author)ajleece2009-10-24

that looks cool, 5*. and man you have a lot of knex

DJ Radio (author)2009-10-22

Put pics in a comment.

travw (author)2009-10-22

I can't see the pics.

Oblivitus (author)2009-10-22

LOL!, you should add some slow-mo clips to the video.

Killer~SafeCracker (author)2009-10-22

I can't see the pictures man.
