made this one awhile ago. this was my first attempt at making an engine out of knex(although its the revised version). its a 32 valve, dual overhead cam v8 with a roots type blower. this started out as a simple piston/block assembly for my engineering project in order to demonstrate torque/horsepower relationships. however, i kept adding on as i had plenty of pieces left over. turned out pretty cool.
This is AMAZING!!!!!!1!
hello i'm a dutchman, how build you the valves? <br>post the instructions. <br> <br>jente105
that is <strong>AWSOME</strong> but what does john lenon have to do with an engine.<br />
Huh? You should see me now.<br />
i'd rather not, im sure. thanks.<br />
It would be WAY Better if it was a Rotary engine.
doubt it. it would have less moving parts.
It would still be way cooler, i think you just can't do it. And you'd be the first to do it.<br />
i made a 4 cylinder engine. the valves do open on time all the time with the cylinders. have yet to post because im adding some very cool "extras". i think the valves dont open on time with the cylinders on this video from what i can tell.
Inline 4 or V4?
inline i posted a vid<br />
yea it doesnt. i had it set up originally but the chain broke off a few times and i didnt bother to set the timing again. even so, i was forced to make a 2 stroke instead of a 4 due to the lack of gear ratios knex offers. i believe you can make a proper 4 stroke using some gray wheels and rubber bands... but it was out of my scale. well, i'll look forward to you post!
ya i know what you mean. i had the same problem be fore. and i didnt know it was a two stroke. good luck.
Any chance of posting? Also what is the song used?
the song is Clubbed to Death by Rob Dougan<br />
&nbsp;K thanks &nbsp; &nbsp; &nbsp; &nbsp;: )
hay when r u gonna post the turbo cause i've tried to make one but i keep failing
wow, this is the single knex model that is actually respectable...
your crankshaft broke at 0:56 lol
this is a great motor ! but, the output (the place where the car will be powered) you could replace the red cogs with something smaller, mayby?
post the instructions plzzzzzzzz it looks like an drag engine plzz post 5 stars
Thats fu***n awsome!
no one on this site makes a engine with a chanable gearbox!
Thats because it connects to the engine and makes it look weird. So instead of whining build your own gearbox there are a couple posted here and on youtube.
i have,with a engine to power it
Very, very nice! You should post instructions.
Wow, amazing.. Nice job!
Yeah I've seen this video about 4-7 times but five stars. :)
