Lego V8 - more refined

[plaaplaaplaa12]

horsepower?

[DJSI3434]

what is the crankshaft design crossplane 90 degrees or flatplane 180 degrees

[DavidDMAN22]

What does it run on? oil,gas,electricity? Please reply!

[nicjasno]

@DavidDMAN22 neither. Compressed air.

[vivalarey619]

what are the chances of compressed gas replacing internal combustion engines?

[magnum9987]

VERY NICE. I wish REAL V8s operated this smooth....

[squirrely911]

Now put a supercharger on it..

[ilykefishiecrackers]

this is incredible!

[theCyte]

this is the smoothest running V8 Engine i've seen so far. I really want to built that exact motor, because thats simply the best construction there is yet. Do you think you cold create a plan for that one, too. I have seen the plan for the older model still with a belt but this one is so much more beautiful.

[nicjasno]

The LPEpower V8 is MUCH MUCH better and alot smoother. Go check it out. I even sell the things on LPEpower . com

[14gco]

hey were do you get one of these lego kits

[nicjasno]

You can get them in my store. I make them. LPEpower . com

[p51mustange1]

how do i get a lego tach

[farcorfe337]

Where can you get the rpm gauge

[IllegalMavamaarten]

Woaw... Running it @ 60 RPM looks awesome :O

[j5drumr]

you are amazing! viewing it at slow rpm's are cool cuz you can see more details

[Honda2x409]

how do these engines not melt? dont they heat up?

[nicjasno]

No. They don't heat up. They are actually cooled by the expanding air.

[TheShane132]

@nicjasno it really runs on gas

[nicjasno]

It runs on compressed air.

[kratosjlv]

Dude your messed up lol, jk

[somebody5788]

From what I've seen on every video of these the largest problem is air flow. Why don't you guys add a 2nd air intake hose? or 3rd or 4th. I realize at some point you will prbably start melting things but I mean why not have some fun haha.

[skylorz]

make a gearbox and clutch a put i in a car

it is greate!!!

[josh101744]

how long did it take you to build it?

[stevensj13]

I dare you to put your finger in there >:)

[jonatharivera]

lol i was laghting to death

[cheshire03]

This is really nice, but I wouldn't pay the asking price of 310€. You could make one yourself with some standard k'nex and rubberbands for less then 40€... Infact I have about 2000 k'nex peices stored in my closet somewhere, I might make an engine myself.... Plus where's the fun in buying something pre-made when you can get the joy of building one? For you viewers, I'd say buy a tub of k'nex and with a little imagination and knowledge you can make a nice working engine.

[nicjasno]

Good luck!

[cheshire03]

Thanks but I won't need luck :) I've been messing around with my old k'nex for a little bit and it's very do'able, ont as hard as I thought. Not to mention I get the satisfaction of building one myself for less then $15 or 10€...

[nicjasno]

Well, the pneumatic elements alone cost around 80 euros....

[cheshire03]

I have a few small cans that can hold compressed air as well as a compressor in my garage so it wont cost me anything. I might make a little dune buggy out of k'nex and put the engine I'll make in there. I'll just rip apart my old remote control car and use it's parts. I just have to have a little servo to activate a lever on the can to release the compressed air to power the engine.

[nicjasno]

I'd like to see that. Post a video when it's done.

[cheshire03]

Well I work a full time job and have other responsibilities so it'll take a good while, but I'll see what I can do. I used to build RC helicopters so this would be a fun little project.

[ArcadiaCv]

What is being used to track the rpm?

[nicjasno]

A lego speed computer. Sadly they're not produced anymore.

[vastenmielinen]

i remember i once built a w16 engine ,but it broke and i dint know how to do it again

[AlchemistHawk]

when you buy it, does it come preassembled?

[nicjasno]

The LPEpower engines all come preassembled and prelubed.

[jessejames288]

were u get 1

[WpA09]

nice engine!

can i have the instructions please? :D

[nicjasno]

No. But you will able to buy it from wednesday on on w w w . L P E p o w e r . c o m (without spaces). Actually a much better engine with more power and more rpms.

[WpA09]

ok. thanks!

[warlock91]

nah its no fun unless you get to build it yourself

[DeathlyHand]

Are you using compressed air?

[nicjasno]

Yes. Compressed air.

[AOO08DOYOUHEAR]

I would like to see someone run it at higher and higher rpm's until self destructs. But that would be sad to do to something that I imagine took a lot of time to build

[nicjasno]

It would not self destruct. A hose would pop off and the engine would stop running. The engine can't go faster because of various reasons. Some of them are: Valve timing, crank twisting, switches... It would not self destruct.

[AOO08DOYOUHEAR]

You could not get it going so fast that the rods would disconnect? or the crankshaft would come apart?

[nicjasno]

No. It can't run faster than on this video.

[bf2modsde]

that wont last too long without some oil :D

[LPEpower]

It's all lubed up with silicon lubricant. No worries.

[Iamnotaliberal]

What you should do is put these engines in lego race cars and design the transmission and all that, then get a bunch of guys who've built lego engines to do the same thing, then race the cars. You could put the pump on the car and make it radio controlled so you can control the pressure to go different speeds and even add a pneumatic brake system. It would be so awesome.

[rigger084u]

if you make me 1 ill give u a tenner for it

[sh3lbot]

what you going to throw it in :P haha jokes. cool stuff tho

[sampusaf]

wtf!!! is this thing really a mini engine that produce power?

[nicjasno]

Precisely. You can buy such engines in my shop on w w w . l p e p o w e r . c o m .

[laurence265]

sounds like it needs oil...lol.. i wonder if you try some sewing machine oil..

[Brummbrummquietsch]

Respect. This is awesome.

[dirtjumpdaniel]

Where do u get the RPM gauge

[blindassassin111]

now did you do this is it in a set or did every part come seperate?

[faluffsen]

weare did you bye the Lego V8

[zark76820]

THATS UPSIDE down

[petem1989]

upside down? It's made of lego, and its not a four stroke engine. Anyway, the cylinders are in the same place they would be in a four stroke, so how is it upside down?

[Vinc717]

coooooooooooooooool

[tucsondog]

you sir,

are a god.

[tk10]

do the pistons get heated when running full rpm?

[pagani8]

No, it would have to be running at like 5000 rpm and for a long time for the friction to really make it heat.

[petem1989]

It also helps that the air cools as it expands inside the cylinder. This somewhat counters the heat generated from friction. You still have to lubricate these things though

[gonzow0815]

pls tell me how to build one ^^ pls

[EvolveVolvo]

is it air powered? electric? very cool

[MathiasDenmark]

Where did you get that ? :)

[Wisetorsk]

you are a true master builder

[HisXLNC]

Sorry about the horrible grammar in that last post.

[nicjasno]

Np. I get the idea. I'll try to think of something. I'm very curious myself. Would make tracking of the development easier and i would know hen i'm going forward or backward.

[HisXLNC]

Have you ever tried to measure the power output of the engine?

[nicjasno]

How? I don't have a dyno.

[HisXLNC]

I was thinking would could be made somehow connect your engine to a small electric motor and voltmeter and convert the milliwatts produced into horsepower. I think it's something like 1 milliwatt = 1.3*10^-6 horsepower. But i'm no genius. It's probably not that easy in real life.

[viper2788]

hmm i dont know about achieving hp but torque can be figured out. just add a rod to the end of the crankshaft and (somehow) measure the force at the end of the rod. that force multiplied by the length of the rod is the torque. then again, you'd have a curve and max torque/rpm would be a b!tch to figure out

yeaa just a suggestion, i wouldnt measure it lol nice engine btw

[HisXLNC]

Isn't horsepower just a function of torque?

[viper2788]

well not exactly... they have different units. hp is ft*lb/sec whereas torque is ft*lb.you'd have to multiply torque by engine speed to get horsepower. but like i said, tryin to measure this without a dyno would get complicated.. you would have to integrate since you get different power outputs at different rpms. uggh i just struggled through a summer course on this crap too =/

lol lets keep it simple.. just build and ignore the numbers!!

[azerrlight]

horsepower is 765 watts or somthing like that which is 765 joules persecond

[azerrlight]

horsepower is 765 watts

which is 765 joules persecond

[petem1989]

It's now gone from sounding like a diesel to sounding like a turbine! This looks really smooth and powerful, great stuff!!

[randomguy9898]

man that is awesome. i wish lego had the parts in there pick a brick that you could sell these.

[Zblj1987]

Good job Alex!

Again :)
