A stop motion/timelapse video of me building the LPEpower V8 for a customer. The camera rig/rail is also made out of lego. :) Video was made by my friend darjanator: www.youtube.com www.flickr.com Music: Clint Mansel - Welcome to Lunar Industries (from the Moon OST)
Stressing the drivetrain to its limits, holding the tire results in the rim spining inside it (the squeaking sound) and then the drivetrain broke off the axle connector inside the rim.
This is my single cylinder Lego engine that does 1060rpms @ 60psi(4.1 bars) and minimum speed is 280rpms @ 10psi(.7 bar). Here are the pix of the engine. s351.photobucket.com Sorry for the shakiness but that's what you get with a 1 cylinder. Thanks to Nicjasno for his website that's was very helpful. Thanks for watching!
Testing a prototype engine. I so hate silicone lego tubings constantly popping out :( Pressure was less than 3 bars and i couldn't rev it out to the max because of the tubings. 1800 rpms isn't that bad though. Still runs a bit too rough, but the sound is there :)
This time with a transscript, but still pretty low production values. I'm learning though. Images on LPEpower: www.lpepower.com Wikipedia on caster: en.wikipedia.org Caster in RC cars: www.rctek.com
Production values have increased even more! Yay! However i still need to work on my spoken english. It simply sucks. Let me also know in the comments what you'd like to see in future episodes. Anyway, here's links: Wikipedia: en.wikipedia.org LPEpower images used in video and some more: www.lpepower.com

So... when testing the latest 2 engines just before sending them to customers, i find it again frustrating to discover how much the performance spread varies. 1600 rpms vs. 1400 rpms... The engines were built side by side, all cylinders and switches modified as good as i possibly can make them, components picked up randomly before put into the engines, yet we still see a 200 rpms difference. :(
This time a small inline engine using the small lego cilynders. It's doing only 2400 rpms, but since it's only 2 cilynders the vibrations are extreme :( I know that those small cilynder engines are capable of much more, but with only 2 cilynders i won't achieve much more (probably). The speed computer is geared down 3:1 for better accuracy.
Engine is built to be the main propulsion unit of a racecar that will be utilised by a Puerto rican university team, in a race!!! Details about that another time. Anyway, engine runs perfect, revs up to 1620rpms and is extremly smooth and responsive. I dare say the most efficient engine that LPEpower has made to date.
In the video it isn't really apparent how fast this 1997 audi a4 was actually going. The squeeking sound comes from crappy s+m tires. THe conversation is mostly about the passanger side CV joint begging for mercy.
Many bugs were discovered during this outing, while you watch this video i have fixed them all. None of the faults seen in this video will happen again. The crash happened, because the steering ball joint got dislocated after the car drove over the garden hose, which sent it into the wall. Video was made and edited by my friend IceBone ( www.flickr.com , www.73634.com )
This is the first episode of the LPEpower show, where we talk about car technology remade in lego. Sorry for the bad lighting and my horrible accent and all the er-s... this episode just wasn't scripted. The next episode will be about suspensions and will be of hopefully much better quality.

Here i am explaining the switch changes in the LPEpower engines and we're right away seing the first run of the i3 with the switches from the pictures. It ran a fine 2100 rpms. The cloud of mist coming out of the engine at the beginning is the silicone spray lubricant that was sprayed into the intake before running it on air for the first time.
Second run after enlarging all inlets and all T pieces. Still not running 1500 rpms as it should. The 2 things i can think of are the worn cylinder rods (customer supplied cylinders) and my compressor putting out "just" 7.5 bars, instead of 8. Other than that, the engine is perfect.
Test for a costumer, engine runs 1860 rpms. I'd prefer it to be higher, but i don't want to spend more time to get 200 rpms more. Engine runs great. Just couldn't show you properly because i was holding phone with one hand and air pistol with the other hand. And the pistol was popping out at full pressure.
