Over view of the engine block, v8 32valves 4 gears and reverse :) been on the little project for ten months now, runs at about 1000rpm and changes gear at full speed. With out the gear box have had it at 3000rpm for about three mins then the knex actually melted in some places and it seized up, she now gets oiled haha

Step 1: Engine

Timing valves and rods with piston, an a pic of the piston with all 4 valves ( grey cogs)

Step 2: Gearbox

Few piccy of the gear box, this was with out a doubt the hardest part on my project, have done maybe ten diff designs, with and with out a clutch, this one seams to hold to power and speed well bt did want one more gear ;)
<p>it looks very cool. Only if I had all the pieces that makes it.</p>
<p>now we only need a car and we're good to go!</p>
It's not automatic :) it's manual
<p>Sweet! I like the automatic transmission. I'm interested in how it works.</p>
<p>this is looking sweet!</p>
<p>This looks awesome! I'm sure it would be a lot of work to post instructions but I'm sure there are a lot of people that would be very grateful if you did. :)</p>
No it is actually manual, I do plan on uploading a video soon, it doesn't have a clutch, it's just relies on low revs during gear change, I have built a clutch for the previous model but would not work with this model so am redesigning it ATM
<p>I have been waiting to see one of these for a long time, and now it's true. I really dig this engine and transmission!</p>
<p>That looks great! The gears look neat and I like the overall look.</p>
<p>Wow! That's impressive! The gear box is really cool. I'm assuming that by your description that it is an automatic transmission?</p>
