In this episode, Papa Suppy explains what Bore, Stroke, and Honing is. How it works. What role it plays. Sit back, and learn something.
Yep, you can win this motor once it’s built! Check out www.hoonigan.com/giveaway

Say whaaaaaaat we’re building a sick 10,000rpm N/A K series, we’re giving you the chance to win it, AND Suppy is going to teach you stuff about engines along the way? Maybe we’re generous like that. Sometimes. Or maybe the pain of not seeing Zac’s truck around anymore will make us think twice. Either way, let us know what you would want to swap this thing into.

Ooh I actually know something here. Re. the torque vs. angle. The important force here is clamping strength but that's pretty damn hard to directly measure so the best way is to calculate it using the ramp angle on the bolt thread, this directly translates to an angle that can be measured. Torque on the other hand can vary a bit based on things like putting oil on before tightening so you have to know if they meant dry or lubed torque readings. Amount of angle doesn't change based on the turning force required. Thanks AvE

Reasonable 101, except for a few glaring mistakes... Normally I'd let them pass, but from the comments it seems there are quite a few people who are using this as a learning tool. 0.010" is ~0.25mm 😉 5:55 - uh, no, that is the crankshaft 'throw' the stoke is double that distance - the difference between opposite throws in this case. 2 bolt main bearing caps are found on almost all engines with 4, or even 6, normally being restricted to high performance engines where the additional clamping strength is requred - girle comments are good, though. WAY too much sealant for the girdle - the gap it's sealing is barely in the thou' range - almost all that excess sealant is going to be extruded to the inside of the engine, in the crankcase - it will often breake free and more than one engine has failed because the stuff has bloked the pickups and caused a loss of oil pressure. A warning to builders looking to save money - ANY bolt that has an angle specified to tighten-to is a 'stretch to yield' fastener and MUST(!) always be replaced with a new fastener - NO exceptions! However, enphasising the importance of the engine being CLEAN kinda makes up for that. 😎

2:25 that's not the reason for honing. Honing is done for the oil to 'grab by' the cylinder walls, and thus create a lubrication 'film' (or surface, if you will). That would, on contrary of what Suppy said, make your pistons travel smoother without grabbing the cylinder walls. Also it prolongs the life of your rings, pistons, and block. It has nothing to do with compression.

not sure if part of the video is skipped, but did Suppy install the bearings without doing the clearance first? Not sure if its OEM bearings or aftermarket, OEM bearings have a certain thickness which helps make the crank more balanced. (some say OEM bearings are more accurate than aftermarket ones) Usually the steps involve using plastigauge and stuff but I'm assuming Suppy knows what he is doing. ✌️

@3:18 - not knocking you Suppy but you CAN add weight to a crank to balance it... usually more expensive to do as it requires a very heavy metal like Mallory to be pressed in a hole. The OEs find it cheaper to cast larger throws and just drill to lighten / balance. Awesome video

I'm sorry to say Suppy got the honing bit wrong. The rings are pushed against the wall by the crankcase pressure, coming through small holes in the piston, behind the rings. The cross hatch allows oil to stay on the cylinder wall, so the rings don't scrape on bare metal. A rough surface would wear them down faster, but a cross hatch is a very fine pattern that doesn't scratch.
