Don't do it! it's a rabbit in disguise and it will only lead you to its hole. Imagine miso soup. The wiring will smell like miso soup and be as useless. Seen others (not Scotty) try and give up. If you are doing it for the entainment/curiosity value set a budget.

2024-11-07 18:58:40 +0000 UTCI have no idea what I'm talking about but I think you're dead on with the pistons. Because the forces cancel from the pistons themselves there wouldn't even be a responsiveness benefit, except that you could use lighter counterweights on the crank. The main reason to lighten rods and pistons is because of the huge accelerations they undergo if you're revving to high RPMs. You'd know better than me but I think some diesels even use steel pistons, which I can't imagine you'd do if there was a power penalty to their weight.

2024-10-22 03:17:18 +0000 UTCOn the piston weight - I worked in a speed shop for a few years, a good time ago. Built some pretty quick engines. What a lighter rotating assembly gets you is a 'snappier' engine, with quicker throttle response that is predominantly noticeable when revving the engine at no/low load. There seems to be a very slight increase in power, mostly due to friction differences, but that's pretty hard to quantify as we never built an engine with pistons that were identical in dimension, but differed in weight. It might be worthwhile if the goal is a very high RPM engine, but maybe not worth it for anything at a steady state RPM and/or low RPM situation. There would be additional valvetrain changes needed for high RPM purposes, as well.

2024-10-21 20:05:28 +0000 UTCI reckon you're on the money with the lighter piston Wes - any potential increase in power would be coming from revs, not torque. No overall change to torque, but quicker to increase and decrease revs and potentially higher rev limit. I wonder if it'd have the same reduction in smoothness and stall resistance that a lighter flywheel confers or not?

2024-10-20 21:40:17 +0000 UTCLighter pistons will make more power. A piston is not a rotating mass, it is a linear slide. Accelerating and decelerating a sliding piston consumes energy. The lighter it is, the less energy consumed. The connecting rods are more complicated, as one end is rotating, and one end is sliding with the piston. A lighter connecting rod will still technically make more power, but the effects will be less pronounced.

2024-10-20 19:26:02 +0000 UTCYou ad me, both, like as not, even with a couple decades difference in the "when" of it. In my case, a 1978 Mercury Bobcat of all things. Got me through Grad School, too.
CapnMac82
2024-10-20 16:58:06 +0000 UTCOn the piston mass question, I think you are correct, as long-skirted cylinders are used on scavenging-cycles engines to no detriment to their power.

2024-10-20 16:55:38 +0000 UTCOn the piston its 6 of 1 and half a dozen of another. My truck has small pistons and runs very well but a lot more goes into that than just pistons.

2024-10-20 13:55:09 +0000 UTCAt least you could move it with the temporary tank and pump. Just imagine the length/size of jumper cables you'd need to move one of the "wonderful" all electric cars that will be the only option for student hand-me-downs once "evil" emissions creating engines are banned! ;-)

2024-10-20 07:23:18 +0000 UTCMy dad sold me his 1974 Dodge Dart Se with a 318, rear quarter panels rusted out and a mere 450k miles on it for $150. I ran that beast for another 150k and sold it for $150 to a man who put a complete front end into it and brazed in new metal for the rear end. He ran it for another ~200 miles before it was T-boned and ffinally totalled out. The engine, and transmission still ran fine. But ~800k miles on a mid 70's car is pretty hard to understand. The reason it was able to do it was that it was given an aftermarket rust-prorust-prooffing treatment that injected tar into every possible orifice (including some that had to have holes drilled and plugged) right from the dealers lot. It never rusted anywhere except the rear quarter panels. Those rusted because of a rear end accident. But would I let my college daughter drive that? Not just no, but @#$% no! Light piston/crank will not give more power, or a better power curve. It will theoretically, give you more fuel efficiency because you're not having to move as much weight. My '03 F350 uses a TON more diesel (8-14mpg) than my '17 Mirage G4 (40-60mpg). The F350 weighs >8700#, the Mirage comes in at ~2100#. The G4 I've nicknamed "Juicebox" because that what I'll look like if I tangle with an angry 80k tractor trailer doing Mach 2 when I'm trying to maintain 60mph.

2024-10-20 00:09:57 +0000 UTCI had 20 pounds in my tires. I added 5 more, to make it 25 pounds. Now my car goes faster! Clearly, more pounds equals faster. Does that work with kilograms? :-))))
Terry Lawrence
2024-10-19 21:33:33 +0000 UTCFWIW I agree with your analysis - lighter reciprocating mass improves responsiveness, it doesn't add HP except indirectly by allowing a higher redline without everything coming apart.

2024-10-19 20:22:14 +0000 UTCI think you're probably right. The push and pull are going to cancel, I would think.

2024-10-19 20:07:40 +0000 UTCHe's not changing the piston diameter or stroke. I think if you just reduce the weight and nothing else, it doesn't help with power.

2024-10-19 19:51:34 +0000 UTCI am by no means an engineer, but wouldn't torque be determined by piston size and composition in addition to weight?

2024-10-19 19:14:40 +0000 UTCSince my 1st comment was based on the 1st minute, I’m gonna add another to prove I watched the entire vid. Bigger is mostly ‘more’ power wise. I’m simple so I figure a 250 man is gonna be more powerful than a 125 pounder. The 125 guy will get faster, sooner but will never achieve the power. Also, Red Pandas are endangered so be careful with yours

2024-10-19 17:14:47 +0000 UTCI've never worked on one of these but I can tell by what's going on under the hood it must be great fun, I did know a lady who owned one and she did not maintain it at all, I'm talking never got plugs, never got an oil change, it got absolutely nothing she just drove the pants off it and HARD, to its credit it seemed to take the abuse very well, until inevitably one day it didn't but it did seem to take a surprisingly long time to die, I remember she would start it in the morning and it sounded like an old WW2 airplane engine trying to start, and boy did that thing smoke! Almost as much as that lady did!

2024-10-19 17:11:01 +0000 UTCWes, I agree with your analysis. HP=(torque x rpm)/k. If lighter pistons allow higher rpm, they also limit torque, so the net is zero.

2024-10-19 17:04:02 +0000 UTCReminds me when I worked on an old Polaris 440 quad that I found in a garage on a property I care taking. The parts were scattered hither and yan and I could not locate the throttle/carburetor (turns out the son of the owner absconded with it after his dad crashed it for fear he would ride it again, which was okay because the carb was jeb welded together). After putting it all together with some new/used parts (including a new cam as the exhaust lobe was worn to nothing), it actually came to life and ran very well (I used it for farm duties until I eventually moved on).

Greg Quante
2024-10-19 16:05:10 +0000 UTClook at pistons from f1 engines vs drag race engine pistons. I agree with your hypothesis that the lighter pistons would result in more responsive engine, nut i doubt it would result in more power except for higher redline due to less reciprocating mass

Chris Freemesser
2024-10-19 15:37:53 +0000 UTCFrom what I understand, to get more power out of an internal combustion engine (ICE) you'd need to improve the thermal efficiency of the engine. Getting a lighter piston just changes the power curve of the engine. You're only going to get so much work from converting chemical to mechanical energy. And that conversion isn't all that efficient to begin with. Think about steam engines, they can only go so fast because their driving links weigh a few tons. If you try to drive them too fast, you would overcome the mechanical strength of the material and it would fail.
Marco Lopes
2024-10-19 15:33:51 +0000 UTCI think you nailed it, a lightweight rotating assembly allows for higher piston velocities before you cause a force greater than the rod can arrest when the piston changes direction, this is also the idea behind a short stroke over square engine, you get lower peak piston velocities meaning you can achieve higher RPMs before you cause a force greater than the rod can handle.
