Well, where do you think I get my gas port data from, brother? Calculating bore size for an engine. That's how I come up with all that shiit, in the first place. First is what works, second is calculating bore size on what works - it's just a smaller bore, in a gas port - but the math is the same. If the dwell time is the same, and gas block diameter increases, then it's like calculating a stroker engine. Literally. Bore x Bore x Stroke x 0.7854. Done. If you want the same size "engine" in a gas port, but the gas block diameter increased, that's a longer "stroke" if you were building an engine. You need to make the "cylinder" smaller, which would be the gas port in this case. To have the "same size engine" - and keep the same gas pressure... It's all math. Eugene Stoner figured out the physics on it - just apply his physics (and math) of the operations that really work, modify the math for the different shiit, and your gun runs.

So be it, who gives a rat's ass about a circle vs a square? how about a more simple formula as to how to figure displacement ? I'm listening.........

Sharpshooter Posted January 7, 2021 Report Share Posted January 7, 2021 Pi x r squared x stroke. And don't give me any guff about pi being round, not square! 🤪 Quote Link to comment Share on other sites More sharing options...

Maybe because you have to determine the area that a certain size circle actually is, before you can add the depth to that (the stroke), so you can come up with the cylinder volume... Bore x Bore x Stroke x 0.7854 is about as easy as it can get, Mack. It doesn't get any simpler than that... I was explaining the WHY on using the 0.7854, Nuggin'...

(must be the new math way of figureing how to calculate the volume of a cylinder. Exactly. I can post up the paper I wrote on it years ago, if you'd like. It's definitely not a "new math was of figuring it out" either - it's one of the oldest, proven ways around. Quote Link to comment Share on other sites More sharing options...
mrmackc Posted January 8, 2021 Report Share Posted January 8, 2021 I can see where it is convenient when the bore and stroke would be an odd number like 3.675 and the stroke could also be an odd number like 4.279 when using a calculator.

DNP Posted January 8, 2021 Report Share Posted January 8, 2021 (edited) (3.675/2)^2 x 3.141592 x 4.279. Math is math. Edited January 8, 2021 by DNP My dyslexia screwed up pi Quote Link to comment Share on other sites More sharing options...
DNP Posted January 8, 2021 Report Share Posted January 8, 2021 It jut happens to be that the area of a circle tangent to all sides of a square is 78.54% of that square. (I haven’t checked the number for 98’s math, but I trust it) Quote Link to comment Share on other sites More sharing options...
DNP Posted January 8, 2021 Report Share Posted January 8, 2021 (edited) Ok I checked. It’s 78.5398%. I’ll give him the rounding. Edited January 8, 2021 by DNP Quote Link to comment Share on other sites More sharing options...

98Z5V Posted January 30, 2021 Author Report Share Posted January 30, 2021 (edited) Next trip, according to a phonecall from @AZMan tonight, the dates are 19~21 Feb. Friday to Sunday. Sand Time again. If I can't get the 250R engine done by then, I'll take the LTR. I like jumping that thing WAY MORE BETTER anyway. I'll huck that fucker off anything you guys point at... @DNP - Sand. 19~21 Feb, brother. Grab a bike. @SmoothAction - get a flight, brother... Dan has ALOT of guys coming, I'll wrangle the local guys into this one, too, and get a good big trip out of this one. Replacing all the coolant lines on one guy's rig tomorrow.
