To figure out an engine's rod ratio (aka rod-to-stroke ratio), divide connecting rod length (that is, the distance from the center of the big and small ends, aka center to ... WebNov 5, 2010 · This year's redlines at 13,750, and makes its peak power 2000rpm further up the scale. At that 13,750rpm redline, the R1's average piston speed over the 53.6mm stroke is 24.6m/s - that's just over 55mph in English. By way of comparison, the longer-stroke GSX-R1000 (bore 73mm, stroke 59mm), redlines at a lowly 12,250rpm, at which point …

WebFeb 26, 2024 · I see 1.125 to 1.13 as a very good balance. For instance, if you had a 4.16 bore and 3. 68 3.7 stroke, it would be a 400 ci with the same ratio of a 4.25 427. If the rods are 6.85 long with 1.4 some cr pistons with low friction rings the rod ratio would be like a 352 or 360 with stock rods but too tall of a piston. WebApr 20, 2024 · Compression Ratio = (Swept Volume + Clearance Volume) / Clearance Volume. Swept Volume = (Cylinder Diameter / 2) Squared x 3.14 x Stroke.
