dyno results from s&s cycle this dyno chart shows the increase in power and torque that the s&s 106 stroker hot set up kitŪ delivers over a stock 92 [or 100 engine the 106 test engine was equipped with victory stage i mufflers dyno results from dyno jetŪ 200 chassis dynamometer at s&s cycle s research and development facility in viola wisconsin what s in an s&sŪ stroker hot set up kitŪ stroker crankshaft the heart of any s&s stroker kit is a stroker crankshaft as the name implies the stroker crankshaft increases the stroke of the engine the longer stroke makes the piston travel farther in the cylinder increasing the engine s displacement that means that the pistons draw in more air and fuel on each intake stroke it just makes sense that if you can burn more fuel you can make more power but there s more to it than that stroker cranks differ from stock cranks in that the crank journal that the rods ride on is farther from the center of the crankshaft the added distance from the center of the crank shaft gives the pistons and connecting rods more leverage to turn the crank that s why an engine with a longer stroke will generally have more torque than a short stroke motor of equal displacement the s&s crank for the 106 stroker is machined from a 4140 steel forging and increases the stroke of the engine from 102mm to 108mm to complete the crankshaft assembly the kit includes s&s 4340 forged steel connecting rods s&s stroker crankshafts are available for models with roller cam chain 2003-2005 except hammer and touring cruiser and for models with the silent cam chain 2005 hammer and all 2006 models hot set up kits are not available for touring cruiser intake the s&s stroker hot set up kit includes a great looking polished billet aluminum air cleaner assembly with a high flow air filter by making more air available to the engine the s&s air cleaner is an important component in the performance of the hot set up kit this air cleaner is also available separately to increase the performance of stock displacement victory engines see page 5 for more information fuel injection calibration file the stock victory fuel injection system can easily accommodate the fuel delivery needs of the s&s 106 stroker it has plenty of capacity it just needs to be tuned to provide the correct amount of fuel to take advantage of the cams exhaust and the increased displacement an authorization code is included with each kit which allows your victory technician to load an s&s calibration file into the memory of the stock fuel injection module it is important to note that the calibration files available are customized for use with the parts included with the stroker kit and the with the recommended exhaust system if other components are used decreased performance and possible engine damage may result valve train to make the most of the increased displacement of the 106 s&s stroker engine s&s includes a set of special s&s .495 lift cam shafts and a set of s&s high lift valve springs with top collars and valve keepers the increased lift and optimized timing of the cams increases the amount of air the engine can draw in and allows the engine to get rid of exhaust gasses more efficiently the valve springs accommodate the increased lift of the cams and assure accurate valve train operation at high rpm 3
