In order to rotate a crankshaft smoothly, the accuracy (The degree of a true circle, and surface roughness) of a pin journal becomes important.
The crankshaft which polish finished pays careful attention to the degree of a true circle, the surface roughness, and transformation etc... and is wrapped.
After a finishing surface treatment, it is wrapped and a friction loss is made into the minimum. Even if it is the weight form in which the rate of balance is excellent however, when the balance of the whole crankshaft is bad or bent, vibration occurs. Dynamic balance adjustment and bend correction were performed and the cause of vibration as much as possible is eliminated.

TODA Racing offers a stroker kit for the B16A engine which increases displacement to 1797cc. The stroke is increased from 77.4mm to 87.2mm. The kit comes with TODA forged pistons (81mm or 81.5mm), heavy duty piston wrist pins, fully balanced connection rods, dynamically balanced crankshaft, and connecting rod bearings which already have the clearance set. Compression ratio with a stock head gasket is 11.0 : 1 and the rod ratio is 1.54. This kit is completely balanced and blue printed
It is got larger effect to have arranged weight in the position which is distant from a rotational center (journal center)
ReplyDeleteTherefore, the superfluous flesh near a rotational center as much as possible is remove
