========================================================================== GSC Power Division has announced their new line of Billet Camshafts which are constructed of cold-forged alloy steel for extreme strength and reliability! These billet camshafts will be superseding their cast line of camshafts as the new billet versions are available. The key features and benefits of these new Billet Camshafts are outlined below. ==========================================================================
GSC Power-Division is known for its superior camshafts with strong performance and sustainable drivability. With the introduction of the new billet cores, they now offer a true performance upgraded camshaft with advancements exceeding lobe profile re-designs.
It’s important to remember that when the OEM companies design a cast material camshaft, they are not designing the camshaft for the vibration and stress levels to run at 2 to 3 times higher than OEM horsepower levels. When upgrading an engine to this level of performance, the need for a stronger core is highly recommended in order for our customers to have reliable long-term performance from their camshaft.
1) - Billet Cores GSC's 7000 series billet cams start off as cold-forged alloy steel bars. This means the steel is pressed into its round bar shape rather than molten steel being poured into a mold, as in cast steel cores. The benefit is that the material is both stronger and more dense, leaving no room for pores or imperfections during the forming of the core. These new cores set the base for a stronger building block in their advanced camshaft development and design process. Furthermore, on high torsion and shock load camshafts with variable valve timing, the billet cores will provide an extremely high level of reliability over the cast core camshafts. These applications include the Mitsubishi Evolution 9 & 10, Subaru EJ257 & 207, as well as many others. Shear stresses at all undercuts for oil routing journals are met by the stronger cross- sectional area of the billet core vs. the cast core. Shearing at any of these points in variable valve timing equipped engines is now highly unlikely. The fully turned, ground, billet camshafts are also extremely balanced in order to minimize and/or eliminate all types of added harmonics and vibrations.
2) - Nitride Coating This treatment process offers GSC's new billet camshafts a protective layer and case hardened shell to help aid in strength as well as lobe surface lubrication. This is extremely important for flat tappet style engines (IE Subaru EJ, Mitsubishi 4b11, Toyota 2JZ, etc). This nitrided layer also adds greater protection for break-in and long-term surface durability.
GSC Power Division has instituted this coating across the entire product line with extreme attention to the Subaru EJ motor due to its horizontal design and the tough oiling conditions inside of the heads to the camshafts and translating tappets. GSC Power-Division is excited to see the new, higher standard of expectation these camshafts will take to the aftermarket.
