WaMoGu 13B Stud Kit
WaMoGu Engine Stud Kit designed for High Horsepower applications. These studs are available for all 13B engines including the MSP-13B Rx-8 engine. This stud kit is a more linear, and precise medium of torquing the engine compared to stock tension bolts. Torquing the stock bolts creates friction at both the threads, and head of the bolt. This unnecessary friction promotes false torque readings and the result is reduced and uneven clamping force. Instead of twisting a bolt to achieve a desired torque reading, studs are stretched in a static position. Furthermore and more importantly these studs are made from far superior material & manufacturing process which increases clamping force evenly, and limits engine expansion. The OEM bolt material stretches under high boost and in turn, reduces clamping force. An engine using the OEM bolts will expand several thousands, as measured with a strain gauge on an engine dyno. This expansion can damage to the engine's internals. Common harmonic, and resonance issues are reduced due to the superior material used in the stud manufacturing. Installing these studs will reduce engine expansion and movement which is a must for a high powered rotary.
