Details

The Sparks Racing Stage 3 Cylinder Head Porting services for the Polaris RZR 1000 XP are second to none. This is a must for any serious performance build or any big bore engine. Engine performance is based around the principals of air flow, which we maximize in our porting profiles.  An engine’s ability to make power is directly related to the engine’s ability to supply and exhaust enough air to meet the demands of the engine. On the RZR 1000 XP in particular, there is a significant imbalance between the intake valve diameter and exhaust valve diameter. So, in our Stage 3 cylinder head work we increase the exhaust valve diameter by 3.2mm which creates an ideal balance in valve diameters. We have been designing and building industry leading cylinder head profiles for over 40 years, so we are no stranger to cylinder head flow dynamics and performance characteristics. We have done extensive R&D on both our state-of-the-art flow bench and chassis dyno to refine our porting designs and ensure the most performance possible out of each cylinder head we build. All the cylinder heads we build are backed by over 4 decades of championship winning performance and are still building championships today!
