j JUST THE FACTS Blue Streak VVT Sprocket Comparison Analysis Superior Quality SMP engineers have designed numerous improvements into our most popular VVT Sprocket for enhanced performance and long lasting durability Larger contact area no friction between sprocket and rotor Design improvements virtually eliminate component wear less oil loss Advanced coil spring and locking pin Better performance in timing phase response Overall a better performing and longer lasting VVT Sprocket Trigger Wheel Angle Comparison The angle between timing mark and trigger wheel Manufacturer Angle Difference OE Ford 3R2Z6A257DA 2 16 Blue Streak VVT500 2 08 0 08 Competitor D Improved 1 97 0 19 Source SMP Testing Lab 2020 Analysis The Blue Streak VVT sprocket trigger wheel angle is a close match to the OE ensuring proper alignment and operation Competitor D s improved sprocket is significantly smaller than the OEM which may cause improper alignment and signal deviation leading to faulty operation CD CD JUST THE FACTS Sprocket Over Pin Diameter Comparison Sprocket Over Pin Diameter comparison Manufacturer OPD mm Difference mm OE Ford 3R2Z6A257DA 132 12 Blue Streak VVT500 132 14 0 02 Competitor D Improved 132 35 0 23 Source SMP Testing Lab 2020 Analysis The Blue Streak VVT sprocket s Over Pin Diameter OPD is virtually identical to the original ensuring proper fit and performance Competitor D s improved sprocket has a significantly larger OPD than the OEM which may create multiple issues including the stretching of the timing chain that will result in potential cylinder and engine damage Oil Loss Comparison Manufacturer Oil Loss Difference OE Ford 3R2Z6A257DA 0 10L min Blue Streak VVT500 0 10L min 0 00 Competitor D Improved 0 21L min 0 11L min Analysis Blue Streak matches the original for oil loss tolerance Competitor D s clearance is greater than the original which may result in oil seepage a drop in pressure excessive wear and premature failure Source SMP Testing Lab 2020 Blue Streak LIMITED LIFETIME WARRANTY We are so confdent in the durability of our Blue Streak by Standard products that we ve backed every part with our Limited Lifetime Warranty Competitor D Improved R chamfer on signal driven area No R chamfer on signal driven area Blue Streak OE No R chamfer on signal driven area CD CD Locking pin in and out clearance in pin base JUST THE FACTS Signal Driven Area of Trigger Wheel Comparison Source SMP Testing Lab 2020 Analysis The OE and Blue Streak have no R chamfer on the signal driven area of the trigger wheel while Competitor D s uses an R chamfer design Competitor D s rounded edge may affect the timing signal as the leading edge goes in slower and the trailing edge comes out faster making it more difficult for their sprocket to receive the proper vertical signal Locking Pin In and Out Clearance Comparison Manufacturer Locking Pin In Out Clearance Difference OE Ford 3R2Z6A257DA 0 55 Blue Streak VVT500 0 55 0 00 Competitor D Improved 1 04 0 49 Source SMP Testing Lab 2020 Analysis Blue Streak matches the original locking pin clearance Competitor D s clearance is significantly larger than the original which may create an improper ft that results in their locking pin rattling and jiggling after installation OE Metal paddle Blue Streak Larger contact area with no paddle CD MP ard Motor Products Inc JUST THE FACTS Blue Streak Design Improvements Over the Original Analysis Blue Streak has improved on the original using all metal in an integrated machined design The Blue Streak sprocket does not use paddle inserts and our integrated design provides a larger contact area improving overall wear as well as maintaining proper lubrication and gap Less friction means our VVT sprocket responds fast at lower pressure delivering better performance in the timing phase peak operation and a long service life The OE design uses inserted metal paddles that may produce iron shavings during use eventually impeding performance and shortening sprocket wear Competitor D s improved design has a chamfered slot and uses plastic paddle inserts that wear easily and may not hold up under normal operation Competitor D Plastic paddle Source SMP Testing Lab 2020 Conclusion Blue Streak matches the original in all key tolerances and improves on the OE unit with advanced engineering for an enhanced sprocket design Competitor D s improved part which was developed to overcome their initial part s flaws still falls short in design performance and durability The Blue Streak sprocket is superior to the competition delivering a more durable better performing and longer lasting VVT sprocket StandardBlueStreak com BS10235VVTSA
