So Castrol in RSA have put forth a challenge to Royal Purple. They are convinced that Royal Purple will not give a power increase from a dyno run. So the minimum increase must be 1% changing from Castrol to RP. So the vehicle they doing the test on is a 240KW (0n the wheels) Cosworth. Castrol are putting in RS in the engine, SMX in the gearbox and EP 90 in Diff. Royal Purple is putting Racing 21 in the engine, Syncromax in the gearbox and Max-Gear in the Diff. Any thoughts of what you think the outcome is gonna be??
