Which Royal Purple? They make a complete line you know. Generally the racing R.P.'s do make for a bit more power, but I wonder out loud if they really arn't designed for engines that see rebuilds after a race, not streetcars. Right now, considering costs,availability,and other factors it's tough to look past Mobil 1 for streetcars and mild racecar builds in my opinion. Just a opinion though.
