An event that was already immense in scale and significance has now grown even larger. Port Royal Speedway announced Friday night a massive boost to the purse for this weekend's Bob Weikert Memorial for High Limit Racing Sprint Cars. 

Sunday's main event, which was scheduled to pay $75,000 to the winner for a second straight year, will now pay $100,000 to the driver that ends up in victory lane. Additionally, Saturday night's Bob Weikert Memorial Fallen Hero Championship will now pay $20,000-to-win. 

According to a social media post from Port Royal Speedway, the massive purse increase was made possible as a result of "a generous donation."

With the increase to a six-figure payday, the Bob Weikert Memorial becomes just the ninth event on this year's 410 Sprint Car schedule paying $100,000 or more to win. It's also now the fourth race on the High Limit Racing schedule with a six-figure payday and the richest race in Port Royal Speedway history. 

The Bob Weikert Memorial was scheduled to begin Friday night; however, rain showers throughout the afternoon and evening forced event officials to cancel the opening night of racing. Racing is now slated to resume Saturday with a much more favorable weather forecast and a field of nearly 40 Sprint Cars in the pit area.
