From IMSA
Ahead of this weekend's Tudor United SportsCar Championship round at Laguna Seca Raceway, California, IMSA has announced that teams running the Daytona Prototype (DP) cars of Class P will all face a reduction in horsepower.
With Class P allowing the use of DPs, P2 and Deltawing cars, IMSA officials are continuing to strive for an equitable balance of performance between them.
With the first three races of the season being won by DP cars, some critics have been particularly Daytona vocal at the results.
As a result, the IMSA has announced that the Chevrolet Corvette DPs will now run with a one-millimeter smaller air restrictor to help stunt performance. Ford EcoBoost powered DPs will also run with a smaller restrictor, this time of 0.9mm reduction, in combination with a reduction in boost pressure.
The upshot of these revisions is a reduction of around 10 to 14 horsepower for the DP cars.
“We do have the lap times between DPs and P2s very close now,” explained Scot Elkins, vice president of competition and technical regulations, IMSA.
“To be making relatively small adjustments at this stage is something we feel good about. There is so much involved with winning a race. And there's only so much we can have an effect on [with regulations].”
