Cadillac’s dominant DPi restricted ahead of Daytona 24

19 January 2018

Ahead of the Rolex 24 at Daytona, the Cadillac Dpi-V.R has had its airflow restricted following a dominant performance at the first pre-race test, the Roar Before the 24.

The Cadillac’s normally-aspirated 5.5 litre V8 has had its restrictors reduced in diameter by 0.6 mm to 31.6 mm in the pre-event round of balance of performance changes. The changes were somewhat expected after a Cadillac went fastest in every one of the sessions over the three-day test, and headed up the top four positions in the combined times. The cars were however compensated by being allowed a one-litre larger fuel capacity as well as a larger refuelling restrictor.

The Cadillac isn’t the only racer that has had changes mandated ahead of the first round of the IMSA WeatherTech SportsCar Championship. Tequila Patron ESM’s Nissan Onroak DPis have been given a power boost in the mid-to-high rev ranges, while Mazda Team Joest’s  MTRT24-Ps have had a slight reduction in turbo boost pressures. However  the car has also been allowed a 15-kilogramme weight reduction.

Elsewhere, in the GTLM class, the new BMW M8 GTE which struggled at the Roar has been allowed a boost increase and a 10 kg minimum weight decrease, bringing the car down to 1240 kg. The M8 has also had its refuelling restrictor and tank capacity increased. Its rivals in the class meanwhile, the Corvette C7.R and Ford GT have both had their minimum rear wing angles adjusted.

In the GT Daytona cars, the Acura NSX GT3 has had its weight put up by 10 kg while the Mercedes AMG GT3 has been relieved of 15 kg. The Audi R8 LMS and Lamborghini Huracan have had had their air restrictors reduced by -1.0mm, while the BMW M6 GT3 has been allowed an increase in boost.

The results of the changes will be seen when the Daytona 24 Hours, the IMSA SportsCar opener gets underway on the 27th of January.
