With Grand-Am Rolex Series testing having kicked off at Daytona, Krohn Racing has revealed that it will go back to Ford engines for the 2009 season.

On the opening day of the test, the team revealed it will return to Ford power next year - the same engines it ran in 2006 when Jorg Bergmeister secured the Daytona Prototype title.

Nic Jonsson tested the lime green #75 Ford Lola on Monday, and is expected to be joined by Tracy Krohn and Ricardo Zonta on Tuesday. Jonsson and Zonta finished eighth in the 2008 Daytona Prototype championship, co-driving the #76 Krohn Racing Pontiac Lola.

"The decision to run Ford was made a couple of weeks ago, to go with a different powerplant for the '09 season, switching from Pontiac to Ford," Jonsson said. "I think we saw last year that the Ford powerplant was strong. We definitely struggled last year, not just with the car, but with the powerplant.

"We've done everything we can on our part to get the best engine at the back of our ProtoAuto Lola, and now it's up to us to get the car fine-tuned to where we can win some races next year and run for the championship."

While the 2008 season was spent developing the Lola chassis - after running the Riley in the Rolex 24 at the start of the year - Jonsson added that he didn't expect the engine switch to pose a problem.

"This year was spent learning the ProtoAuto Lola chassis," he said. "I think we've made a lot of progress with the Lola chassis. We still have some to come. But I think the engine is a sorted item.

"John Maddox with Roush Yates Engines is doing a great job with that powerplant. We ran the powerplant in '06 when we won the championship the first year out with Krohn Racing, and I think it's going to prove itself to be the best and the right choice for us to go with."
