DAVID DONOHUE: MARK'S KID, IROC TESTER

This is reprinted from the Daytona Beach News-Journal:
The International Race of Champions crew is at Daytona International Speedway converting its fleet of oval race cars into road course machines.
“It’s been quite a while since we had to make a right-hand turn with these cars,’’ IROC president Jay Signore said Tuesday.
Fourteen years to be exact.
The IROC racers, which will run Round 3 over Daytona’s 3.56-mile road course on June 29, have a real sportscar feel since their last visit in Speed Weeks in February.
All the cars are now outfitted with headlights, brake lights, windshield wipers and a much larger rear spoiler.
“We’re looking for more downforce and balance,’’ Signore said. “It’s been a while since we raced a road course. We’re not in bad shape as far as handling. The biggest part of this test is to solidify the brake balance on the cars. This test is a little bit of chassis and a lot of brakes.’’
Signore has added road racing specialist David Donohue to his test-driver roster, joining Dave Marcis, Jay Sauter and Jim Sauter.
“There are plenty of areas to pass, with the IROC cars in particular because they are so heavy, the braking areas get longer than what we see with sportscars,’’ Donohue said. “They will be spending more time on the brakes and that will create passing opportunities. It will be a lot of fun to watch.’’
Donohue identified five critical areas of the course where this summer’s IROC race can be won or lost:
1. Finish line
“That’s where you win or lose the race. It’s painfully obvious to anyone inside or outside of racing.’’
2. Chicane
“The chicane on the back straightaway is a key area. You are basically full throttle leaving the chicane to the start-finish line. Since the cars are identical, everyone will accelerate the same way. That makes it important to get a good exit out of the chicane. One of the key passing areas on the whole track is braking into the chicane. The speeds on the straightaway won’t be nearly as high as when these cars run just the oval course. Drafting will play a part, but not be as important because these cars won’t be at full throttle for very long. When you run the oval, your car is flat-out all the time and you’re trying to keep momentum. On the road course, you’re really trying to set up a pass when you are braking. Passing on the straights will be dictated by how you get off the previous corner.’’
3. Turn 6 (where the cars leave the infield course and get back on the banked track in NASCAR Turn 1)
“You need a good exit off Turn 6. If you are running equal in terms of braking into the chicane with another car, this may be where you can get a nose up on him. The problem with Turn 6 is that it’s one lane going into the turn, certainly one lane when you get to the middle of the corner. You might see a lot of action down in Turn 6 as drivers fight for position as they set each other up for the chicane.’’
4. The east and west horseshoe turns
“You have to be really clean in the horseshoe corners. The tendency is to get overambitious because they are slow corners, painfully slow corners. You are used to running at high speeds, not this slow through these turns. You have to avoid getting overanxious and try to get more out of a car than what it has to give you. It’s really easy to spin. You also feel cocky because you are going so slowly. These cars are so heavy that once you get them sliding, it’s really easy to have them slide too much. If you lose a lot of speed, somebody will overtake you or you can spin sideways or backwards and you’re out of the race. You don’t have to stay single-file but if somebody gets under you, you need to use your better judgment and decide whether to run the outside line or just let him go. I think you’ll see a lot of trading places in these areas.”
5. Turn 1
“The last key area of the track will be braking into Turn 1. Turn 1 is a big passing area. Again, it will depend how well you get your car off the chicane on the other side of the track. Depending how you drive out of the chicane will dictate how well you get into Turn 1.’’
