Autosport Development Portland Pre-Race Report
Hayner and MacDonald Take Advantage of Promoter’s Test Day

Portland, Ore. July 28 The Autosport Development team returns to the  
West Coast this weekend for Round 8 of the SCCA Pro SPEED World  
Challenge GT race at Portland International Raceway in Portland,  
Oregon. Hoping for cooler temperatures than the 100+ degrees  
experienced last year, the team likes their chances.

After today’s practice sessions, both Hayner and the team were very  
confident.

“Last year we had our best finish of the season at this track,”  
remarked Crew Chief, Rob Wanamaker, referring to their 11th place  
finish in 2004. “Granted, our 2005 cars are brand new and something  
of a different beast, but we like our chances on this track.”

Stu Hayner agreed. “We have a lot of confidence in the new cars now,”  
said Stu. “While last year’s set-up sheets aren’t applicable, we do  
know what we weren’t able to do and what we can do now to affect the  
handling. Trust me, the #5 GMAC Commercial Finance / Trenton Forging  
GTO is very capable of running up front and mixing it up. We’re not  
going to be bashful. This is a momentum track and I think it suits my  
style. We’re setting up to go to the front.”

Joining Stu this weekend and driving the #7 Autosport Development GTO  
is Steve MacDonald of Woodinville, Washington.

“I’m looking forward to working with Stu and the entire Autosport  
Development team,” said MacDonald. “They run a great program and the  
car is really well prepared. This is something I’ve looked forward to  
doing and I think Stu and the team are a great fit for me. These guys  
have made me feel right at home. Hopefully, it will be a good weekend  
for us all.”

Jim Osborn and Chili Pepper Racing for Remote Area Medical are slated  
to return to the #7 GTO for round 9 in Denver, August 12-14.

The Portland Grand Prix is being held in conjunction with the  
American Le Mans Series race that will run Saturday, July 30 live on  
SPEED Channel at 8pm EDT. The SPEED World Challenge GT race will run  
on Sunday, July 31 at 2:25pm PDT and will air Sunday August 7th at  
3pm EDT on SPEED. The Touring Car race will run on Saturday at 1:00pm  
PDT and air the following day on SPEED at 3pm EDT.
