ANN ARBOR, MI — Four teams have emerged from fierce competition in the first two rounds of the eighth annual MAHLE Engine Builder Showdown, and are now headed for the semi-finals on May 22.

Presented by MAHLE Clevite Inc., this year’s Showdown saw a record 19 teams enter the competition to build and run a NEXTEL Cup 357-cubic-inch Ford engine in the shortest time.

The MAHLE Engine Builder Showdown is a tiered, four-round competition that highlights the knowledge, skills and most of all, the speed of professional engine builders who assemble special performance engines for NASCAR teams. In each round of the competition, the goal is to build, in the shortest time possible, a complete engine and successfully run it for one minute. All competition is held at NTI.

The first round of the Showdown is a timed elimination round in which each team builds against the clock in order to qualify for the quarter-finals. During the quarter, semi-finals and finals, the qualifying teams face each other in a head-to-head competition with the fastest team advancing to the next round. Rounds one and two of the 2007 competition were held May 1, 2 and 3.

"The MAHLE Clevite Engine Builder Showdown has a become a significant venue for the NASCAR engine builder teams to showcase their talents," says Bill McKnight, who is responsible for brand development at MAHLE Clevite Inc. "This year’s event has attracted more teams, and more rookie teams, than in the past seven years – from several of the engine builder shops that serve NASCAR NEXTEL Cup, Busch and Craftsman Truck series."

In building the Showdown engines, the NASCAR teams use MAHLE Clevite engine parts such as Clevite bearings, Perfect Circle piston rings and Victor Reinz gaskets – all of which are official NASCAR Performance Products.

"The quality of the work we do for NASCAR ultimately determines the design, engineering and quality of our performance engine parts for enthusiasts," said McKnight.
