Wallace Team Downplays Engine Flap

Article excerpt

The term "close enough" was used Tuesday to explain why the Penske South team wasn't penalized for the oversized engine that won Sunday's stock-car race in Richmond, Va.

Instead of using a 14-to-1 compression-ratio engine, Rusty Wallace used a 14.011-to-1 to win the Pontiac 400. That, according to Winston Cup spokesman Kevin Triplett, is close enough.

"It wasn't 14.1 or 14.2," he said. "When you get below tenths, like in this case, it doesn't make that much difference. We're satisfied the engine was in compliance." Compression ratio relates to the volume of air compressed in a combustion chamber when the piston reaches the top of its upstroke. The more tightly the air is compressed, the higher the ratio. The higher the ratio, the greater the horsepower reading and the faster the car. After unlimited compression at most tracks last year, Cup cars must run at 14-to-1 this year. NASCAR would not disclose the compression ratio of Wallace's engine during its Sunday night test. Triplett said it was checked more than once and that it exceeded specs each time. Don Miller, manager of the Roger Penske-owned team, said the engine went to Richmond at 13.72-to-1. He blamed the discrepancy on the buildup of carbon deposits within the cylinder during the 400-lap race. "Mike Ege, who builds all our engines, had it right at the edge," Miller said. "This sport has become so competitive you can't leave anything on the table. But, at the same time, we'd never build one we know would fail inspection. "We have no control over the carbon buildup, and neither does NASCAR. Rusty did a long cooldown lap at idle speed, and that might have helped push it up from 13.72-to-1. We'll recertify every one of our engines before we take them to a track." Engine-builders routinely factor in carbon buildup when preparing for a race. Craig Griffitts of the Bill Davis-owned team aims for a pre-race reading of 13. …
