INDIANAPOLIS, July 17, 2001 - CART and its engine manufacturers Ford, Honda and Toyota reached a mutually agreed solution on July 16 regarding the use of the manifold pressure relief valve extension to regulate the allowable manifold pressure at 36 inched Hg absolute at the superspeedway events (Michigan International Speedway and California Speedway) and 37" for the remaining races of the FedEx Championship Series.

Following deliberate consultation with its engine manufacturers to identify the most suitable option for all parties involved, CART will require Champ Cars to use the 3/4 -inch case extension for the remainder of the season, beginning with the Michigan 500 Presented by Toyota scheduled for July 20 - 22 at MIS. (From CART press release 7/1601).

"It's good news to hear that finally we have managed to put this pop-off valve issue behind us and move on," said owner Derrick Walker. "However it has highlighted some of the procedural issues which have in some respects have distorted our focus on what has really happened here. I also feel pleased that Toyota has received justice and that the extension will now remain on for the rest of the season, as it should. The important thing now is that we reorganize the process and the organization to give CART the ability to police the series effectively in the future."
