DAYTONA BEACH, Fla. (November 18, 2002) -- Grand American Road Racing Association has announced final approval and specifications for the Toyota Racing Development (TRD) 4.3 liter V8 engine for use in Daytona Prototypes.
The TRD engine was tested at Pro-Motion Engineering in Charlotte, N.C., last month with Grand American and TRD representatives in attendance. All engines approved for competition in the Daytona Prototypes class must undergo testing at PME.
"We want to involve as many manufacturers as we can in this new class," Daytona Prototypes Project Manager Mark Raffauf explained. "By testing the engines in advance, we can determine which components and specifications will be right to put the engine in the power range we want to have."
Based on results and analysis from the test, the TRD engine is being allowed a maximum engine RPM of 8200 and a maximum compression ratio of 11:1. Additionally the engine will have a maximum valve lift of .470-inch. The approval also includes specifications for the throttle body and engine management system.
"The TRD engine is really solid," Raffauf continued. "At this level of tuning, it should be very reliable and cost-effective to maintain."
"We are very pleased at the response we have received from chassis builders and prospective race teams since announcing our intent to submit the Toyota V8 engine for Daytona Prototype certification," Gary Reed, Sr. Manager for TRD Special Projects said. "Why? Because we offer a complete package - a competitive engine at a competitive price, TRD track support at all twelve events and a generous contingency plan for those who want to partner with Toyota in our return to professional North American sports car racing."
Several car builders have already announced plans to build cars using the TRD engine including Riley & Scott, FABCAR and Doran Racing.
