NASCAR Dodges running new R6P8 engines

There will be new power in the Penske Dodges when they hit the track for the Goody’s Fast Relief 500 at Martinsville Speedway next Sunday. Both the No. 2 Miller Lite Charger and the No. 22 Shell Pennzoil Charger will be running with SRT Motorsports newly updated R6P8 racing engine.

“We are excited to launch our new “closed deck” engine block with Penske Racing Engines for the Sprint Cup Series at Martinsville this weekend,” said Dave Bailey, SRT Motorsports Engineering. “We are very pleased with the performance and durability of our previous ‘open deck’ block, but are introducing design changes to help improve head gasket life and future capability for power increases. The post machining and processing time at Penske’s engine shop will be significantly reduced. We will also take advantage of weight improvements that come along with the base block material changing to “compacted graphite iron” similar to the other manufacturers. We worked closely with NASCAR to ensure the changes are compliant and have competitive parity.”
