New engines for Penske: There will be new power in the Penske Dodges when they hit the track for the Goody's Fast Relief 500 at Martinsville Speedway on Sunday. Both the #2 Miller Lite Charger (Brad Keselowski) and the #22 Shell Pennzoil Charger (A.J. Allmendinger) 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."(Allpar.com)(3-30-2012)
 
I was not aware that they were using open deck blocks, I don't understand why they would. Then again, they weren't experiencing a lot of engine failures.
 
I wonder if I could get one of those to replace the 4.7 in my Dakota? Fuel mileage probably wouldn't be all that different ;)

I would guess that this "The post machining and processing time at Penske's engine shop will be significantly reduced. " part of the article is refering to Penske'S engine/machine shop having to weld up the cylinder block deckS and remachine them.

The 4.7 is the best dakota motor actually. Most of the 4.7's on DF get about 19. I only get 14 with my V6.

I have no problem with the 4.7 but would have to drive like a old lady on her way to church to achieve 19 mpg. It's also a 4X4 and I do most of my driving around town - not that I drive around with 4X4 engaged :eek:
 
Thanks for the link.

On topic: the new Penske engine performed well today.
