RS7 vs S7 engine differences

Sorry if a repost.

This is a great explanation of the difference between the 4.0 in the RS7 vs the 4.0 in the S7. I knew the bottom end was forged but quick a bit of other things were done. Pretty cool what they did to compressor geometry and intake.

Awesome! Thanks for the post. Glad to hear it's not just a tune that makes the RS7 engine more powerful, and that the price difference is paying for a lot!

Btw s7/6 only have one side mount inter cooler while RS has two.
