So, is this what 2.7RS pistons look like?

I received a set of Mahle 2.7RS p/c's (8.5:1) for Christmas and, when I looked them over, I was expecting them to appear different. From a pic I've seen in Frere's book (pg 46), and from my shop manual, I was expecting a much higher dome and deeper pockets. The dome on these pistons is only a couple of mm's. Am I obsessing over size? Thanks!

Jim,
Even the 2.2'S dome looks small for 9.8:1. The only think that looks "good" to me is a set of 10.5:1 JE's that I've seen. (I might be running then if my new job comes through). I really suprised when I first saw pics of those too.

Yep, they're supposed to look like that. 8.5:1 is nothing.

They look the same a mine, not a very high dome, but 8.5 isn't that much.

left to right 2.7RS, 2.4T, 2.2S

Wow, I'm so surprised. They really look underwhelming. I guess all that really matters is the HP after I upgrade my 73E engine to RS specs. Thanks guys for your great feedback!

Aaah, no. They will have to sit in their box until that last 2004 DE. Then they can come out and play.

Jim - is it just the picture or is that rust on the top of the lower studs?
