2010 RGTM8 Which head to run?

[SledderX]

What is everyone doing this year for a head on there 2010 m8 race gas turbos? With that new motor and stock head giving a compression ratio of 13.5:1 or whatever it is, does not sound very good for a turbo application. So are guys simply going to an 09 head with the little lower compression, or does speedwerx, rkt, bikeman, d&d, or sombody make a lower compression turbo specific head for the 2010 already? Thought the 09 head would work but am hearing mixed answers about this. The 09 head also is a fairly high comp for a turbo, but guys ran that head last year on there turbos. Couple people at the edmonton sled show this weekend said that the 09 head will not match up or work properly without some modifications to it. Any info or help would be great. Will be using a boondocker mini intercooler and good fuel if it makes a difference. On 12lbs boost.

09 head works just fine but the 2010 will not work at all. You can call someone like RKtech and he will make you one. I also heard that the guys at Twisted were just exchanging 2010's for 2009's but if your not using there kit who knows??

At Twisted we have been using the 09 head on the 10's. But we have done work to them also. We are currently working on the 10 heads and when we can get some testing on them we will have some answers about them. You can give us a call we might be able to hook you up or at least a exchange on one.

160 ish HP for a 2010 M8 @ 13.5 comp ratio.
Install a 09 head, lower comp ratio and lower base HP, 140's?
Say a turbo at 10psi gives a 50% increase in HP (DON"T GET ALL BENT OUT OF SHAPE! IT'S PURELY AN EXAMPLE!)
2010 at 10 psi should be 240HP
2010 with 09 head will be 210HP at 10psi

Got a fresh bowl of popcorn and a whole case of
