Sounds good Steve but be careful 2.5 don't like more than 1 bar boost !!!!

Hopfully with lower compression from 9.37 to 8.32 this will help

I'm trying to get round it in my head how at the same boost I'm so much more down on yours Steve. Re profiled valves and porting along with the lower compression is the difference. Could it be just the 28's?

I'm not sure how true this is but I'm told its not what boost your running but the power its making that will take the head gasket out on the 2.5?

So if at 1.1bar and running 450 or running 0.8 bar but 450 then the head is still under the same pressure?

Thats interesting as I'm about the same and at max power my boost is around 0.9 also?

What are you at the wheels on 1 bar?

This kind of chat makes me more devasted than ever that some f***er is probably driving my Nob around in eastern Europe somewhere with a load of Ray West's tools in the footwell.

Next thing to rub salt in the wound will be a sunny bank holiday weekend to really rub in my lack of Noble in Hampshire for the weekend showing bikers how to drive properly fast frown
