You can cruise at 350 degress with no issue even 400 degrees but you want the temps to remain stable. Andys setup has awesome potential to get this near spot on and it will be even better to drive even at his current torque/ power levels.
This bit is very interesting Mat. I have always thought quietly in the back of my head about this. But I don't really have the knowledge to back it up....The boost on my Patrol drops off quick quickly, and there pretty much nothing after this. I was told by many it was because of the restricting intake. This is all changed, and the boost drops off just the same. Wish there was someone down here that looks into stuff this more. I feel like a dickhead when I go to a workshop and try to explain this and they just look at me with a blank face then chuck it on the dyno and just play with the pump.
I might have to take a week off and go for a drive north. Lol.
