Outer Limits 4x4 Board

Just wondering how lng it should take these engines to warm up???

I have jsut got a hiace as a work van and it takes like 8k's to warm up and the gauge only sits at 1/3..

Just wondering if this is normal..

mine takes quite a while and stays quite cool... only ever heats up on soft sand at 4000rpm after 10 minutes.

Mine takes about 5 km's to warm up and has sat a needles width from half way every since I've had it
