Whilst under the bonnet yesterday when I revved the engine hard (Defender 200tdi) I noticed the rubber turbo hoses flexing.
Is this normal? The one that seemed to flex (expand) the most was the bend on the pressurized side of the turbo. I'm guessing it expanded probably 1 or 2 times the width of the rubber hose wall, perhaps 10mm in total.
I couldnt see the hose onto the bottom of the intercooler - it was too much faff to remove the air filter housing!
I think Ive read before that silicon hoses dont flex... This
**theoretically** would mean more pressure into cylinders.Has anyone changed the hoses only and noticed any difference?? I suspect most will change hoses, intercooler & tweak fuel pump...
Silicon hoses are not cheap and so wont change if theres no *real* difference.
Thanks Jon
