I'm just in the process of changing it to a Small Oval 83mm which should fit OK under the bonnet, and is rated for engines up to 175bhp. The one on at the moment is rated for 100bhp, which is sufficient for a standard crossflow.


Thanks for the pointer. Is the change just wishful thinking or are/have you made "improvements"
