Temp BOV

[nikp]

Ok, i have a ball bearing turbo, and have heard it\'s not a good idea to run without a BOV. However, i\'m just running my engine in at the moment, so don\'t have one at all. I\'m just wondering whether it might be safe to install something anyway, just for piece of mind - and on that basis, could i use the standard twin turbo re-circ valve for the job on a temporary basis?
