Training to be a better climber

[bomber]

Back to the point what is the time penatly for any addition in weight when climbing?

As an example if you had 2 riders riding the same climb putting out roughly the same wattage but one of the riders weighed 5kg more than the other (all up with bike).

Just add % gradient, power, weight, shake well, press "Run Model"... then, lather, rinse, change weight, repeat. Compare speeds vs. distance. Voila!

And what you'll find is that on steep hills (>10%) the change in speed at a fixed power is almost directly proportional to the change in weight. For instance adding 10% to the rider/bike weight on a 15% climb slows the rider down by almost exactly 10%. On shallower hills aerodynamics become more important so you can't generalize to 2 or 3% climbs at higher speeds.
