TR6 New Aluminum Damper for TR6

[hondo402000]

I see Damper dudes offer an Aluminum Damper for a TR6 2.5 pounds about around 200, is it worth going to New lightened one? Since I am spending my retirement on my TR6 Engine

My opinion, keep the damper stock and spend the money on an alloy flywheel. That should get you as light as you would want to go, on the street.

Might be a different story if you are going drag racing, I guess.

Note that what is really important is moment of inertia, which is related to both mass (weight) and the square of the radius. Thus, removing one pound from the larger flywheel has much more of an effect than removing one pound from the smaller damper.

Think he has the fly wheel already

Don you are correct, that looks like it was said with a frowney face, I didnt see a ! but Randal you are going in the right direction, does a damper do a better job of dampening vibrations having more mass? so would AL damper not do as an effective job? I dont mind spending money on things that are worth it but not just because its light

and Don just playing with you

Beats me. More mass might help, but I think maybe the elastomeric (rubber) portion is the important bit. From that point of view, likely anything new will outperform the original, old hard rubber.

From what Kas Kastner has said about TR6 cranks, I'm not sure a damper is what's needed anyway. Apparently the biggest problem is lateral flex rather than torsion. They measured some huge amount of runout at the flywheel surface, and blamed it on lack of overlap in what amounts to a 'stroker' crank.
