Does the damper being upside down affect engine preformance? Is the damper the same as the harmonic balancer. Isn't that torqued to 300 foot pounds? A ***** to get off?

damper and HB are one in the same, torque is 218 FT/LB.
The only issue you will see is that you have no idea how to time the engine as the marks will never be close to the pointer. Otherwise if the damper was installed after the timing marks were lined up then its reasonable to assume that the timing of the belt is correct. The only way for you to do this is to line up one of the cams the other cam should also line up then remove the damper and flip it over then the TDC should be lined up correctly

So I can I just take off the Jesus bolt and pull the harmonic balancer off or is there more to it?

remove the crank bolt its a 27MM,
and then remove the V pulley and the AC pulley, then the damper will slide off, flip it over, then install the AC and V belt pulleys, and the the crank bolt. While the damper is off make sure to check that both of the thrust washers ( belt guide plates) are on the crank the correct way.

How do you normally recommend locking up the engine to get the bolt off?

With a flywheel lock, about a $60 piece from roger. It gives you control over the situation, lot of force involved, and you want to be able to torque it back.
There are other ways, with two people you might be able to hold the flywheel with big screwdrivers. Pretty much need 3/4 inch drive for the bolt, 1/2 inch stuff usually shears. BTW, 1 1/16 is same as 27mm, I've used both sizes, no difference. Some have put the socket on a heavy 3/4 handle and propped it under the car, using the starter motor to turn the engine and loosen the bolt. Seems risky but some have done it. Doesn't answer the question of how to torque it back under control though.

Dude, take pics of the Harmonic Balancer. The HB will "sometimes" come off easy. My Euro wasn't the case, you had to use a large screwdriver to pry each side slowly to get it to come loose. My S came off fairly easy. You already know the large bolt that needs to come off, you can plainly see it can only fit two ways. Merlin is trying to get you to fit it the other way. I say, take a pic to verify this even needs to get done.

Dano see picture in post 39 thats his damper, its clearly facing the wrong way.
Mixy Get the lock tool from Roger Azone will not have this tool its special to the 928. pull the damper off and turn it left side to right then put it back on, this while looking at it from the top .. Simply put you want to be able to read the numbers on the damper while your facing it, the numbers will look like the picture I posted its simple Bro OK even more simple remove the V belt and AC pulley, then with a markS A Lot marker put a circle on the front of the damper, pull the damper off, then flip it over so the circle will now be facing the engine instead of the front of the car. NOTE the timing marks will line up on the damper after you have gotten the cams at the hash marks first. The crank will be at TDC if the woodruff keyway is at the 4 O clock position while your facing the engine

Got it man, didn't see this one. Yeah, Your Harmonic Balancer is on backwards. Take it off and put it on the other way.
