Problems after crank pulley replacement

[BloodfaceRobert]

Recently I had my cam shaft pulley go out on me (separation between rubber ring and pulley track). I ordered a light weight performance pulley to replace the old stock pulley and put it on no problem. After the repair was completed, the driving performance has been absolutely awful. At colder temperatures the engine refuses to accelerate faster than crawl and refuses to go above the rpm for turbo spool up. After it gets up to temperature the turbo still has no effect on the acceleration and the car runs extremely rich in fuel (i have a air/fuel gauge added to my dash) and runs hotter than it normally would (close to 210 degrees F).

The crank pulley replacement should not have affected anything other than the alternator and water pump if anything at all, but this problem arose right after the crank replacement was complete. I have checked all of the air intake components as I thought that might have been the problem but everything is in order. The car is drivable, but the performance is nothing close to what it should be. Please let me know of any ideas of what my problem might be know where to start to fix this problem. Thanks.

Did you ensure that the timing is correct? I had an aluminum pulley a while back and the timing mark wasn't easy to see, so setting the timing was difficult. Also, since it is connecting to your water pump, it could be affecting your temps.
In the end I really didn't feel that a lightened crank pulley was worth the gains (if any) on a daily driven car.
But anyway, check your base timing first, that will definately have an effect on your driveability. Make sure it is at 5 degrees btdc. Plus don't forget to ground timing when checking it.
