Underdrive pulleys+smog pump delete= ??
I just finished installing underdrive pulleys and deleting all the smog. I am trying to make a 90.5" belt work, but I am not sure its going to happen.
Has anyone done this with success? Do the Mustang smog pump eliminators fit? I know I can gut the OEM pump but I don't want that thing back on my truck.
I am going to figure this out, just wondering if anyone else has traveled this road. Truck info in signature.

I really don't care about fuel mileage, but I do know hot exhaust gasses are not good for an engine wanting cool/fresh air. My truck pulls really hard and drive ability has improved.

why not get a 91.5 or a 92.5 belt...?
stretching one on the hard way is only going to make other things wear faster...the belt done give as much and the water pump will prolly go shortly....

I put the A/C delete pulley on mine from Summit. The Smog pump is still on but not being used hose cut- off in the back. I also thought about the stang pulley delete?? Not sure if it is in the same location- never really looked. As far as the A/C delete pulley I bought - I had to make spacers & get longer bolts to mount to the new bracket to the existing A/C bracket and to fit the normal stock belt as mine would not get tight enough- you would have thought the delete pulley would be the same distance???. It really just starts cleaning the engine bay up.
