Anyone know where I can get lightweight waterpump, alternator, and power steering pulleys? I'm already planning on an Underdrive crank pulley but that's the only underdriven one I want so it dont starve my AC, Power Steering, and cooling system. Any ideas where I can get stock size lightweight pulleys? Thanks guys!!!

 

just drill a bunch oh holes in your stock pulleys lol

 

Not a horrible idea except they would be off balance if I didn't do it perfect

 

Not to mention the pulleys would be weakened since they weren't designed around having holes in them. I'd ask around to see if anybody is having charging issues in the winter, or cooling issues in the summer. How much potential power/response are you hoping to gain with lighter pulleys and an underdrive crank pulley? Between the pulleys and an EGR delete, your car's bound to be a holy terror!!

 

I changed my mind on the EGR delete lol

 

Was it something I said?

 

Well Alternator HP requirement is based on what you are drawing in Amps not how fast it turns. Power steering HP requirement is based on how hard you are turning. I strongly suggest if you want to go fast in your 3.4 you turn the AC off. So that leaves the water pump in terms of HP gain. If you get 1 HP increase I would be amazed. This would be why no one sells under drive pulleys for the 3.4. Unless you plan on turning 7000 RPM and you fighting of hundreds of a second in the ¼ mile on a 10K motor they are not worth it.
