ZZP underdrive pullies

[Firehawk N Wv]

Hey cuz I was considering getting ZZPS water pump underdrive pulley even though its only give 7hp or less. It would be cheaper than getting the electric water pump however. I also am considering getting the alt. underdrive pulley. How would using one or the other pulley or even both effect using accessories in the car. Also how much smaller or bigger of a belt woudl I need for the car.After reading Loochies sticky I see the pros and cons he put down, but what about you other guys who have used these.

Re: ZZP underdrive pullies

I wouldnt think the w/p overdrive pulley would give 7hp, more like 2-3hp at the crank
I would think it would give the alt a little more power
Its lighter
The 3.8Ls pulleys are already sufficient

Re: ZZP underdrive pullies

yea our cars are underdriven already and people don't see much of a gain from them, maybe like 3 peak hp at high rpms or something.

Re: ZZP underdrive pullies

would you see bigger gains with an electric water pump?

Re: ZZP underdrive pullies

maybe if you upgraded the alt.
underdriven alt, overdriven w/p
I've heard that converting from manual to electric power is a waste, due to the loss in the conversion of power.
Its cool you can cool your car down any time you want, whether the car is on or off
