New 2JZ-GTE Waterpump

2.5RHDsupra · 06-18-2010, 03:43 AM

Ok, so i replaced my waterpump with a 2jz-gte waterpump, and i put in an electric fan, just wondering if i gained any horsepower out of this.

Don't know.... don't forget to calculate how much resistance the additional load adds to the system too though.

What you talking about willis?

Physics.

Alternators aren't magic... that extra power has to come from somewhere. To put it most simply: The greater the demand on a generator the greater it's demand on the engine driving it.

Oh, so i most likely didnt get any horses from it then.

This always kills me... other than what the garbage "we dynoed it with and without (two weeks apart)" writeups always say, just how many HP do you think it takes to move a fan while the air is already moving toward it? A few, tops.

If you've gained anything it's not much. It's unlikely that you've lost any, but I doubt you've freed much up and it's no more than you could have freed up with simpler and less expensive solutions like a new (see more efficient) water pump and an aluminum flex fan.

There's balance to everything, you can only ever go so far with something before you start incurring losses.
