me too thats why when the time comes i will get a regular aftermarket with better flow...i think most of the LS2 stuff fits the LS1, i know the thermostat and waterpump do anyway and they claim to be improved

 

yes it is worth it.
I installed my cam after that in two weeks I installed an ASP underdrive pulley, big changes

 

LOL Me too Edelbrock makes a really good aftermarket pump.

 

I like the idea of max coolant flow at idle, but arent any of the gains power wise made by an ewp counter-effected by the additional load on the alternator?? Just as an estimate reading around i read that on average a 25 amp load on an alternator uses approximatelly 4 horsepower. I have no idea how many amps one of these uses, but I was just wondering. Im just saying that there is no such thing as free power. that waterpump no matter how it turns is still using the same amount of energy. Right?

 

Made a difference on mine

 

As best as I can remember the ewp is tied into a 20 amp fuse. I have never heard anything about amps = hp. Can you link a source for that comment. As far as free power goes, its not free, I paid just over 500 for mine. LOL. However when you reduce parasitic drag on a motor they do become more fuel efficient. They also tend to wind up quicker.

I don't believe it uses the same amount of power. I made more power with it and get better gas mileage. Something is working correctly.
