I know the water pump works in the same way that an UD pulley works, by freeing uup horsepower rather than adding it, but how much of a gain is usual? my friend said he got about 10-15 of his formula. does it depend on the rate per hour??

 

most searches i have done on the subject come up with around 10 ,,no idea on the rate per hour part of your question.

 

whoopsss

**gallons/minute

idk if that affects it, but since their are so many different choices, i just thought id throw that out there and see if it is any different. very good chance im going to look dumb for that , but oh well, im learning

 

so many choices?

there are?? i was only aware of one company making a electric pump for the LSx engine...meziere.

since its electric the flow should have minimal affect on the power gain.

but 10hp is about right i would think...maybe more if you're spinning REALLY high.

 

I'd say its more about getting better gas mileage. You only see more power by reducing the parasitic load on the crank. After my pully and ewp were added I began seeing 4-5 mpg increase on the highway. No bs.

 

There is a dyno sheet on LS1howto.com but seems like a lot of bucks to spend on getting 6.8 hp and 4.7 torque.

 

Yes it is a lot to spend, but when you want to build a max effort engine, you do everything you can. Now that gas is $3.50 to $4 a gallon for premium the extra gas mileage helps offset the expense. I have had mine for 2 years now and it works GREAT. Zero issues to speak of.

 

What isnt expenisve for these cars,,,

 

and that power gain is only peak.

this is a mod that boost power all over the rpm band, not to mention helps keep the engine cooler under hard conditions.

 

they have a lifespan of what? something like 2500hrs??? that might not sound like much, but if you drive 1.5 hours a weekday and 2 hrs on the weekend thats almost 4 yrs lol.....just pray you short it out

 

im talking like 20g/m, 55g/m, etc.
