Default " csr- performance electric water pump"

hi there guys,
i was just wandering if any one has got or used/ran a csr -performance electric water pump at all please?
i have a 1991 L98 engine!

do they make a pump to suit the L98 engine?

if so are they any good?

has it been reliable?

what rough horsepower gain please?

i spoke on the phone to the csr tech guys ( david & Jason) and they assured me that the # csr-901 will fit my L98 engine @ $ 269.89 u.s dollars, avaialble in red,clear,blue color!!!!
to suit engines small block chev 283,350,400 chev!!!
gee i hope he is rite.
its a long way to have to send it back to them isnt it!

i am hoping one of you guys has one or tried one on your L98 engine!
they said i will have to buy a new shorter sepentine belt and installtion is quite easy!
they also said that the pump only draws 5.8 amps and weighs 8 Lb and comes with 1 year warranty!

here is there details
www.csr-performance.com

both CSR and Mezeire make high quality electric pumps...

your L98 is nothing special...just a typical Gen 1 small block. the pump should fit just fine...

rough gain? 5-10hp? depends on application...some gain more or less...

you would need the shorter belt since your engine is no longer driving the pump...installation should be no more difficult than a standard water pump except you need to run a couple wires for power and ground...no biggie...

i plan to convert to one on the 427 if it ever gets finished.

I have the csr on an lt1 , don't know about any gains in power but they told me 5-7 on a stock engine ,also its cheaper price wise than a mezzeire and just as good.

There is no question about fitting it, but does the kit include the changes for the belt routing?

Gday Glen, im still very sick mate, How are you?

Youve removed your A/C so the compressor doesnt need to be there, electric water pump means there will be no pulley on there, all you have left that needs to be driven is the power steering and the alternator, which are both on the left hand side. Im not sure how youre going to make that work yet, but it wont be as simple as a shorter belt.

You might as well get rid of all that stuff that doesnt need to be driven anymore, if you leave it there it basically defeats the purpose of disabling it.
