it really wont add too much power (maybe 5-10 hp) but if u dont use the air pump, why not just buy them along with a shorter belt so you can disconnect the air pump alltogether (if u haven't). then it wont be just a worthless piece that still gets powered by the belt.

It's a good idea to get a pulley kit when you remove the airpump, the stock water pump pulley is too small to make safe contact with the belt. If you look at how the belt runs w/o the air pump it is easy to see how it has the possibility to slip and prevent the water pump from turning.. very bad.

my friend overheated his car that way, with out the airpump it doesnt have enough contact

i'm not a fan of pulley kits

Neither am I. I only have the greddy pulley kit...and that's just to get rid of the Air Pump.



Since I don't have a/c or p/s, what's the use of having pulley's? https://www.nopistons.com/forums/pub...1047683664.gif

dynoed 6 additional rwhp with the indigo full kit...

but there were other factors during the session...

high temps bein one of them...with power steering..

insignificant gain to most but hp is hp

i have the greddy pulley kit because it came with my T78 kit https://www.nopistons.com/forums/pub...IR#>/smile.png



6rwhp for $400+ is not a good investment for me https://www.nopistons.com/forums/pub...1047683785.gif
