I have these they look exactly like my race version crank pulleys except the belt dia has been reduced to 5.5". This is the exact dia the pulley needs to be to have the belt clear. any bigger or smaller and the belt will rub. They are a little cheaper than the regular race crank pulleys because the chunk of material I start with is significantly smaller and cost less. $129
I would definatly buy one if i knew what was invoved in running an electric water pump. which model pumps are used on gns? surej
yes in the future, I am working on getting a kit together. for now the hardest part (the pulley) is done for you.
