A question for the dyno shops........ I am about to dyno my ls7, havent dyno'ed one of these before, was going to run a short belt around the damper and waterpump like I do on most engines, BUT.. the water pump runs opposite to the crank on these engines, just wondering how you guys set the waterpump up without putting all the accessories on or just let it turn the opposite way for the dyno pulls... Thanks Gaz.

Two Idler pullies/tensioners, one on each side of the water pump will spin it the correct way and is how I do it.

do not run it backwards. at least put the alternator on and run a belt from there and just bypass the PS pump. or find someone who has an electric water pump and borrow it.

We run our engine dyno w/ and electric pump. Makes it a lot easier to deal with.
