Pro and cons on ati under drive pulley Hay guys just wondering if there is any pros and cons on the ati pulley I'm thinking of getting this for my ls1 camaro. Could it put strain on my water pump and alternator and Power steering. Not wanting to go with any other pulley here bad story's anout other pullys just want to go with the best one and I here ati is the way to go
ati is certainly the way to go. its only 10% underdrive mos of the hp with an ati is attained from proper dampening of harmonics. People run 25% all the time and have no issues my ati has been on for 4 years now and is just fine with all accessories even with a stereo system
I went with a 25% SLP (or Powerbond) many years ago and haven't had one negative effect.
I have multiple accessories running full time as well (progressive nitrous controller, N20 switches, triple gauge pod, shift light, etc) and haven't had any charging issues. My only disclaimer is that I don't have any of the big draw items such as an aftermarket stereo, amp, subwoofer, etc.

I run a gm 130 amp alt, mini 6 channel jl amp to power 6 speakers 100w rms per channel and a small 10" fosgate T1 sub powered by a kenwood amp. no problems. you will be fine

Go ATI 10%ud or standard, your engine will be much better off.
If you worried about the alternator having issues charging the battery, then I'd bump up the idle speed enough to offset the crank pulley UD percentage. You might also want to consider doing the Big 3.
