I'm considering going with an ICT 551780-2 for relocation of a Mechman 8206250 250A hair pin alt to the passenger side top left. Mechman pulley will be changed to a 2.5 to keep the alt RPM below 24000k and allow for 800 rpm idle, shifting at 7500 based on balancer diameter. There's also the GoatBuilt 4405-20-F relocation bracket I'm considering. The CBR bracket pictured below uses the turnbuckle as the tensioner.
2000 Camaro SS L96 block made into a 404ci Huron T6 V3 Turbo Kit with a FIS 488/102, 1.32 AR divided. Kit doesn't have a modified hot side to retain AC compressor in stock location. ATI F-body LS1 spacing damper 917276 (which also is 10% UD and supports belt driven AC) Lighter than a ATI 917302, and I'll just upgrade this damper that I already have from the 40 durometer to 70 using an ATI 91898070 elastomer ring kit. LS1 Water pump for now No AC compressor (going electric AC with a vintage air Gen 2 mini setup)
No Power Steering pump (going with Volvo S40 electric pump)
Downpipe mounts to turbon using a 5" marmon and necks down to 4" doing through the K-member to a 4" cutout so can't use this https://www.huronspeed.com/products/...on-bracket-set as I believe the tensioner where the factory alt location was at which could be in the way of the down pipe. I believe that's the bracket used in the image below (not my car, taken from Huron Speed website)
We'll see how it does, if too much power lost will just run a 5" downpipe, front bumper exit. Would love to keep the full center mount exhaust setup though.
Relocation of the alt to top left will require that it has clearance for the 2 wastegates, which should be ok with the ICT 551780-2.
On the fence about running a Sanden 04709-VMA belt drive AC compressor with the vintage kit, as that would require using an ICT bracket for the pass side and moving the alt to the top right. That would require brackets like ICT 551566-2 and 551474-2 or something like Qwik performance K10167 and K10471.
I think the alt will need to be clearance when using that ICT 551780-2 bracket.
Venturing into new territory using an electric compressor here with the vintage AC kit.
May run an electric water pump in the future like a Craig Davis, but have yet to research which one to get an what all is needed on that to make it run.
Rather stay away from LS3 accessory setup as that pushes everything forward for less clearance.
Thoughts?

Buy a JS Racing alternator, then you get full voltage from idle to 9,000rpm with needing to pulley down or up.
I run one on my turbo LS with tons of load draws and it works fantastic.
I'm using a hawks 2.85" pulley on my 240 amp AD244 alternator and I've also got the same ATI balancer (10% UD). I see 14.4v at 800 rpm idle all the way up to 7k shift point. With all that my alternator shaft speed at 7k is 16,653. Yours at 7500 would be 17,842

Yep, that 2.85 looks pretty good with that damper. I was told that alt shaft speed max should be kept under 20k and alt shaft speed at idle should be above 1900.

Yea exactly. I like to give it a little more cushion as a Justin case
