Problem with a overdrive HB, it is going to over drive the Alternator as well, and the OEM alternator do not like to be over driven. When this happens, the OEM valeo alternator end up breaking its armature winding cages, with take the alternator at as well (can not be rebuilt to save it),
So if you are maxed out on the smallest pulley you can run on the S/C and still need to spin it faster, then its a option, but plan on having to replace the alternator with something that likes to be over spun/or look for an under drive pulley for the stock alternator isntead.

Turbo,
Can you tell me what's the deal with the Innovators West 10% overdrive crank hubs? IW and A&A sell crank hubs in 8 and 10 rib versions in normal and 10% overdrive. I thought that meant just the supercharger was 10% OD, is that not true?

I asked Andy at A&A, and he said that only the A&A IW hub is compatible with the A&A kit, not the ATI hub. Can't decide if I want the 8 or 10 rib or the seondary/flip drive. I want to buy once, cry once.

Hi All,
At 12 years old with 38,000 I think my '06 LS2 Corvette is due for a new harmonic balancer - it's starting the shaking thing. What do you people recommend for a replacement ? I've been thinking about an ATI unit. I know I don't want another factory one.
I use the Vette as a cruiser not a race car.
Thank You

So for a wet-sump LS3, which 8-rib ATI balancer do I get? I looked at a couple places, but the ones they had were for the LS7. Still can't decide if I should do the A&A secondary drive or not, which would require A&A's Innovators West crank hub.

If you decide on the ATI 8 rib call ATI tech line at 410 298 4343 for the correct balancer p/n for your application.the newer A&A billet tensioner would be a good way to go as you can change the belt in 10 minutes versus removing supercharger to change belt
