great stuff! look forward to some customer experience showing this fixes the alternator belt slip issues.

The_Nigel

Even better! Thanks for the reply

Cant see this changing much on the alternator side. Best fix for that is an alternator that puts out full voltage at low rpm, so even if it did slip a bit, there would be no effect.

my thinking exactly and I got the highest billet tech alternator available but ECS said they have logged alternator drop at higher rpm on long pulls even with the billet tech.

I don't know how long they are talking about. My voltage never dropped on any that ive logged, but I doubt any are longer than 10 seconds.

I think for your automatic transmission setup is maybe easier on the belts too though?

i will say although my setup is not flip drive but with normal straight 8 rib I have not seen any voltage drops at high rpm with billet tech even in 1/2 mile pulls, and even when I was seeing a little belt slip on the blower so I would have thought billet tech would be the solution here too but losing some fuel pump voltage in a standing mile pull could be gnarly even if momentarily. billet tech great upgrade even for stock vette imo so win/win to do it either way.

A&A and ECS would have more data and logs for these flip drive setups though so I look forward to seeing more data from them.

The 4 rib ac belt slips on the jackshaft. This should fix that. My similar setup fixed it. This will alleviate the extra load on a tiny long 4 rib ac belt, and put it on its own dedicated belt with more tension. Much better design.

will this work on an ECS kit?

You'll need to have the balanced to accommodate the additional 4 rib belt but yes it will work.

I'm about to go forward with my A&A blower kit on a C6 Z06. What setup on your kit should I use that incorporates the newest design, and should I consider going with an 8-rib setup now on a t-trim so I don't need to upgrade later if I build the block and turn it up?

Unreal

IMO just stick with stock stuff, and then later when you want to turn it up, do the 8 or 10 rib with their new DD design. Either all or nothing.

tuboy19

I would personally start with the 8 rib balancer designed for their new secondary. Even if you don't utilize it yet, the crappiest part of the job is if you have to pull the rack back out to upgrade. That being said... you'll find the safe limit of your LS7 before you'd actually need the secondary drive stuff. Honestly it's spend the money now or spend it when you want to turn it up - let's be honest, we all turn it up.

here you you go.Im halfway with my install.using Andys 2ndary drive setup.I dont see no belt slip on this setup.

What would be the difference in this compared to the ECS direct drive??

Unreal

ECS doesn't make a DD. They use a cartek system. It does not have a dedicated drive belt, it uses the AC belt like the older A&A setup, or DP setup, or PC setup.

ECS did do a cog mod which was basically this but a small cogged belt instead of an autotensioner ribbed like this, but last time I checked they are not doing that anymore because people are clueless when it comes to using a cogged belt.

Like Blk 08 C6 - I'm in the midst of installing the secondary drive from Andy. After 2 bearing failures with my 1500 SL, Vortech worked with me to get me upgraded to a 2200HD





Blk 08 C6 - I see you've got the belts on already. According to Andy and the installation instructions he sent me, it's kind of "tricky" to get the belts on. How'd it go for you?

Unreal

Can't speak for A&A as mine is a A&A/ECS/DP/Custom hybrid setup but AC belt goes on first like factory. Then the middle belt. Typically I had to put it around the pullies then move pullies into place and tighten them.

Then blower belt is just normal, and DD belt is normal.

M M Alexander

This is the part that I can't mentally picture. There is a tensioner on the A/C belt (as seen in my previous post - bottom right image) that has to be opened. According to the instructions, I must also open the supplied A&A tensioner as stated here:



Just to get to the point of holding the dual pulley for installation as stated here:



I'm quite sure I can accomplish it - I'm just attempting to gain some familiarity with the process before I start on it.

M M Alexander

DUH ... I just figured it out ... I'm an idiot and didn't recognize the A/C belt NOT having a dog in the fight ... as you said "A/C belt goes on like factory"

Unreal

Yep, looks like A&A does it just like what I have to do. Pop the jackshaft pulley off, then line it up and tighten it down, then the tensioner. AC belt on the other side and not involved at all.
