Im about to order a centrifugal setup for my car and am also gonna do a balancer while im at it. The goal is high 9's so probably around 675whp. Im trying to keep cost down as much as possible so should i be ok on 6 rib or should i do the direct drive now. It looks like it adds around a grand.

Depends on the pulley sizes used and bracket. I was experiencing belt slip on a A&A kit with stock Z06 balancer and 3.4 blower pulley. Once belt stretched, it slipped. Secondary drive going on soon with 8 rib.

ECS 1500 will be fine on 6 rib at that level

Haven't used a&a's new billet tensioner so can't comment on it.

I used a ProCharger bracket and 6 rib at 780rwhp with no issues before I did a new round of mods and switched brackets and went to 10 rib.

Go with the direct drive and never look back. You should be able to upgrade it for $750 since you're not using some of the parts on the "standard" drive so the cost for those parts should be backed out. Adding it in later will cost more.

I went with an 8rib HB just in case but still on a 6 rib pulley and belt for the blower. No slippage yet.

PS: High 9s = more money

If you ever plan to turn it up, it's much easier to do it now. I didn't think I would ever need a secondary/direct drive and well, here I am.

8" balancer n 3.4 upper 6 rib no slip at 720 whp

Although I agree that going fast does cost $$$$, but we have had so many guys hit high 9's with our kit, meth, headers and a drag radial that I have lost count. Or with the addition of our stg 1 fuel system.

A direct drive is the way to go with a larger belt if the funds are there, but it has proven to be not necessary dozens of times over the years now.

OP, I have found 700 rwhp the to be the number to be at to hit high 9's unless you have a really big stall convertor etc.

Hope that helps.

I think if you're buying a balancer and kit may as well get everything in 8 rib setup while it's all apart. I'm at 8 rib on 900whp and it's on the edge but working well. no direct drive. make sure you laser align everything perfectly when you set it all up or you'll get slip and issues no matter what you go with.

Are you guys selling direct drive kits anymore? I haven't kept up, last I heard there were concerns over modifying the balancer or people screwing up the cog belt installs or something

It has a stage 2 btr cam and full exhaust. I'm most likely gonna run a 3c.

I think they have been selling/using the cartek DDs forever now. The COG thing kinda went away, but not the cartek DDs.

schpenxel

Ah ok that makes more sense then

so in a nutshell, I buy a direct drive for my ECS kit and deal with belt squeal and such. Or I keep my current 6rib ECS kit and roll with a spare belt in case I snap it under high and long term load (1/2 race events). Or other option is to ditch the brackets and buy A&A's and their new direct drive with the 3 belt system and solve the issue but I am out a couple grand.

Flip/direct drive. Less ribs will allow you to swap belts so much easier. That blower kit has been taxed out my myself and many others in here. I've run the ECS kit to 850rwhp. Ty ran his to 925 on a 6 rib. Direct drive is awesome. I've had all 3 brands and they work great, but I'm pretty sure DP doesn't make it still due to a copyright claim though DP improved it.

No need for new brackets/etc. The A&A DD will work with ECS/Procharger/etc.

I'm running ECS bracket, A&A DD upper, Dallas performance ECS modded lower. It is a hybrid system. The DD doesn't care what blower bracket/setup you have.

Heck yes! That's what I wanted to hear. My local shop that does install and tuning is now an A&A dealer so I read that the ECS bracket is set up for 6 or 8rib. If that's the case then I'll order the A&A DD with a new IW Balancer and rock it! Thanks again! Man...I owe you a beverage of choice if we ever cross paths!
