Trying to decide between the two. I know they are both great but would like some real world comments from people that have them. I like that the a&a you dont need to remove waterpump housing and that they include an iw damper but on the otherhand ecs claims 500 torque at 3000 rpm so all your comments are welcomed

There are plenty of threads hashing this out if you want to search a little more. If you're concern is torque you want the ECS kit. The restrictor plate provides more torque and you also get a larger blower in the base kit. I've had both and no complaints with either setup. They are both top notch. If you aren't installing yourself, talk to the shop/tuner that will be doing the work and see if they have a preference and go that route.

DOUG @ ECS

Give us a call, "we'll make you an offer you can't refuse".

Obviously I'm biased, but the result wanted is your car to be faster, the base ECS kit will make your car faster due to the increased TQ then any other centrifugal kit on the market. While still having plenty of room to grow later if you choose.

Good luck with your purchase either way.

I can tell you I had this exact same crossroads 2 years ago and I picked the ECS kit for 3 reasons:

1) ECS gives you a bigger blower in their base kit and supplies restrictor plates to let you grow.
2) To turn your system up with with an ECS kit you can just remove the restrictor, but if you really want to turn things up all you need is ONE pulley change to the 3.75 with the novi1500 and you're at 800+ wheel. $100 extra
3) Doug and Chris's customer service won't be beat.

Thats 3 in favot of ECS

I sure do like my A&A Vortech kit.

When I did my research, it was very evident that any of the manufacturers will give you an excellent kit.

The couple of reasons I went with an A&A over ECS was the differences in intercooler design and the fact that I could get the A&A for a couple of hundred less (at the time, YMMV). I went with the free Ti-trim upgrade and did a methanol installation and headers and now have more power than the car can effectively put down. Wheee!

ECS all the way, great customer service

schpenxel

Pretty sure A&A includes the larger head unit at no extra charge..

Not saying one is better than the other, I'm staying away from that one, but at least make sure the things you're comparing are true

I haven't heard anything bad about A&A, but I personally went with ECS and have zero regrets. Awesome company and great blower. Its proven to deliver the most power over the others consistently.

A&A here, zero regrets! Their customer service is absolutely great. I will mention I bought my setup used so price was a factor.

Where do you live??? For me I wanted to stay CARB compliant. I have the base kit with a small pulley upgrade and Meth. I make over 600 to the wheels and have enough power to do anything I want. Car is reliable, fun, and drives a like stock out of boost. And the service in my experience is second to none.

I went ECS and have been very satisfied. Doug was a big help the few times I needed to contact him.

TPSMak

Both are excellent kits and I sell quite a few of them.. PLUS we offer 0% financing for up to 1 year

joemosfet

Heh, you didn't mention which kit you went with - but I believe A&A is the ones who have a CARB compliant kit.

Yep, got my kit through TPSMak, he offered me a better price than A&A did, at the time. That, plus the 0% financing sold me. He also got me the methanol kit at a great price, too.

TPSMak

Yup... the A&A kit is the only Carb Compliant centri blower at this time. Procharger is pending and ECS I don't think will apply for it. In most states having CARB Complaint/ Smog legal parts aren't a big deal... unfortunately in CA it does matter. We sell quite a few of both blowers throughout the world.... I just shipped a kit to Taiwan last week

Glad you and TeddyCA are both happy with your purchases

Thanks guys for all your responses although you are not making it easy. I guess Im going to end up tossing a coin. Do any of you AA guys take your cars to the strip and if you do what times are you running. I think thats going to be my tie breaker I want the kit that makes my car faster light to light or at the strip.The design even tho diferent are good on both kits because no one is complaining. And I guess for me at the end of the day a couple hundred more or less wont matter if what I want is the fastest kit

Here is a good thread that compares all of the supercharger options. ECS is on top of all the centri's. This is a base kit comparison. If you're looking for the most power and simplicity ECS is the answer.

joemosfet

^What do you mean by simplicity? (Also, that thread's graphs really aren't accurate, unless he's done the test with all those different setups on the same dyno back-to-back with the same conditions.)

In my estimation, when it comes to the centri kids, ProCharger's kit would be the simplest to install, comes with it's own tune, no manhandling of the ABS module, comes with pre-cut plastic pieces.

C7&7

I meant simplicity of taking the kit out of the box, installing and making the most power. Not pulley change this and upgrade head unit etc.

Theyre all good kits, and you're right the procharger base kit is easier to install but I'd argue the quality isn't there because of that.

joemosfet

I'm a little confused... are you saying that when making an order, saying "I'd like the free upgraded head unit" or "I'd like a different smaller pulley" isn't simple?

As for Procharger, could you expand on what makes you think that ease of installation equates to lack of quality? (edit: just note that I'm not saying you're wrong, or anything like that, I'm just curious. I actually went with the A&A kit based primarily on it's price, secondly on the intercooler air dam. But I do have a ProCharger kit on my dad's HEMI, and it's fit and finish is magnificent, just like A&A's kit on my Corvette. I had an Edelbrock on my HEMI before I crashed it.)
