I am having the stage 1 put on my 2012 GS soon. That kit does not have a blower, but will use a blower cam so I'm ready if/when I add a blower.

I have talked with Taylor at Dallas Performance and while he agrees it is a personal preference, he and most people favor a centri vs. PD on our cars for a few reasons such as weight (our cars are much lighter than most and don't need as much boost down low to get going), cost (generally cheaper than PD), and pulling a bigger number (centri acts more like a turbo and can get you a higher HP number).

FYI Taylor at Dallas Performance is considered by one of the best tuners in the country, and he pulls bigger numbers with ProCharger than any other system. This link shows you all the systems they have and what the max HP is:

Personally I think ProCharger is tough to beat. Mine's been on for 6+ years and the single problem I had years ago was rectified pronto. People talk about customer support...well ATI has that covered!

This is the one that I'm considering and think certain that it will pass tech @ the local IHRA Track.

Before buying a Procharger I suggest that a person speaks to someone who's not selling them.

Then ask yourself: Why is this kit $1500.00 more than a A&A?

saplumr

So basically what you're saying is....talk to someone who can bash a ProCharger then say how great the kit is that person sells? Not sure where the logic is.

^^^All of the above + Procharger has the best headunit selection on the market, that's a very big deal imho...

I don't sell A&A kits and when doing my research prior to purchasing an A&A. It became clear to to me that Prochargers have a high seal failure rate around 15K miles. In addition, it is common for Procharger owners to UPGRADE to A&A bracket/pulley technology.

The purchasing decision finally came down to Edelbrock or A&A, and choose the A&A kit $5325 delivered!

I then performed my own installation and the tune was then performed by a local shop. Boost upgrades on the A&A are relatively inexpensive compared to other Centrifugal Kits.

I am now @ 10#'s boost w/Alky Control meth kit and total investment is less than $7K.

Perhaps these Procharger owners must have it all wrong?

It was overfilled and I drained it to about 3/4 on the dipstick so hopefully it was just that and a small leak on the drain plug.

I would call procharger regarding this. I too did the same thing and STILL had the squeek issues, there's a thread on it in here. Another member stated that they to had done the upgrade with the same results. They stated that when they called procharger he was told that he should have also ordered another spacer kit that goes with the tensioner upgrade....like we should have known that. I said enough is enough and went out and bought the A&A upgraded brackets....I'm not looking back. Just food for thought.

I've had a Vortech SQ I couldn't junk fast enough. Moral is junk comes in all forms.

Hey guys, look.. Andy at AA will be the first to tell you that he uses the same head units. If your going w/ a centri I would personally choose
AA. Andy has so much experience, and is so cool as far as explaining everything you need to know. I don't own a centri but if I did.. AA is the way to go. I have raced, and built many many engines. I prefer PD blowers, however they are limited if you want to use meth. If you want to chase HP you will never end. I've run 1000hp. It just depend what you want?? PD low end torque, centri upper end HP.. do you track your car? If you run under 11.5 plan on spending $$ to cage your car. Do you want a roll bar?? I don't in my vette.


If you want to use your power at the track consider the options.. If you just want a bad *** street machine add a small torque converter to your blower.. I had to cancel my converter because it was going to force me to cage my car.. I have cage one car that takes allot of the street out of the car.. IMHO

I didn't want to say anything negative about Vortech (and it certainly was not about A&A) but I felt it necessary to say we can all can have negative experiences. It gets a little old when people who've never had a particular product speak about quality issues. Mine are real world experiences....not hear say.

Exactly, and same goes for those that haven't flogged both blower kits hard. I have. The only one I haven't is a procharged vette, but I have driven their mustang kits quite a bit years ago.

ECS has my vote on the blower debate, but again, to each their own.

captainbob

I've run a pro charger.. I prefer PD, I love my eforce..

ATI can't control installers that don't properly align the blower and pulley system.

txvettefan

This thread has been a blast..........engaged people will from time to time disagree.

Detoxx03,

We need to get together in SA @ the track "PROCHARGER 9psi w/ cam & headers 6 speed vs A&A 10 psi w/meth LS7 exhaust A6-Stalled!!!!"Louisiana vs Texas................................... Winner buys the beer!!!!

Thanks again to everyone and I hope I didn't needle too hard.

Best Regards,

Their tensioners do have a tendency to get thrown off alignment. There's definitely a gap at the top of the tensioner that isn't there at the bottom. Not sure if it's the tensioner itself or the install but I've seen a lot of issues with the tensioner and bracket in general.

Don't get me wrong though I love my Procharger I'm just a little annoyed that I can't really get into boost that much... or the fact that my belt can fall off the tensioner at pretty much any time.

saplumr

It can take a laser alignment to get it all perfect.

12,000 miles on my A&A kit making 677rwhp and 600rwtq and it runs like the day it was installed. Just change the oil in the head unit every 7,500 miles or so. Absolutely zero issues so far.

shootincyclone

That much lag to where you arent churning and burning rubber until top RPMs? I had a lot of fun in my LS3 before putting on the blower doing just that

Detoxx03

Next time I'm in Mercedes or San Antonio that is fine with me. Oh you will have to get your facts straight first though. I don't have headers (yet) and its on 7psi.
