I was talking to my mechanic, Vettemaster, the other day and he said he's doing another ATI car right now. Apparently, they have reworked the entire bracketry? Has anyone seen the new setup?

I was told it was very nice, something about "two tensioners"? I really have no idea what the mechanic was talking about, but I wanted to see what you thought?

 

yeah, the new kits from ATI have new brackets, new tensioners, and a new fan that flows 400 cfm more than the old ones. i have all the new stuff now and can take pics of everything if there is any interest.

the new stuff did fine with an 8 rib setup on an 800 rwhp c5.

 

<yawn>. Give Chris @ ECS a buzz and get a real ProCharger kit. Their SIC is *huge*. 85% belt rap. Terrific kit and a very reasonable price.

I would love to see pics of the improved system.

Contrary to what some here like to think, the guys at ATI know what they are doing.

 

 

They are soo good that A&A and ECS had to come up with their own kits.

Mark

 

this should be good

 

Yeah Andy's solution to "better" involves cutting up your radiator support and 7" long silicone tubing that doesn't even align with the metal components. And "no welding" means "chop up your car and bolt it back together with these here parts."

And good luck if you have a factory tube-and-fin power steering cooler on your Z06 or Z51.

...I'm mostly teasing. I know Andy's got a good kit. Just wanted to throw some xylene on the fire.

I'd like to see pics of the ECS kit and how it's different. Can anyone share?

 

Have you personally had any experience with Andy's ATI setup? I don't know know about your A&A setup, but mine also has a custom polished pulley bracket that eliminates belt slip, as well as a large single intercooler and yes...the silicone hoses for better breathing efficiencies. Upgraded fuel injectors and fuel pump/booster are also part of his setup. 600+ RWHP speaks for itself.

Did I mention it has been 100% trouble-free? Amazing what true R&D will do...

 

Some of you guys are so clueless. Why do you always feel the need to wear kneepads for your vendor of choice and be so close minded? There is no need, Andy and Chris already get blown every day (you know they install at least one supercharger a day ).

Yes, I was one of the original ATI kit owners and yes I went through all the pain of a kit that had some major flaws. I was also the first person to self install Andy’s original FMIC kit and I have spent countless hours working on my car and trying to resolve all the issues that come along with FI.

I’ve been a customer of A&A and several other vendors and I think Andy is absolutely one of the best. I’ve also spoken with Chris at ECS a few times and I’m convinced he is also a great vendor to work with.

However, I’m not stupid enough to think that Andy and Chris are the only people who know how to put together a set of brackets and some tubing. They obviously know quite a bit about putting FI on a c5, but they are still learning a few things too.

I also know what it is like to be an engineer working for a big company. You don’t always get to solve the problem the way you would like to or get the opportunity to do revisions in a timely manner. You are also constrained by requirements that a small vendor never faces (government regulations, legal risks…..)

I have no loyalty or affiliations with ATI (besides owning one of their head units), but I am willing to guess that they know how to build some bracketry that works (given enough time and test vehicles). After all, they do build superchargers for a living and I’m sure they have a few engineers who are not complete idiots.

It also sounds like there is a c5 making 800RWHP with this revised kit. Not to shabby if you ask me.

So if you are just a cheerleader (shut up) and let the rest of us see some innovation.

I would also like to see what the ECS setup looks like. That one never seems to make it into any pictures for some reason.

This post was not about A&A/ECS vs ATI. It was about the new ATI bracket setup and if anyone knew anything about it. Let's keep it at that and not make it a big cheerleading fest.

 

very well said.

actually, i think it was making closer to 850rwhp (847rwhp if my memory is correct) with the new ATI 8 rib setup.

i'll see about taking some pics when i get home.

 

Soooooo where are the pics...............?

Edit: ooops beat to the punchline

 

Quick,

First, if you were one of the first ones to get hosed by ATI, then you should remember the excellent customer service you recieved to questions about overheating and belt shreadding and the satisfactory response you received. Oh, I'm sorry you had to call Andy and spend more $$$ to get you car working again. Hmm? Well, I'm one of the lucky ones that heeded the cautions expressed here and I have been completely satisfied with the A&A setup. Thanks, I think you were one of them.

As to your opinion of the ATI having qualified engineers on staff, Sure they make a good blower, but seem to be lacking in the bracketry dept. I guess the rush to make money from unsuspecting corevtte owners prevented them from fully testing their product and potentially put car and driver at risk on the public roadways. That's is irresponsible of ATI. My guess is that their new brackets look similar to ECS or A&A. I could be wrong as I have not seen them yet. But it would be fair to say that anyone buying from ATI directly should be leary.

Cheerleading you say, When you have at least two vendors that focus on the C5 and the owner in order to produce a reliable power adder that can be driven daily, I say let the world know.

Lastly, Let's not spit in the eyes of the folks who have made SC'ing availble to the masses.

ATI has a great head unit and for now that's where it ends. I hope they figure it out soon as they are loosing money to the ones that have.

PS I always enjoy your perspective.

 

F ATI.

There is a guy on Z06vette.com who has been talking about that 800rwhp ATI kit for months now.....making that much hp on the dyno doesn't guarantee anything..there is no load on anything other than the rollers on a dynojet..very little chance of the belt slipping. What has not been mentioned is the fact that they also are using higher flowing Twin I/Cs than the previous kit...but all the bends and the two Y pipes still exists, and they kept that POS single fan design. I am not convinced that ATI can build a good C5 kit or Fbody kit (Fbody's have had as much belt slippage problems as the C5 if not more). But ATI does build nice head units...there is no doubt in my mind that the D1 is a great blower.

Here is an interesting fact. Recently my Duramax had an injector problem..and many others did before mine. GM after verifying there was an issue at least recalled and warrantied the defective parts.

Now Vetterdstr, Bluethunder, and myself were among the first 3 people to get the D1, P1 put on our cars...and we called ATI, and then we watched the countless others call them, and then the FBody community called them...did they do anything...NO..they could even engineer the inboard idler pully bracket to the correct thickness, there was guy on here 3 or 4 months ago that purchased a brand new ATI kit for his C5 and guess what???? He had the belt shredding issue..that was associated with the inboard idler pully bracket being too thick.
Maybe ATI doesn't suck...but their Quality Assurance/Quality Control does...and when that isn't corrected and Customers are not taken care of..then that is bad business.

 

Wow, all kinds of things flying left and right here. Let me add another thing then I'm no fan of ATI's tech support or bracketry either... but regardless of that, I'm VERY interested to see their new setup.

The 800 rwhp Vette sounds impressive... but is the claim that all this extra power is coming from the new ATI kit, or just that the new ATI kit is capable of supporting that kind of power (i.e., no belt slip when it was dynoed)?

 

Well, I was originally just curious to see if anyone had seen the new kit.

Since the thread is officially hijacked, here's my take on the subject:
1. I had an original twin IC setup from ATI. It worked great.
2. I had one problem with the idler pulley seizing and ATI sent me a new, corrected one for free (no problems)
3. I have nothing but positive comments regarding ATI and their customer service (Based on my personal experience).

On the other hand, my car was totaled and based on info from other rmembers on this forum, I contacted Andy. I can say, without a doubt, I will purchase all of my future Vette mods from him. His setup, especially the reconfigured tubing, single intercooler and the ability to maintain the stock fan is perfect. As for ease of install, I will have to wait and see what the Vettemaster decides.

I am now having his setup installed on my replacement Vette (along with his cam).

I will try to get pics this weekend, but I will see Andy's setup right next to the new ATI setup (Vettemaster, the mechanic, is installing both right now).

If it comes down to the question, which setup should someone buy if they have a choice. . .go with Andy's (I am sure Chris also has a similar setup). However, is there something about the new ATI kit which Andy or Chris might want to adopt in newer releases of their kit? Maybe we should wait and see the new kit before deciding?

 

Like I said the new ATI kit has been out for sometime...don't you think if it were all that we would have heard all the great things about it. The 800rwhp was not on a 346cid either. I never even bought Andy's kit. I purchased the first ATI kit and lowered the RAD with Andy after talking to GWP...Kenny at Golden West Performance was the one that came up with all the RAD being lowered and the Single I/C. I kept the twin I/Cs and made good power with them, others made more with everything being the same except less plumbing and a single I/C. The fact hogurt that you are one of very few that did not have any problems with your kit and that many others did. Describes exactly what I mentioned above. It is a Quality Assurance/Control issue within ATI. Don't be so blind as to ignore all of the ATI owners in the Fbody and the Ybody arena that had issues with ATI's C5 kit. Here is the scoop the new kit uses bigger and twin IC's and basically MMS brackets (according to the guy who has it). If thats the case you can throw all that **** in the trash unless your on the dyno.

I would stick with Chris, GWP, OpticZ, or Andy's ATI setup for track, street, and dyno dependability (in that order). Lets not mislead the new forum members by citing rare occasions as the norm.

 

So the new bracket from ATI looks like the MMS unit??

VR

 

its too bad that a handful of people have to hijack every thread and ruin this forum.

 

Shinobi'sZ,

You should not try to mislead anyone either. . .the stock kit is good for 450-500rwhp. Any more than this and you will be pushing stock interals beyond their capabilities. Also, if you take a poll, I suspect you will find many people, like myself, who have had a positive experience with ATI? You start the other thread (poll) and I will participate.

IMHO, the real downside to the ATI kit is the intercoolers DO NOT cool as quickly as Andy's SIC. As a result, in spirited runs the temps will climb quickly and timing will be pulled. . .resulting in lost power. Oh, one other thing, laying down the radiator and using the stock fans makes Andy's kit 100% better (the ATI single fan is one of the worst things EVER), again, IMHO.

I am not trying to mislead new members. In my previous post, I even wrote, "I can say, without a doubt, I will purchase all of my future Vette mods from him (Andy). His setup, especially the reconfigured tubing, single intercooler and the ability to maintain the stock fan is perfect. As for ease of install, I will have to wait and see what the Vettemaster decides".

Additionally, I did have a problem with the idler pulley seizing up (which was also indicated in my previous post). To this point you are correct. ATI rushed their original setup to market and they should have been aware of the idler pulley problems. Then instead of fixing the problem by utilizing a larger idler, they simply changed the bearings (which also locked up on many people). This much is true, the R&D by Andy and other forum vendors should always be appreciated and supported.

Now, back to the question at hand, anyone have pics of the ATI setup? If no, please post. I personally would like to see the good, bad and ugly. Otherwise, I will see about getting pics this weekend.
