Did you change out any Internals, or have plans for same in the future? Seems like alot of power for a stock bottom end. Nonetheless, it's a example of why the ATI is so popular, it's the King of hp. What are your torque number, and could you post a dyno?
Good Luck with your setup, and great deal BTW, your very fortunate.

Personally I'm of the opinion that the Z06 bottom end will handle 600rwhp w/o problem IF it's properly tuned and has enough fuel to support the horsepower, I've put 5k miles on the combo and beat the CRAP out of it, but many people tell me I'll blow the pistons and need a forged bottom end.
We'll see. Either way, I love the car as it is, I'll pay for the bottom end when needed.
Will attach the dyno, have posted it before...

Care to elaborate??? I have been told by many wiser men then myself to avoid the ATI at all costs on the Z as well..... I was just curious as to what your problems consisted of. This puzzles me, because kit for kit, car for car, I would have to say that ATI is the #1 SC Company out there today
I am in a toss up between the Vortech and the Magnacharger..... Like the torque and the looks of the Mag, and like the all out power and intercooler of the Vortech..... Decisions Decisions!!
ATI's product is decent, at best. Luckily I was local to MMS and A&A and they have made several great improvments to the product. As all modders know, cars are expensive, much like a money pit. Well, this blower in itself was a money pit, not to mention all the other mods I would like to be doing in addition to being blown. i had tons of belt slippage, after trying several "solutions", the sound it made when it slipped was horrible, felt like my car Z06 was a 1984 toyota pickup who's belts were slipping. anyway i gave up on it and went to the nitrous. If i were to go forced ind. again -not likely- I would go with the vortech or probably the turbotech twin turbo if theyd give me some up front pricing. the magnacharger is for a stock motor, and as we all know - once u have some power, u want more. mag. doesnt allow for much increase. at least with vortech you are intercooled and can raise boost to match engine capability. belt slip can still happen with any blower though. i love nitrous cuz i can spray a stock motor, a h/c motor, upjet and do a forged stroker with out problems, ya theres risk but i have set it up safe, theres risk with all serious mods. good luck

There are certainly different opinions on the ATI but after experiencing the belt slippage myself, I have all of the pulleys replaced with 8 ribs and have had no slippage since. ATI made a number of improvements to the D1SC over the last 2 years and I think you'll find it is one of the better blowers for our Z on the market today. The twin intercoolers have kept my engine temps amazingly low..... even during roadracing sessions.

word. i feel pretty confident if i would have stuck with it i could have eliminated most problems. i just didnt have the time or money. plus the ls6 has pretty high cr stock, it just makes sense to spray it!! if i had the $$ to build a low cr motor, then it would make sense to throw the FI on it
i want the deal Dozer42 got and I would never look back. There Is the vender that we can't mention that dose the Ati D1SC supercharger for $8500 and was thinking about taking my car There. but he has only done 2 installs though He clam's they were great succses. Is there any vender from the forum that has more experenced in the mid west with that kind of price or better?

The stock internals will take a max of 6#'s of boost with good fuel and conservative timing, up tp 9 if you add an intercooler. At (roughly) 20 RWHP for each pound of boost that means with excellent tuning and no changes except the blower you can add 180 RWHP without forged internals.
That said a blower motor with hyperpathetic pistons is a time bomb, and it will go off one day. Any detonation, for any reason, with that high compression and they will go bang. The detonation could be caused by something as simple as a bad tank of gas. When people ask me about building a blower car knowing I have raced (and destroyed) blower motors in the past, my standing advise is to avoid any power adder (including nitrous or turbo) until/unless you have the money and time for a rebuild. If you have both then go have fun
About ATI, they have a rep for making a pretty good blower but poor customer service, which is why I went with Vortech. I have had 3 Vortech blowers with zero problems. Belt slippage is a problem with any blower and I recommend an 8 rib system to keep it to a minimum. I went with cog drive for my current system as it produces 23#'s of boost, no rib system can handle that much force

Great setup, tell me some stories.

Les, since you're running at 23lbs of boost and using a cog drive, I assume your talking about your drag car. What type is it, what CR and is the cog drive too difficult to use around town. Just curious. My 8rib system is doing fine but I always wondered how stiff the cog drive would be off the track. Thanks buddy!
just installed the magnacharger...with a vararam...these are the only mods...and no i didnt dyno 391 rear wheel horse power or torque....like z06dust...it was more like 444 rear wheel torque...and 443.2 rwhp...not bad???? it is absolutely incredible...with only 5.5 pounds of boost....not harmful for the motor....94 octane gas is a must....i absolutely love the low end torque...
From what I have seen, heard and researched, out of the three, I would pick the Vortech.
I've heard of a lot of problems with ATI, but then again, I've heard a lot of tuners that have made great improvemnts on ATI's package. ATI customer service is another story however.
I've heard personal experiences with Vortech, and they say that their customer service is superb. I haven't heard of any problems with this setup, except that it's more difficult to install. They have a good history with other cars too, so they've had experience to make improvements.
Magnuson is a very close second place for me, as it gives you the torque at low RPM's for the kick-in-the-pants feel. Neither centrifugal SC (Vortech and ATI) give you the low-rpm torque. The centrifugals are too peaky - that is the horsepower is only at the higher rpm's, whereas the Magnuson's dynograph is flatter, therefore more HP and TQ at the lower end. Only problem with Magnuson, is that it has no after/intercooler, so it introduces heat into the engine (which robs it of power and is stressful on the engine). However, I've heard that Magnsuon is planning on an intercooler in the future sometime.
Now, if you threw in H/C, nitrious, or turbo into the mix, I would pick a turbo because it has a good hp & torque curve, intercoolers to reduce heat induction, and has a cool factor to it. In fact, I am having a twin turbo installed in mine in the beginning of July. For the H/C, I don't want a lumpy ride, like that of the 60's cars (our Z's are modern cars). And nitrous just makes me a little nervous, probably due to inexperience with those setups, although I've heard people swear that it's the best power adder.

anyway i gave up on it and went to the nitrous. If i were to go forced ind. again -not likely- I would go with the vortech or probably the turbotech twin turbo if theyd give me some up front pricing. the magnacharger is for a stock motor, and as we all know - once u have some power, u want more. mag. doesnt allow for much increase. at least with vortech you are intercooled and can raise boost to match engine capability. belt slip can still happen with any blower though. i love nitrous cuz i can spray a stock motor, a h/c motor, upjet and do a forged stroker with out problems, ya theres risk but i have set it up safe, theres risk with all serious mods. good luck
