Vortech or Ati
i would go with the ati. I am bias though because i own a ati. The intercooler setup makes it all the better. More boost equals more power. As far as cost i don't know, i'm installing mine myself. As far as reliability i've heard great things about ati and vortech. ati's service on the other hand has not had such a high rep. choose what u want though, its your car and your money. But my vote goes for ATI.

Last year before I decide to go 383 I did some research about it and both are very popular brands but in the end ATI wins.....

i'll make this very simple:
i feel vortech has better quality/service than ATI, but with a thirdgen and our long runner intake....on pump gas and stock timing you will MAKE MORE POWER with an ATI than you will a Vortech because of the intercooler
there are numerous people who have taken stock motors into the 12s with ATI's 9psi kit and i've *heard* of 1 person doing that with a vortech but when i looked into it i wasn't getting responses so i think it was a lie
anything else?
or...ATI is more expensive but its worth it in the end

I just got my ATI procharger installed. Customer support was less than par but they did help me in everything I needed.. Turns out the SC kit isn't really made for the T/A so when you install the pipes, get ready to do some cutting and maybe some custom work. I actually ordered pipes from ATI and had them send me pipes that were already included in the kit and used those to get around the body and fascia moldings under the nose of the firebird. Hopefully I'll snap a roll of film and show ya'll what I came up with.. Today I got it up and running right and I'm running 7 lbs of boost and it's running a little richer than I thought it would but it's pulling like a mother. I love it.. I haven't heard much about the vortechs but I went with the ATI cause so many people on here recommend it.
Installation time for me isn't very accurate seeing that I started installation in July and I just finished and it's December. Of course I also did several other things to my motor while it was down. Ported and polished the heads and intake, valve job, new timing chain and gears, oil pan gasket, driveshaft loop, raised the car to stock as well as find places to relocate the cruise control and horn. Everything FINALLY fit in there but it's tight and not much fun but now that it's pretty much over, I'm really happy with it. I'd say if I had worked straight 24/7 for a full week, I could had the SC in there and running.. The instructions say you gotta do some cutting of pipes and fuel lines but since they wrote that, it's changed and they've included fittings that let you just screw them into the existing fuel lines.. Makes it real easy. If you have an ATI and a T/A let me know if you need any help.

we sell both but ATI outsells vortech 10 to 1 because, i believe it is the options and price.

When researching this over one year ago, I looked at Vortech and ATI as a replacement for my Paxton SN2000. I chose Vortech, BUT before I committed to buying it, ATI introduced their new self-contained superchargers. I called Vortech and asked if they had plans for their own self-contained units. I was told no. I changed my mind that day and went with a D1SC from ATI. One year later, the D1SC is going strong and I do not regret the decision I made.

that is another reason I sell more ATI prochargers, when I tell my customers about the self contained option and the fact that they won't have to poke a return hole in thier oil pan, its a big seller

the oil return line needs to be nearly straight up and down otherwise it may not drain properly (we have seen this) and excessive oil return pressure results in a smoky blower ( the oil pushes past the seals) rerouting the return line to the pass side of the engine, can result in a more horizontal return line. same applies to returning to a valve cover, on turbos and blowers.

can u really tap into the fuel pump block off plate? how much easier is this than going threw the oil pan? can u do that when the blower is mounted on the drivers side? thanks for the help

a73camaro,
routing the oil line to the fuel block off plate will work if your blower is mounted to the pass. side of the engine. but the ATI's for the third gen are mounted on the drivers side, so to route the oil line to the other side of the engine would not be practical, but i'm not saying that it wouldn't work.

If the P1SC and D1SC can both support 12-15 pounds of boost, which would be better for a mostly street driven car? From what I can read in the ATI literature, it looks like the D1SC, with the helix impeller, is better for higher rpm power, but loses a little power at lower rpms. Does it really seem noticable?
I am planning on building either a 355 or 383 with around 8.5:1 compression and suitable "blower" grind cam and MiniRam II. The car is a manual tranny and I plan on keeping it that way. Just wondering if there is that much of a difference between the 2 on the street? If not, I would probably go the D1SC route for the higher rpm/power potential.

i ran my vortech oil return line to the fuel pump block off plate
and yes it did cause the blower to fill with oil and cause it to smoke i tride to give it the straitest pipe to it but still did not work well enuff for me so i just taped to oil pan and have had no problems sence i also added a small screen in line just in case a
bearing goes bad

If you want to buy a supercharger and run low 13's or high 12's buy a Procharger. If you want the car to jump right into the 12's and be a few mods away from the 11's go vortech. I know people are going to start refering to classes like NMRA pro5.0, but that is not what we are doing with our cars(obviously). Just look at some of the faster cars on this board and others. Procharger cars outnumber Vortech cars 10 to 1, but the fastest cars are equiped with a Vortech. Start a poll on this board, and ask the TPI cars for 1/4 mile times with Procharger and with Vortech.
