turbo or procharger?
back to the original post the STS kit is very good. yes it is just as easy to install as all other kits. my car on 9psi makes 500rwhp through an A4. a D-1 procharger would not make any more power at that psi. great daily driver, i dont have the car lowered and i have no clearance issues.
good luck on your decision .
p.s. Checkout the stickies in this section of the forum to help you out...

Bashing is one thing, a flawed kit is another. I can sell a product just beacouse i like it, or i can be a honest guy and get you what you really want, something that wont nickle and dime you to death.
Im a fan of turbos as well, we do full turbo installs and custom kits, not just he ATI stuff. We put together a package for the average joe to buy and install him self, have little or no worries, it includes everything you need, sans a dyno run.
The rear mount kits run great, look at MajorSpray and his new TT setup, one of the few vettes that can wheelie like that.
In the end, its defiantly about the customer, i will not sell or push a product if i would not install it on my own car, plain and simple.

You can debate Pro's and Con's with each system if you needed to but alot of facts, pro's and con's can be found in the stickies which compare S/C and Turbo's so it's all about preference. You can't go wrong with ATI just as you can't go wrong with STS.
As far as STS oil system, it's meant to be a bolt-on kit so they designed a system that although not ideal works fine. Welding a bung anywhere would take away from the bolt on aspect of it. I run an STS and see more tha 6xxrwhp
on mild boost and have no complaints about it at all and have had no problems concerning the system. There are parts of the system that can be upgraded to make it better but that's true about any system really. One thing I do attribute to the STS being better at compared to other systems is it's cooling effect, simplicity of design, and audible enjoyment.If you go with ATI you'll be happy I'm sure. Just figure out before hand what it is your looking to get as some systems are cheaper to upgrade than others.

Oh and as far as preference is concerned...IMO the belt whine from a Procharger does want to make me shoot myself too! Sounds like bearings gone bad. But then again I know some people don't like the spool of a turbo so it's all what you like really.

Hopefully the new M/T 18's will help you out. Bob
So.....which to get. Depends what you want. Here's what I noticed after seeing/working on/driving both.
ATI Pros:
1. Nice compact design. Self oiling.
2. Great lower/mid-range HP gains.
3. Easy install overall
4. Tuning was no harder/easier than the turbo.
5. Much better ground clearance than the STS.
ATI Cons:
1. Damn belt has to be stupid tight and still slips a bit. Keying the crank is the option, but that's a pain.
2. Don't have info on the newer ones, but the older intercoolers suck (saw IAT's hit as high as 190
3. If the car's an auto, need to remove the trans cooler lines to the radiator to replace the belt.
4. The ATI uses a single electric fan. This is inadequate for southern areas. Need to add a fan for hot weather.
STS Pros:
1. Gets better fuel mileage when driving about town than the Procharger
2. Makes great upper RPM power
3. Scares the crap out of the "import crowd".
4. W/ a boost controller can flip a dial for more boost. No pully changes needed

STS Cons:
1. Harder to install.
2. A FMIC is a MUST. STS was smoking crack when they said it wasnt needed. Stock my IAT's were 140 degrees. So, add the FMIC to the cost.
3. Oil pump wiring is a pain and I ended soldering most of it.
4. Need to wrap the exhaust to get decent lower RPM boost.
5. Ended modding quite a good part of the kit from stock to fix inherent "defects". (Pipes for improved clearance, relays, etc).
Cost after all.....injectors, pump, upgraded valve springs, FMIC, tuning, etc is pretty comparablebetween the two systems. Unless you upgrade to the D1SC, power output is fairly even too.....just the SC is making power lower in the RPM range, which is a benefit for street driving.
Well, you'll hear both opinions....mostly that ATI is the next best thing to hardcore sex.
