Hello to all,

I've been "lurking" on the list for a while now.  Until this point, I
have not felt the need nor
had the time to reply to the numerous posts on the list. I believe the
list deserves to know the
facts about our VR6 Supercharger Kit.

1. Why has it taken AMS so long to release the kit?
    The reason it has taken so long is that we at AMS wamt to provide
you with a quality
    It takes time to produce a quality product and the release of the
kit too soon would have
resulted in many revisions
    and customer dissatisfaction.
2. What about O2A transmission problems?
    -None of the test vehicles have experienced any problems with
vigorous driving and
    numerous dyno tests.
    -Power is linear with the supercharger therefore there is not a
surge of torque
    upon the transmission.
    -As we all know, abuse breaks transmissions. Shifting hard does not
make your car
    go faster. Supercharged or not, any transmission is vulnerable if it
gets abused.

3. Do you need a Quaife Differential?
    -Running a supercharger on the VR6 does not require a Quaife
    -None of the test vehicles have a Quaife installed.
    -A Quaife Differential is a nice edition even for a stock

4. What about the MAF?
    -In the early stages the MAF was removed, but through testing we
found that
    driveability was compromised, therefore the MAF was retained.

5. What kind of belt comes with the kit?
    -A 7-ribbed belt does fit and is included with kit.
    -The 6-ribbed belt slipped and was not feasible.
    -Replacement belts are available.

6. What about heat?
   -Engine coolant and oil temperatures are within normal operating

7. What is the true horsepower output of the kit?
    -It is possible(as shown below) to gain 100 hp from the kit, without
any modifications
other than an aftermarket exhaust.

8. Is the air conditioning retained?
    -Yes, the air conditioning is retained and operation is not

9. Is AMS in it for just the money?
    -Profits are an obvious motivation.
    -We are all VW enthusiasts just like you.
    -We strive to develop reliable parts that increase performance and
your overall driving

10. How long does it take to install the kit?
    -Installation for first time installer is approximately 10 hrs.
    -Complete step-by-step instructions with illustrations are included
as part of the kit.

11. How much does the kit cost?
    -The price of the kit is $3775.00. U.S.

12. When will the kits be available?
    -The kit is currently available for 96 and up Golfs and Jettas.

I hope this post will help clarify some of the questions and concerns
about our VR6
Supercharger System.  If anyone has any
further questions, please feel free to post to the list or e-mail me

Best Regards to all,

Well I have had my supercharger for around 3-4 weeks now and here
are some of my observations:

    1.  Gas mileage is not affected as long as you stay of the boost.
    2.  Even though it is cold here (Az.) I still haven't got the oil
        to hit 210 yet.  I am sure that will change once summer rolls
    3.  Maintanence is very easy (tightening the belt). I have only
        done it once on account of the 400 mile drive right after
        install.  Once you figure it out it takes about 5-10 min. to
        do it right.
    4.  Even though I have tried to modify the back of the low beam
        Hella, the blower will still make contact with it (not a
        good thing).  Do plan on changing your light system if you
        want the charger and you have DE's.
    5.  First and second gear are a waste at the racetrack.  Ross
        Stuart and I did the street car drag thing last night and I
        did totally crappy.  My first run was a 14.9 at 93 mph.  As
        soon as I saw Ross launch I stabbed it and making boost in
        first gear is another bad thing. I looked at my tach and it
        was bouncing off the rev. limiter so then I shifted and it
        happened in second as well.  By the time I had any traction
        Ross had me by about 8-10 lengths.  Boy, did I start to reel
        him in.  He turned his fastest run yet at 15.1 and I barely
        beat him.  Pretty embarassing.
             My second (and last due to there was 220 street cars,
        about a dozen bikes and around 25 race cars) race went a
        little better but still lousy.  I tried to take it a little
        more easy of the line and still burned out like crazy.  I
        pulled a 14.7 at 100 mph.  Ross got a 15.0 on that run.
        If you want to dragrace with a blower you better have a set
        of good slicks and plenty of practice trying to launch that
             I now know this car is capable of sub. 14 sec runs
        because on the way to get some drinks after the races an
        Eclipse GS-T got next to me on the I60. From the top of
        second and almost all through third we were dead even.
        (Ross it was the white one) He said he pulled a 13.91 at
        102 mph.  I didn't see him do that but his car was verry
   6.   The sound (or sounds). Nothing much to say about that
        except it is sweeeet.  Everyone turns their heads when you
        drive by.
   7.   The install is very clean. No goofy looking mounts or weird
        zip-ties.  Looks very oem except mine is polished along w/
        powder-coated and polished manifold.

Thats all I can think of right now.  If you have the $$$ (about $4500
of it, including the install) go ahead and do it.  Now I know this
list is pretty biased towards ND but AMS has a great system so don't
be afraid of comparing the two systems. If that system is ever finished.

Doug at AMS said they working on cams and intercooler for their system
and should be ready around spring.

Hello Christ.

I am looking for a AMS kit, somebody tool me about...The only tough part is
machining the AC pulley. The kit requires going to a single face belt, the
OEM is dual. The only thing the rides the back side of the belt is the AC
pulley so it must be machined smooth.
Do you made this modification on your car, it is working good any way.

My AMS SC kit took me quite a while (11 + hrs) but I didn't have the benefit
of a lift or an ideal install environment.

I'm hitting 10 psi around peak rpms and I have 97k on my car with no other
engine mods except for a Turn 2 lower front mount.  These things are a blast
and pretty much once you get them on and running right you don't have to do
anything but change your oil as you normally would.

An example of what you can do with this kit.....

Shelli spotted a very sweet black Audi TT hardtop on the way home from
Graceland and he wanted to play.  Unfortunately she didn't have any faith in
the GTI because she asked me if I was ready to get my butt whipped finally.
He was eager to see what he could do against me because he came right up
next to me and paced me until I stepped on it.  We were going about 70 and I
could have easily downshifted to 3rd but I left it in 4th and stepped on it.
Not even a couple seconds later I saw him shift so knew that he had the
boost really pumping when we took off.  We were dead even for those two
seconds.......but I was just starting to make some boost : )  Once my rpms
got a little higher and the boost was coming strong I left him VERY FAST.
I was disapointed that he couldn't keep up a little better but the look on
Shelli's face cheered me up.  She couldn't believe that I just spanked that
very expensive and very beautiful car.

You have the AMS and Eurotech kits to pick from if you want a Vortech
Supercharger based system, these are basically the same kit.  The other
system is the Z-Engineering Supercharger system which is easier to install
but makes less power.
Do not bother with getting a Eurotech system.  They have and are giving
anyone wanting one WAY too many problems that I won't get into on here.  AMS
(kit I have) is basically the same as the Eurotech kit and was the original
manufacturer of a Vortech based kit but their software is a bit dated and
could be improved on.  I have had no problems with their customer service
but have not had to deal with them much.  They do not seem to be interested
in updating the software or making any further upgrades to the kit.  They
almost seem to not even care about selling it.  As far as the Z-Engineering
charger goes you get a easy to install kit that has had 3 generations of
updates.  The updates are a good and bad thing.  They improved the kit but
were also done because of many problems that the kits were having.  They put
out less power but don't cost any less.

The rest is up to you to decide on how much power you will be happy with and
if it will keep you happy.  Don't get me wrong about the AMS kit.  There are
still things that you can do if you want even more power and the regular
software it comes with is ok.  I'm sure that the Z-kit will also be getting
power upgrades as well but I don't think that the charger they use will ever
be able to compare with the Vortech charger being used in the AMS and
Eurotech kits.

The AMS kit does come with a CARB #.
