E36//M3 ERT Supercharger



>
>I just want to pass along my experience with the ERT Vortech Supercharger.
>ERT installed what they call there racing supercharger setup last Monday.
>Basically, it is the same kit as the more common powerdyne supercharger,
but
>they use the Vortech unit which has oil lubed bearing and is gear driven.
>There kit includes larger injectors, different mass air flow sensor and
>computer chip.  I also had the bored out throttle body done for an
additional
>charge.
>
>ERT started the installation process by getting a base line dyno run.  I
have
>a home made cat back exhaust system that appeared to add a bit to what they
>normally see for a stock M3.  The dyno came in at 210.1 max power and 199.2
>max torque.  I left in a rental car to play in Delaware while ERT installed
>the kit over the next 2 days.  There shop is very nice and the people are
>friendly, enthusiastic and seem to know what they are talking about.  I had
a
>bit of trouble just leaving my car with them, because for the last 10+
years
>I have done all the mechanical work on my race and street cars.  I was not
>disappointed.  The quality and attention to detail they demonstrated was
very
>satisfying!
>
>I arrived back the next day as they were finishing up the car and getting
>ready to make another dyno run.  Unfortunately, the weather was not the
best
>for high performance engines.  The temperature was 20 degrees hotter than
the
>base line dyno run and the humidity was at least 90%.  The final dyno run
>came out at 297.2 max power and 240.0 max torque.  Not bad!
>
>I finally got hold of the car and proceeded home in bumper to bumper rush
>hour traffic.  The temperature was at 95 degrees and the same humidity as
>mentioned before.  Certainly not the best conditions to enjoy a new toy.
ERT
>wanted me to put a 100 miles on before stressing the car to much.  No
>problem.  While in the traffic I experienced a miss fire and the check
engine
>light came on.  The miss fire disappeared immediately (I wasn't even sure
it
>did since it was over so fast).  The check engine light went off a little
>while later.  After a hundred miles I started to exercise the car.  The car
>definitely felt faster, but not as fast as my old fast car, a twin turbo
RX7.
> I spoke to ERT the next day about the slight glitch I seemed to have had
and
>they said that I was performing the shake down drive that they usually do
(I
>did rush them at pick up time because I wanted to head home) and for me to
>let them know if the problem comes back.  They also suggested I go out and
>run the thing hard to red line.  Well, that I did.  The car just kept
getting
>faster and faster.  The power if very linear and there is plenty of it.
The
>7 thousand red line is very nice as well.  I now think the car is as fast
as
>my old RX7 and more fun to drive.  My RX7 had all the performance mods
>(computer, bigger intercooler, etc)
>
>I will get the car on the track soon and let you know how it does.  The
>driveability did not change a bit that I can tell.  When driving around
>normally the car feels exactly the same.  Floor it, and the excitement
>begins.  I would highly recommend ERT and there Vortech supercharger kit!
>The quality and looks of the kit are superb!
