This is what everyone wants
to see - the Dyno Charts
|
|
| |
The following
dyno chart quantify the changes that I have made
to the car's performance . Aside from these charts,
the backside test reveals that this car can leave
a serious grin on your face.

| Abbott
ECU Dyno results - Feb 2002. I considered
the performane from the Abbott ECU a moderate
increase in torques, but no increase in HP
over the stock rating. Unfortunately, it appears
as if they have tuned the chip to the SUPER
rich side to prevent potential lean-out at
high boost. You can see that the air/fuel
ratio actually goes off the chart a little
before 5000 rpm. Needless to say, this ECU
did not stay in the car. |

Stage 3 ECU Test June 6, 2002. Now,
this is more like what I expected from an
ECU upgrade. The SQR ECU has given a 50HP
increase at the wheels over the Abbott
ECU. Torque has also increased another
42 lbs/ft. Also, you can see that there is
less detonation. This is reflected in the
smoothness of the graph line. The Aquamist
system is working effectively to control detonation.

Stage 4 ECU Test January 22, 2003: I have
also added the new intake manifold and a high
pressure waste gate actcr. Horsepower is up
anther 22HP and torque has increased another
68 lb/ft to 370 lb/ft. If you presume approximately
13% transmission power loss from the flywheel
to the wheel, that would put the HP at 308
HP (SAE) and torque at 427 lb/ft. This isn't
too bad for a 2.3 liter engine on the stock
turbo, block, and head. |

Stage 5 / Custom ECU September 23, 2003 -
After the engine modifications (see engine
page), we contacted Frank at SQR to setup
some custom software to take advantage of
the new hardware, As you can see, the car
runs pretty nicely now! Judge for yourself.
While done on different runs, the max horsepower
(SAE) at the wheel was 291.6 and the maximum
torque (lb/ft) was 382.4 measured at the wheel.
Now, if you presume 12% transmission power
losses that would calculate to 331 HP and
434.5 torque. If I were to have changed to
intake from the naturally aspirated one that
I installed which tends to produce more torque,
then the horsepower number would probably
have come up some and torque down.
