* Note: The air/fuel ratio indicated that a lack of fuel limited the power output.
The torque peak is moved up in the
power band and is still higher at the stock peak and
climbing. Our exhaust helps to fill in the major dips in
the torque curve just before 3000rpm and at 4500rpm,
making for a quicker car that feels smoother (slower?).
There is a gain in horsepower before 4000rpm however
this is somewhat minimized due to the 2.5" diameter
cat-back. This affects the low end torque as well. The
larger size was required since the car now has a Stage
II Head package (140+whp, sorry no graphs yet). Keep in
mind that the car was running quite lean and is waiting
for a fuel pump, RRFPR, and a proper intake. It will
also get a stand-alone engine management shortly. More
info to follow.
Stay tuned for more test results...
