Looking at the graph dyno graph below some may focus their attention on the
overall peak numbers seen at the bottom of the sheet. You really need to focus
on different points of the graph to get the complete feel of what the system is
actually doing for the car and not an overall peak number.
You will notice at 3460 that the BR catback re-gains the ground that it lost
down low where the boost was substantially lower with the BR system until that
point. From that point forward the BR catback pulled ahead and never looked
back.
If you look at around 3800 where the huge dip was from the factory... our
system fixed that dip and gained 9hp and 11ft trq.
At 4700 you see where the A/F with the BR catback starts to richen up running
A/F ratios at 11.2 and 10.7 by the end of the pull.
Again at 5500rpm you will notice a gain of 12hp and 11ft trq. That was the
most substantial gain seen with the addition of our catback.
Where the boost fell off to 9.6psi about 400rpm before the dyno pull ended
our system allowed the car to actually breathe and hold 1.2 more psi at 6250.
You also notice after looking at the overall outcome how much the power curve
was actually cleaned up.
