(Graph shows TEST3 Vs TEST2)
TEST 3 figure achieved was 352.3bhp @ Flywheel with 441.1Nm (325.4 lb ft) torque
TEST 3 – As Per TEST2 plus Changed Panel Filter – Comments
TEST 3 +34.1bhp +24.37lbft (peak) over Base Line
TEST 3 + 8.8bhp + 2.32lbft (peak) over TEST2
First off, we managed to push past 350bhp without any modification specific re-mapping and while still only using Optimax.
Top line figures increased for bhp quite significantly, while the increase in torque was fairly negligible.
Looking at the graph (which overlays TEST2 against TEST3 figures) shows a some what more meaningful comparison though.
As you can see, early on in the rev range (up to 3200rpm), the power saw increases of circa 10bhp and torque increases of 15lbft together with a stable increase (against TEST2) again in both power and torque above 4000rpm to past 7000 rpm. Again, this further underlines the fact that peak figures do not tell the whole story and with these kinds of increases (especially low down and higher in the rev range), the results were very pleasing from such a simple modification.
Overall the results showed that this specific uprated panel filter worked well to produce an impressive result.
Please note: No changes were made to the mapping from the Base Line. AFR’s remained virtually the same (certainly within tolerances) and boost levels remained constant and were controlled.
