BWoody Jeep CAI vs DUB AIR:
I received my BWoody CAI yesterday and installed it immediately thereafter. Even with a broken pinky finger it was cake to put on, I think it took me a half hour, tops. Anyway, after driving around for a few miles the Ass-o-meter said throttle response was greatly improved and it felt stronger everywhere--especially low end/midrange. In search of concrete proof I hit the dyno today, and was somewhat shocked by the results.
Here are the spreadsheets showing the gains going from the DUB (peak of 366/370rw SAE 4th gear) to the BWoody (370/378rw SAE 4th gear). The gains at peak rwhp/rwtq were 4rw/8rw but as you can see by looking at the spreadsheet comparison below, the avg gains are HUGE and literally across the entire rpm band. For instance, from 4300-4600rpm the BWoody holds a 10-12rwhp advantage, and from 3400-4600rpm the Bwoody has a 10-15rwtq advantage. The BWoody simply outperformed the DUB across the board (there were absolutely no data points where the dub made more power or torque) which will be much easier to see when the comparison graph is posted. Gains like this from a CAI, let alone vs. another aftermarket CAI, are fairly astonishing to me. Nice work Mike/Gregg.
The only other variable that changed since the DUB dyno was the addition of GSM phenolics which won't add power to a cool motor. Coolant temps for all runs (both dub and bwoody) were between 190-200F, with oil temps at 195-210F.
Additionally, there was only a .01 variance in correction factor used (1.01 vs. 1.02) between the two tests.
A spreadsheet including calculated peaks and gains, of the DUB (left) vs. BWoody (right) both corrected, same gear, same dyno, same vehicle, same operator.
