Run#2 Is my baseline - silencer removed with K&N 0945 filter, all else stock.
Run#3 added Paul’s High Performance air intake (sock on), all else stock.
Run#5 changed the exhaust to a stock 01 catback, keeping Paul’s intake.
Max Numbers:
Run#2 – 378.0 HP, 383.0 TQ
Run#3 – 385.7 HP, 382.3 TQ
Run#5 – 387.4 HP, 377.3 TQ
All runs were on the same dyno with the same operator at 5600’ above sea level. SAE corrected. Two runs were done each time with the ‘cooler’ (better) results used for the comparison. The battery was not disconnected but I waited a week between each set of runs to give time for the car’s computer to recognize (?) the changes in equipment. A large shop fan was on at all times but no heroic measures (ice bags on intake) were used in order to get fair comparisons. I do not work for Paul’s or any other manufacturer. All runs were done between 3000 to 4000 miles on clock. I used Paul’s intake instead of those that have the filter in the fender well because in dusty New Mexico, they are a PITA to check.
Chart #1 compares no silencer with K&N to Paul’s air intake.
Chart #2 compares the 03 stock catback to the 01 stock catback.
Chart #3 compares no silencer with K&N to Paul’s air intake with 01 catback.
Results were not what I expected. Street power (low-mid range torque) was substituted for high-end horsepower. Adding Paul’s intake gained an average of 1 HP and 1 TQ. Putting on the 01 catback lost an average of 1.4 HP and 2.9 TQ. From my baseline to adding Paul’s intake with the 01 catback lost an average of .3 HP and 1.8 TQ.
Although dissatisfied with performance gains, the car sounds great. Paul’s intake gives a low-pitched flying saucer effect (sounds better than this description) while the 01 catback gives the throaty muscle car sound without being obnoxious. Conversations can be had without shouting. I can feel the slight loss in midrange and the car is quicker after 5000 RPM.
My personal opinion is that when adding equipment you also have to add a chip to reflect these changes. The stock ECU will recognize changes in temperature, altitude, throttle position, driving habits etc but will ignore equipment changes and possibly make things worse. Then there is the problem that by adding a chip, one could void the warranty.
Anyway, I just wanted to post my results of making simple additions. Yesterday, I disconnected the battery for 15 minutes and will dyno the car again in a week to see if the results will change. I am disappointed in the outcome and disappointed that Paul has not returned my fax and 5 phone calls to discuss the numbers.
