Dyno results for TPIS LTs and RT HF cats Here's the scenario:
I dynoed my car yesterday to see the improvements from my install of TPIS LTs and a Random Tech x-pipe w/ cats. To my dismay the car actually made less power than previous dyno sessions.
First dyno session was a baseline pull: 305 hp 309 ft lbs
Second pull: added a twin flow intake 313 hp and 316 ft lbs
Second dyno session:
Pull one 323.1 and 322.6
Pull two 319.9 and 327.1
AF ratio: between 13.2 and 12.8
Changes included: Blackwing filter and Corsa Touring Catback
Third dyno session:
Pull one 320.29 and 335.25
Pull two 319.5 and 334.20
AF ratio:13.3 and 12.7
Changes include the addition of LTs, high flow cats, Taylor wires, and Bosch Platinum plugs
The very first pull of the third session is not listed because the dyno showed 179 hp. According to the dyno owner, the pick up was not reading through my wires. He changed plugs and tapped into the coil lead to get a more accurate reading.
The car is a '99 C5 Hardtop with 22000 miles
The car has been very responsive to all changes and would say with little doubt the LTs and cats increased the horsepower.
Does anyone have an explanation for this or had similar results?
Before you say something was wrong with the dyno, I had a freind who dynoed his stock '02 Camaro SS 345 horse immediately after me and it made 305 hp which should be pretty close.
