A quick review of my '01 GTS project...
BEFORE
-> Factory headers, heat shields, cats.
-> Corsa cat-back with rear mufflers deleted.
-> Factory sills with factory insulation.
AFTER
-> Belanger headers, Dave's custom heat shields, Parts Rack R/T HF ceramic cats.
-> Dynomax mufflers from Belanger, 3" side exhaust from Belanger.
-> Autoform FRP sills, Dave's custom bottom venting, stock insulation trimmed to clear custom vents.
-> Parts Rack louvered vents in wheel wells.
Temperature measurement points were based on the maximum temperature in the area I was looking for, and is different before and after because the parts are different.
The measurements were taken after a 20 minute afternoon drive home. Exit car, shoot pics. Not even twisting the cap of a long neck postponed the data gathering.
So here's the data:
The before measurements:
The after measurements.
Like I said above, I moved the measurement point to suit the new parts. The shorter cats are right below the door hinge area, and not in the bulge of the sill like the OE cats.
An interesting note, as I guess my AC puked whatever freon it had in it while modding (AC always sucked, guess I know why now...), is that driving home yesterday with the windows up and the AC blowing warm air, it was really not that hot in the car.
Before, with the OE cats and at least some freon (blowing a little cold), you would bake in the car.
So while I wait for the R134A gauges I ordered from Amazon yesterday to arrive to charge the AC, I'm meanwhile going to call the project a complete success when it came to reducing temperatures both inside and outside of the car.
