Cold weather = Dyno time!
Brrrr!!! It's cold outside! Then I thought ... its perfect weather to hit the Dyno for an update run on my header install this past summer!
I dyno'd my car earlier this year in January when it was ~65 degrees which netted me about 198.4 HP/127 TQ to the wheels. I installed the J's SPL header around June/July and wanted to wait till weather conditions were similar to the baseline run before to get a more accurate gain #. So, I visited DynoComp this morning for a quick dyno before heading to work.
Well, here are the results ...
Dyno with HP/TQ #s :
Dyno with HP/AF #s :
202.8 HP/134 TQ (+4.4HP/+7ft-lbs TQ peak) without any tuning. But that's not the good part ... there were gains everywhere under the curve! In some places (e.g. just past 6K), I picked up almost +14 HP and +12 TQ but most gains were in VTEC range. Quite happy with the result. I'm sure with tuning I can lean out the A/F ratio to pick up some more peak horses but for a straight bolt on and no tuning, its pretty good numbers.
Some other pictures I took while I was there :

to DynoComp. Awesome shop to work with. Great group of guys and their shop car consistently place in the top 1-2 in time attack runs on local tracks.
Specifics on the car/conditions :
- Comptech Intake
- Megan Racing Test Pipe
- J's SPL Header (only addition since Baseline Run)
- J's Racing 60RS
- '03 OEM ECU
- About 68K miles on the odo (about 4.5K more miles since Baseline Run)
- Temp conditions were about 56F at 10:30 this morning
Here's my post on my original run earlier this year -> Baseline Run

Edit : Corrected miscalculation of peak TQ gain #s.

j/k Merv. I haven't dyno'd since I put on the test pipe.
Was hoping to milk that excuse for as long as I could!

Awesome...I'm planning to dyno soon to get a baseline now that I'm stock again (except for the 4.57's). But I guess I'll do it back in CA so I can keep going to the same place after every mod.
Anyway,
Anyway,
