New Dyno runs with Borla Catback & Tom's Filter 391rwhp
Guy made it to the dyno today at Rage Tek here in South Florida Dynojet 248c and below are the results.
Car: 2009 ISF 45k all stock except Tom's Panel Filter, and Borla Catback Exhaust
All graphs SAE smoothing 3 (In STD the car did over 400)
Pass 1&2
Were done back to back 1 minute apart right after a 35mile highway drive, and made no more then 15 minutes after arriving to the shop. Sport more and in F mode in 6 gear with AC off and traction control disabled.
Pass 3
Was done after a 16minute cool down in the same manor as runs 1 & 2
Pass 4
Was done 2 minutes after pass 3 without turning car off and you could feel the timing get pulled around 5200rpm's which i know cause i drove the car for all the passes.
Pass 5
Did another 10 minute cool down with the fans blowing away on the engine to back up my pass 3 to make sure it was not a fluke sure enough numbers matched and if you look at airfuel you can see how much richer the car gets when hotter vs cool down passes which results in a large hp decrease the peak tq is not affected since it happens at 5200rpms right where the peak tq is then both drop when the computer pulls the timing on the top end and the AF go rich.
Well looks as if this car needs a thermostat or better cooling possibly but i will be back on the dyno in a day or two with the SIkky Headers on to see how much more it will make time will tell.
Thanks

The higher the leaner and the lower the richer this car should be around 12.0-12.2 and it would gain great power but since this is no tune this is not in our hands but the OEM computers. I bet there is 20-25rwhp to be made "as seen above" on this car with a custom tune to fix the AF after 5200rpm and desensitize the timing setup so it does not retard.

Could not tell you did not dyno previous to install but i have another ISF that is stock maybe i will stick that on there and see what it does. Im sure there will be other ISFs to dyno here from S.FL after there header installs so will get more numbers up soon.
