first hello to everybody and please forget my english
here my final result with sikky header 376 HP & 347.1 TQ 21 degree outside no humidity at all (perfect day) on a dynojet dyno
not impress at all
my car have 15000 km
so after 3 different dyno the gain is not as much as everybody who pass on the dyno at sikky place
my base run was 367 with all the mod except the headers
my best run was 385 after resetting the ecu
today on a different dyno my best run was 376hp and the second one was 367 also !!!!!!
so ask me if i am impress ?? not at all
the only good thing is the sound (for me)
next step will be on a mustang dyno my result will be aprox 6-8 % less
p.s everything was sae 5 corrected
DID YOU SEE MY TQ IS 347.1 SAME AS POEPLE WHO HAVE 413 & 416 HP ??????????????????????
I THINK THE DYNAPACK IS NOT ACCURATE (CAUSING BY THE WHEEL NOT ON THE CAR) LESS POWERTRAIN LOSS
THAT POSSIBLE !!
I don't want to come off and sound like a know it all, because I am definitly not a tuner or mechanic, but your dyno testing method does not strike me as being right man. You also can't compare results from one dyno to another as they are all a bit different even if they are the same make/model.
Looking at the chart you posted it doesn't even make sense to me.
1. Run 062 on 8/18/10 3:13:56pm resulting in 367hp and 342tq
2. Run 061 on 8/18/10 3:08:52pm resulting in 376.5hp and 347.1tq
Why are the two runs only minutes apart for a baseline/results comparison?
And finally, considering we now have 3 people with 40+whp gains and I've confirmed on a dynojet as well as the dynapak it's safe to say you are fine and you do have the additional hp that you are worried that you do not have. Just chill man and enjoy the headers.
