·Hi everyone,
I would like to get opinions on my first ever dyno that I did at the North East meet a few weeks ago. I'm wondering if I should be concerned and I figured this would be the best place to ask. A pic of my dyno is below. Here are the details of the dyno:
Outside Temp.= ~70 degrees F
Humidity = 90%
No fan on intercooler for any of the runs (argh!).
Did NOT ice intake.
Limited my boost to 1.2 kg/cm2 (~17 psi). Peak boost hit 1.19 kg/cm2.
TTC
RMM downpipe
Tanabe G-power Exhaust
Blitz DSBC
K&N cone intake
Stock plugs @stock gap (w/~6K miles)
EGR mod.
Pump gas (93 octane)
Car cooled for ~4 hours before dynoing.
Only about 1 minute between the first and second runs. About 3 minutes between 2nd and 3rd run.
The track didn't have race gas so I didn't want to boost past 17psi (set my DSBC at the lowest possible setting). After dynoing, I also found out by other spectators that they didn't place the fan in front of the intercooler--they had it in front of the radiator! This would explain the gradual drop in power from the first to third runs--heat soak killed me! Anyway, now that I have had time to think about the results, I'm wondering if I should be concerned. Shouldn't I have dynoed around 400hp +/-10hp? I realize that if I turned up the boost to ~19psi I could have gotten better numbers but I didn't want to risk detonation--I'm glad I didn't after finding out they didn't have the fan in front of the intercooler! So, I guess my question is: is ~370hp/tq acceptable at 17psi? Any other comments you might have would be great. Thanks guys.
