There are a lot of factors to consider when talking about e.t.'s Weather, barometric pressure, altitude, track condition, driver, etc... all play a factor in the cars performance. Up where I live, there were alcohol funny cars that could only pull off 8.5 - 9 sec e.t.'s due to a virgin track and slightly higher altitude. These cars should have been in the low 6 to high 5 second range. So if your car runs 15's stock, it doesn't necessarily mean its slow.
