This is the second chart that I have and this is the non-smoothed version. This includes DYNORUN.002 which of course, looks slightly different from the other chart. You may also notice that the MAX horsepower went from 200.3 to 200.6 and the MAX torque went from 216.6 to 217.2. Not that they make a huge difference, but the lower numbers on the previous chart are from smoothing the curve. I apologize for the number of runs on this chart. This is the way they printed it and they swear that they do not have a PEP version...that's funny...look under the chart on the right side :-)

Anyway, here you can clearly see the jagged ripples in the NOS-run curves. These are what the tech thinks are caused by too warm of a spark plug. Again, he says that they run plugs as cold as 9's in Mustangs and I am running 6's. OR this could be caused by the jetting. Since I was running the .059 by-pass at the time, there may have been a minor fuel pressure problem at that point, especially since these were all made with 4th gear runs. See the "Fuel Pressure" section in my NOS Notes page to see what I am talking about.

I also have no idea what the big dip is at ~4200rpm in both the horsepower and torque curves of DYNORUN.004 (NOS). I think that the VRIS is opening/closing at 4250, which might have an impact on it. There are dips in the same location on .002 (also NOS run), although they are not as pronounced. Notice even in .003 (non-NOS run) that there are minor deviations also at ~4250... Whatever the dips are, it appears that they are built into the engine's powerband and are magnifyed by NOS or engine heat. Note that I have also noticed the 4200rpm dip in other Probe dynos.

DYNORUN.002 is the non-smoothed version of the same run on the other chart.
DYNORUN.003 is a non-NOS run about 5 minutes after run .002. The effects of a warm engine are clearly noticeable with a 2HP and 2.4ft-lbs less than on the fresh baseline run (.001)
DYNORUN.004 is a NOS run about 5 min. after run .003. Again, a warm engine costs 2HP and 5ft-lbs of torque. Notice that the NOS curves are almost identical, only the warm engine run shadows directly below the cooler engine run.
