Itis, Honestly, from my recollection of that day, at the hit, your car seemed a little stressed out as far as RPM's. You just might be going through the converter as mentioned above. The car almost sounded Funny car-ish as far as RPM's.
Also, remember the weather was a bit sticky and no oxygen even though it wasn't too HOT,HOT as far as temps. I don't know what the Barometer readings were.
