took the snake out of its cage today and sank the fangs deep. i maxed out my speedometer at 200 MPH in 5th gear. i was pullin somewhere around 5,750 rpm's on my tachometer the last time i looked at it. the GPS i had sittin on my dash recorded a "MAX SPEED" of 198 mph (see pic below). to see a much better version of the pic i have included below just click on this link here >>> enlarged GPS pic <<<
i think the discrepancy between my speedometer and my GPS is due to tire slip on the pavement. kind of hard for me to tell though because the stock POS michellin tires started to wander pretty bad once i surpassed 190 mph....... but that might of had something to do with the two blown ACR shocks i have in the front of my car. bottom line is....... this is all she had in her because i kept my foot in it for 1 mile at this speed and there was just no more acceleration left to be had.
the road i threw down on resides at a static elevation of 1,370 feet above sea level. the air temp was 85 degrees and the humidity was at 20%. i am not sure what the corrected altitude was based on the barometric pressure but my guess is that it was close to double the static altitude. so this would put the density altitude of the air at 2,740 feet above sea level. the road i do my high speed testing on is perfectly flat and level with no elevation changes like a downhill whatsoever. there was a 10 mph crosswind blowing on my drivers side door. i had my windows up and my mirrors folded in. at about 180 mph my passenger side window popped out of its socket.
obviously on a road closer to sea level i would have been utilizing more of the power i have and would more than likely have hit 200 mph on the GPS. i will take my snake back to this same spot next winter when the air temp is colder and try again. with a 55 degree air temp i think i can hit 200 mph on gps
