I have been consistently getting 0-60 times in the 4.6 to 4.8 sec range when in sport mode, but when I used track mode and the paddle shifters to control the shift points, I was able to get a 4.4 sec mark. Has anyone else been using track or sport mode with the paddle shifters with similar results?
The best I've got is 4.5, but I haven't tried with the paddle shifters, that was in sport automatic, will try with shifters tomorrow...The 8k miles is impressive...
The 8k miles are mostly highway, WI to IL, WI to TN, WI to CA. Not a lot of issues, but the Adaptive Cruise Control which I love has gotten loose and needs to be secured again as it is producing false positives with unnecessary brake warnings. The 0to60 times where on my SRT8 with the added weight of the hitch, and a 6'4" 225lb driver, and only 4 gal (i.e. 32lbs) of fuel.
I don't think it auto shifts, but I am not sure as I didn't keep it in gear to the red line. However, my understanding was that it would cut the fuel so that you didn't blow the engine, but would not auto shift out of the gear you were in.
I'm 6'2" 270lbs (not obese, just big bones) I used to be 220lbs when I was an athlete, so loosing 50lbs would benefit my health and shave 0.050 off the 1/4mile time!!
Oh yeah, this was in sport mode for those that don't know what they are seeing on the dials. I let the transmission do the shifting unless it's around a corner, can't do as well as it does in a straight line.
Impressive times! Its looking like the WK2 might actually be a little quicker than on average from 0-60 than the WK1’s. That was not to be expected IMO.
Wk2 looks/Is amazing...I'm up here in IA and would love to run one from a light..dealer has one but won't meet me at the nearest light...07 stock except for CAI..just wanna see...cheers!!!
Track mode, peddle to the metal in auto. I'm still working on when to shift with the paddles. Seems like their might be a break in period programed in the car, it seems like it is getting faster with the miles. Under 500 miles, the best was 5.9.
Has anyone done this with GPS? The factory computer doesn't really count IMO. That's like people posting low 4s and 3s with a dashhawk. I want to see some real world GPS numbers to get an accurate idea of how these measure up to the Wk1.
With a 25 gallon tank, a gallon weighs about 8 pounds so that is 200 pounds weighing down the Jeep or basically like driving with another person in the vehicle when the tank is full. When the fuel light comes on you have 3 gallons left or 24 pounds of fuel, that is when I usually get the better times.
Using track mode, got 4.8 with me shifting, and 4.9 in auto. 975 miles on it and 74º. Definitely gets faster with more miles. At first I was consistently getting 5.8's, then 5.3's around 500 miles, and now 4.8's. Cant wait for more miles......colder weather down here in south Florida........and a supercharger
