I was bored today so I decided to see if I could set a new record on my attitude now that I have a clutch which will hold. I ran a couple 6.8s and squeaked out one 6.5 sec run. I am wondering what everyone else with a hand shaker is running.

 

Haven't timed it, but its fast!!!! I'd imagine I was close to you, maybe a little more.

 

I am not sure on the 0-60 but I went 0-83.2mph in 8.3 seconds.

 

Try videotaping your speedo and tach while doing a 0-60mph run. You can play the video back on your computer and use the time counter on the bottom to see the exact 0-60mph time.

I have some videos on my old 0-60 tests on here somewhere, but that's with an auto not a 6spd.

 

I just use my attittude monitor it makes it easy. I know it launches hard in 4wd in 2nd gear and about 2200 rpms.

 

Easy...but not as accurate.

 

X2 on that. I took the time to tune the tire size calibration to my GPS to help with accuracy but even at the track, it would read up to 1/2 second faster in the 1/4 than what I was actually running. When I would use the numbers listed for tire sizes in the Edge book it would easily be 1 sec or more off.

 

For accuracy, you'd need real-time input of the tire's effective rolling diameter; you can set it exactly at a steady-state speed for a particular tire pressure and load, but accelerating through the quarter will change the tire's actual rolling diameter quite a bit due to centrifugal force... ever watch the tires on a dyno closely?

 

Yeah my juice is way off, I do the 1/4 mile test launch in 2nd 4x4. When I get done I look at the speedo and it is at 100mph. Then the juice tells me I ran a 16.8 at 94mph??? I don't think those monitors are accurate at all.

 

I stay away from those things. I was helping out at Overnite Trans. one time and a tire blew on the dyno. There is way to many if's when running equipment on the dyno to be lolly-gagging around and get taken out by a part with a lot of energy behind it.
