13.06 @ 104.71 and my actual time was 12.99 @ 105.02 so not too far off for me.

Generally (and I mean generally), 1.57 times your 1/8th mile ET. FWD/turbo cars tend to be a little better than that because they have a bigger charge on the big end. My car on the other hand is a little worse (1.585) but I'm planning to do better at the next track day :evil2:

Yeah, I haven't had any time to mess with anything, but I'm feeling good about this next track day :wink:

BBB, You probably have alot of weight in that TRUE BEAST of a car. If they make carbon fiber, and plexiglass for it, that should probably help alot.

That calculator is WAY off, even for a nitrous car. I tried it, since on the Probe's quickest 1/8 pass, Donald had to lift about 1000 foot out...it went 4.41 @ 163 to the 1/8 and 6.84 @ 190 to the 1/4. The calculator had it going 7.0 something. Slower than an aborted pass. @@
