Im curious to my 1/8 mph because i wanna see if my car is running normal at that point. The track i goto leaves the mph for the 1/8 blank but calculates everything else. Anyway to extrapulate the 1/8 mph from the time slip?

Divide by 1.26. Not exact but should give you at least an idea.

Pretty close. What'd you run in the 1/4, 108 n'change? If so then 85 or 86 is right in the ballpark. I can give you an example of how my car ran when the former owner had it. With 308 to the tires through a PY3400 stall and 12 bolt it went 8.21 @ 86.9 in the 1/8th and on the same pass it went 12.67 @ 109.9 with a 1.86 60' time.

check my other thread, about my trip to the track. my time is in my sig. Something seems amiss with the car, my ET should be lower with the 60ft im running and trap.

These "calculations" don't mean much at all in my experience. Some cars are fast off the line and others aren't. My 1/8 mile speeds and ET's more often than not suck when compared to others, but my car more than makes up for it in the last 1/8 mile because it's a real top-end performer. Your best bet is to talk to the track officials and ask them why their timeslips are f**ked up. The fact of the matter is, the 1/8 stats shouldn't be blank.

they time the 1/8 mark, just not the mph, they dont have the equipment im told to track the mph at the 1/8th.
