Convert 1/8 times into 1/4 times?

While I'm sure someone will come up with an equation for this. It is only an estimate at best, and very well could be far off an actual 1/4 mile run time.
 
I think for a typical 11-12 second TR you multiply the 1/8 et by 1.57.
Of course until ypouv'e run the number in the 1/4 it's just an estimate as I have found the second 1/8th is much harder on the car and tune is more critical.

Very true the 2nd 1/8 is way different. My dumb ass local track made itself 1/8 for the weekend due to a bunch of racers from MAINE who got snowed out at their 1/8 dragstrip.

Anyway Me & Pronto ran 8.0 & 8.7 in the 1/8. I am guessing one is in the 12's & the other in in the 13's.. Well I won't know till spring when they open up again.
 
Bad tune, bad 60', What did you expect? :biggrin:
 
lets slap um on the dyno and tune them out some more. put the wide band on them and see.

Your 8.0 is a 12.48 and the 8.7 is a 13.57.

I attached a conversion chart, but not sure how readable it is??

Actually I ran a 7.9@87.32
Steve's going to have Russ look at the car when he gets back from Reynolds. Got some knock happening and we can't seem to find the cause.
