Drag Racing Tech - How much gas do you run the 1/4 mile with??

The last time I went to the track, I ran with under 1/4 tank of gas...because of weight. Someone told me that my car might actually run better with a full tank because of the weight on the back tires and the weight transfer. Is this true? Should I keep it under 1/4 tank? Please let me know, I'm headed back to the track tomorrow and am not sure if I should fill up.

I usually run with about a 1/4 of a tank or so. I run with ET Streets so traction is pretty consistent for me. However when I used to run with Nitto DR's the more fuel I had the better my tires would stick.

I run with an 1/8th of a tank usually. Traction isn't a problem with my Hoosier Quick Time Pro's even though they're only 8" wide. My car slows down noticeably if I have a half a tank or more.

1/8 tank here

still haven't run that car yet :bang: , go with a 1/4 tank so you dont have to fill up after 6 or so passes :jest:

ya usually 1/8 here too

start 1/4, end at 1/8 tank

1/4 tank.

idk i find when i got a full tank its better because i get like no traction if its around 1/4
