This guy ran a 12.2 seconds @ 116 mph in an RCF with only full exhaust
This is my video from last summer. I have more mods. Intake (only for noise), full exhaust and ECU race tune (pump gas Octane 94), but I am hampered by thin air up at altitude (4000 feet density altitude in the summer) just like in my 60 - 130 mph videos so getting 60 foot down is nearly impossible. My best run was a 4.2 seconds 0-60 mph and 12.58 seconds @ 116 mph at 4000 feet DA. That was a rather mediocre 2.09 second 60 foot.
To make it comparable to magazine numbers, Brooks' DragTimes.com sites correction for density altitude puts it at 11.9 seconds - 12.0 seconds @ 120 mph. I will be doing the crank pulley mod later on in the summer and re-do the run. Should be able to shave off 0.2 - 0.3 seconds in the 1/4 mile.
