way too many factors/variables to consider,
Different weight (RC/QC/CC) different tire sizes, different axle ratio's, even DA plays a role, areodynamics
a headwind vs tailwind can shave or add MPH to any given run too.
Shift point RPM's will make huge difference to (stock is 5600, I shift at 6200-6400)
Spinning out of the hole can kill your 60' and ET's...BUT
can often have you close to 100MPH if you have a 3.55:1 geared truck that can hold off going into 3rd (by using 2nd prime) until you're right at the traps.
Blue Beast fastest (NA 4G ram)
is throwing down amazing numbers just by raising his shift points to 6800
( 3.55 geared RCSB Express)
But are higher trap speeds really the ultimate goal?
My target has always been a lower ET, and if I get a great hook with a higher stall and DR's, my ET's are quicker with a slightly lower trap speed.
My best ET's were 13.89 at 98.5 at 2500' DA
(converted to 0 DA = 13.41/102)
I've also had about a dozen runs at 13.9's and 14.0's
... with only 92mph in hotter weather when the DA is 3500-4000.
3.55 geared, 28" tall DR's (effective rear end ratio 4.30:1)
Murdered.. Lowered.. Alcohol Injected ..Blowered! 500WHP
