I am J790 on the left.
At 7,200 rpm,  I sidestepped the clutch, slid my right foot off the brake
and crushed the roller pedal as hard as I could
(Yes, I don't use the e-brake as it broke some years ago.
I just put have my foot half on the brake and half on the gas).
I hit each gear just as hard shifting at 7,400 rpm.
All with a stock 4.12 gear box and not using 4th I  ran a best
of
13.79 at 93.00 mph without blowing something.
