Are those times with the factory 20" wheels? If so, sometimes even with the 3.92's I assume you have, it might help to have a "little" bit of spin to help wind it up quicker in the powerband and get those big hoops rolling.
Good Job!
Any idea what kind of air or altitude (DA) that you were working with that day?
I've run pretty much every drag strip in SoCal (before they all started shutting down) with pretty much every car or bike I ever owned or were invited to drive for them. I miss it. It could be frustrating, as it really is much more of a science, with 100 or more tiny things that impact every run... but most people think it is a quick, simple "step on the gas and go when you see green" type of thing.
Glad to see people out there still hacking at times. A new PB is always a great feeling. And, damn well earned, I don't care what numbers one is running.
*I have some drag vids in my sig line if you are bored and have some time to kill on the Y'Tube.
