First Time Drag racing

The Wallace calculator seems like a fun toy, but I'm not quite sure what it has to do with reality...
I figure he has about 80-100 more hp than me. Plus his gears. So if I put 3.91 gears in my car and hit it with a 100 shot, it should go low 12's at least. maybe quicker and into 11's. (figuring I'm 13.4's now)
