BFG's are fuckin garbage. MT's, M&H's, Nittos and Hoosier are the tires to run. While drag radials might not be much lighter, 1 pound of rotating mass is a ton.
To launch a car you only need to rev it as high it needs to not bog on the hit. So yes, that's either just under VTEC or just over the engagement. And a good DR at the proper inflation shouldn't have a problem with that.
