And daaaaayuuum judging by the second video you have that awesome v12 feature where flooring it actually adds gas!
I don't think we have a large enough bay for a v12, but if you did really put one in there, I'd be pretty livid at the gains. I want to say the 2uz-fe would spank you. Maybe you're being limited by the transmission.
Either way, if you plan to post here, share details. We like details.
Edit: The v12 is in his speakers. Had me going for a second, but honestly maybe one of the dumbest things I've ever seen.
