I'm not defending what's-his-lying-face, but if you believe that Mafs you are much more blinded than I thought. As a drag racing fan from watching Pro Stock, you should know a big block V8 will put out well over 1,000hp naturally aspirated, and IIRC a 2JZ can handle something like what, 600-700hp with turbochargers on stock internals?
Obviously his car is fake, so it's not worth comparing to.
1000 HP N/A is doable but most pro stock cars run 2500~ im pretty sure (as in funny cars)
top fuel is 8000 hp out of a 500 CI block running nitro
