every type r I've seen run on the dyno makes an initial "barking" sound before a woosh of air but your right, doesn't chatter/sputte like that supra does in that first corner...?...maybe it's my laptops shitty speakers screwing up how that supra sounds but that does sound like a type r.
Yes, big turbo supra's are notorious for compressor surge too, imho because many run too heavy of a bov spring and too large of a compressor for the small motors breathing at lower rpms.
