Why would it be lazy & have stupid amount's of lag?
That car spool's up almost instantly. It's also not all about how much hp it makes, rather how much torque it makes, how soon it makes it & across a very wide power band. 710lb/ft (994Nm) @ 5000rpm on 13.5psi.
It may seem like a waste to fit 8 turbo's to a gen3 chev & you can make more power with just a big single turbo!
But I give him credit for trying something totally different. Christ, there's 280+feet of piping under the bonnet!
