This is on a Holden. So, rwd and through a t56. 501whp.
I'm not sure you can really compare it to zzp's most likely inflated dyno numbers. But, it's still an awesome video to listen to.
It's a heavily built engine. Max power was on a 58mm pulley, which is about 2.2". He said they lost a little power going to a 55mm pulley. (~2.16") This is with an OD balancer, though I'm not sure how overdriven it is. Blower rpm should be well into the 20k rpms though. This gives me a lot of confidence in my 2.3" and 5% OD setup performing well.
