The question is, will this be worth it? There are a couple turbo options for the R8 which put out good power and likely much more than this blower will be capable of. VF-Engineering also already has an Eaton based supercharger for the R8 V8 using the larger Eaton TVS 1900. It seems APR's offering will be weaker than all other force induction options on the market.
Still, this is APR and if the product is priced well and undercuts the absurdly priced VF-Engineering supercharger ($25k) then this may have room on the market as offering good value.
