you might be able to do 350whp on a VF with race fuel or E85. i have hit around 340whp on VF48 with meth & 91oct. if you want true well into 350WHP you need a bigger turbo than vf48. depending on how your hybrid was built it could be more knock limited than some other engines. and at 5000ft you will have a harder time making expected power with any turbo.
