Got a dyno graph Bean? Is the VF23 the equivalent to the td04? imo numbers is pub talk, it may only make 130bhp up till 4500rpm. It's all about making the power useable for what you intend to use the car for. All you have to do is look at Spuddy's car, it makes 570bhp, but at 4000rpm it makes 63bhp! Thats 70bhp less than stock!
