I thought the engine's were now around the 750bhp mark? They reduced it significantly when they went from V10's to V8's?
i stand corrected
700-780 brake from a 2.4 V8
as opposed to around the 960 brake from the restricted 3.0 v10 at 19,000 rpm
but button was still in a slow car compared to the rest of the field when that race was run plus he had no launch control so he could have done at least a 8.5 1/4 if he'd had decent machenery
