It's not about trying to be right or wrong, just the facts. But you did bring up about 5 other points that could potentially add to the losses on a chassis dyno vs. engine dyno that help explain the range of 15% to 25%.

So far, the least losses I have read about are the less-than-15% losses for the newer Corvettes......but I think the opinion was that the factory understated the FWHP to begin with since the RWHP numbers were so good.
