Thats what i thought. But i wanted to see if people have exact dyno number for stock 13-14 shelby gt500s and 13-14 RS3.
I know a guy on instagram has a 1080hp shelby and says it makes 918whp. Could that be true?
When u take 25% of the 1080hp its not 918whp its 810.
So is there any way that ppl can find the rwhp of theyr factory car by calculation?

Thanks buddy
