911 rwhp #'s
 

Sorry if this is the wrong section...it's been about a month that I bought my 04' 911 and my big brother and his friends are already hating and talking non-sense. I wanna know what kind of #'s I'm putting down with my mods. My brother claims that his full intake,exhaust and tune ws6 will beat me. My car came with gt3 intake,injectors,gt3 exhaust,and a tune. I don't talk without knowing what my chances are in winning the race. I'm pretty sure I'll beat him I just wanna by how much.
Thanks guys!
