Not a G8 , but a car we built with 1000 rwhp dyno graph . Just figured I'd share it with you guys , it is a 427 twin rear mount turbo set up in a 2003 zo6 vette which is why it looks so peaky , it needs an auto trans to really be fast . This was done on a MAF tune , and I will be switch to speed density to get a better fuel map out of it , should make another 50 or so rwhp , not that he needs it , it is a street car , just passed inspection . Got traction ? Nope , not even with the 11.5 slicks at any mph right now which is my next job along with the speed density tune . It made 1002 rwhp through the slicks and it was 94 degrees .
