    ith 93 octane fuel and some tweaking in the hands of a good tuner, this motor has great potential in the ATS-V it would seem.

    re: Edmunds dynos LF3 XTS and CTS Vsport

    Thanks to them doing a back-to-back with a CTS-V, we can do some armchair maths. At that armchair, the LSA put down just about 500hp and 500tq - a 10% drop from stock factory ratings. So the CTSVSport is making 480hp and 430tq.

    Now obviously this could be a cherry picked example from GM. Could be a tweaked press car.

    But if NOT, it's putting down a good deal of power - the fact that it came so close in band and curve to the LSA is impressive.

    Yeah when this thing goes in the ATS-V it's going to fly.

    I'm going to try to not be jealous of early adopters of the ATS-V. Most likely I won't be trading in my ATS on one for a while, if ever.

    Armchair maths yield ~430HP and ~480TQ ... You got the maths backward

    "By logging data from the OBD-II port we saw something intriguing: The CTS Vsport's throttle was not fully open in the midrange. This is a strategy to mitigate boost overshoot as well as manage the LF3's torque output."- From the article.

    The tunners are going to go crazy with this engine! Can't wait to see what they can do with it!!

    ----------

    More interesting than the article is the comment. read church123 comment! the car is only running 12psi.
