    isn't this 3.6 the whore of the V6 GM family? isn't there a blower kit out for this engine at all? You'd figure there would be as the LFX is used in EVERYTHING

    There are kits for the Camaro. KPE is looking at producing an ATS version of their Camaro supercharger kit. I have no idea when it will be ready or if it has the green light yet.

    that could be interesting. I wonder how much work it would be to retrofit?

    I think the supercharged Camaro produces over 400HP! what about the transmission and the rear end of ATS? They are strong enough?

    I read somewhere in these forums that the auto trans is rated for not much more torque than the NA V6 puts out. But i don't know if that was accurate AND these things are not exactly that simple. For example, I believe the torque ratings are almost always based on the highest gear. So if the overall gear ratio is such that a car can't pull max engine torque RPM in high gear then it could be safe to have more engine torque than the trans is rated at. If the Camaros use the same trans and gearing, it would be safe for us if it is for them.

    Another consideration is the rear end. Manual trans cars and Premium cars get a bigger, stronger diff than all other ATSs.

    That's what I remember too! But from engineering point of view, and also based on common sense, I really doubt they put a transmission on a mass produced car that is rated very close to engine's max torque. There should be always a large gap between these two numbers. However, GM is infamous for making such stupid decisions. Example: 2006 Impala SS. Or 2004, 2005 V1s! those Vs and regular CTSs share the same rear end and shafts!

    Ratings aren't immediate failure points. And you are right that manufactures will overbuild if its cheap to but sometimes cut things too close by normal people standards. The current generation Mustang V6s have a drive shaft that fails very often over 120 MPH. Why? because marketing wanted to be able to say over 300 HP and over 30 MPG. They got the last 10th of a MPG with a flimsy drive-shaft. That required them to add a 114 MPH governor. Of course they never told customers why there was a 114 MPH governor so the common conclusion was the base tires weren't rated over that. So people changed tires and bypassed the governor and ended up with a torn up undercarriage or worse. I never saw any forum posts about anyone dieing but most dead people don't post either.

    I would be concerned about the drive-shaft before anything else.

    The F/I Camaro's out there are running manual transmissions, they do run a stronger auto than the ATS (the 6L50E) but it's also a heavier car. Neither trans has had extensive aftermarket research to say if they're stout under pressure or not. I'm pretty sure there are only 1-2 companies doing stall converters for the 50E.

    That's what I remember too!

    This particular trans has seen use in the E90 316-330i, but more importantly in the X3 and X1 which are smallish SUV's with curb weights tipping 4,000lbs in the case of the X3. The 3.6 & 2.0T ATS are probably running the most power and torque of any 6L45E car, but they're also 35-3600 lbs. I would say it has a harder life in the X3, but certainly GM is making full use of it's capabilities in the ATS given the exact same power train gets a whole different trans for an additional 2-300lbs structure.

    There's no way it'll be in an ATS-V(I suspect the same 8 speed from the V sport, or a 6L80E), so the best answer here would be that; trying to figure out the breaking point for this trans is best left out of the picture. There will be no aftermarket upgrade opportunities.
