    No downsizing. They are playing to the market. 90% of Tacoma's never see Off road. They sell more Tacoma's because of the locker button or the TRD Sport Scoop than because of the locker itself or the TRD S/C.

    Toyota will still support the Offroad community. That's a big reason why they didn't add a few inches to get to the size of the Colorado and went with a lighter truck again. The motor doesn't usually make a great off road vehicle (see Rubicon with the Pentastar). As long as the engine is reliable, there is a real locker, and the suspension is easy to modify, the Toyota Tacoma will still excel offroad.

    Highly doubt that. Then again I never stated any statistic. "Good portion" could really mean anything, and here we are you see disappointment lurking in this thread.

    Otto versus Atkinson cycle will likely be controlled using VVT which relies on oil pressure and valves. There isn't a real technical limitation there for the S/C in my mind.

    ~1.5 million 2nd generation Tacoma's have been sold. 1% of that is 15,000. I'd say that's 1500 S/C per year being sold at excellent margin. That number is probably close. Seems like a good financial strategy to me. Toyota is probably looking at other factors when deciding not to continue to make a TRD Charger.

    Well let's not forget the tundra, 4Runner, Camry (?) and other models that support the s/c. I agree that financially they probably aren't selling as many as they'd like. But let's take other factors into consideration like engine standards or whatever, mpgs, and the such; these obviously put a role into discontinuing the s/c as well.

    It's a shame.

    Tundra S/C doesn't share components with the Tacoma S/C. I know someone with a S/C Tundra, his S/C is easily twice the size of mine.

    Can you even S/C the new 4Runner? Ever since they got the newer Dual VVT version of the 1GF-RE I thought it was a no no.

    Who cares about MPG on an aftermarket part? The TRD S/C filled the hole for Toyota of not having a V8 for those guys who want 300 HP and +300 ft lbs of troque.

    Anyways, they stopped installing the Tundra S/C through Toyota in Canada a few years back supposedly because of a couple of blown motors. I think the reliability of having S/C on more complex motors eventually lead to the decision Toyota made.

    I know how the Atkinson cycle will be implemented, I was just thinking that the bypass valve on the the SC will need to be linked to the intake cycle on the engine somehow in order to prevent air from being forced into the cylinder when the piston is trying to push it out due to delayed closing of the intake valves. Seems like the SC would have to have its own mini computer that is linked to the main ECM.

    Atkinson cycle with a supercharger will result in miller cycle engine. True or false?
    The thing with different types of engine cycles and fuel economy get very complex.
    This is beyond my thinking, I'm out..​

    OR have a bypass valve that opens like the current TRD S/C when the engine is in cruise/atkinson cycle.

    The locker is not what I thought it would be. I was hoping I could use it at any speed and while in 2wd. Instead it got to be in 4 low and under 3mph. But then again I may fully not understand on how to use it.

    Ten minute mod to get the locker to work under any condition:

    http://www.tacomaworld.com/forum/technical-chat/4838-cheap-free-mods-28.html#post684156

    This is why the Tacoma rules. Snip, clip, splice, or insert a relay and you can still get the truck to do things that it isn't supposed to from factory.

    You don't want to use the locker at high speeds though. That's going to blow out your rear differential real quick.

    Isnt the bypass valve contolled by vacuum or manifold pressure or something? In other words isnt it normally mechanically activated? If so, what would activate the bypass when Atkinson cycle is engaged? There wouldnt be any butterfly valve slamming shut to suddenly change manofold pressure or anything. It would need a solenoid and possibly a mini ECM to control it, that is somehow tied to the engine control unit. Seems complicated and might push costs over what people want to pay.

    Maybe use a circuit from the VVT oil actuators to control a simple solenoid controlled bypass valve?

    I get what you are hinting at but there are ways around the issue without adding a computer. Would adding another ECU lead to possibly perfect operation of the Atkinson cycle with a S/C? Sure. Bypassing the whole problem though would be pretty simple.

    Toyota didn't just scrap the TRD S/C for the Tacoma, they scraped it for everything.

    Aaaa, gotcha. I didnt know they dropped it for everything, thought was just for the new Tacoma engine. Thanks.

    Glad I grabbed mine when I did! Looks like Toyota of Dallas already raised their prices. Have a feeling prices are going to skyrocket soon

    For new ones the price is going to go crazy. If I was Gadget at URD I'd be putting in as many man hours as possible to try and get the URD UCON connectors done for the +2009 Tacoma because he's going to have a lot more demand very soon.

    Yeah I know all that, but you're missing my point.

    I said Toyota models in general
    And this guy skewed it and said Tacoma owners. Clearly they wouldn't stop selling Trd superchargers just because of Tacomas.

    I wonder what impact some political policies have effect. Didn't CARB stop certifying the chargers after 2012? With more states andd the federal government adopting CARB standards, it would be tough to justify keeping a program that was very limited in the first place and second, can become a legal liability if states don't grandfather emissions rules.

    As far as I know the SC was carb legal all the way up to 2015? Hence the "changes" to the reflash every year? Or am I wrong?
