If I wanna upgrade the intake manifold, I want this... but of course, it's impossible to get one Orz

What exactly is this that I'm looking at??

I can run a base line at PTUNING but let me finish break In I'm only 300 miles in lol.

So far it's been lifted, checked for its new tech by local shops and driven hard by an editor.

My car is turning into the community car lol

Hey Zaku, in the Redline review, he mentions a different clutch and transmission feel compared to the old one. Is this your finding as well?

Also, was there anything the shops found that was not noted in the MY2017 changes document?

Contrary to popular belief dynos are incredibly inaccurate and the variation on even the same car can be in the 10s of hp/torque even if done on the same day. The only way a dyno would have even a little value is if it was a side by side with an older car. Even then it would have to be a brand new (or equal mileage car) and done within an hour or so of the 17. Anything else may just as well be a random number.

I wouldn't expect anything other than at least a comparison of a stock 13-16 run from the same shop. Most shops that would be interested in checking out the '17's more than likely already have plenty of stock runs to compare to.

I agree that numbers can vary, but a lot of that talk is exaggerated. Same dynos usually put out similar numbers within margin of error, as long as elevation isn't drastically changed. We can still get a good idea of changes, such as powerband and if the marketing dynos showing higher low end torque are reflected in real world results. A beefier powerband would be very evident on any dyno regardless of number output.

Yep. You are looking at it realistically and understand what those numbers represent though. Many here will just look at the straight numbers and figure way higher, the same or (heaven forbid) lower. The numbers game is a huge trap for those that do not know or care how they are actually applied to or used by the car.
People put far to much trust in dyno numbers when one car could be taken to 5 different places and have 5 radically different readings. When trying to see changes and tuning one car, on one machine, they are a great tool but when trying to be used as a general overall statement they fall way short.

I feel the same way, and agree with the review. That's how I feel also, I'm guessing it's the gearing and the way things are set up its definitely a lot smoother on the new car.

Nope not yet so far it's only been a visual inspection. I'll have more info once I reach 1000 miles where I can maybe do another video and have a look at everything performance related.

It's probably because the revised chassis components got stiffer and it's putting the power down a lot better than the old car.

Yeah, but I already have Bridgestone Pole Positions and Blizzaks for the winter on the factory wheels. (although they will probably never see the snow)

It seems like quite a bit of work to do.

The part numbers are:
14001AC540 for the Intake Manifold
14035AA720 for the gaskets, you need 2
And I couldn't find a part number for a throttle body gasket, unless you can use the same one as the MY16.

It just seems like a lot of work to go through for virtually no gain. I think I may pass. If anyone else finds out anything more, let me know.

Definitely! I wonder if the change is due to similar reasons Mitsubishi changed theirs on the Evo X from metal to plastic. They realized plastic was ok at stock heat levels. However, swapping to metal was always one of the first recommendations from tuners as the heat was too much for the plastic when pushed beyond stock hp. We all know these cars run hot stock, so maybe this is more of a preventative measure.

There's something up with the 2017 Auto...They're giving "more power" and a different rear end to the manual. My guess is they're just trying to appeal to a different market with the AT.

Manual gets a RED one AT gets a black one...

Maybe they had a lot of leftover diffs and engines from production lines, and instead of scrapping them, they decided to give the new stuff with slightly better performance to the higher performing manuals and their more performance oriented (generalized statement, but mostly true) owners.

I'll bet that next Model Year, the autos will get most (if not all) of the changes after the existing supply is gone. Plus, if it IS a noise issue, they'll have fixed it for the auto in a year.

Subaru/Toyota isn't a Mom & Pop operation that has extra engines kicking around that they need to use up. The materials flow is carefully planned and scheduled so they have just what they need when they need it so there is no warehouse of spare engines sitting forgotten someplace.
I am not privy to production numbers but bet there are 5 or 6 ATs built for every MT. The MT elitists can believe what they want but the AT is starting to rule the car market and even these cars are not immune to it. The difference is more probably related to emissions concerns with the ATs and is not some conspiracy to reward MT drivers.
