I agree its unlikely to be 13.5:1.

But going down hp/l would be just more due to the less efficient air/fuel mix as you start asking your intake/exaust and fuelling system to fill larger and larger cylinders.

I would imagine anyway - someone can surely correct me.

If you scale everything else up appropriately it should actually be more efficient. Less surface area per unit of mass through the pipe.

I am betting that hp/liter is reduced because cams are somewhat less aggressive (less duration and overlap) to minimize (essentially eliminate) the torque dip. Personally I would have been fine with keeping just over 100 hp/liter and keeping the torque dip, but it seems like they've done a good job of keeping it revvy enough while making midrange nice and fat...

This was exactly my thought as well when first seeing the power curve and power rating. I would be they could have gone higher, but tuned conservatively to minimize the dip so people can stop complaining. Yet I would have much rather had the bump in power and a larger looking dip in return.

Late to it, but this is probably the single best thing I've read to date. It's in no small part thanks to your real-world experience with the platform, so definitely glad you got to do this.

At this stage, my complaints are all aesthetic in nature. I really don't care for the big duckbill, but since I also don't care about the other upgrades that come with the Premium price-point - I think the wheels are ugly, and I don't care for Alcantra - I don't need to worry about it (honestly, I'd be curious to see how the deck lid looks completely smooth). I don't think the interior dash sculpting looks quite as nice as the outgoing model either but it's growing on me. Still bummed about losing the armrest grab handle though.

As my FR-S turns 9 in a couple months, I think I'll be right on track to bump up to this next year. It would be pretty handy if suspension (or at least springs) and cat-back exhaust could just swap over as well.

Pretty close to this probably.

I'm thinking that the gear ratios may have been tweaked on the manual for fuel economy hence the 6.1 0-60

I'm not discounting either of those thoughts (as I am just spitballing), however I will note that this article translated from Japanese, Takeki Kajikawa the head of the power unit talks about how the issue he faced when designing the FA24 for natural aspiration was the lack of Air at high revs as the cylinders are made larger but the rev limits are kept.

He suggests that in fact what helps them is the pre-mixed air from the port injection at high revs, because they are able to ignite without waiting as long for the air to mix.

Interesting to note that this quite different from the current car - which uses only direct injection at high revs.

Very interesting. Perhaps also a hint for tuners of _both_ cars at high revs to take on board.

Also agree with it looking like a gen 1 with a bad body kit, but glad to hear it looks better in person.

I still love my 2013 (e85, track mods, weight reduction) even after owning it 9 years, but looking forward to the gen 2’s. I’ll probably upgrade down the road.

Did you have to get the recall repair done to your 2013? If so, how'd it go, and did you do anything special to get a good result?

I'm gonna wait a year. I'm thinking auto this time on flex fuel

Yeah had to get the recall done. I specifically chose a large local dealer that had done a bunch of the recalls. I spoke to the service advisor and he said they had two master techs who handled all the recall work. Neither had had any come back for engine failures or major issues. I had the spark plugs changed while the engine was out. Tried to make it easy for them by disconnecting any mods that would be in their way (oil cooler). Afterwards did an oil change at 1k miles. If you’re really concerned, you could drop the oil pan at that point to see if any sealant bits are clogging the pickup.

My engine currently feels like it’s running strong. It’s done around 15k hard miles (track and canyon) since the recall and hasn’t missed a beat, so I feel pretty good about it. That said, I recently did a UOA that showed somewhat elevated aluminum levels in the oil (9 ppm vs 3 ppm average) so I might not be in the clear just yet. I’m not too concerned given how hard I’ve been driving this car, but it is something I’m keeping an eye on.

I think the best option is still to avoid the recall if you can. If you have to get it done, go to a large experienced dealer who has a clean track record.

Here's what I thought:

I also welcome any questions/etc - I couldn't put EVERYTHING I learned in the article.

Hey CatDaddy,

Will you be one of the drivers of the local test?

If so can you please try trail braking in both with the assists off?

Thank you!

[timurrrr]

Also, is there a way to have assists off but keep the regular circular tachometer?

Pretty sure you can customise it however you want.
