Why is the new CTR so slow?

There's no doubt that people will modify them beyond stock power. Once people start pushing power out of it, we will see how the torque steer gets.
I'm sure torque steer exists due to the nature of the drivetrain layout alone but the suspension geometry really does a good job of minimizing torque steer to the point where you don't notice any. My 9th gen SI with only like 250 tq torque steered really bad while the CTR with more torque has zero issues. How that will change with more power? Only time will tell.
So far at 390hp(+~100)/350tq(+~70), there doesn't seem to be any additional torque steer from the car.

That's cool, what mods you got done? How is it at launch? How is it when you get on it at the corner exit? All the fwd cars I've owned driven (ep3, 9th gen si, handful of others) wanted to understeer which made me get off the gas and steer it, while safer and probably saved me from an expensive day was very anti climatic, whereas the rwd and awd cars let me keep the power on. Given your name boosted 180sx I'm sure you're no stranger to rwd cars with power.
I've personally never driven the ep3 but god the 9th gen SI I traded in for the CTR had HORRIBLE torque steer. The torque steer/understeer is night and day compared to that car. You would be probably be surprised that the car will keep tucking in when you are in a turn. Probably the most least FWD feeling FWD I have driven.
I never really had a high power RWD car but I did have ~280whp S13, then a S14, and still have the S2000 currently, so I'm not a stranger to the RWD feel that you are talking about. It's one of the reasons why I still kept the S2000. As great as the CTR is, it doesn't give you the same "feel" as a RWD car but it's far from a understeering torque steer machine.

We can do some math here. Typically, when do you start getting torque steer in a car, specifically, a non Type R 10th gen Civic? Perhaps we can use the regular Civic hatchback with 177 lbft of torque as a reference? That car doesn't exhibit any torque steer from the reviews I've read thus far. If the Fk8 reduces torque steer by 50%, which is very conserative as this is assuming the FK8 has more torque steer than the Fk2, that means to get the same level of torque steer as the Fk7, you will need 354lbft of torque. Remember, the Fk7 with 177lbft of torque doesn't have any torque steer issue. That's now equivalent to the Fk8 making 354lbft in terms of torque steer. And if we go with 60% torque steer reduction instead of 50%, that figure jumps to 442lbft. By that time, I think we have to worry about getting the power to the ground rather than torque steer. And I don't know, I'm not a strong guy, but I think I can handle a little torque steering
We really need to understand why there's torque steer. Once we understand that, then we will understand why there's so little torque steer in the Fk8. Remember, the torque moment is a product of offset and tractive force. If the offset is small, then you will need a lot of force to cause any torque steer.
I think you're splitting hairs here, people love to talk about how cars act on the limit but very few ever actually get to see what the real limit of the car is and instead are hitting limits caused by their terrible driving habits or car setups that are way outside the bounds that could be considered proper. Generally, they are driving well inside of the envelope that will have most cars acting the same. Kinda like how people talk about the S2000 being a snap-oversteer machine. It's not, unless you have bad habits that lead to ending up in a situation that will allow you to quickly exceed available grip. Braking hard on corner entrance, lifting of the throttle abruptly in corners, not staying in the throttle when the back end gets loose, etc.
Suspension geometry strongly affects torque steer. I had a first gen Mini-S that had pretty bad torque steer, now I have a FiST that has even worse torque steer. I also owned a MK7 GTI that had very little torque steer, and have driven a CTR which had no obvious torque steer.

So... a 400hp fwd car vs a 400hp awd car will put power down the same coming out of a corner? And the snap oversteer in the s2000 is real, and what it means is that the car doesn't have approachable limits, it's grip grip grip let go, and when it does it's hard to catch.
Well I guess by your perspective fwd is a comparable setup to rwd and awd, and it's only a drivers bad habits that keep them from understanding this.

The idea here is that, every car is different. While in theory, RWD > AWD > FWD, there are variables that have to be factored in for each car. It's just that the FK8 from the factory is pretty well tuned and can put down its torque and power really well with its suspension, chassis, LSD, etc. It also helps that tire technology has improved a lot in recent years, which helps FWD cars with putting power down more effectively than ever before. Perhaps the limit back i the days was 300hp. But now, that limit has been pushed far higher.

Don't get me wrong, this isn't a debate of FWD vs RWD vs AWD. Just pointing out that certain FWD cars can do a pretty decent job with resisting understeering and putting power down effectively and setting decent lap times.

it's not my car, so it's just what I been told. Launch seemed fine, idk about corner exit though.

Haha I see where you are coming from. I don't know about the others, but for people who regular attend track days, many carry a set of dedicated track rims and tires, whether the car is a Miata, S2000, Civic, Porsche, Corvette, etc.
I don't think the OEM tires will get destroyed in one track weekend unless you are doing something seriously wrong. Agreed that the front tires are likely to wear faster than a RWD car. From my experience of tracking my s2000 and FK8, I didn't notice a huge difference in tire wear. I'm sure if you over drive either car, you will be destroying tires for sure, whether it's a FK8 or a S2000.

On a smaller course, with lower speed turns and where the vehicle is accelerating hard out of low speed turns. Or on anything other than warm, dry pavement. I don't know the answer, but how does the braking compare?
