I have a PRM intake as well, but I am in fact, looking forward to the T1R just to see what it can do.
It's not that I'm not satisfied with my PRM, I am, it's just that I know as a product designer that there is no perfect solution.
Ultimately, I feel the PRM is at its best at freeing the motor at the upper RPM ranges. Not to say that it losses something down low, but it's screaming top end makes the bottom seem flat by comparison, even though, and I can't stress this enough, it isn't.
What appeals to me though, is the fact that the T1R could provide even more of that down low power the car needs, while possibly keeping some of what's up top. Not to mention as a designer I'm just flat out curious.
So it's has a series of bends, that's fine. Ultimately that longer track, if given the right volume, flow, and harmonics, can increase airflow through the system at lower RPMs, promoting the filling of the combustion chamber more effectively.
Here's a simple method to illustrate this, get a drinking straw and try and breathe through it. You'll find that long drawn out breaths will be the best way to move air through it or rather, that the straw is most effective under those circumstances. I.e. low RPMs.
The PRM for instance, is like a Boba straw. It's shorter and larger in diamter. Find one of those straws, and breathe through it. You'll find that the best method is short rapid breaths, i.e. high RPM. The ingenuity in the RPM system is that the tapered filter creates a situation in which the velocity of the air passing through it must increase in order to keep a steady rate of flow, so it can provide much of that velocity increase and increased flow at lower RPMs, even in a shorter assembly, while still being short enough to not choke the motor at higher engine speed.
Having said that though that box on the T1R, if of sufficient size (there's some ratio between displacement and airbox size), can provide enough of an air reservoir that the motor can draw from it at high RPMs without being constricted by the whole assembly, and hopefully not empty it before it can refill itself between firing pulses. If they manage that, it's possible that the T1R can provide some of the PRM's vicious top end, since the effective length of the intake then become the distance from the TB to the box.
Anyway, sorry for the long response, hopefully someone out there found it enlightening, but I just hate to see someones product get derided as a product designer. There is no perfect solution, no right one for all. That's why were all here looking for this kind if stuff anyway, in the hopes of bringing our cars closer to our ideal.
So maybe the T1R will amount to nothing more than eye candy, or maybe they'll be able to better what Honda was trying to do with the stock airbox. Ultimately I hope it comes to market just so we can see, though I must say, it will have to be pretty good to beat what PRM has come up with.
Perhaps we should just split the difference, and put a PRM filter on a T1R airbox, lol, and make everyone happy. Or better yet, realize the fact that design is an imperfect science, and appreciate the fact that we (will hopefully) have choices.
Hell I just love the design process and everthing that entails.
P.S. Before someone points out the obvious, I understand that in a motor flow is only in one direction, unlike the breathing exercise, but it does non-the-less illustrate the fact that everything is compromise, and that there is a balance that must be achieved between the intake and exhaust sides of a motor. Remember, motor=air pump

Very well written, but as for boba, those little jellies always creep me out when they pop through the straw, like someone left boogers in my drink. But thank you pilosopo for explaining what I tend to see as numbers, with an eloquence that would make Patrick Stewart proud.

Thanks man, I knew what you meant the while time, lol

Very nice analogy.
Thank you, much appreciated coming from another designer.
I'm just glad someone read what I wrote, that was a long post! lol
OK..... Last warning for both sides of the fence... keep this thread clean and play nice or I'll fix it and "YOU" will not like the result..... read through the fine lines... if you want....
Have a nice day..and please keep this thread back on topic.

It will probably be about $450 CAD. That is just a ballpark price.
