I am curious about CVTs and their performance potential, all threads pertaining to CVT performance seem to look at them as a hinderance. Im curious what it would take to run one. Anyone out there actually know the Honda unit? Supposed I attached one to a K20 with kpro, completely independent from the trans, can one control it? I has a 1983 Honda Odyssey FL250 and its CVT was very simple, dad sold it the I was 13 so I never had the chance to figure it out. I have watched numerous videos on generic CVT but nothing comes up Honda specific. When my Element was recalled for an air bag, I drove a Nissan Altima for a month and while I wouldn't buy the car, the CVT 4cyl combo was rather impressive.

 

I'm going to wait until the new Honda's that have these stupid trannies tend to have around 80k or more before I even think about getting one, after the fiasco that Nissan put their owners through when they started running cvt's and they were failing after 50k.

 

Is this for a car or for an ATV? The 96 civic HX had a CVT, 115hp and it was fine. Yeah Nissan's junk is built totally different. If you look at an exploded view of a Honda CVT for the D16s, you'll probably see the way they are done. If you wanna go crazy with programming you can build in shift-points for it to simulate a regular slushbox automatic. What's your end goal? I understand your seeing the benefits of a CVT, but theres a cost associated with it, and for higher HP applications, as you can see lots of car companies are still making automatics. The new Civic EX comes standard with a CVT but the new Acuras come with upto a 9-speed automatic transmission. Theres a reason they did that, cause as you can imagine, at that many gears its going to be lighter to run a CVT.

Compare cars side to side, an Accord with a regular a/t could outdo fuel economy at the time of an altima with a CVT, but theres also the factor of rotational mass, car weight, etc. My point is CVTs may inherently bump effeciency, there's many other factors as to why slushboxes with torque converters are still being designed.

 

Its for a car, I mentioned the ATV cause its what I had experience with, seemed so simple. I also drove a CVT insight and while not the most powerful, riding peak torque felt right. I guess a 9 speed would also be desirable but again, how would you separate the engine and trans as far as ECU goes Ideally I would want to use a L15 or K20. Im not locked on the idea but I have read about CVTs in F1 and while banned completely, they were considered the ultimate by some.

 

With the size limitations of the CVT, there is no performance to get out of it. On paper a CVT can be faster than a manual or even a DCT, but in real life that can't be done with a stock Honda based CVT.

 

I spent my first years racing with this "tranny" and I guess 250cc seemed really big for an 8 year old but can imagine what 2400cc version would look like, I don't have anymore questions but enjoy my first Honda pic! thanks for the replies
