Hondata R&D finds limit of Civic CVT

[HondaPro]

The only stupid questions in life are the ones you don't ask. I'm here for one reason. I watched the video and replayed it thinking I missed something. It's like Mr. Hondata is building us a watch but not telling us what time it is. He fudged up his transmission but isn't exactly saying the exact point it failed. As if he just noticed when he started losing power. It's starting to sound like if you want real gain with reliability it's in the manual. Or just wait and buy the Si.

Funny you ask questions like this when you "Pro" in your name

i just want more gains but keep the reliability lmao

Honda's never built a strong 4 cylinder transmission. We've got N/A K series guys breaking 2nd gear with 150-160 ft lbs of torque.

So would it be safe to say you could achieve higher torque levels safely with a manual? And how much more?

I've made nearly 300wtq with just a tune on our 6MT with the only issue being the clutch wanting to slip.

 

[ayeerock]

so what your saying is... mine as well get that tune and enjoy my car to its higher potential?

LOL I don't think there's any reason to just toss the CVT if you're enjoying the car. I think as time goes on and PRL comes out with their cooler we'll see some sweet CVT builds. I've tuned several CVT now on both Hondata and KTuner -- Hondata's limits are super conservative. That's their decision to set them and as I've told several of my customers -- if they are happy with the results and how the car drives, enjoy it. If they want more, there's more there

I love my CVT! Got tired of shifting thru LA traffic every day. I'd love to tune it to get that extra oomph and nothing more! You'll be hearing from me in the future friend I do miss downshifting on young kats tho

MT gearbox reliability is mostly dependent on how you drive the car. Shock loading is hard on a gearbox. I have 9 years of landspeed racing with K series engines running transmissions with only off the shelf Honda parts handling 500-600 lb-ft torque. The fastest we have run is 245 mph on a K15 turbo CRX. We have set close to 50 landspeed records with no transmission failures.

I've had good luck on some of my cars too. That doesn't change the fact Honda's transmissions are not very strong. Andrew's K20 mr2 broke 4th gear, broke 5th gear, broke even 6th gear just doing high speed pulls no different than what your landspeed car does. Your landspeed cars also do no run on a street surface. Do the gears last a while? Sometimes, sure.

I share Hondata's outlook as well. In the hundreds of thousands of miles we've seen across owners from various mod paths, clutch engagement and transmission movement (between shifts) are the biggest contributors to failure.

we all share Hondatas outlook, it's a given, the point is they are not reliably strong.

So clutch engagement and trans movement is why I can shred all the teeth off 4th gear just by rolling into boost on a K series? Without making a shift. Just leave it in 4th, and ease into it? Must be the clutch engagement... couldn't possibly be a weak gear that can't take the torque?

LoL
