I was reading the technical specs on the three available transmissions. The 5spd auto for the 2.0l turbo has an "allowed torque" of about 253 lbft. The 6spd MT for the 2.0l has an "allowed torque" of 225 lbft and 3.8l has an "allowed torque" of 289 lbft. The "maximum torque" of the 6spd auto is 441 lbsft.

I don't know what the difference is between "allowed torque" and "maximum torque" but I hope one is a median torque amount and the other is a true maximum limit. Otherwise it may be hard to get some serious power from these engines without breaking tranny parts (unless you have the 6spd auto tranny).

Does anyone know whether this will be of a concern to tuners?

It's hard to say until people start raising the power levels of the cars and breaking stuff. Obviously power handling specs on transmissions can vary greatly depending on the parts used to build them. For example, if a clutch and pressure plate is used that is not designed to handle more than a 2-300 lbs of torque. It may be that all that is needed is a performance type clutch kit (pressure plate, clutch disc) to raise the "allowed torque" value. Hopefully that is the case.

We'll just have to wait.

Oh I didn't even think of that, doh! OK, that makes sense then.

Any idea on who builds them? There is "rated" and "max" numbers, never heard "allowed" before.

What I have been told by Ford, Dodge and GM instructors, there is always "room" built into there numbers. More or less take the "max" number that they state and bump it 40%, thats the real number.

Only time will tell what we have in store for us the what parts need to be made.

I tried looking around on the web but not much was coming up. According to the technical docs on this forum the model number of the manual 6 speeds will be M6VR1 (T4) and M6VR2 (V6). I'm hoping that you are right that the tranny's have some room to play with cause I do not want to be replacing transmissions!

I agree with FastCoupe, I'm not interested in replacing the tranny, considering I can do most of all my modifications for the price of a racing transmission assembly.

FYI, cobalt trannies that are rated to less than 200lb/ft are being used in 600+whp cars that run 10's and faster with no problems at all. Upgraded clutch and a good driver do wonders. It's usually the people that can't drive worth a lick that toast trannies.

Ya that's a good point Ralli.... I've seen the same with some of the Honda cars... One of the Speed shops around us has a low 10 second Honda, pushing around 900hp i believe, and basically the stock tranny... Maybe we'll get fortunate with the Genesis Coupe.

It's more like 426 HP (not 900HP). Well it might be more than that now, but last I saw it dyno it was at 426. Not sure the tranny is truly stock either because I'm sure it's got LSD or something to put the power to the ground. SRT-4 is a good example too, many of them running around with 400+HP from the stock 230HP. Every car is different though.

Well, I was going with the turbo4 & 6sp, but now my brother is going that route because he needs a car now & his funds are not as good as mine. Therfore the tranny is not a big concern for me anymore being that I'm going to give that badass ZF 6sp auto a try & its good for some serious torque. I know, I know an auto, but my bimmer's is pretty tight. Hopefully by the time I purchase, there will be a lightweight track version, with direct injection & paddle shifts. I willng to wait to get what I want. :evilgrin:

Well that only means one thing......push it until it lets go!

I'll see what I can do. :rofl:

 

[civictd04]

Yeah I agree, let it start slipping and then replace the clutch, etc. Were you going to check on who will supply an aftermarket performance clutch kit for the car? Let me us know what you find, cuz I'm sure a lot of people would be interested in upgrading this part if it starts slipping with upgrades.

Old topic, but important one

I want to reitterate that I hope that this transmission is not a weak link. The clutch is not a problem since I've already decided to install an after market racing clutch. Although, I would like the factory one to hold up long enough for me to get some of my go-fast & CF parts out of the way.

I learned on another forum that the clutch is a 2 stage similar to the Tiburon's, which sucks & is expensive to replace, because of the floating flywheel, hence why I'm going aftermarket.

But, I also learned that there is a easy DIY fix for the soft pedal feel. You just remove a spring in the slave cylinder & refill the fluid. This will probably be my 1st mod since it costs nothing except for brake fluid & I can do it in my shop in a few mins right after taking delivery of my vehicle.

What would be REALLY nice is if Hyundai provided an upgraded transmission and clutch package for the R-Spec model. Who knows that could still happen. I should have asked Derek Joyce this when I had the chance.

 

[Tufast]

Hell yeah

Oh please Hyundai, please take the time & resources to make the R-Spec a truely light weight race worthy vehicle. Upgaded tranny would be sooooooooo awesome. Beyond removing un-needed BS, they could use a lighter materials where possible w/o increasing cost a whole lot.

Very great points, thanks guys. Obviously I have a lot of reading and catching up to do. GenesisBK.com just doesn't have this variety of information.

This is very true i was going to post that about hondas myself, A close friend of mine who i tend to help stage and video tape at the track made over 800fwhp in a t67 bseries coupe on a stock gsr transmission, he went [email protected] 1st round of Imports vs domestics this past year, 2nd round went [email protected] missing 2nd gear. Only time will tell.
