    06-07 gear hp rating

    does any one know the actual hp rating of the 06-07 gears?
    please no speculations.

    i was told by the my dealer mechanic that it was rated for 350hp (crank) but i wanted to be sure, and i some how doubt this is the case.

    It's all speculation.... No matter who answers because everyone drives differently. But 350 to the wheels is pushing the stock tranny to it's limits, I wouldn't say it's safe to push this much.

    regardless of the way you drive, mechanical parts in a car's engine and moving parts all have a certain HP rating ( meaning they are able to handle this amount of power and not brake under normal driving condition for this amount of time)


    and 350 was to the crank i never said to the wheels.

    ppg gears i believe are rated for close to a 1000hp ( i could be wrong but i remember some insane numbers for them when i was reading on it.)

    When I had the car tuned with the VF39 it made 318WHP//370WTQ. That would put me around 380 crank horsepower. I put 20k mi on the car after that with no problems. Then, I got the car tuned with the 20G and made 367WHP//380WTQ. Which is about 420 crank horsepower. I drove the car for only about 1k mi. and then slapped on the STi drivetrain.

    I took very good care of my wrx transmission, doing little things like adding syncromesh fluid, rev-matching, and easing the 1-2 shifts. Honestly though, it's all in how well you treat it.

    It absolutely matters how you drive. If you have a 350 HP car and you drop the clutch from 6k RPM versus letting it off slowly of course the transmission is going to break faster. You can't measure the strength of a transmission in HP for exactly that reason. HP is a measure of power, not force, and force is what is going to break a transmission, not HP.

    Two questions;

    1) Did you change trannys because the 5spd broke?

    2) If strength wasn't an issue, would you have kept the 5spd? (in other words, which one was more "drivable")

    sorry my bad what is the torque rating... again i am not asking if i put this much power/torque will it brake or if i am driving like that will it brake or is it going to brake.!!

    all i wanted to know was if some one knew the actual torque rating of the 06-07 gears because believe or not when some one build pieces for any mechanical device ( cars specially) they all have an actual rating of how much they can handle.

    nope tranny still intact... i just wanted info on how much torq the gears have been rated for which i know is not that weird of a question. if i had the money i would get the 6speed no question but that has nothing to do with what i was asking

    No, the tranny is fine. My friend is swapping it into his 03 bugeye.

    If strentgh wasn't an issue, then definitely yes. The five speed IMO is way better for daily driving and highway driving too. With the 5 speed in 5th at 80mph I was riding right at 3k rpm. With the 6 speed in 6th it's around 3270 rpm. So there is better gas mileage with the 5 speed also.

    Oh I forgot. To the OP I'm going to say this again because you seem to have not read it. I'm sure 350 crank horsepower will be fine for the tranny. I rode my car with 380 crank for 20k mi. Went to the track a couple times and engaged in spirited driving here and there. The tranny is absolutely fine. But again, it's all in how you take care of it.

    thanks for the info, but thats not what i was really looking for...
    i know it depends on how you drive it... i was only asking to find out the actual torque rating spec of the gearing which i am 100% sure must exist some where. maybe the company who build them which by the way, does any one know who builds the gearing for the tranny on subaru cars?

    subaru is never going to release what the stock gears are rated too. they are rated to stock power levels and that is all.

    subaru would have way too many problems if they said the gears are good up to 300/300 and then someone broke something on like a stage 2 setup.
