Default tranny options for 550 - 600 hp in a usdm wrx??

.......550/600 to the wheels, not the crank. i am looking into the new gears that will be offered through turboxs. i have gotten alot of info from nathan and they are being run successfully on 10 second impreza's in australia. but i thought i'd see what anyone else had to offer. i am not looking for a sti tranny, i am looking for dog box type set up or even info on an auto tranny. who has what to offer???

Exedy twin disc Carbon-Carbon will hold 750hp and "over 500 ft lbs. of torque" And they are pretty as well.

haven't seen it yet. nathan has some at turboxs and i'm hoping to go up there and check them out next week in person. straight cut gears and rated at over 800 ft/lbs of torque from what i understand. don't know too much at this time. longer first gear, shorter 2nd gear. they are running them on phils car right now and a 10 second wrx in australia.

My guess is that you better be looking at axle and diff upgrades while you are at it. Cobb busted the rear diff with 420whp. You are going to need a Quaife up front and probably in the rear to control wheel spin. I know some of the high power guys have broken their axles too. I saw an axle set that was rated for 1000 ft-lbs but I don't remember if it was on NASIOC or Club WRX.

yeah, i am planning on that, there are alot of options for diffs/axles.....but its the tranny options that worry me. seems alot of people offer gears for 300-400 hp but not many people offer anything for 500-600.

No prolem... this was the email then sent me:

"Rich,
Yes, we make a 5 speed dog change kit for the Subaru. I have attached some information about the kit, and a ratio chart for the gears we are making at the moment. These ratios are ideal for drag and circuit racing, and kits with them they will be ready for delivery in early May. You can purchase these kits directly from us for AUD$9700 (about US$5800). We can arrange express airfreight to the US for an additional AUD$260 (about US$160). We usually require a 30% deposit with your order, and the rest on completion, prior to shipping. However, if you want to go ahead, there is not much time between now and early May, so you may want to pay the whole amount up front to avoid two sets of charges, and any delays that could occur. If you want one of these kits, I have attached our bank details, so that you can arrange a funds transfer to our account.

Please let me know if you have any more questions.

Regards,

Ross Cureton"

there website is www.holinger.com.au

the box's picture is pure beauty!

Rich

they also sent a few attachments...like a letter, a gear ratio chart, and something in a .xls format

Prodrive 5speed dogbox. 5 forward gears in a 6-speed case. They are very large and this is the third or fourth generation of this dogbox design a lot more reliable than the original dogboxes (the ones introduced with the NAI bodystyle). If you need more info just let me know.

JUN's car has 650hp and uses the stock 6-speed tranny with upgraded clutch. It seems it indeed holds.

Default anyone make synchroed boxes?

from what i hear daily driving a dog box is a pain. it only wants to shift fast and grinds if you dont...plus the double clutching you would need to do. is there a box that isnt a pain in the arse that can handle the hp? i guess a smooth shift wasnt a concern if its not strictly a race car?
