Looking for 350+hp out of my A8 and all that iove heard is that the engine is capable (4.2 quattro, its a 99) but that the tranny cant handle it, what choice do i have to get it to wher eit can handle it?

skiwi

tranny can handle it. the one in the s8 handles 360bhp

I reprogrammed my transmission like the European S8 (quicker response out of the A8)

(the wheels/tires are for sale)

and the 360 hp S8 is 317 ft-lb @ 3400 rpm.

How much do you want for for the wheels/tires? What is their condition?

I Guess i shoul dhave been more specific, i need it to handle 400+ atleast, closer to 500

I have bumped my hp with an exhaust and thinking chip too i just need to know if the engine/tranny will hold up to it all.

you're probably beyond it's torque rating and in unknown territory. I expect that there's little that be done to the tranny itself, but I would certainly install an oil-air ATF cooler in series with the existing oil-water ATF cooler. If you use that HP, the torque converter and transmission (and motor) are going to be dumping a lot of heat into the radiator.

Well im asking because the company i work for my boss and I have decided to get my a8 out on some tracks for some publicity (a small home based computer building company, pretty much i wanted money for my ride so we came to an agreement hehehe) and so long story short im going to be trying to pull ~500bhp naturally asperated. Which is why im wondering what will be happening tranny wise, would an RS6 tranny work at all? or are we dipping into welding and firewall destruction heh. If thats the only option to have it handle the power.. i guess ill be savin my pennies for awhile heh

ryoung

I have no idea whether the RS6's tranny is altogether different than the A8's or just modified.

BTW: Where are you located and what tracks did you have in mind? Perhaps I could join you.
