I have a 1.8t mk4 jetta.. and I'd like to upgrade the turbo at some point as well as a chip and turboback exhaust. Just curious as to what the max HP a standard 1.8t auto tranny can handle without any problems.. thanks http://****************.com/smile/emthup.gif

Re: Auto max HP? (borajake)

HP is of little concern, tq is what you have to keep an eye on.
300 seems to be the general consensus around here. i dont think anyone has broken the 300 wheel OR crank torque mark yet. 275 or so has been hit without any problems http://****************.com/smile/emthup.gif

I have been running the ATP ST II/GIAC K04 chip for almost a year.

Dyno charts are coming. I am getting UP BT software and will post my dyno numbers b4 (K04 chip) and after with UP BT (if they will be able to make one)

Re: Auto max HP? (2OVTurboJetta)

the TC slips long before 300 ft-lb.
In a tdi it takes me right out of the nice part of the torque band, but it might be ok with you revvy gassers.
