    Reliably? I would say a 150 shot. Stock bottom ends can take a lot more, just won't last forever, but what does? That's assuming the fuel system is up to par and everything else.

    Can the stock tranny and rear end handle the 150 as well?

    the rear and tranny are a touchy subject if you ask me. I dont think the rear will hold 150 shot if you spray it out of the hole and the car hooks. I have seen rears break from high rpm clutch dumps let alone n20. As far as the tranny's (4l60e) they dont hold worth a shit no matter if god himself wittles one.

    Is the car an A4? Cause the t-56 in the M6 holds up great. Rear-end don't though. I got 420 to the wheels and destroyed the rear-end day one.

    175hp NO PROBLEM!!!!!
    Just need to have a good fuel system that can supply both the motor and the unit with steady fuel pressure......And a good tune, timing is the key!!!
    I have 2 cars that have been spraying 175 one for a year and a half and the other 2 years no problems yet.
    Both cars are autos with 175 right out the gate on 17" drag radials.
    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    Trans casing is good for around 850 hp. Components inside, I have no idea.
    Bottom end is good for more than that. There is one here in oklahoma city with 626.6 RWhp. Factor in 15% loss and that is a little over 700 hp at the fly.

    Roughly 735 Crank Hp, and that's assuming a well rounded system. If he doesn't have underdrive pulleys, or if he has a 9 inch or even a 12 bolt, you're looking at a greater loss. Chevy hi-performance found a 30% loss through a M6 using a 9 inch.

    I am not sure on what his rear end was. I think it was a moser 12 but I am not for sure. I know he had a slp underdrive pulley. He would say too much, he just showed me the dyno sheet after he ran.
