I should be at about 250hp to 300hp.

 

Are you asking a question? or answering your own question? if so why did you post?

 

If you give me the material and shaft size and manufacturer process, then I can tell you an exact hp limit that the axles can withstand (ones of the perks of engineering ). But the main problem is the gear and joints.

 

I have seen stock B series axles handle up around 350whp for quite a few passes using 2 step

 

It also depends on how much the car is lowered, which can lead to failure due to joint binding.

 

its really up to how you drive the car. we have ran 10.89's on stock axles, with over 640hp 434 ft lb. never had a issue with braking a single factory axle

 

I will check the axle size when I go back to work on monday. But the axles are for an Acura LS trans mated to a B16A.

 

I was just kidding man, It all depends on how you drive the car. Are you planning on ripping it and ******* it all the time? If not, then you should be fine. Honda motors aren't torquey enough to snap them most of the time.

 

So being lowered with lots of hp=better chance of breaking axle?

 

The axles and placement of the axles are designed by honda to withstand the most load at those initial suspension geometries. Of course you have to take into consideration that your suspension also has free motion, but it's mainly designed for factory suspension specs. With your car and setup, I wouldn't worry about anything.
