how much power should i get

anyone with impact gun exp id appreciate a pointer....
since i dont have one yet obviously everything on my car that ive worked on has been with my hands, but i wanted to get an impact wrench just to see if i could make things a little simpler when i have a lot to undo and do back...my question is do you think a 250 ft/lb impact gun would be strong enough to take off any nut i need to on the car, or maybe on the otherside could it be too strong; [overtourquing ]...not for any particular project, just want one as a plus to ease the job

250 would be more than enough! i don't know about the rest but i know that the bolts on the rims only need 80 pounds of torque!

i believe the crank pulley is like 100ft/lb nescessary to remove.
as for rims, rule of thumb is 90-100 i do 105
if you get a torque gun try to get something a lil higher maybe 300 350 just so its easier on the gun, dont use it on everything though, youd be surprised how many things need to be torqued down to a specific rate and how much damage you could cause if you dont pay attention, as for overtorquing there are torque sticks that will limit the amount possible for you to apply. plus there are settings on impact guns, be carefull when removing nuts though if its rusty buy some penetrating lube to break the bolt free or youll snap it, and always ask honda dealerships what they recommend for specs on torque on any bolt your unsure of, get a quality snap-on, mac tools, craftsman, etc. name brand clicking torque wrench that is 1/2 inch drive with a range that is pretty high then get a 3/8 inch drive one with a lower range

2 things here.

first to the original poster,
i'd only use the impact wrench to take things off, and maybe initially put things on. for things like lug nuts and other parts, you NEED to be certain of what lb/ft you are applying as improper torquing can cause damage.

do NOT use 110lb/ft on your lug nuts. you could warp your rotors or stretch the bolts, causing failure down the road. also if you don't torque them each to the same lb/ft you can warp the rotors. 80lb/ft is correct, but you could go to 90lb/ft (which is what I do)

10 ft/lb wont warp rotors, maybe it isnt nescessary but it wouldnt do that much harm, doin like 150-200 might do it though
edit: nvm i thought recommended for our cars was 100 not 80

250 should really be enough to take off anything.

with air tools, I'd recommend a good brand name... Not some **** you can buy at walmart. Because, they are going to be put under major stress. You want something that is going to hold up.

some good name brands for tools, and ill list a few common bad things about them
snap-on, great quality but expensive
mac tools, not as good as snapon but they hold up well personally theyre ratcheting wrenches are best
craftsman, high quality with good price and easy to get service at any sears... theyre ratchets are ok but after a month of use they have noticeable wear and tear and feels loose
bluepoint... its just a cheaper company made by snap-on (or craftsman i forget but both make a cheaper brand also)
matco, havent used them but never heard any real bad things id say theyre not bad.

all in all i left out a few just cus you dont need every company and the best i would suggest is craftsman because its easy to buy and service as opposed to other brands cus you can just run to sears. one of the good things is i guess there is some card u get and you save like 20 percent on sundays or sumthin i forget.

youll be paying too much for an impact gun with 250 ft/lbs, you dont need it. if you are working on a sherman tank, or a bank vault, then yes you might.

Snap-on is junk(imo). My pops and I use mac. But for a starting impact cambell allthough cheap will last you through the learning how to use stage. Like air care(if you will),water seperator and proper oiling and storage. As for the torque rating ya 250 is more than enough. Nothing on a vehicle should be more the 150ft/lbs. But with some older cars rusty dirty bolts does add to the power needed to romove. Also the fact the you need to learn to put bolts on with the min. of power in a impact do not just slam a bolt, nut or whatever on with an impact you will cause alot more trouble. Another good tool to get is a good torque wrench.

torque wrench and air rachet, thier, problem solved.
Besides, I dont like using any air tool that has more torque than my honda, which eliminates almost all of them.

dont forget that a good dry air compressor or a water seperator is a must if you get a nice wrench
