0-60
 
i know the 325i is slow and you all say theres no point in modding it but i wanna get my 0-60 down to at least somewhere in the sixes from the seven it is, which mods increase acceleration, at least a bit, and whats the fastest 0-60 you've all gotten on your 325i's? i know fast bob will be here shortly to criticize me, and someones gonna say search it in google, oh and im not talking about hp or torque gains, but im sure some mods come with it

the cheapest way to get u down from 7's to 6's is to do a 10-60 run :D
if u have 1k to spend, you can get a Shark Injector, ebay headers, go catless (if ur state allows u to do so), and if it's a manual, get a short throw shifter to shift faster through gears.
don't forget to change fuel and air filters, and get a set of new NGK spark plugs (if not done so). also get ur car checked for any codes for faulty sensors. do all of these at the same time and u'll feel a very nice difference in performance :thumbup:

I think most newbies that post here are high. Or drunk.

Remove as much weight from your car as possible and do your run on low fuel.

smolck 10-05-2012 06:47 AM

Auto or manual trans? Taller rear gears would be about the only way IMO (short of doing it with no fuel and no seats as mentioned above).

i read that alot, how hard is it to put either of those in? compared to clutch, i just replaced mine with a lightweight stage 1, which by the way also feels like it made a difference, and gave me the feeling that in put my cdv back in, itll take some getting used to, i still havent broken it in

Remove everything - seats, spare tyre - everything. You can also try using high-octane fuel. You can change your air filter too with a sports one. Removing the catalyst will also increase your power, but it's banned in most countries.

I always have to ask: why do you care what a stop watch says? Is it laughing at you as you drive? If its because you're loosing street races, either sell the 325i or race slower cars.

Lets cut him some slack. Whether 0-60 or just wanting to be faster, I think we can all understand wanting a little more punch.

If you replaced a clutch the diff is cake. Takes me about 2 hours now that I have done a few. First one took 3. Very simple. Just be smart and drop the rear sway bar out of the way.

Headers took me about 5-6 hours working slowly.

hate to be "that guy" but you can always sell the 325 buy a 330 and not really worry about it

Here`s the deal:

Your car is probably putting down right around 150 HP *to the wheels*....not bad, but not earth-shattering, either. You would probably need another 25 or so RWHP to consistently run mid-to-high 6s in the zero-to-sixty sprint, and as previously mentioned by the astute veteran `festers, the most effective solutions would be the combination of a 3.46 rear gear, eBay headers, and a free-flow exhaust system. Since excess weight is MUCH more detrimental to a low-horsepower car, it would behoove you to remove your jack, spare tire, tools, floor mats, CDs, spare change, etc..
All of the above would enhance your quest for a low E.T.

Which brings us to the issue of Driver Input:
Since a *lot* depends on this, you`ll need to play with tire pressures, launch techniques, shift points, etc.

Ultimately, you can *probably* achieve your goal.....

















(or you can buy a 330i :bigpimp:)

cant afford a 330 :/
ive been looking though, most of the ones ive seen have auto, which is the same speed as my 325, my buddy actually has a 330, same year as mine but its an auto, and i beat him, if it was manual on the other hand...

Interesting. A normal 330ci auto is about 6.5sec in the 0-60 area. Your car is more like 7.1 seconds so if you beat the auto 330 then your buddy isn't a very good driver.

i had several people drive his car because i thought the same thing, and i read that a 330 auto is 7 flat...



or im just a really good driver :D

Did some one say 0-60!?.
http://www.youtube.com/watch?v=ry2k2s6er6k

I've got them down to 4.5 without trying to hard now. and w/ 103 octane it's down to 4.2 ( If I shift properly ugh ).

oh and http://www.zeroto60times.com/ awesome site

ventsyv 10-05-2012 12:24 PM

330 is around 6.5. His car must not be up to snuff, if you know what I meant.
You can get carbon fiber hood/trunk lid, lighter rims, etc. You could probably reduce the car's weight by 100lbs fairly easily.
It's the lbs/hp ratio that makes all the difference.

Yup :rofl: so long story short. Get FI to get your times lower realisticly. Or take all your interior out and get a more aggresive diff. Lose any weight you dont need.

Or his car is not well maintained, noway a 325 manual would beat a 330 auto, i know how both drive, 330 would be victorious anytime
