0-60 time in a 325i

[dazleeds]

[quote="Wilson325i"]i really hate such threads and cnt belive am gona post in it but here is some thing to think about.

my best time in my 2.7 was 0-60 in 6secs with a 1/4mile 14.4@104mph and the worst was 6.8. on my g-tech, on 18" alpina reps, and on a lazy S3.64 diff, yep its true. oh and it gets to 60mph in 2nd gear

so well and truely with 15" bbs's and a s3.91, this thing should really fly LOl

oh and heare are some pics of the few runs that i did


^^the best, this is when i got the 6sec to 60

Damn them times look good mate
hope my soon to be built 2.7 gets as good

[SCOTT325SE]

sub 7 seconds CAN and HAS been done in a stock 325.










i know because I've done it myself.

My friend has one of those g-tech type timers, where you plot in all the info of the car, e.g tyre size, weight, run it smoothly up to 60 and 100, then coast back down. Its GPS monitored too, so its all counter-analysed.
We did 6 runs in my old SE and it timed back as 6.7seconds. I couldnt believe it, which is why we checked and did so many runs. My friend has a Renault 5 GTT Raider, running 170bhp at the wheels which does 60 in under 5 seconds (FWD sucks) and that runs this timer daily. We did a simultaneous launch and he was only a couple of car lengths ahead of me at 60 (R5 car lengths) lol so somehow, I do believe they were correct readings.

Sub 7 secs in a stock 325i IS achievable.... just make sure you dont mind abusing your clutch.

[Jesus325iTouring]

Has to be said,there is a vast difference between different stock 2.5's,my first one was a bag of nails but went like the clappers,my Tourer on the other hand would never have came close to it.
When Scott and I have dropped my new stock lump in i would be happy if it manages sub 4sec 0-60

[Jon_Bmw]

Perfectly flat road? Thes best way to do it I suppose, is do one run going, say, north to south, then the next south to north. Then average it. Perhaps my 325 just sucked, a true sub 7 second car to 60 feels pretty damn rapid.

that replacement lump will make your touring do 186mph Rog... uphill!

seriously though, that 5er engine will seem like a rocket if it goes as well in your touring as it did in the 5.

[kirils]

if i got a better start i could do it in 6 flat

dude when we you say 0-60 it's mph not kmh

[jonb]

I have a e30 2.7 stannard conversion (ex 325isport) was his son's car and has a full conversion reckoned to be putting out approx 215-220bhp I have an magazine with the my car in from oct94 it list's the 0-60 at 5.9secs and 0-100 at 14.9secs do you think these figurees ring true. thanks phil

i bet its quick, but i doubt the figures. i cant see it keeping up with say, an e28 m5/ e34 m5. as there figures seem to be around that mark.

I'm really sorry Scott, you are someone who's opinion I respect on here, but this is an impossibility. If I see this happen I will eat a shit sandwich. I don't mean G-Tech, or someones mate with a £1 wristwatch from a garage, I mean properly timed.

[dodgydodger]

i done a run at santa pod in mine at peformance vauxhall, i ran a 16.1 and had a fare old bit of spin at the begining! duno what the 0-60 is tho?? but i thought ild tell ya neway!
wanna shave loads of the flywheel and put a light cam in it with a six branch etc... but i wanna do a lot of things to all my cars! money aint the problem it the time as i have to do it all myself, as im a mechanic and race car preparation specialist it would be daft to give it to sum1 else!

[seanboy]

Crazyenglishman how much do you weigh?

[dodgydodger]

i dunno if im right here, its getting late but i went to pv show last year there were guys in 2ltr turbo vauxhall novas running 12sec 1/4s, now that is quick, thease guys are running at best 450bhp with nitrous or what eva,
then u take my m8 gordan appelton from wheelgame, who has a top fuel dragster running lik 2000+bhp he is runng like 7sec 1/4s
so take the time of a nova of say 12sec at 400bhp and a dragster at 2000bhp running 7sec 1/4s that means u have needed 1600bhp more to shave 5sec of ur 1/4mile time!

so things like putting a "zone chip on your 325 aint gunna barly touch the time of you 0-60.
and i dont wana start moaning but 325is are now well over 15yrs old, some are in good nock sum are in bad. sum have had recon engines, sume are cocke d up! how often do u change ur oil, do u flush the engine, every liitle help to the compression leading to a better 0-60! O and also what fuel u run! as that has improved tremendusly over the 15yrs!

at the end of the day, it down to the driver,the car,the tyres and evan down to the wheel size and tyre presures!
every1s gunna have diffrent readings and

[Davenotouring]

My Civic does 14.7/14.8 quarter miles, and 0-60 is high 6's, by estimation. I think it's probably more like seven.

A quick, standard 325i Sport will do a mid 15. (Oz's Tech 1) 15.5 for example, which is about an 8second 1/4.

If a standard early 325i will do a sub 7 second to 60 run, I will indeed eat a poo sandwich. If a standard, late 325i does, I will eat two poo sandwiches and drink a glass of urine with ice.

that would be funny to watch
a bit like magners but makes you pull a sillier face

erm 15.3 Dave, get it right ffs oh and dont forget i cant drive!

[Davenotouring]

Sorry mate!! Did you do a 15.3 really? Oh bugger, I can smell the poo sandwiches already!

[oguz327]

lol check the santa pod website

To be fair my sports not standard, few tweeks and stripped but your civic is still quicker!

[dazleeds]

this is a challenge i need to consider

[carpmart]

Interesting thread.

A few comments/observations from me. I have just bought a 325 e30 86 vintage which I will take some weight out of, lower to drop the centre of gravity, polly bush, fit the lightest rims and tyres I can to reduce unsprung weight and balance as best I can via setting upfrom a corner weight perspective. This will be used as the winter hacker as my fisher fury kit car with aero screen is just too cold to use through another winter. If the e30 is even near to a 7.5 second car I would be surprised but who cares? Quick cars are only quick with people driving them who know how to make them go quick. Other than a drag away from the lights 0-60 has little relevance! The ability to carry corner apex speed, brake, turn and accelerate is what in my mind makes for fun with a car.

My fisher fury has a blown pinto engine in it. It weighed 537 kgs last year and was rolling roaded at 148 bhp at the wheels, so not too different from a 325.

I can only get a mid 5 second 0-60 with this but the torque of the blown engine combined with little mass makes for explosive overtaking acceleration.

My points are this

Power to weight is what makes for a quick car.
Torque is where its at!
Unsprung weight makes a big difference to how a car handles
0-60 is not impotant to having fun!

Just my tuppence worth. Rambling on as usual! In summary, no way will you get sub 7 second with a standard 2.5 e30!

[quote="seanboy"]Crazyenglishman how much do you weigh?[/quote
i have no idea of its wieght,
but i should be doing a timed 0-60 run on the 4th dec so will let u all know what i get
good or bad

[Speedtouch]

So, what was the result...?

[--alpina--]

i reckon, the result for this speed in the 325, either he bought a resister that he fitted in the air flow meter or he drove of the cliff with a hot rod parachute and calculating the 0-60 then...OR theres some sort of crack snorting going on...

[fuzzy]

So, what was the result...?

it wont be anywhere near 6.5 thats for sure

[northloop]

. My friend has a Renault 5 GTT Raider, running 170bhp at the wheels which does 60 in under 5 seconds (FWD sucks) and that runs this timer daily

I would like to see that verified. 170bhp at the wheels is something like 220 at the fly? To get a car like that with fwd to 60mph in under 5 seconds would be something of a feat.

[fuzzy]

i was out yesterday with the stopwatch trying some unofficial 0-60's,it was wet so traction from stationary was a bit of a problem but the quickest i managed was a 6.7 i was going to 65 on the speedo to allow for the 10% reading difference.i reckon in the dry and with some more practice i should hit 6 seconds.i have 292 bhp,i dont think a standard 325 could do it in 6.5 even with jenson button at the wheel

[maxfield]

fuzzzy there are too many variables to measure the right time with a stopwatch like that.

like i said its unofficial just to get a rough idea.the only variable that makes a difference is wether im managing to hit the stopwatch bang on and get my launches right,everything else counts as conditions are as they are on any day

[Andyboy]

A 325i does 0-62 mph in 7.4 seconds - that's the best time ever recorded by Autocar. An early 200 bhp M3 won't quite crack 7 seconds. These are times taken by professional road testers with proper equipment using fresh and properly run in cars - not some scratters with an F reg shitter on the Slough ringroad with a mobile phone stopwatch.

As for some shitheap Renault 5 with 170 bhp doing it in less than 5 - yeah, righto................

This is always an interesting debate the old 0-60 time. Sub 5 second 'road' cars are rare beasts. Don't get taken in by all the hype around people quoting 0-60 times of x secs for their car! The usually are waaaay off being true!

The renault 5 is possible to get to 170 bhp at the flywheel running reasonable big boost figures but unless this is a fully re-built, low compression, ballance bottom end etc etc there is no way you will get 200+ flywheel therefore 170 front wheels. There is also no way you will get the car much below 750kgs.

I have 148 measured at the rear wheels on my kit car with a pinto turbo. I can just about do a low 5 sec 0-60 but would never do this regularly as the clutch is lunched very easily even though my car weighs less 537 kgs

There is therfore no way, using a very well measured benchmark, that a sub 5 second 0-60 is even remotely possible in the renault!

[Speedtouch]

I personally wouldn't even bother attempting to measure a car's 0-60 time in the wet...a complete waste of time and fuel if ever there were one

[northloop]

That's where I was coming from carpmart

Cars like Subaru's with over 300bhp can break 5 seconds but the method is brutal. Dial in 6000rpm drop the clutch and let the AWD sort things out. Achieving the same in a FWD R5 would be very very difficult. You would need 3 tonne of ballast on the front wheels holding them on the tarmac me thinks.

At the end of the day 0-60 is a useless figure only ever achieved by test drivers killing cars so they can make the benchmark claim in a brochure. It's pointless in the real world

0-100 is what separates Men from Boys. Any car that can beat 15 seconds to the Ton is very decent.

[whiterhino]

renault 5's were quatermile kings dont get it twisted.gt tuning and the likes of bb tuning prepared cars fly.i should know enuff said

[Turbo-Brown]

Think the 0-60 holds relevance myself.

I know my car's not as quick to 60 as an E46 M3 and no small part of that is down to me being soapy.

However, remove the skill of a decent launch from the equation and go for in gear acceleration and off I romp.

Which is the quicker car though? The M3, as real world driving (and driving on a track I guess) involves repeated acceleration from low speeds.
