E30 Zone

Ok acording to performance bmw mag the 0-62 time for a e30 325i is 8.3 seconds.
I have only stipped mine out and done a timed run and got 6.5 seconds and my start was not the best as i did get a fair bit of wheel spin in 1st gear, ive now fitted a KnN air filter and believe if i got a better start i could do it in 6 flat.
This sounds to good to me but it clearly is not as ive done it , unless the standard times are not correct ?
Has any one else done a timed run and if so what results did you get?
cheers

8.3 is about right.

6.5 no chance mate. Sorry.

I will personally give you a medal if you do 0-62 in 6 seconds in a 325i.

Need about 230bhp+ in an e30 i think to do 6 seconds flat.

sorry to say this people it done it and willing to show anyone local to prove this. if any one has theres stripped out it would be good if they could have ago to compere

How did you time it?

the computer stop clock in the car.

6.5 secs mmmmmmm, is your car standard, apert from being stripped out?

yea completly well as far as i know but since then i have a KnN

santa pod sunday fella

time the qtr then work it out from there
cos 6seconds in an e30 would be one hell of an acheivement
dnt think the obc timer can be accurate fella

yeah it cant be that far out, could it?
im going to the pod on saturday but prob wont be doing the strip as im hopping to go on the drift arena again

Your speedo is probably out, as is your timing.

Sorry. It's not gonna happen. Anything under 8 in a 325 is quick.

ok then i hit 60mph in 3rd very soon after changing from second. ( Does that sound like 60 ) timming was spot on, ive had a few fast cars in the past and agree the 325i are no rockets, but i know its doing it under 7 seconds if you want to allow 0. 5 of a second for stop clock being out and timming, But i might now do the strip test at the pod just to see, will that give a true reading?

It still won't tell you an exact 0-60 time. You will be able to work it out roughly from the times on the printout.

They do 0-60mph tests at some shows, like TRAX.

When you time yourself you never get the same results as the pros and its usually less. The 0-60 times for a 325 were around 8 seconds from a variety of sources and bear in mind these cars were new then and making the stock power.

I think that only the fittest E30 driven by the most commited/co-ordinated or downright unsympathetic driver could hope to better anything in the range of 7.5-8.5 secs.

Even if ate sevens may have been possible in the hands of a road tester when the cars were new (subject to gearing and driver brutality) most 2.5 E30s are prolly betwen 10-20bhp down on the quoted figues these days through age / poor maintenance.

Plus drag starts are a difficult to master, vary wildly according to conditions and largely irrelevant in scheme of things.

In gear acceleration (e.g. 50-70mph in 3rd / 4th etc.) is what you'll notice day to day.

to get the magazine figures, the test drivers would have the revs at 4000 or so, then slip their foot SIDEWAYS off the clutch; if the car/clutch/engine broke, BMW would supply them with another car.

lol, i will give you a certificate if you do it in 6 seconds!!!

me
ill be trying to buy your car

well all i can say then is my speedo, obc, and timming must be out?
I would like to take it on a propper test to see, But i do know that stripping it out has made a massive difference to the acceleration, More then i had expected any way

checked the speedo on mine last week against the satnav and
mine only reads between 3&4mph over on the clocks

better than i expected tbh

oguz,s tech 1 is all stripped out maybe worth seeing if he fancys timing his and compare

but he does have the btb/bbtb/itg filter fitted and recent remap =204bhp

The best i managed in my 328 sport was 6.18 seconds and that was pushing 218.3 bhp

Take it up the pod, if it'll do under 15 secs quarter then it may be close to 6.5 seconds to 60. I bet you'll do about 16.8 though.

no way can u get 6.5 secs unless you do some engine work in addition to making your car lighter. Take it on the pod see what you get on the quarter mile.

No body's asked how much weight was removed from the car in question.

My gut instinct though is that if Scot's 328 with 260bhp managed it in 6.6 and I with 270bhp got 6.3 then it might be a bit optimistic.

However, every 100kgs lost is said to be equivalent to an 80bhp gain which would put it on a fairly level pegging.

If this were true a light weight two door no electrics etc would be a hell of a lot quicker than a fully equipped four door (there is at least 40 kg's difference) and there not in my experience. Anyone else care to comment?

I got a 7.3 second 0-60 out of my '88 325iSE in standard form apart from K&N filter element. Then I put one of the E30Zone Mild chips in and got a 6.7 second 0-60 time. This was on a dry road, cool evening air. The car doesn't have LSD. (Timed with the obc stopwatch.)

that can't be right 80hp for -100kg

No one has actually mentioned that a K&N won't drop the time by 0.5 second.
It will make it sound a bit throatier but make no difference to the time.
Sorry fella.

When will people learn that there are just too many variables with regards to timing yourself, using a stopwatch and taking the reading from the speedo??? I own a modded 328i e36 with 230bhp, and a fully stripped e30 325i for a track car with a scorpion exhaaust, Induction kit and a zone chip so i do have experience of quoted vehicles. The e36 is really quick, and i'd say up to 60, is quicker than the 325i i've got, however, the two five does feel bloody quick TBH. It wouldn't suprise me if a stripped (and i mean unsympathetically stripped )2.5 with a decent engine and a good launch could hit low 7's to 60. Anyone got an older PBMW or Total BMW??? check them out and the times in those differ greatly. they actually quote the e30 325i as 7.2 0-60 and a e36 328i at 6.4, not 8.3 and 7.3, who's telling the truth, they've changed their mind once already!!
I know people who've used gtech meters on their e36 328's (admittedly still not deadly accurate but much better than a stopwatch) and got low 6's

I always heard it was 7pounds = 1BHP gain
since 7 pounds - 3.175kg
100 kg = 31BHP gain

However reducing sprung weight, ie the weight around the axles (wheels/tyres/brakes/hub ect ect) is worth approximatly 3-4 times more than unsprung wieght.

This is the very reason racing teams especially F1 make such a big deal out of weight though.

You would have to loose an awful lot of weight to get a 325i (circa 170 bhp for arguments sake) to the ezuivelent of 230bhp - approximatly 200kg's.

And IMHO and I have said this on more than one thread this week the K&N is more than likely gonna loose you power or not alter it at all!, Waste of money.

A zone chip won't give yo enough gains to loose 0.6 of a second either, a zone chip is worth roughly 10bhp (wild and dependant on other mods)

10bhp will not loose you over half a second on 0-60!

Losing weight alters the power to weight ratio.

If a standard E30 325 weighs (roughly) 1150kg with 170bhp it has 148bhp per ton.

Same car weighing 1050kg would have 162bhp per ton.

To get the equivalent of 80bhp more it would need to weigh 783kg!

Weight saving, in my opinion, is about the best modification there is.
Mainly because it is free - or even profitable if you sell some parts you take off!
It also helps cornering, braking and fuel consumption!
