0-60 in 7.0sec in 535i 5sp?

[fatcat55]

I've been keeping an eye out for an E34 535i 5sp... am looking into a couple right now.

Is it possible to get this thing to 60 in 7 seconds without FI?

Im seeing theres not a lot out there...

S&K, EAT chip: 15HP
Exhaust: 8HP (woo.)
Dinan Intake Manifold 9HP
Clears: 1/2HP
________
32.5HP

Now per my calculations (yes i pretty much pulled them out of my ass but only sort of) it would take an extra 37HP to get the 208HP 535i to 60 in 7 seconds.

So..... We need 4.5 more HP. WHERE??????

Some undertuned pos FI for under $2,000 would work too but so would million dollar bills falling from the sky.

[jimmyz2]

I have added RD headers to the equation.It makes a nice hp increase.And I will bet $5.00 I can get my 535i 5 spd under 6.4. :)

535 6.4 with no FI? $5.00 isnt the bill of confidence.

goes to show what an E34 mod n00b i am. ok a car n00b, whats a header?

So how does the mod list on your 535i go with prices?

Headers replace the exhaust manifold

here is some reading for ya(for v-8's):

The exhaust manifold, usually constructed of cast iron, is a pipe that conducts the exhaust gases from the combustion chambers to the exhaust pipe. It has smooth curves in it for improving the flow of exhaust. The exhaust manifold is bolted to the cylinder head, and has entrances for the air that is injected into it. It is usually located under the intake manifold.

A header is a different type of manifold; it is made of separate equal-length tubes. Four tube headers will slightly out perform three tube and Ram Air manifolds, and the three tube headers and RA units are a little better than stock manifolds. However, most standard exhaust manifolds found on Muscle cars are relatively efficient, and do not hurt performance as much as the aftermarket would have you believe. The headers should have 1-5/8" primaries for most vehicles, while higher performance street/strip cars may run slightly stronger with 1-3/4" primaries

interesting. So I just read on bmwe34.net that the Hp increse for RD headers is 7hp (modestly). Is it more important to upgrade the exhaust then once you upgrade the headers?

the mass airflow meter (5HP) sounds intereseting...... differential is tempting too but like FI its not something i believe in... :nono

[Johnny540]

You don't believe in a better differential or forced induction?

...what?

If you throw in a higher geared, limited-slip differential, you'll see a huge improvement in 0-60 acceleration.

Also, look at the tires you're driving on. It's the only thing that touches the road, and often the most overlooked thing.

It's all about traction.

[Gamite]

the stock rating for a 5spd is 7.1 seconds, so I would say its VERY probably, esp since u'r chipped.

BTW, you can't add horsepower like that, its not just a simple adding equation. The only way to know for sure is a dyno.

[323I Junkie]

Dude, mine has nothing but I Dinan chip and Ill put a $100 bill on the fact I can row it to sixity in under 7

[bähnstormer]

just slap a 3.64 or 3.91 diff on there
mine prolly does 6.5 with just chip and
diff

[323I Junkie]

Dont you guys ever take your cars to the track and get some accurate info?

[bähnstormer]

what're ya callin me a liar ?

heheheh - hells no my car is made of rubber
and i don't wanna pay to beat on it =]

[fatcat55]

According to the book BMW Buyer's Guide which has full specs on just about every BMW ever made, the E34 535i 5 speed gets to 60 in 7.6 seconds. The E34 530i 5 speed gets to 60 in 7.5 seconds.

Where are you guys getting 7.1 seconds?

[E34nication]

mid to low 6's with minor mods in a 5-spd 535 sounds a bit far fetched to me... probably better off talking 1/4 mile times since those are easier to come about. Who, with a 5-spd 535, has taken his/her car to the track and what kind of times did he/she get?

[fatcat55]

who cares what ppl think they can mod these things to how in the hell can you claim a 535i 5 speed gets to 60 faster than 7.6 seconds?!

Dear Rocket Scientist:

I believe it means a stock 535i 5 speed is reported to get to 60 miles per hour in seven point six seconds, no faster. Anybody claiming otherwise should provide support for their argument.

before you go giving me guff about being a rocket scientist you should check your post and see that it is a run-on sentence that really doesn't make that much sense. Put some punctuation in there so we know what the hell you are talking about and don't give me a hard time for not understanding your ghetto-ass posting style.

Dear ghetto-ass:

I'm not the one who claimed to be a rocket scientist. You better go look up my OT track record before you try and pick an e-fight with me.

[Dwayne]

The manufacturer's 0-60 time maybe be different from another source's (such as a magazine) 0-60 time. One might claim 7.6s, the other might claim 7.1s. Chill out.

EDIT: I guess you just got in a post before this one. Your OT record sucks, not sure how you think it'll help you here.

first of all... please point out where I claim to be a rocket scientist... second of all i don't understand what your OT track record has anything to do with anything. I just think you are another 17 year old that needs to stick to the 3-series forums.

[Andryuha]

maybe because he tried it? :dunno I must also add that the actual 0-60 number will be different from the one in the manual and it would most certainly be slower. This is due to the facts that driver error will occur at some point, and that cars tend to lose some of their drivetrain characteristic as they age (wear and tear in the engine, tranny, and diff0

[bähnstormer]

stop it, the both of you lol..

the bmw owners manual claims 16 sec 1/4 for my car...
i have a car n driver review from 91 of my car with
a faster time.

with my mods and my butt sensor i think i can do sub
7 second runs to 60....but who really cares about htat?
its all about corner exit speeds baby!

Why are you being such an asshole? Why would you even mention OT? All you can do is bring up false accusations. Yes, i still remember how you made up that BS about me being in favor of Adeel's inprisonment. Grow up. People have actually tried to help answer you questions, and you are starting this nonsense.

I was feeling attacked. :(

Well the reason I'm so set on 7.6 is becuase its a published book on BMWs (not a mag that might have sponser $$ or BMW's website bias etc).

But I would be very interested to know what mags reported what times for the sock E34 535i 5 speed if anyone has any.

Just once or twice wont hurt :evil2

[Dark Helmet]

did anyone mention gears????

also, my 83 533i was rated 0-50 in 5.8 (0-60 in 7 can't be too far off).... but you E34 porkers have an extra 600lbs to pull....

[stuntride]

its startin to get hot in this thread

my source said it takes 10.4 seconds to go to 0-60 but i think he only had his pedal half way down, and hes been put in the slammer twice for fraud. theres not really anyway to back up ur theory except get in a 535 and go find out for yourself

[epj3]

But we have the cams from the euro e28's m30, and also have a bit more power from the 533 :redspot :redspot (Though we still have that fat ass...)

This whole argument is rediculious. Arguing over what a book says vs. a magazine. Lets see, what could cause a .5 second difference? Well, a few things off the top of my head...

-Air temperature that day. I believe every 10 degrees of temperature difference of the air going into the engine equals about 1 hp +/-. Not to mention tires won't be as grippy in cooler weather.
-Air pressure or elevation of the test
-Tire pressure. Did they have 60 psi of pressure in the tires? Maybe they had 20 psi of air in the tires.
-Launch type. Did they drop the clutch from 5,000 rpm laying 25 feet of rubber? Did they rev to 1000 rpm and slip the clutch to get the car started before flooring it? Did they launch it a proper way?
-Did the test car have a limited slip or not?
-Biggest difference obviously is the driver. Did the driver granny shift? Anyone ever watch car shows on speed where they test drive cars (US Shows)? The old guys granny shift. Can you really compare their granny-shifted time to a time by someone like tiff needel?
-Did they shift at 5,800 rpm? Did they shift at 6,250 rpm?

The e34 is DEFINITELY faster than my 1988 325is was. The 325is had a near perfectly tuned motor at the time - and the e34 is still faster to 60 than the e30 which was rated 0 - 100kmph (0 - 62 mph) in 7.5 seconds according to the owners manual which i have sitting right here. The e30 had an extra shift before you hit 60 (2nd went to something like 58mph), too.

Really - this thread should be moved to the e30 or e36 forum. I've enjoyed reading and posting so much more in the 5 series topics than the 3 series. MUCH less arguing, no smartass responses, and you actually get real help with what you WANT to do - not suggestions of what you "should do".


Buying a bmw to be a fast car 0 - 60 is stupid anyways. I think ford makes a car to do that.

well to be honest im trying to talk myself into the E34. It doesnt handle as well as the E46 323 im looking at. not as fast. im losing the battle with myself. :( plus my friend told me it was an old person car.

sigh.

im never going to buy a car.

E34's are hot, anyone that tells you otherwise probably drives a Cavalier.

sure but hotter than E46....

maybe not :dunno

[Brewster]

I don't know if I would say hotter than an E46, but certainly on par for a 10 year older design.

[Andryuha]

Well, to each his own. I, for example love all pre-bangle bimmers, except maybe the 318ti (because of the lack of trunk). I got E34 because I got a good deal on it, plus anything newer was out of my price range, since I really hate being stuck with car payments. Anyway, if you have enough money for an E46, then you probably could afford to buy an E34 and mod it to the point where it will outaccelerate and outhandle the E46.

PS, no hate intended by my previous posts - just tried calming you down :D . I don't really take any offense to anything said to me on the intraweb.

[sdwhitney]

Buddy of mine in the CCA here has a 90 535 manual like mine, but with all the bolt ons, EAT chip, gauges, exhasut, intake, suspension, but probably not over 10 grand in the whole machine

His car will smoke ANY e46 ive ever seen, and could beat a e46 323 starting out in 2nd gear

Old person car? If it matters that much to you what your firends thingk, why arent you letting them pick you out a lancer or something

i used to beat my buddy's 323 5-spd with bolt ons in my '99 acura 3.2TL... plus you see about 500 e46's a day... definitely doesn't make it a bad car, i just like having something that isn't seen as much. Oh, and I flat out roast e46 323's :evil2

haha...grammar wars rule! You have a run-on sentence too. You have two run-on sentences.

[epj3]

I think its funny someone comes in and asks a question about a car. People answer, and then the original poster argues with the people who actually OWN, DRIVE, and WORK on the specific model. Then it's called an "old man's car". No offense, but when I think of an old man's car, I think of a buick, or maybe a big mercedes. Not a BMW. But if my car is an old man's car, then I guess there's no reason to put $1000+ into the suspension, beucase in the end, it's just an old man's car.

[E34nication]

^^^dude you got a V8, which without a doubt will own a lot of cars out there, but he was talking about a 535i.

yea but i just don't think he should really be talking about 0-60 on a 535 in comparison to a 323. 323's are pigs from my experience. I would think a 535 would walk all over one.

The fact that I used to beat my friend's in my TL (which btw hit a stunning 15.8 at the track) doesn't say much.

[323I Junkie]

YEah, comparing the 323 vs the 535 is redicuolous

the only e46 non m ive seen comparable is 328 manual or 330 manual

[tjn182]

Back to original post --
If not already stated (I didn't read all posts) - You can install a shorter differential. It would decrease the length of your gears allowing you to accelerate through them faster... that would DEFINETLY pop you at the 7.0 second mark. My old e28 did 0-60 in about 7 flat w/ a 3.73 rear end, chip and intake.

[E34nication]

haha...grammar wars rule! You have a run-on sentence too. You have two run-on sentences.

Are you serious?

[bähnstormer]

stop with the grammar guys
its silly

yeah like i said i have gears and a chip
i can prolly do 60 in 7 or less


BUT ITS EXIT SPEED THAT MATTERS

[jimmyz2]

In my 535i 5 spd.,I can chirp my tires in 2nd gear with 2 200 lbs guys in it.It goes fast enough to get me a speeding ticket.

[323I Junkie]

Whats amax=zing is the 93 to 94 1/4 mile trap speeds Ive heard from these cars, I know 2nd and 3rd in mine are a blast

[tjn182]

Fastest I ever trapped was 86mph or so.... but that was non-turbo

[E34nication]

Whats amax=zing is the 93 to 94 1/4 mile trap speeds Ive heard from these cars, I know 2nd and 3rd in mine are a blast

so low 15's in the 1/4?

[323I Junkie]

yep...in fact I have a PDF somewhere.....

I have been amazed at my ability to hurt mustangs...but I have a chip and possibly gears

[Dark Helmet]

Fastest I ever trapped was 86mph or so.... but that was non-turbo


E28 is a totally different beast... teh B34 just DIES up top compared to the B35... especially a d'Sylva chipped B35

[E34nication]

Fastest I ever trapped was 86mph or so.... but that was non-turbo

so what do you trap now?

[bähnstormer]

150mph! TRUBO POWER !

[323I Junkie]

E28 is a totally different beast... teh B34 just DIES up top compared to the B35... especially a d'Sylva chipped B35

So isnt the b34 and b35 completely different bore and stroke?

My L7 says 3.3/3.4 on the intake..I noteice my 86 L7 pulls harder after 100 than the e34 :(..L7 can regulate when necessary

the e34's have the b34 right?

[Dark Helmet]

no, E34s have the B35....

if your L7 is pulling that much harder, you need a valve adjustment and a chip.

cause the L7 weighs almost as much as the E34 IIRC.

Mr Project's B35 pulls hard to redline in 2nd and 3rd, the B34 in my E28 does NOT pull to redline in 3rd, and barely in second.

[Dark Helmet]

and i've got about 600lbs on him.....

[323I Junkie]

maybe I should also mention the L7 has no cats and mandrel bent 3 inch exhasut and High flow airfilter...its been my experience that these older bimmers cats are relaly congested by the time 13 years rolls around

[Dark Helmet]

cat? what's that????? :D:D:D

[Dark Helmet]

do that to the B35 and it will rock your world..... and then send one to badeer......

[323I Junkie]

It is the loudness!

My God its loud! Drives me nuts in an auto 7 series, and thats with a bullet resonator of 14 inches and a magnaflow muffler

I am thinking about a muffler I heard on a civic, its was a magnaflow too, but it had a very, very deep and throaty sound. If I can get the sound, I will definitely do that to the e34.....besides, single pipe 3" mandrel bent is ideal for









turbos
