0 to 60 times

[Fushion_Julz]

Then you need to:
either look at the 0-62 time for a e34 535i, check to see if the diff ratio and rolling diameter of the tyres is the same and, if not, adjust accordingly. Also take into account how many gear changes are required...

or if the rest of the car is std (15" wheels, 205/55 tyres) then see if the gear ratios of the new box are the same as the old E30 box...If they are, your 0-62 time is going to be much the same as it was when it was an M20, perhaps take 0.5-1 sec for the extra power...assuming that the car can transfer that to forward drive effectively...

Best way is to measure it with a good stopwatch and a GPS unit...

You should go to a rolling road and discover where the peak torque starts to be delivered...
Optimum start is to dump the clutch at 500rpm over peak torque, apply full throttle the instant the clutch bites and to have no wheelspin...change gear at exactly maximum power

wheelspin

A much better test (IMHO) would be a 0-100-0 time...That would tell you not only how good the acceleration is, but how good the brakes are to enable a stop...which, let's face it, is far more important and is probably gonna enable you to be quicker point to point too.

true, but not when im waiting for green at the lights and i want to get ahead of the other guy who wants to always do 10mph less than the national on perfectly fine roads [/quote]

VERY TRUE !

[Fushion_Julz]

yeah, but if the other guy at the lights has a faster car (to 60) or even one nearly as quick and he trys, you won't get in front...
If his car is an auto jag, for example, he will beat you to 30...in fact a decent small diesel will probably beat you to 30 no matter how hard you try.

However, if your 40-60 or 50-70 times are good enough you can overtake in a smaller gap...

Better yet, leave the racing to the track and concentrate on not hitting the pedestrians crossing at the lights.

[fuzzy]

let the pedestrians concentrate on not getting in the road when theres a race on.

[danman2k]

hehe they must be suicidle to walk out when green

Traffic light special hey fuzzy...I'll have a tilt in my sport v your cossie. You'll have to bear with me though while I blow away the cobwebs off my throttle body

Well now is the time to unleash the awsome power of my e30...
1, it is a cabby, so no roof weight +20bhp
2, it has a b25 engine with b20 running gear, so that makes it sport spec +10bhp
3, it has a satin finish, so it has a 'shark ripple effect' as it slips through the air +10bhp
4, the seats are laid flat, so it is lighter +10bhp
5, I'm thinking of fitting an electric fan +5bhp
6, I've got it chipped +25bhp

Now the b25 I fitted sounded good, so it had 180bhp. Than add the above and we have: 260bhp.

Now the other day me and my mate fat Dave sat in while I drove it and he watched the clocks and told me when to switch of the kitchen timer.

After a few 0-62 runs we got it down to 5.6328 seconds.

[johnna]

theres a good 50bhp differance between the two so you cant really compare. wouldnt the carpi have a better power to weight ratio? compared to a 320.

the 320i is 129 bhp when new, probably around 105 now, and the Capri had about 160 which I reckon has worn down to about 140. The Capri is the heavier car though, I think. It feels way heavier. Also the BMW will redline in 5th at 120 mph, and the Capri will do the same at 150 ish. First gear ratio in a 320i is (I think) 3.35, and it's 3.36 in the Capri, so it must be down to differentials..?

Well not only does the capri shell weigh a ton, the cologne is made entirely from pig iron, the rear drive shafts bob up and down inside a rigid scaffolding tube held in place at either side with wibbly-wobbly cart springs.

The take off times of a capri are severly affected by axle tramp and spring wind-up. This is best cured by selling the Capri.

thats not bad when you consider the dead weight of the somewhat hefty geordie driver taking a sizeable chunk out the power to weight ratio
the only part of that ill queary is the 10bhp gained by folding your seats.its been proven that that mod only helps your handling due to the lower centre of gravity rather than any outright power gain.

Actually that isn't exactly true. Standard cabbies had reinforced windscreen pillars in-case the car went over adding extra weight. If you check the factory figures cabbies were always a tad slower than the standard hard tops Yes I know I need to get out more

[Alex]

6, I've got it chipped +25bhp

must be the special ebay resistory chip, guaranteed to give you an extra 463.3bhp

just needs an electric supercharger

a fuel saving device

sport button

and a £20 universal backbox from china and you got yourself 652bhp and 200mpg

and dont forget the new powerbands

Before you do get out (probably by means of distracting the psychiatric nurses) research the term 'satire'.

Well first of all my Caledonian compadre, the not inconsiderable Geordie bulk is crammed into Nomex underpants and is therefore a 'leigchtmetalversion' and secondly the folded seats debated 'unfolded' (can you see what I did there?) to the point that we discovered that flattened out seats did not actually alter the centre of gravity or the kerbweight of the vauxhall in question, which was undoubtedly lightning (not lightening) in its performance. Therefore, we can only conclude that the lowered seats offered less wind resistance than the erect seats did. Naturally all 'true' bhp figures are created whilst in a dynamic wind tunnel rolling road facility. Or as many others call it 'the back lane'.
Finally, this mod was the reasoning behind Fat Dave monitoring the speedo as I lay back as far as I could. We still can't find the split/ fold levers for the rear seats in my cabby, but expect yet another 10bhp when we do.
You see people, in the real racing circles I move in too much is never enough.

[Flozman]

Please excuse the second launch, in the dry its fair game getting enough wheelspin to get away but its been peeing it down and i bottled it as the back was overtaking me again.

[Flozman]

Did i mention i was holding the phone while countersteering?

Oh I'm not going to fall into that trap. I want my Cabby to be nicely balanced.

So as well as the universal back box, I'll fit a universal front box...

[zimmer-320i]

lol such a waste of ebay fees, good tho and a very good point dont forget the fuel adative alex i mean there proven to give a 20bhp gain

[Nay]

haha, where i'm from (Jersey, channel islands) doing 0-60 is illegal! I could time a 0-40mph tho. lol!



lucky bastards...

[zimmer-320i]

is it really lol ^^ bad lick well do a 0-59 mph time lol

[Nay]

Lol, either way i'd still do 60 although our roads only allow 40 mph, 30 for most. Kinda sucks but if no police around everyone just goes 50. Amazong roads tho, loadsa country lanes, hills, coast roads big corners etc. Really fun place to drive as everyone knows pretty much all main roads so its not so bad. Makes visiting the mainland fun as we all love motorways.......
