What sort of performance are any of you guys achieveing with standard and tuned 20VT's? The original Autocar test reckoned 0-60 in 6.0 and 0-100 in 14 secs. However, I can't say I've been in a std 20VT (including my own) that feels anywhere near this quick. I guess the tuned boys will be closer or better than this, but by how much? Share your experiences here.

Standard varies on the tyres, launch, surface, but You can tease a 6-second dash to 60 usually, and I don't know about the 0-100 but I was doing the quarter in about 15 seconds normally, unless it was an exceptionally fast run and it dipped into the high 14's.
Tuned? Well take your pic. My best was 5.72 secs to 60 and a 14 sec dead 1/4 with breathing mods and a G-Tech 1. We've had sub 12-sec 1/4's before now (flea and Mavric)
If you want a pretty accurate measurement of your car's performance, buy a G-Tech performance Pro meter cheap off ebay and find a nice quiet road. They are accurate to within 1% providing the road is flat. You'll notice how easy it is to fluff the launch causing a 7 second-plus launch and crappy quarter. It really is all about the launch if you want to get any decent results and in the rain? laughable!

Interesting thread!

I'm actually doing 80-200 km/h (50-125 MPH?) in 16 seconds. I made 19.5 or 20 seconds when my car was full stock.

I have a 20VT with decat + free flow catback and my own eprom (250 HP?)

I'm going forged/balanced soon + FMIC + light Headwork + 3" DP + GT3071R-WG + 440cc + lots of other parts and i hope for 10 seconds.

9.9 seconds will be my dream

0-60 is so so difficult to get right in the coupe...
I'm guessing i'm between 5 - 5.5 secs to 60!!
60 - 100 is a much better measurement for coupe performance... Filmed mine recently then timed it ( allowing for my peedo to be approx 10% out i timed from 66 - 110.... which i did in 5.8 secs!!

Which surprised me, currently running 306 bhp tho!

I'm doing 0-90 in 8, 0-100 in just under 10, 0-115 in just over 12, 0-150 in around 25

Autocar got a 0100mph of 14.5s in the original 1996 doad test of the 20vT but then recorded only a 15s in the 0-100-0mph article a few years later. Just a little detail but still important.

Flea did a redline day a few years back, the results of which I've uploaded here

He estimates that the car was making 390bhp at the time.

what would you say a 260bhp coop would make trappy and a 300bhp coop?
i remeber you doing a chart a little while ago but i can't find it

0-60 times really vary. It all about the launch, tyres, tyre pressure and weight your carring. You could acheive anything from 5.5 to 6.2 secounds.

Here are the numbers it brings back peanuthead



It is very important to remember the difference in performance that even a few minor mods can make. The boost limit overide will HUGELY improve 2nd gear performance as it removes the boost limit, giving up to 60ft/lbs of extra torque in the lower gears. I reckon it would give knock 3 tenths off the standard cars 0-60mph.

so a 300bhp coop is about the same as a e36m3 evo if it hits its actully 321 power output?
i guess more likely a m3 e46 rival then?
getting 0-60 yimes like that would be really good.
60-120 mph i bet the coop is in its eliment?

The BMW has it's power within a really narrow band of revs. Not so the 20VT!

There is NOT a boost limit in 1st and 2nd gear in a 20vt.

No it does not - it just has a normal linear powerband rather than a turbo.

As you start going over 300bhp in a coupe the powerband is going to suffer - a bigger turbo will not spool at 2,500 like the standard car. Below 4,000 rpm an E46 M3 would have a significant advantage.

But there is on the 16vt???
Probably a good thing to be honest as if (when) the wheels start spinning in 2nd i'll prob only see at most 1 bar untill i'mm into 3rd!!
Is that chart for just 20vt coops as my 60-100 is alot quicker than 6.7 sec!! (i'm running 306 bhp)

Nick

Sure, but there is a boost RISE limiter in all gears but it only works in 1st and 2nd as these are the only gears that a standard car can trigger it in. It effectivley limits torque available in these gears.

so, if looking at a boost gauge, what difference can you see in 1st and 2nd gear between a standard and chipped coupe?
will a chipped coupe boost higher in 1st and 2nd?
in my coupe, 2nd gear boosts to 17psi quite easily and really pulls,1st gear seems to be a bit less unless i realy put my foot down.

Yes

2100rpm 77hp /246nm
3300rpm 177hp/360nm ( seems high to me )
4000rpm 205hp/350nm

those are from e46 M3

my 0-60 is around 4 sec, hope to get it a little better when i get it finetune.

Nope - the ecu cuts the boost on the standard chip if the revs rise too quickly, i.e wheelspin. No wheelspin then no boost cut.

i have a big turbo on my car and i love comparing e46 m3's with my car and to be honest i destroy them from start to finish and yes i mean from stand still and from rolling,just becoming a pointless comparison,wouldnt mind one as a every day driver though

in a Coupe? That's a bit optimistic

Its not a coupe anymore, its 4x4

Do you have any 0-60 figures for yours Nigel?
Last year I recorded 5.1 to 62mph, and now its much better with launch control and traction control, so I am guessing my 0-60 would be around 4.9 now Will do some measurements soon...

I don't have any 0-60 figures for mine, but I guess it would be fairly close to five seconds

Kenneth - apologies - didn't realise you were 4WD - in that case, 4 seconds is quite possible with a brutal launch

I dont care what turbo or spec of coupe you are in - you will not beat one off the line unless you get a PERFECT launch, and the M3 utterly fluffs it - or can't be ar*ed.

When rolling you will also not 'destroy' one in a straight line until you have a 400bhp+ coupe.

i duno if im just a s**t drive but i recon my 0-60 time is worse than standered i rele wanna go in someone elses coupe similar to mine to compare. i just get pure wheel spin in 1st no matter how much i ballence the clutch n fether the throttle. although my iphone time me a 5.2 sec 0-60 time but fccuk know how accurate that is.

It wont be accurate. I really can't see why anyone is bothered about the 0-60 time of a performance car - it really depends on the drivetrain and weight of the car and the launch. The claimed figures can't be replicated without a fair bit of luck - and even then it a very poor reflection on how quick a car is in the real world.

The statistic is for meaningless pub arguements:

'my car does 0-60 0.2 of a second faster than yours according to the figures in the back of evo, and they gave it a good writeup, which is the only reason I bought one.....'

Stick drag tyres on a 20vt (not AWD converted one) with 400bhp+ and you'll get a 5 second 0-60 or a bit less. Add another 200bhp and I doubt it will change much.

ok then suba i cant destroy m3's with my coupe from standing or from rolling i must be lying

BMW M3 2002 :
343hp/365nm

0-100kmh 5,2 sec
0-160kmh 11,6 sec
0-200kmh 18,6 sec

so 100-200kmh is 13,4 sec .
well I have to say, that is easy to beat at least..
