a very quick x6

[TW]Fox · 30 May 2011 at 13:24

140mph, lol

PMKeates · 30 May 2011 at 13:26

What Golf do you have?

[TW]Fox · 30 May 2011 at 13:27

A wikid tuned one which he did using his secret laptop tuning skills he wont tell us about.

In reality, a slightly shabby 150bhp one

PMKeates · 30 May 2011 at 13:29

Well, I guess it could make it up to a speedo 140 mph, but it would take ages unless it's massively overreading!

Matt82 · 30 May 2011 at 13:34

according to tweb, those x6 do a quarter mile in the 14s which sort of tallies up

the golf has seen 6.2krpm in 5th, with a bit of maths, thats 148

Kenai · 30 May 2011 at 13:35

Having a quick look at 1.8T gear ratios, in 5th gear (assuming 5 speed box), 6500rpm is 135mph, 7000rpm is 146mph.

You'd have to have been really giving it some to get it to 7000rpm in 5th

What ratios are you using? The ones I have would pin 6200rpm at 129mph

[TW]Fox · 30 May 2011 at 13:36

Its yet another silly story from Matt82, imho. You cant really trust anything he says about his cars

Dr House · 30 May 2011 at 13:39

130 in a golf is rather dangerous, I know its still not that safe in a bigger / better car however it would be more stable on the road and could actually stop in less then half a mile should the need arise.

This is why my bother got a beating when I found out that he was doing 125mph in small car I had just got him (Fox you where right) I should have got the 1.4

Matt82 · 30 May 2011 at 13:44

orly?

whatever the case, it was suprising to see something as enormous as an x6 go that quick!

Simon · 30 May 2011 at 14:51

Yeah they can be rapid

Sin_Chase · 30 May 2011 at 15:00

Gear ratios or not, does a 150BHP golf even have enough power to hit 140?

Firestar_3x · 30 May 2011 at 15:06

When my Passat was running 190bhp it had enough power to reach 146 on gps whilst two up with a boot full of gear, so I'd say yes it would provide its geared the same as mine.

Kenai · 30 May 2011 at 15:13

I think the official top speed for the 150bhp models is 134mph

Sin_Chase · 30 May 2011 at 15:15

190 != 150 though. Not sure how weight would affect top speed potential either? Might take longer to accelerate but surely resistance and available power is the only important factors for top speed potential, not weight.

Kenai · 30 May 2011 at 15:16

Weight won't have much bearing on top speed, so much as how long it takes to get there.

Frontal area, drag coefficient, rolling resistance, gearing... they'll have more effect.

Firestar_3x · 30 May 2011 at 15:17

Not sure tbh, I know Matts done some messing with his so it should be more than 150.

exactly, its not normal to see something that is half the size of a BUS staying in exactly the same position on your rear view mirror when youve given it all the beans upto some very stupid speeds.

and then to learn its a diesel, and its only 3.0, i think its amazing

sigma · 30 May 2011 at 15:24

14 second 1/4mile is hardly rapid.

What's wrong with doing 140 in a Golf?

Try doing ~120 in a Citroen Ax!

Kenai · 30 May 2011 at 15:27

theoretical top speed, as far as i can see is given by 53.26 multiplied by the cube root of power over CdA. For the Mk4, CdA is 6.51, so using that with a power figure of 150bhp gives an overall theoretical top speed of 151.56MPH not accounting for gearing or rolling resistance from the tyres

Matt82 · 30 May 2011 at 15:31

mine is definitely not 150bhp, ive seen 148mph according to the rev counter and gearing etc.

one day ill get it dynod, but as much as fox would love to turn this into a golf discussion, the point of this thread is how gobsmacking it is to see an x6 barrelling past at well beyond 130
