Fastest speed in a coupe

Whats the fastest anyone has been in their coupe ?

Im not interested in where or when as this will just cause trouble, just a figure will do.

GPS figures would be great.

Me:-

140 indicated no GPS.

had it off the clock on my hatch...

so i would sya about 150, as its reads 5mph at 130+ wich was done with my gps.

tbh i dont really do that kind of speed so i dont have a topspeed gps..

was still pulling too, but i bottled it.

mate of mine had his hittin the needle iirc about 157?

I'm prolly way out as it was from clock reading... 145 on flat and it was pulling nicely onward also... didnt realise I was going that quick so I slowed down as soon as I saw it.

Hit the limiter in 5th ONCE with a proper 220 turbo box so 150+
Scared the crap out of me so never again.

Ditto! Maestros are not really too stable above about 130 but it had to be done, just once to see!

Oh, to live near Ehra or Nardo!!

Isn't the 220 turbo box geared for about 170mph?

IIRC andyr has done a real 180mph in his with a modded box. That'll take some beating

171 Andy did iirc.

Interesting

I wondered if the standard box was able to drive the coupe past 150.

Hi,

there's lots of variables, rev limit, overall tyre rolling radius, etc., apart from the gearing. Then the car has to have the power to overcome the drag not only at it's top speed but all the way upto it.

Andy R's coupe at TOTB did a measured 171.8mph from standstill in 1.25 miles.

Cheers

Neil

Thats KPH though

And i've done about 122mph down hill, but i'm limited to 120 by the ecu

Only been to around 130 in the coupe, was amazed how quickly it was still pulling. Had my wee 214Si bubble at 117 once lol, the poor thing didnt know what had hit it.

On one occasion had the needle right round the clock and still accelerating! The only opportunity I ever had to explore the car's top speed. Car had MG ZS 16" Hairpin alloys with Primacy tyres on at the time. Remarkably stable at that speed. Noticeably moreso than 125 indicated with OE 15" alloys and tyres. Very remarkable in fact. Tyres are so important. Like all former Rover TomCat Turbo owners, I miss the car...yer tis:

Apart from ZS alloys~Primacy tyres and rear spoiler removed, car was bog standard. None of my R620ti could approach that exceptional 'one off' top speed run let alone whilst still accelerating. Surface, weather and wind direction all play a part with these one offs..

Multiplying those Kilometre per hour totals by 5/8ths gives fairly accurate Miles Per Hour Figures:

240 x 5/8 = 150.

200 x 5/8 = 125

get's there with worrying ease

Ross9 · Post by **Ross9** » Sat Jul 14, 2007 4:38 pm

off the clock, in no doubt it will hit the limiter in 5th on a flat, so while I've not done it, whatever the real speed is at 6700 in 5th (220 box) on 195/55 15's

0-153.0 in 1.2 miles at TOTB4 on a lesser spec (only ran 13.5 @ 108 that day), speedo's are WAY out at that speed, mine had been sat on the needle for a good while before I got to the line.

Your passenger took pictures of you doing 150?

We know it's you as your alarm LED is blue.

Man I seriously hope that was on the track, it's foolish enough to even do that speed on the road let alone picture it.

For the threads sake we assume all figures are on a track!

We dont need this turning into a debate on safety.

I couldn't make out what the speedo reading was, bit blurred, but 150mph at 5800rpm ? Fairly tall gearing isn't it? Or have I gotten too used to a close ratio Toyota box? Celica does 117mph at 5600rpm in 5th.

216si · Post by **216si** » Sat Jul 14, 2007 10:42 pm

it's a ti box but i am fairly certain the speedo is well out at that speed as said, i know at 110 it's overeading by about 4mph.

oh and that pics a trick

, it was done in my street hehe, car was on axel stands on me drive

Mike · Post by **Mike** » Sun Jul 15, 2007 1:32 am

Once i took my GSI (OK its a hatch) to the limit racing a bike ( on track..), with a 620ti box on i was just blipping the limiter when the outer CV spat the drive shaft out....(snapped destruction type thing!!) Whatever speed that would be??

The outcome was two blown out tyres after spinning twice, not being able to drive the car hard again (me not the car) etc etc, the main thing learnt was...Don't bother, yes they can all do it but do we need to

This is not a "dont drive fast" reply.

Edit: saying all that at least the GSI had air bags and a bit of protection...Metro = pain!!!!!

Can you imagine what would have happened if it'd wobbled off he stand?

Lol, exactly, a bit of wheelspin and you'd stop it - it wouldnt shoot off flat out haha

216si · Post by **216si** » Sun Jul 15, 2007 5:46 pm

no lads it's a turbo, it would snap a drive shaft or spit the diff out

Post by **Punx0r** » Sun Jul 15, 2007 5:55 pm

Regardless of what the engine's doing, you've got energy stored up in the wheels which are going silly speed. I wouldn't bet my life on, but I reckon it'd take off at some speed!

Simply, as typically static friction has a higher coefficient than dynamic, the car will take off slower with the wheels spinning than with a normal good launch. Rev your fwd car to the limiter, even in 2nd, drop the clutch and full throttle, you'll launch at a pathetic pace! No doubt you'd shift forward but not far before you hit the brakes and clutch!

Ever seen a vid of a car jumping off a RR?

Post by **Punx0r** » Sun Jul 15, 2007 11:29 pm

I know it won't be a perfect launch, but there's no way I'd stand in front of it, or do it remotely near other cars/buildings. I'm not saying it can't be done without inviting certain disaster, but if someone might think it's a good idea to try and not realise what could happen
