Good grief.... I didn't realise just how fast my cheap little Fiat is compared with some properly exotic stuff - one of my current favourites is the R8 V10 Plus, but its about a second slower from 60-100

Seems I'm going to have to save the pennies for a bit longer to go noticeably faster....

I did the same test in mine yesterday just to see how it compares to yours. Funnily enough, it was about the same time overall but mine struggles at the lower speeds. 90-100mph is when it's fully into its stride!

Just as a matter of interest how is this test measured?
Accelerate from below 60 anyway you like upto 100 then take your times from 60-100
Or reach 60 hold it steady then plant your foot as the clock starts?

I'm sure they used to do this test like the latter version in 4th gear?

Just be interesting to know!

Cheers

Pretty much the way you've said. Rolling start from whichever gear is best suited, just make sure your on full boost passing through 60. Some folk do it all in 3rd, some 3rd and 4th and some 4th. All depends on your gearing and turbo set up.

What Phil said ^^

If you hold at 60 then plant it, there will be a degree of lag while the turbo spools up

The most accurate way is to floor it at (say) 50, then start the stopwatch as it touches 60

Please note that this thread is probably breaking forum rules, as we appear to be openly discussing the setting of times involving three-figure speeds on public roads - probably not a wise idea

To save our licenses, I would suggest that Ryan (Trappy) might be persuaded to generate some Coupe stats for various configurations - his figures are remarkably accurate for my own car, so I can't see they'd be any less accurate for yours

Trappy! your welcome to use my stats if you like just let me know! Would be fascinating to see what they are!
I will send my details across if your happy to oblige!
Cheers Rich

Same here Trappy. My figures are on this thread I think. It would be interesting to see what your simulated figures would be 60-100 compared to my real world figures.

Great too see high powered Coupes mixing it up with some expensive exotica.

Thanks for the ‘volunteer’, Nigel!
I think we need to be clear that the run as discussed so far is for a 60-100 in 3rd gear. For the 20vT this is a good measure of overall performance because it covers a very broad part of the rpm range.

Any quoted times for other cars covering this increment will be ‘through-the-gears’. If we wanted to extract the best 60-100 time, we’d start in second gear where even standard cars can manage 70mph. Coupés with extended limiters will often manage 75mph+.

With the right data, I expect to be able to calculate a ‘through the gears’ run from 60-100mph and it will not factor in spool time. Consider it a 50-100mph starting the clock at 60mph. I need a fair amount of data though, as below. If you want to see the number, then please fill it out and send it over.

Assumptions

Weight
Coupé 20vT weighs 1400kgs and the driver weighs 80kgs

Gear change & spool times
It’s become apparent recently that these are a lot bigger than I initially suspected. For a manual car this includes time to change gear and time for the turbo to spool again. It could be even more than the times below.
T28s, GT28Rs, GTRSRs take 0.5 seconds
GT2871rs, GT30s etc. take 0.65

Dyno results
I have to assume that these are 100% accurate and so could give skewed results if the data set you have massively under or over read the truth.

No problem - I have every confidence in you

At the risk of being howled down here: isn't a 60-100 timed from cruising at 60 in the gear of your choice a more useful real-world measurement? After all, if you're overtaking someone you're more likely to have been following him for some little time and so starting from an off-boost status.

No - on three counts

1) that would be a measure of how small your turbo is (or even whether you have one at all... ) In my car, if I floored it in 5th or 6th at 60mph, very little would happen, for a very long time. I would always drop it to 3rd or maybe even 2nd, ready for the overtake opportunity

2) we're trying to measure outright performance here, not "driveability"

3) Its far more fun to drop a cog (or two or three) and then do a full-bore fly-past

Remember the Top Gear EVO400 v Fiat Stilo test? - it "proved" that a 1.6 Stilo estate was faster than an EVO400 over 1.7 miles, if the starting point was a 30mph rolling start in top gear (ie it proved absolutely nothing at all....)
