60-100mph times

Has anyone got any 60-100 times for their Coupes? Any stage of tune will do. I'm after 60-100 from a rolling start as I think this is where true power is measured. I've never been one for drag racing or 1/4 mile standing starts kills clutches and there aren't to many places to put this into practice these days. Video of one of my motors with a 19t turbo flitted below.

B204 19t 60-100: https://youtu.be/cNsRHBu-g0c

That was with a base map and it ended up with a recorded time of 5.4 seconds iirc.

Some folks have done it in 4 seconds with gt3071/76 turbos. So what times we got????

Estimated figure from Trappy's stats for my car is 3.86 seconds (and 8.23 for 60-130)

However, his estimated stats are fairly accurate for my quarter mile figures (my best is 12.39 against Trappy's calculation of 12.8), so I'm inclined to believe they're in the right ball-park

That's immense. If that 60-100 figure is based on a 0-100 run then youll be even quicker just dropping a cog and mashing the throttle. Thanks Nigel. 60-100 times should be in the coupés favor because of the gearing so I reckon we should see some great times.

My figure of 3.86 is simply my 0-100 of 9.06 less my 0-60 of 5.2

My calculator has come a long way since then In fact I’ve been working on a data sheet that can be posted up as an image. Here’s the print of two data sets using the FC dyno print from your old spec (which I believe is the set up that ran the 12.39s). The only difference in input (left hand column) is the road vs drag strip surface the car is launched on.

OK, I've spent 30 minutes scratching at this. Why on earth would most of the stats in the above links be blacked out between Photobucket and the forum? They're just images taken from a spreadsheet!?

Gotta be the imgpop implementation.

I've never recorded any times but I know it's quick and the coupe will do a ton in 3rd but I find 4th is quick enough and saves a bit of wear and tear on the motor

that it is , have removed the imgpop on trappy's post and it now show's all the info .

I'm on a track day soon so will try to time some speeds and post it up along with my spec.

Thanks for that, Nismo

the 12.4 drag strip quarter mile time is amazingly accurate, but a few comments:-

1) the 457bhp spec was in my old Sprinty when I did my 12.39, but I was about 50-75kg stripped out

2) I'm now running more power, by about 30bhp (regardless of whether I was actually running 457 back then, I'm definitely running more than I was)

3) Why am I changing up at 7k rpm? - Rev limit is 7400 - 7500, so when really going for it, I run it to the limiter in order to keep the revs up post gearchange

4) Top speed appears to be down compared with earlier calcs (not that I ever expect to get anywhere near them, although I really fancy a run at a VMax event, just to see what it'll do)

RAF Marham track day has an excellent Vmax strip. Its a good cheap, safe weekend. Worst you can do is get a cone wedged in your grill or arch.

I have only 80-120kmph figure on 4th gear - 7s which is quite good for NA engine with powerband 5500-8000rpm

here is comparison with civic vti at 1/4track, and further 1km track...
video: https://www.youtube.com/watch?v=rbovrUWn8ME

times were:
1/4.. 14.4s (153kmph)
1km.. 26s (200kmph)

But now, with new exhaust and ecu, and few other bits( CrMo flywheel, 230mm clutch, shorter final drive) are the values lower... 1/4 mile is now under 14s region

Nigel I take it you get mega wheel spin if you try and achieve a figure less than 5.2 to 60 due to nearly 500 bhp??
I've definitely done 60 quicker than 5.2 and I have/had around 125 less horses than you??
Think my 60-100 was around 5.5 secs!

Nick

OK, I’ll make the 75kgs amendment and see what happens…



I used the 457bhp dyno as I knew that’s what you were running when you did your best ¼.



Hmmm… I seem to recall your old dyno plot stopping at 7,000rpm so figured it was limited there. What was the limit on the old spec as I thought you had it extended when the new turbo went on?



That would be because of the rpm limit. The last times I gave you were for the 488bhp with 7,400rpm limit.

Confirm the old rpm limit and I’ll run it again

You're right - my previous 457bhp graphs stopped at 7,000rpm, as the power was tailing off after about 6500



Limit was increased to 7,300/7,400 when I had the bigger turbo and bigger injectors

Here are the numbers for your drag run at 75kgs lighter with 457bhp.

It would appear that any gain from the extra bhp at the top is negated somewhat by the additional poke your old spec had when first changing up through the gears.

I agree that the old car was quicker off the mark and through the mid-range

I'll dig out the timing slip for info - one that springs to mind is a 2.01 60-foot time

EDIT - closer to 2.02 than 2.01, but still decent....

Right then, clearly my calculator is MILES out! The launch is far too slow and the terminals are too high. I need to do some work on it!

What tyres were you using for that run?

I wouldn't say miles out - the ET is very close, but the way it got there needs a bit of fine tuning. My normal 60 foot time was in the region of 2.2 and my usual terminal speed was 116 - 120 (in the 457bhp car)

To be fair, that was an unusually epic launch - 6,000rpm, side-step the clutch and it just gripped (and the gearbox didn't explode, like it did the next time I tried the same method....)

Tyres for the 12.39 run were Yokohama AO48 trackday tyres

Not sure if this helps, but here's mine, a rolling start from 30mph onwards - https://www.youtube.com/watch?v=Jsr_DuMEX0g

PS - Trappy, if it helps, I have quite a few timing slips from Santa Pod - happy to scan them and email them over if it helps to refine your calcs

Nice one. Still determined to get a time for mine before live map, fuel pump wiring mod and FMIC and after.

Will up load the video later but done a few 60-100 mph pulls on a private test track this morning a recorded a very repeatable time of 5.6 seconds which I'm very pleased with. I can see why these cars are so quick around these speeds. My car is very quick from 60-80 but then struggles a bit to get to the ton. Having said that its only a bit slower than my earlier video of my old Saab 9-3 with a 19t turbo. This car keeps on giving

Here's the video. Timed on movie maker and with a good old fashioned stop watch to 5.5/5.6 seconds.

Anyone got any standard Coupé times?

Can I just ask, what is the interest in 60-100mph? I get 0-60, I get 0-150, I get 0-150-0 but not 60-100, its completely irrelevant Phil? That's why there's no data on it,

When was the last time after telling people you have a 290hp car, someone said, "Oh, what's the 60-100 time?"

;);)

Thought I covered this in the OP.

Its not irrelevant to me. The petrol heads I associate with are more interested in 60-100 times too.

zero to anything is simply a measure of traction and how brutal you're prepared to be

A rolling start is simply a measure of power (and the spread of it), so its a far more reliable indicator of how quick the car is - quite simply, it removes the driver from the equation (other than perhaps a gearchange time if you choose to start in 2nd gear)

That's some very good real world performance. Even if we round it up to 6 seconds to account for speedo inaccuracy, it puts the Coupe in very good company

Cheers

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.

Turbo:
BHP @ 2000 rpm:

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....)
