0 - 60 times, please add yours

[Mitchy]

is this not a forum for discussion mitchy? or should we all sit back and let you tell us everything we would like to know about our cars?

i have NEVER said that i am sure that the lcr will do 60 in second, i only want to know WHY it wont!

the stats i have posted up show that in THEORY it is possible not counting for wind resistance etc.

No but twice now i have provided evidence showing you its not possible and twice you have dismissed it. Where do you think HPA got their figures from? Just plucked them out of fresh air

Your calculations dont prove anything.

Also LCR does not have a 7000rpm rev limiter. It has a 6600 rpm limit. I have a 7000 extended limiter on mine and it will rev to nearly 7500rpm on clocks. This is backed up on vagcom where last recording is around 69XX rpm

Yes it may rev to 6800rpm indicated but indicated is not actual. BOTH speedo and rev counter are as innacurate as each other!

We'll leave it at that mate, next time you ask a question ill do my best not to bother answering you.

using our drag car calculator with 225/45R17 tyre with a 2.11 gear ratio and a 3.88 final drive which is all the info i can find

doubt its 110% accurate as its not used to such small numbers

 

[skahigh]

hahaha, why do you have such a problem with someone asking for evidence? if what you say about the rev limiter is true then thats absolutely fair enough and there is the theoretical proof that i wanted to see all along!

Fl@pper - The LCR doesn't have 225/45R17 tyres. What difference does it make with 225/40/R18?

oh borrox - must have looked up the Cupra

gimme 5 mins to stop

i think the tyre circumference would be the same wouldnt it? or exceptionally close.

No, they would be different. If the width and profile is the same but the wheels are an inch bigger, the overall size would also be bigger.

Normally you would lower the profile when you increase the wheel size, to keep the overall rolling radius the same. But in this case, the wheel increases in size but the width and profile stay the same.

It wont make a big difference, but it's worth checking

 

[skahigh]

does the 40/45 refer to the tyre profile?

 

[RobM]

does the 40/45 refer to the tyre profile?

Yup

225 is the width
40 is the height (profile) expressed as a percentage of the width.

So 225 wide and 40% of 225 as the height.

 

[skahigh]

ah, i didnt realise it was a percentage! all the same 45% on 17 inch wheels comapred to 40% on 18 inch wheels is gonna be pretty similar isnt it?

 

[RobM]

225/40 = 90mm high
225/45 = 101.25 high

If my maths is correct

So not a massive difference, but a difference nonetheless.

 

[skahigh]

aha, so the difference is a little under half an inch! and yes your maths is correct!

 

[Mitchy]

Its only the British market that uses 0-60mph, and tbh im not even sure if the LCR has an official 0-60 time. Rest of world uses 0-100km/h (0-62mph)

The LCR is quoted as 0-62mph 6.9secs officially.

Now to get this figure i think we can all agree 3rd gear was definitely used

If it could be done in 2nd, the 60 time would be low 6secs due to the subtraction of 1 gear change.

 

[skahigh]

also, sorry m.r. davies for the hijack!!!

 

[Bonzy1800]

so ok then, tell me if you had 350bhp and a rev limit of 8k it wouldn't a genuine 60 in second gear i think you'll find it would its not impossible,
BUT as been discussed an LCR will NOT hit 60 in second as j@mes has proved even tho your speedo says otherwise.

i tried doing a 0-60 using my phone started fine but then droped the phone so took about 20 seconds ha ha

 

[CupraUK]

I'm not going argue, but I'm sure I can do 60 in 2nd. My speedo almost hits 70. GPS says 65 on the clock is 60mph.

I respect J@mes' true approach though. Would like to do a test in mine with decent measuring equipment.

I suspect the limiter has been pushed up a tad.

 

[CupraUK]

Out of interest, in order to give the LC and LCR decent 0-60 times, why don't the remappers push the limiter up to ensure that you can do 60 in 2nd?

i think they do my mk3 ibiza rev limit was increased after revo by about 400 - 500 rpm

 

[skahigh]

i dont think people really care on the road do they? if you're have a race do you stop when you reach 60?
