for anyone interested the link below will work out speed per gear using ratios AND tyre sizes

well noted on the tyre sizes

 

[Mitchy]

When manufacturers quote 0-60mph they dont do it from the speedo.

0-60mph on speedo is really a 0-56mph test.

Mitchy, i don't think he's trying to argue with you he just started a thread to see what people have tried and got as a result. He even said himself it would be inacurate so why not just leave it?

 

[Mitchy]

Yep i have

0-60 in 5.5 with masses of wheelspin for me.

LCR 350-360bhp

Yeah nitrous is a pain in the ass in 1st and 2nd. 400lbft through the fronts is all good fun though

 

[W88DSY]

My LC does 60 in 2nd? when i read this i went and checked again, it really does!! will try and get a clip, and post a rough 0-60.

 

[chriswilks]

my lc does too, hits at least 64 on the speedo in 2nd

 

[richybigman]

LC's are 5 speed boxes though aren't they? That why the LCR can't do 60mph in second because of the 6 speed box

 

[W88DSY]

nah! they are also 6 speed

 

[richybigman]

Oh well that's my theory out the window, i'm sure someone will have a decent answer for you

 

[skahigh]

mitchy, your link also states that the top speed in 6th is 168....wanna explain to me why the lcr doesnt do that?

 

[skahigh]

ok, so im being a bit flippant here but i would like to know the mechanical reasoning behind it rather than just figures stated by a tuning company trying to seel an upgrade product.

Who has ever said the 6sp box cant do an indicated 60mph in 2nd?

Yes it will, but it only equates to 56mph.

manufacturers do not do a 0-60 off the clocks FFS

Mechanical reason for what? Gear ratios? Dont get your point?

Most 6sp boxxed cars cant do 60 in 2nd. I had a CTR beforehand and that was exactly the same!

mitchy, your link also states that the top speed in 6th is 168....wanna explain to me why the lcr doesnt do that?

Not enough power, box shaped, aerodynamic drag for 1.

Dont take the brains of einstein!

222bhp is not enough to overcome aerodynamic drag for 168mph.

You need a good 350bhp+ for that.

Here, to bury this once and for all and to stop skahigh arguing black is white.

Here is proof....

http://www.seatcupra.net/forums/showthread.php?t=100070

J@mes has increased limiter and 280bhp. J@mes does not have 222bhp and standard set limiter.

And yet still his limiter kicking in at 59mph.

THANKYOU!!!!!

Professional timing equipment used.

ok, ive done some research and heres what i've found:

lcr diff ratio = 3.88:1
lcr 2nd gear ratio = 2.11:1

(http://www.supercarsite.net/seat/leon-cupra-r/2001)

standard tyre circumference = 2001.82mm or 78.81 inches (http://www.alloywheels.com/tyrecalc.asp)

inches per engine revolution = tyre circumference / (diff ratio X gear ratio)
inches per engine revolution = 78.81 / (3.88 X 2.11)
inches per engine revolution = 9.627

lets say 7000rpm...

7000 x 9.627 = 67386.85 inches per minute

multiply by 60 = 4043118.19 inches per hour

divide by inches per mile (63360) = 63.81 miles per hour!

Not enough power, box shaped, aerodynamic drag for 1.

.

lost 400bhp on last year (on a borrowed engine after major blowup)

as boxy as a box stuck to box car

drags so much paint comes off

but still does over 160 in 2nd

just thought i'd lighten the mood a bit ill get me coat

 

[skahigh]

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.

 

[RobM]

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

I can answer this... it wont because the gearing will not allow a true speed of 60mph. It falls just short. Even if you over-rev and go beyond the point where your car stops making power, the speed wont hit 60.

Increasing power doesn't change the gearing either, it just helps you get to the same point faster
