 You:…… But I am confused about the gear ratios. There are only three that exist? Short is 55 mph in 1st gear, medium is 62 mph in 1st gear, and long is 68 mph in 1 st gear, right? But with some DIablo's capable of higher rpm, this may change?
Me:……….Yes, 3 gears ratio!!!!!! Yes change compare a 7300rpm limit to 7500 rpm limit!!!!

You:…… But if the Diablo 6.0 can do 62 mph @7500 rpm, then this means it has shorter gears than the original DIablo VT that can do 62 mph @ 7000 rpm? With the same gear ratio as the old VT, can it do higher than 62 mph?
Me:…….Probabilly is an error, not 7000rpm but 7500rpm is the same gears ratio!!!!!

You:…… The GT and SV have the same gear ratio's, but the GT can go to higher rpm; does this mean the GT has a higher top speed?
Me:…….Yes, in all the gears!!not only in top speed!!!!!!!!

Many magazine are not exact and not correct for the RPM numbers, because they take the rpm whit eyes on the “RPM instrument” ant not with test instruments like correvit!!!!! But all the Diablos with hp max at 7000 or 7100 can arrive a 7300 at redline or 7500 at electronic limit and the other Diablos that has max HP at 7300 (also VT6.0 if 7100) can arrive at 7500rpm or also 7700 at electronic limit, and sometimes is difficult to understand the length of gears!!!
example:
in 1st a Jota can arrive a 101km/h at 7500, like GT, VT6.0 (with medium ratio) and a VT’93 or a VT’99 arrive at 98/99km/h at 7300, but sometimes if you “push hard” you can arrive at 7700 in 1st case or 7500 at electrinic limit in the 2nd case, but sometimes !!!!
In 5° gear at top speed the Diablo that has 492hp or “VT 530hp” arrive at 7000rpm and 7100rpm and not more, but the SE, SEJota, VT6.0, and GT can arrive also at 7500 in V!!! ….but I don,t know why over max power!!!probabilly for the power engine characteristic compare to aerodynamic Cx!!!!
For me is difficult that a Diablo can did over 340kmh because it has not more rpm in 5°gear, if you have a GT whit long ratio, and you are in 5°gear at 338km/h at 7500rpm, you have not more rpm available, you can not take the 200prm more, and you can not arrive at 350 or 360kmh……..
With short ratio is not the same thing, GT did 320km/h at 7700, a SV can did not over 7500 and did 310km/h……..for the short ratio compare to aerodynamic and power characteristic ……with long ratio GT can did 338km/h at 7500……and a SV’99 probabilly not over 7100 or 7300….but is strange that a VT99 arrive at 7100* at 331,9km/h and a SV probabilly 329kmh at 7300,* but sometimes top speed rpm tested are not correct…and is 7300rpm in truth……..
>>> In any case is simple understand if the gears ratio is: short, medium, or long…..this is important
The wing can vary the top speed in not over 3km/h and not 8mph!!!!!!!!!!!!!!

For the weight, I have this:

Diablo 2wd: 1682kg (with 2/3 fuel, driver, correvit)
Diablo VT: 1720kg (with 2/3 fuel, driver, correvit)
VT6.0: 1730kg
Jota: 1680kg (with 2/3 fuel, driver, correvit)
GT: 1720kg (with 2/3 fuel, driver, correvit); 1620kg (on road)
Murcielago: 1840kg (with fuel, driver, correvit)

*consider that a 2/3 of fuel weigh approximately 50kg(1 liter =0,735g) and 70kg for driver!!!

Is strange, but is correct!!!!Lamborghini declare various weight for Diablo, but are similar in all models different in not over 40/50kg……GT have the interior video, posterior camera for parking, and other little thing ……Jota has the Jota engine parts, big brake,……… …...and than all the Diablos are the same car with the same chassis, and the body if in alluminuium or in other material with other lighter part can vary little the weight…..I don,t know why, in this tests, I have this weight!!!!!!! Probabilly Lamborghini say not true things…….
Also F50 seems that weight less than F40 because has all carbon fiber chassis and other lighter part, but F50 weigh over 1250/1260kg on road and F40 weigh 1160/1180kg on road with an older mixed chassis!!!!!
Probabilly GT and SE or SEJota has other heavier parts, ………brake, rinforce chassis, and for GT other aerodimanic interior parts………..I don’t know why this weigts, but are correct!!!!!!! Are variable the 2/3 of fuel and the driver weight but for little kgs but this wights are correct!!!!!!!!
I hope to be comprensible, sorry my bad English!!!!

VT6.0 has the same gearbox and gears ratio of GT, is the same car…….but VT6.0 is the standard version whit 4wd and the GT is a 2wd road racing version!
SV and “530hp VT versions ” has available the rpm in 7100 and probabilly (with standard gears ratio) can did a top speed little little faster than old 2wd and VT!!but the difference is little!!
I have a test that Diablo VT’99 did 331,9kmh at 7100rpm with the long gears ratio, the same of VT6.0 (335km/h) and GT (338km/h)!!!!!and probabilly with standard medium ratio did 327/328…….also VT 530hp and SV 530hp has various gears ratio……….
I see strange the 21,4s in 0-1000m for GT with “long ratio”, because if you look, with the same gears ratio, Diablo 2wd did 0-1km in 22,4s with 492hp and 1682kg (with 2/3 fuel and driver); SE30 Jota did 21,2s with 600hp and 1680kg (with 2/3 fuel and driver)!!!!
I wont say that: with the same weight, same gears, and 108hp more, we obtain a time of 1,2s less, and GT whit this gears ratio (medium: 330km/h) and 1720kg ( with fuel and driver) and 83hp more only 0,9s less than 22,4s and can did approximately a best time of 21,4/21,5s but not less, and now, whit the 338km/h ratio it did not arrive in less of 21,6/21,7s!!! is a proportion!!!!!
I wont say that probabilly with the same gears ratio, the Jota is little faster in acceleration than GT!!!

Jota = 0-1000m: 21,2s
GT (330kmh medium ratio)= 0-1000m: not less than 21,4s

And I wont to say that probabilly a SV’99 with short ratio, is little faster than GT with long ratio (338)!!!

SV’99 (315/320kmh short gears ratio) = 0-400m: 12,0s 0-1000m: 21,4/21,5s
GT (338kmh long gears ratio) = 0-400m: 12,1s 0-1000m: 21,6/21,7s

Yes, because only 45hp of difference, and similar weight, but very different gears ratio, can did this……….and if you compare theoretically a Jota with the same short ratio of GT and SV can did 0-1000m 20,8s and a 0-200 in 11,5s!!!!
If you wont, you can buy in a Jota or in other Diablo model the gears ratio of VT6.0 and GT, because is the same car, and is possible change the ratio.
My friend has a Diablo 2wd’92 and last year he broked the gearbox of his Diablo, ……after,….. he buy the short ratio of GT and now his Diablo is faster………..and probabilly like a Diablo ’99!!!!!!
Gears ratio are important!!!!!!!!

 I have another test of Diablo GT, but I do not know what is the gears ratio……??!!??

Top speed 330kmh
0-100: 4,4s
0-160: 8,7s
0-200: 12,8s

I think is the medium ratio, because did 330km/h and did 0-200 in 12,8s vs a 12,3s of Jota with the same medium ratio and there is a little difference…….probabilly with long ratio Diablo GT did 0-200 in over 13s!!!!!!!but is strange this test for me………..I don’t know……….is strange, because I don’t know if is medium or long!!!!!!!!! I creed is medium, but I consider strange a over 13s in 0-200 for long ratio!!!!!!

 and why F50 did 0-100m in 21,1s vs 21,0s of Diablo GT???
because F50 has "big downforce" (310kg @ 300kmh) and has less torque of Diablo GT:
F50: 471nm @ 6500rpm
GT: 630nm @ 5500rpm

 So, in any case, and any Supercars, is important weight, max power, but is important also the available quantity of power at the medium rpm** (for ex: after a change of gear and not only at max rpm) , and all in compare also whit gears ratio and the length of gears, also compare with aerodynamic Cx and Cz, …………for understand performances of a car!!!!!!

**for ex: if two cars has the same hp, same kg, same gears but differents power at the medium rpm, they can not did the same times!!!!!

- car n°1: 500hp max @ 7000, 1600kg , same gears, 400hp @ 5000
- car n°2: 500hp max @ 7000, 1600kg, same gears, but 350hp @ 5000
- car n°3: 450hp max @ 7000, and 1200kg, same gears, and 320hp @ 5000


The 2nd car has less power at medium rpm and less fast after a change of gear to return at 7000 why less power at medium rpm to push the car!!

But the 3rd car is faster than the other in any case, medium rpm and high rpm, why weigh less and has a better quantity of power at any RPM compare to weight, it has less max power and less medium power, but is faster for the less weight!!!

This is a good example for understand!!!!!!!!!!!!
I hope to be comprensible!!!!!!

 Is strange for me a VT6.0 at 360km/h (probabilly in speedometer) because for example GT did 338km/h at 7500rpm with long ratio, and probabilly are availiable other 200rpm more, and a VT6.0 probabilly did 335km/h at 7400/7450rpm for less hp at less rpm, but for did exactly 360km/h a VT6.0 did arrive at 8000rpm and not availiable rpm!!!!!!I creed that Diablo did not arrive at 360, can not!!!
Top rpm are 7700 but with short ratio, “teorically” with long ratio at 7700 did max 347km/h but is impossible to arrive for compare aerodynamic vs power availiable!!!!!!

 Thank you!!! You have been very helpful!

Only two more questions and then I understand everything!

"Yes, in all the gears!!not only in top speed!!!!!!!!" (Saying the Diablo GT has a higher rpm and top speed than the SV)

But can not the '99 models with the same gear ratios also do 7500 rpm in some gears like 1st, but only not 5th gear? So they would actually be equal in some gears, but only not top speed. So the '98 and '99 VT is availiable with the short ratio of the GT? But would have a top speed of only 310-315 kmh because they can not go to the high rpm of GT? I think I understand now.

And what about the weight of the regular SE30? It is lighter than the 2WD and Jota? I read that the power to weight ratio of the SE30 was very good, but if it weighs the same as the 2WD and only has 30 hp more, that would not make it a lot faster! It needs to be much lighter than the other versions. The SE30 has approx the same power as '99 SV, but has longer gear ratio like 2WD; it needs to be much lighter in order to be so close in performance (1/4 mile: 12.0 vs. 12.1 seconds, 0-1000 m 21.3/4 vs. 21.5/6 seconds). So the regular SE30 must be lighter than the 2WD, right?

For the top speed of the long ratio Diablo 6.0, it was done by Top Gear. I do not know the background information on this test, but it was supposed to be reliable. But because Nardo is curved, each top speed test at Nardo they allow for 3% increase in maximum recorded speed. So for instance we see many times:

Mclaren F1 231 mph at Nardo
but actual recorded speed at Nardo approx 221 mph

Buggatti EB110 SS 217 mph at Nardo
but actual recorded speed at Nardo approx 213 mph

So in the case of the Diablo 6.0 long ratio

Diablo 6.0 223 mph at Nardo
but actual recorded speed at Nardo approx 215 mph


All top speed runs at Nardo are allowed to add 3% increase. I think it is not accurate to do that, but oh well. Thank you for all the information again.

 the jota performance is widely disputed but im pretty sure that these are the right stats (i got them from the best websites i could find)

max speed-339.2 kph
0-100 kph-3.7 seconds in first geat (pretty good huh?)
gearbox- it is 5 gears (the so-called 6th gear war actualy reverse!)
max power-595 bhp@7300 rpm although in the marketplace it was reputed to have 600 bhp
on a final note the jota was produced in 1995 not 1996
respect
diablo se30 jota is da shit

OK, you have understand!!!!!!
For the standard SE30 probably weight 10/20kg less than Jota!! Probabilly 1660kg at full weight!! And with 525hp and the same 2wd gears ratio did 400m in12,1s and 1000m in 21,5/6s!!!!
The SV’99 weigh probably 1680/1700kg and has 530hp but with short ratio is little faster than SE30 and did 400m in 12s and 1000m in 21,3/4s!!!!! but SE30 did approximately 330km/h (or probably 333 like Jota at 7500, if Jota did 339,2 at 7700) and SV did +310km/h at 7500!!
This are the correct differences!!!!!Do you have understand???
Is all OK???

 Jackamo, read whot I say here for you, is interesting:
http://www.supercars.net/cMsg?viewThread=true&year=1999&make=Lamborghini&model=Diablo%20GT&fn=56
for take an example of "avaible medium power", Murcièlago did 20,9s in 0-1000m, but if "teorically" 2wd probably did not under 21,3/4s like an SV with short ratio!! Murcièlago has a big weight, app. 1840kg at full, but it has a "good available medium power", this 6.2 litre has 500hp at 5400rpm and a max 580hp at 7500rpm!! for this Murcièlago has also good times like an SV whit short ratio, because it has long ratio (1a: 101 2a: 146 3a: 199 .....) but a optimal power available at "medium rpm"!!!!for example better than also Diablo GT why 480/490hp at the same 5400rpm, but lighter(1720kg) and available with short ratio!!!!
So Murcielago has 580hp on 1840kg, and is available 500hp at 5400!!and this is good, but not sufficient for be super fast like a Jota or a GT!!1840kg is a big weight!!

 Thank you for the test. But I think the Jota can be a little faster, because in comparsion to the Ferrari F50 (1 km standing in 21.3 seconds), the Jota is more than 0.1 seconds faster. At least 0.2 seconds faster I think.

Quattroroute is the best magazine for test results in comparison to other cars, and they are very consistent. But when comparing cars tested on two different occasions, you may add or subtract 0.1 seconds to 1 km standing.

 remenber!!!in this test SE Jota has long-gearbox ratio beacause did 333km/h in V!!!!!and Diablo GT 0-1000m 21,0s why short-ratio!!!!!

 I think the gear ratio's for the Jota are the same as the VT and 2WD right? The gear ratio is not that big difference in performance. Only extra long gear ratio optional for the DIablo 6.0 makes a big difference in acceleration and top speed, but the Jota does not have the extra long ratio; only has normal gear ratios like Diablo VT and 2WD). SO in comparison to the Diablo GT, the Jota has more power and is lighter, and also is the only Diablo to have Variable Air Intake system. I think it can match the GT.

 Jackamo, slight error on your part. Gear ratios have a major part to play in a car's performance. Long gear mean better top speed but accelaration (especially at low rpms) is compromised. A low speed ration is basically the opposite. The way an engine's power is used depends largely on the gear ratios
Can't think of a witty line to put here either.

 Yes, but the difference between gear ratios for the Diablo GT and VT are not very big:

VT top speed: 202 mph with wing, 206 mph + without wing
GT top speed: 199 mph with wing (not availiable without wing)

An overal difference of 3 mph for top speed does not affect acceleration very much. I said earlier that the only signifficant difference in acceleration is the extra long gear ratio availiable for the Diablo 6.0. but even this only affects the 1/4 mile by 0.2 seconds!

Diablo 6.0 (normal ratio 62 mph in 1st gear @ 7500 rpm)

0-60 mph: 3.4 seconds
1/4 mile: 11.8 seconds @ 121 mph

DIablo 6.0 (extra-long ratio 68 mph in 1st gear @ 7600 rpm)

0-60 mph: 3.6 seconds
1/4 mile: 12.0 seconds @ 119.8 mph


But I am pretty sure Diablo Jota has the normal gear ratio like the VT and 2WD. It is not much difference from the short GT and SV gear ratios. F40 Le Mans, you have driven the Diablo SE30, right? Are the gear ratios the same as the VT?

 Well, interesting argument!!!
I have not never drived Jota (only 12 products, my friend possess one in Italy), but I have drived SE30!!!
The difference to wrap length of gears ratio is a lot important, cars little heavier with little little power, if with shorter ratio, they can turn out faster!! It is difficult to explain in writing, in any case:
SE30 Jota has more up maximum power approximately 300 rpm of the VT and 2wd, therefore they turn out gears little longer, but the usual gears ratios (to those days did not exist different gears ratio for Diablo) and Jota catches up 333km/h against the 340km/h from the Factory.
Today Diablo GT has available 3 gears ratios: 320km/h; 330 km/h; 338km/h; and that from 330km/h it is the same one of the Jota, that is medium!!!!
perhaps but for the Jota, Lamborghini declared 340km/h because perhaps a little better Cx aerodynamic regarding the GT, but did 333 in truth!!!
Theoretically if Jota had the same short gears ratio of the GT from 320kmh (which is applicable) the Jota would arrive to 20,8s on the 0-1000m turning out still today the faster Diablo!!!
I do not share with you, Jackamo, when to say that exist little difference between short gears ratio of GT and SV against that one of the Jota,
it watches here:

JOTA (km/h):
1°: 101.4
2°: 152.9
3°: 208.4
4°: 257.6
5°: 333.1

GT(short-ratio):
1°: 88
2°: 134
3°: 182
4°: 232
5°. 320

2WD - VT(**) (same gears ratio, but two different tests):
1°: 99-97
2°: 150-147
3°: 204-200
4°: 259-254
5°: 325-325

(* *) to vary changing at 7000, 7100 or 7150...

exist much difference between Jota gears ratio and GT “short” gears ratio!!!
GT with long ratios to have gears longer than Jota!!!!
SEJota to make 0-1km in 21,2s with the same gears ratio of 2wd (492hp), than to make 22,4s (21,9s for VT)!!!
and GT to make short 21,0s but with gears ratio!!!!!
