0 - 60 MPH

[rweir]

I all ...

Tried a few 0 - 60 times the other night .... best I got was 3.94, this was actually up a hill! Felt I got better traction ... Potenza S-03's

Anyone got the 3.7 yet ?

Only in my dreams!

Wow -that is mighty impressive! Especially up a hill!

I shouldn't do it too much of you want the thing to last!

Thanks! and I agree! Although, I have a modified Audi S4, and to get a good start with that it is full revs and side step the clutch, now that hurts, you just feel metal bending and you know you have just reduced the lifespan

This looks like the ultimate race line-up! Love the Maclaren F1 Gulf - it must have been raining as the wiper moves, nice!

The Audi TT is dead. No surprise there then.

To get under 4 with any mechanical sympathy you have done really well.

[kinetic]

What equipment are you using to take the timing? The BHP figure you indicate, is that at the wheel? or a flywheel estimate?

[kinetic]

Sorry, also just noticed the figures you posted show 0-50 in 3.94 not 0-60 is this a typing error?

[joust]

I'd imagine he's using a DL90 or similar datalogger. BHP is calculated and requires a "zero reference" run and hence should be taken as a guide (like most BHP figures ) - but is very useful when comparing like with like.

I know, shame they don't do a 3R... maybe I'll email cargifs.com!

[rweir]

OWE!!! Just looked, not a typo, must have been wrong and it timed me to 50 instead ....

Feck!!!!

Right, I am going back out to try again !! Now I feel like a dipstick after showing off like that

For your info this is the datalogger that I use ...

This is the data from my best run in my old Caterham Superlight R...

10 0.66 4 0.75 25
20 1.37 20 0.61 43
30 2.03 44 0.72 77
40 2.6 73 0.82 119
50 3.2 113 0.7 132
60 4.09 184 0.58 140

(speed/time/distance/g/hp)

Should give you something to aim for!

You peak G figure of 0.87 is very impressive. I had an Impreza that did just over 1g, I haven't seen a two wheel drive car on road tyres get past 0.9g yet.

Ah - AP22.

Do you have the GPS?

If not it inherently gets "inaccurate" after a few seconds due to interpolation errors - but still fun never less and not bad overall figures - but certainly shouldn't be totally relied upon - the accuracy is given by RL at www.race-technology.com/WebPage2/Products/AP22/AP22Spec.html

DL90 recognised the issues with just accelerometers and added the optional GPS to the AP22, and have a cracking box in the DL90/DL1 - close to the VBOX for about 1/4 the price.

[rweir]

I have GPS, but only for speed ...

Had a look through the other runs I did, this is the best (see below), this is a 60mph top speed!! (mind you, not 62 mph?!?!)

Also, I wonder about the top speed of 175mph, I have had just over 160 GPS out of it .... not doing anything more. I also have an Audi S4 which I have had 170 GPS out of it, and it pulled strong up to 160ish then a bit slower up to 170, the noble just does not seem to want to go higher, unless I have the length of the country to try!

So, best practice to get 0-60, try and get maybe a little wheel spin to get it going then go for it, hopefully no more wheel spin ? suggestions?

PS. The peak G force is quite a lot in this run!

A bit a wheel spin can't be a bad thing. Lower tyre pressures may be a route too.

I have to say getting that close to the book figures is good going.

Those latest figures are pretty good to be honest. Launching to 30 in 1.9 sec is a good time and I don,t think you'll improve much on that without potentially destroying your clutch.

Have you set the vehicle parameters within the AP22? ie. weight, tilt factor, roll factors, etc. because those HP figures look way to high for a Noble. especiaLly since they are measures of 'at the wheel' HP.

[rweir]

I have not put in the details to get the correct HP figure out ... I did not have the time, or could not be bothered! I really just wanted the 0-60 times ...

Next would be the 1/4 mile! but I don't have access to a road that long really ... anyone know what the 1/4 mile for 3R is?

I think the 4.22 is about the best I can get, but I am not too conserned since I seem to be able to get close to that most times so thats what counts, I may at some point get a good 3.7, but if I can't replicate it, it's no good!!

You're better trying 0-70, so you can get a 30-70 figure which will more accurately reflect whether your car is peforming in line with the independent test figs from the magazines. Even if you get a crap launch your 30-70 fig. will not alter more than a tenth or so.

I've used the AP22 with my EVO6, Lambo Gallardo and Lotus Exige and the figs make interesting reading.

The Evo is quickest to launch and to about 40 mph (o-30 1.82) but from there on the Gallardo destroys it.(Gallardo is e-gear so difficult to get off the line quickly)

The Exige is considerably slower than either to be honest.
