Hrmm....

I dunno. I'm sure its launching hard, but 3.65, that's faster than a Lambo with 4wd. I think the numbers are inaccurate.

It would mean you are roughly doubling the friction cooefficient of the tyres, and I don't see how this is possible....

well... I see where your going.

The fact is, the PDA measures inputs from the OBDII port. It tells the program when the tyres start turning, it tells them when it reaches 100kph ( 60mph ) None of this G-Force gtech business.....

There's more than one way to skin a cat.

This has got me thinking...

Ground speed and wheel speed are two very different things. Breaking traction in second gear will get your tyres hitting 100km/h a lot faster than the rest of the car does!

That is true, but Correvit timing or other devices such as GPS measure land speed, not wheel speed.

Well, on any old road a lambo will do a 3.6s 0-100 and 11.5s 0-400 quarter mile, all day, every day. Motor mag alone reproduced an 11.7 on an airstrip, in 37º heat, 90% humidity, on very abused tyres.

Not exactly a racing surface, though possibly better than your average road.

It reproduced similar times every thereafter.

It didn't need race fuel, it didn't need a special map to be used, and it didn't need anything other than a mash on the brake, a mash on the throttle, then a releasing of the brake to do so. This takes roughly the same time it takes to clutch in, rev to 5 grand, dump the clutch in your normal manual car. It was just too easy...

If you both started the PROCESS at the same time, then you wouldn't even have any boost yet, and when you did, the lambo would already be 30 meters ahead of you, diong 40km/h.

But, you would crash tackle the raging bull on the strip... You could toy with it and ease off for half a second at quarter track to even it up, and you'd still come around him. You see, your top end geea is where its at. In a perfect run, you would have around, by my rough head calc, 9mph on a Lambo. that's alot and just goes to show where its time comes from... Its start.

But on a track, it would also have a better start, and would also get close to breaking 3s to 100 (due to roll out).

But having a monstrous, unforgiving surge up top from a big turbo that, on a normal road would simply amount to roll on wheelspin in 2rd and 3rd gear, is something else alltogether...

So you can see that I'm not saying you're crap, geea/F6_UTE, its just that sometimes I just feel that your feet leave the ground a little, this is one of those times to come back down to terra firma and think about the physics of it. Considering physics hasn't been wrong in a very long time (ie, ever), I don't think it feels like being wrong now....

So my point is this; at your average street light tickle, a lambo has it, just.

You simply cannot defy physics, or decades of practical racing examples.

Best way to solve the arguement is for someone to grab a Lambo and line me up at a set of lights. :thumbsup:

Geea. :nono:

Hold on I'll just grab the keys..................Honey, have you seen the keys to the Lambo...............no not those ones there for the 430. :innocent:

Absolutly steve. I told you in page one how to 'beat' the software. BUT it shows up.

You cannot run 0-60mph in 3.6 odd seconds with wheelspin, and carry on to run to half track at 91 mph in a squidge over 8.0 seconds. As soon as your tyres hook up, your ground speed vs gearing will cause the car to bog down, and the graph would show this. You can do it on a downhill stretch of road, but look at the terminal speed and ET, downhill, I've run 4.3 seconds and 11.3's.

The figures DO add up. I have finally got the thing to catapult out of the hole on the street.. The track, with it's different grip characteristics will make the car behave differently.. It has not got Everything to do with power alone.

Like I said, my driving, the F6 Gearing etc helps it to 100 quick. It will not carry that thru to the end of the track because the gearing is all wrong for 1/4 mile, period otherwise Simon would have dropped a 10 with his 412rwkw. Think about it logically.. Adam with 3 gears, 430rwkw runs 9.9*. Geea with 380rwkw and 4 gears runs 10.** all day.

Auto BF 6spd, but uses tall gearing runs 13.1/2/3 stock.

power alone will not run a fast 1/4.

Oh, and the ute got sideswiped today. ^%*!!!!!!!!!!!!!! but I'll trundle out now, vid in hand and try my best to get something on tape for on my way to the smash repairers..

FARK!!! what happened who hit it?..... :spoton:

<{POST_SNAPBACK}>

Mmmm what led to the smash? Was a cardinal rulz was broken by Ben :fool:

1) Never park your vehicle in a shopping center car park.

Shopping centers

Woman with screaming kids in car

BMW drivers

And F6 Tornados don’t mix sadly. :tease:

The panel beater will fill it full of BOG and slow it down even more hahahahhaha

Or could this be another ploy to avoid a run-off with the camel?

A couple of my boys wanted Subway for Lunch, so I called in on my to them way to get them some. I never usually park in centres where it's a possibility to get smacked, but I was in a hurry.....

Lawsy, my car has run an 11.1@125 with pump fuel and in full street trim. My Michelins are a very good tyre and I still reckon that at a set of lights on a dry road I would be able to win. The thing with lights is I can still get my car loaded whilst we wait for it to change. I can't load past 2000rpm as it will spin on most roads, so it doesn't take much to load it. If we both mash the brake and then the gas that should do for me.

The other thing your not considering is the drivers. How many of the people with these cars can actually drive them? I know I can drive mine.

Like I said earlier, if you're able to organise 1 in Melbourne somewhere I'll give them a few runs. :thumbsup:

Geea. :spoton:

Call Sam Newman, he's cocky enough to try and with his racing [cough] experience he should have a fair idea how to drive.

Ahhh crap!! Sorry to hear about the prang :thumbsup:

I see what you are saying about the timing and the figures on the PDA. I re-read the original post about how it shows up on the graph. Excellent results to be getting and I'm very interested in this "technique" you are going on about. I consider myself to have excellent gear shifts in the T5 so any little tips and tricks I can get will only refine this even more.
