Default I find this really weird...

Please note, this is probably due to a lack of skill on my side.

A mate of mine from work today wanted to drag me in his VN commy which is on gas.

We did it down a quite two lane road. Only to 100kmph.

Oddly, he killed me. His car is somewhere round the 105KW mark.

Was I doing something extremely wrong? I did always get close to him but it seems he was a good 15 - 20m ahead of me by the time i stopped my car fish tailing and straightened it out.

No matter what I did it would always happen. I tried accelerating, letting off then acceleratin again and it just kept slipping it.

Is this due to my near bold tires and the wet conditions? Or was I doing something wrong?

And guys, i know street drags aren't exactly looked well upon, but every once in a while i'd like to have some fun.

Wet. Tires play a big part too, i have decent tires and it spins with ease.

Try it in the dry, getting power to the ground in the wet it always going to be difficult.

I agree with seven, get some decent tires and try it in the Dry.
I have knocked off VN's on my 2.0L Twin Turbo, 0km/h - Speed limit.

Just makes me sad that i got thrashed my his shitty 3.8L naturally aspirated engine and i've got a 3.0L Turbo..

Giving him a rematch today, swapping my front and back tires.

Hopefully i don't get thrashed again.

First of all i need to make the point very clear, as you're well aware.. that z20soarer.org does not condone street racing in any form and believe me, police have been monitoring this site (i've logged IP ranges that appear to be coming from Police domains) so be very careful what you say on a public forum. That said we've all been guilty of a little hoon behaviour from time to time so i'll let it slide this time.

However to answer your question, based on the scenario where you are dragging on the yet to be built Adelaide quarter mile dragway sometime in the future, your tyres are your main problem.

Tyres are probably one of the most important things you buy so choose wisely and don't skimp out on them as they're the one thing that holds your car to the road. Secondly wet weather is not the place to be dragging. I won't even hit up the Motorplex in the wet because its not going to give me optimum times. Your problem is that you couldn't catch traction. That said his Open centre VN should have been fishtailing too, so unless he had a ton of bricks in the boot I don't quite get why he caught so much traction and you didn't.

Also don't swap your front tyres around. those are your control tyres that you use for steering and are very important. if you lose traction at the front end you will have NO control over the vehicle. simple physics..

Hmmm define good tires? :S

Also, we only did - 100kmph on a road where that's the speed limit so i'd think that's all legal.

His advantage i think is the fact that he has brand new tires:S

And it loses a fair bit of power coz of the gas.

And yeah, I understand that we don't condone it, but i'm kinda hoping that this is still within legal limitations...and those of our forum.

I run Maxxis MAZ-1's. At nearly $200 a corner they are an incredible tyre for the price. These are awesome, the cheaper MAV-1's aren't too bad also but not nearly as good as the MAZ's. Federal 595's I hear pretty good things about too.

You want to stay well away from Nexen/Nankang's/Bob Jane All Rounders etc..

Some guys i know have spent upward of $400 a corner though and have incredibly sticky tyres for their money.

Gas will only make a vehicle lose 15% of its power by the way.

BTW it might be a 100kph speed limit but they'll still ping you on hoon laws (oh wait you dont have those yet do you...) for attempting to push a vehicle to its limits. I've been pinged in SA before for reckless driving + making excessive noise for something as simple as a tiny U-Turn in Hindley St once upon a time to nab a parking spot on the opposite side of the road. Yeah.. very gay. Of course I walked on it because the cop was a fucking douche and the court said he was a douche too.

I guess, but yeah we have no anti hoon laws here in adelaide et ( not that i know off.) and seeing as my car is bare stock, it's really not that loud.

Loudest thing on there is some annoying noise coming from my engine that i cannot figure out what it is.

Ham, what size are your rims? would that affect tyre prices? I've only got 16s

Another thing that can make you loose traction is due to open wheeler and im guessing you do have one.

such like me 1J + open wheeler = not traction at all.

Hammy should know aswell???

you think??

to make sure it does.. jack up the rear spin the wheel if both wheel spins the same way you spinning it then its LSD, if one wheel spins one way and the other wheel spins the other way then it dont have LSD.

Another way to check is the on vin plates where it says axle, if it got G284 then its LSD if its got G254 then it dont.

yeah. That info is on the firewall plate where its written axle code. I think g254 and g284 diffs are in gz20's only though i could be wrong on that one.

Err... slightly wrong there on the info guys.

The last digit of the axle code on the firewall plate denotes the number of pinions (spider gears) and whether the diff is open or lsd.

An odd number = LSD (3 for 2 pinion diffs, 5 for 4 pinion diffs)
An even number = open (2 for 2 pinion diffs, 4 for 4 pinion diffs)

This is only applicable to G series and I believe F series, possibly T series also, but as Soarers don't come with them, who cares

The two numbers prior (25 and 28 in this discussion) denote the ratio of the diff. 25 being 4.556:1 and 28 being 4.3:1 I think.

For a full explanation, it pays to keep this URL in your favourites which I refer to for confirmation of diff ratios, the rest I've pretty much memorised now.

you also can get done for excessive accelleration(drag racing) at any speed

you dont need to break the speed limit to get done for racing, and the cops have a book about 1.5 inches thick full of charges they can get you for.

There are hoon laws in SA.

I was in the car when my mate got caught street sliding in his caged s13, got impounded under the "Hoon Legislation Act" or something similar.
