I agree, yet at the same time disagree with getting out on the road to practice/get a feel for the car and what will happen.

I have done it before and you do get a bit of a better understanding for whats going to happen or at what point will things start to get hairy. Tho in todays times u gotta be careful with all this hoon bullshit.

aquaplane: more rubber = greater chance of it happening. You need to go over puddles not just wet roads... I cringe when i see water running across teh road! (N)

as for learning... i learnt that 3rd gear, wet roads = 180km/h wheelspeed when wheelspinning... and it takes a lil bit of time for it to slow down too

completely irrelevant to this topic but how the hell do you get 180kmh showing in 3rd when the gear only goes to around 140? Ive reved it out in 3rd in the wet but ive never wrapped it off the speedo...(like I said, irrelevant question but hey its 4am what do you expect?)

bump for the % and effeciency of tyre tread, as opposed to the actual width of the rubber.

I only have 235's at the back, and the car is happy going thru puddles at any speed when the tread is new and deep. Because of the camber at the back my insides wear much faster, and when the inside half of the rear tread gets past the minimum tread depth as indicated by the markers, then it aquaplanes and squirms and jiggles like crazy over ANY standing water, even driving over a light stream of sidewash (water flowing across the road due to surface camber etc) makes the car jerk disturbingly to the left and right at the rear as the wheels at the back become unsettled at anything approaching 90kph over this water.

My brother tells me that its the HICAS going crazy because its wet, but I slap him on the head and point out that as each wheel at the back lifts up (They hardly ever both lift at the same time) the toe-in on each side will push the car towards the aquaplaning side, then vice versa as the water is traversed.

At freeway speeds its enough to make the car lurch suddenly and shoot half into the next lane over and is as scary as heck.

I have had my R33 for over 7 years and this is FACT, dont argue.

Any tyre will plane if you hit enough water at a speed that wont let the water flow outwards and away from the tyre. If you mount directional wet tyres the wrong way around you are actually channeling the water into the center of the tread where it will bottleneck and start to lift the tyre, something you could deftinatly do without.

Similarly, If your tread has a poor footprint (sides worn like mine) then the tyre becomes less and less effective as the flow patterns stop working properly.

Think physics people!

Nein, although wide tires are a factor in deciding their tendency to aqua plane, even more of a concern is tread pattern. If the tread pattern is good at shedding water, you will not aqua plane as easily as a car with poor wet weather tread pattern - regardless of width.

Yep I missed that one. and you're absoultley right.

culodofsomke: I think you'll find there is a disclaimer in my signature that nothing I say should be taken seriously.

But really, what's not to understand? It's all there in plain english.

Try racing in the rain with slick tyres!!! Rain tyres not much better in the kart but helps turn in....best driving lessons I ever got is from racing in the wet. :D

Agree totally about karting in the wet teaching you car control, but you can't really apply the same principles on the road. In the rain in a kart you drive OFF the racing line (around the outside of the track where there is less oil etc.). I don't think the authorities would look very kindly on you driving on the footpath just because it was raining :D

My van aqua planes with 195's, my VL aqua planes with 225's... Erins car doenst aqua plane on 255's... On identical sections of road at identical speeds (or more, the bloody hoon she is)

:D

It's true that wider tyres would be more conducive to aquaplaning but like Krawler said, tread pattern and especially TYRE WEAR are the biggest factors by far.

I totalled a car aquaplaning around a corner on quite narrow tyres not long after I got my license, the problem was the tyres were almost bald.

That was twelve years ago, since then I never drive on bald tyres and I've never aquaplaned again.

You guys have to be kidding wet weather is the best time to drive because it separates the men from the boys and when you aquaplane that just brings more fun into it

Sounds like the attitude I used to have when I was a man (and much younger and thought I knew it all)

I guess now I'm just one of the boys (older and wiser ? ).. as I've learnt that it doesn't really matter how good you can drive or think you can drive .. hit a big enough sheet of water and start aquaplaning and ur just there for the ride, so hang on. I guess some ppl will just have to learn the hard way tho

I aquaplaned on the western freeway (outbound at the moggil rd overpass) many years ago (about 2 months later they decided they better fix the road) it didn't end well, about a 50k insurance bill. This happened when travelling at the speed limit so I have learnt that it's a real danger without adding excess speed to the equation.

Any of you men out there that wanna experience the fun of aquaplaning should find urself a suicidal mate .. jump in the passenger seat and get him to drive at 90km/h at a brick wall. That helpless feeling you will get as your about to hit the wall and you have no control over the outcome, that's the feeling of aquaplaning

keep it sensible .. respect the weather

I both agree and disagree with you on that :)

I agree that aqua planing can happen very quickly and depending on the volume of water, it can be basically uncontrollable until your tires clear enough water to gain grip.

I disagree that it doesnt matter how good you can drive etc. Because my van is so bloody terrible at aqua planing, I've started taking a much greater interest in the condition of the road ahead when its raining. Its quite easy to spot potential aqua plane points, although not always easy to avoid them :rofl: The big ones are flowing water (accross the road due to camber/hills etc) and the "train track" effect left by heavy trucks on the road filled with water, more so than simply puddles - at least in my experience? By driving outside of the "train tracks" you can quite easily avoid aqua planing in that situation, although flowing water tends to be another issue all together. I've found the best option (in the van anyway) is to back off the accelerator as soon as you see the water coming and coast through it. Dont brake, dont turn anymore than you absolutely have to, etc. Dunno if this is the "correct" way to deal with it, but thats what I've found works the best in my HMAS Work Van (ahoy captain, set sail for the guard rail! Arr me hearties)

The other thing I reckon is that wet weather definately seperates the "good" drivers from the bad! I give massive props to people who can actually drive in the wet, which is very few. The thing that makes me cranky as buggery is when people slow down on roads like the M1 (eg: a damn good road) to 90kph or less, and then tailgate - thus totally negating the positive effects of slowing down! Whats the point of slowing down to help compensate for the wet roads in your stopping distance, if you are gonna totally fsck it by tailgating? On the flipside, people who speed through 90kph traffic doing 110kph+ is also dangerous, as the constant chopping and changing of lanes simply increases your chances of hitting a car thats less visible cause of road spray etc.

Just relax in the rain, drop your speed to suit the conditions (although lets face it, you could easily do 110kph on the M1 even in a blizzard its such a good road, pity brisbane drivers are so arse), leave a good 2 second following gap and go with the flow! RACQ had an article a while back that "going against the flow" (ie: going slow when others are fast, going fast when others are slow) was far more dangerous than "speeding" (ie: going faster than the little black number in the red circle) and I agree with that 100%! Theres no point being an amature policeman and sitting in the right hand lane at 80kph in the rain because you feel thats the fastest speed people should be doing....

Ok I stop ranting now

lol we live in a cointry controlled by drought and we are all talking bout wet weather driving.

i mean serious fellas how often does it rain in brisbane like 3 or 4 weeks out of the year

Hey you know what I just thought...

Give big big gaps in the wet... IE 4-6sec gap at least. Dont sit next to other cars, or in their blind spots, and you shouldnt have a problem unless you do start to plane.

Now if everyone applied these principals in the dry as well! :) ahhh wouldnt the world be a much happier place.

Theres no point being an amature policeman and sitting in the right hand lane at 80kph in the rain because you feel thats the fastest speed people should be doing....

"Driving in the right lane on a multi-lane road with a signposted speed limit more than 80km/hr (without an excuse)" 2 Points and $45

Pitty the cops NEVER inforce this rule. Whats the point of even having the rule if nobody inforces it :rofl:

    • Well, after the full circus this week (new gearbag, 14 psi actuator on, injectors and AFM upgraded, and.....turbo repair) the diagnosis on the wastegate is in. It was broken. It was broken in a really strange way. The weld that holds the lever arm onto the wastegate flapper shaft broke. Broke completely, but broke in such a way that it could go back together in the "correct" position, or it could rearrange itself somewhere else along the fracture plane and sit with the flapper not parallel to the lever. So, who knows how and when exactly what happened? No-one will ever know. Was it broken like this the first time it spat the circlip and wedged itself deep into the dump? Or was it only broken when I tried to pry it back into place? (I didn't try that hard, but who knows?). Or did it break first? Or did it break between the first and second event of wierdness? Meh. It doesn't matter now. It is welded back together. And it is now held closed by a 14 psi actuator, so...the car has been tuned with the supporting mods (and the order of operations there is that the supporting mods and dyno needed to be able to be done first before adding boost, because it was pinging on <<14 psi with the new turbo with only a 6 psi actuator). And then tuned up a bit, and with the boost controller turned off throughout that process. So it was only running WG pressure and so only hit about 15-16 psi. The turbo is still ever so slightly lazier than might be preferred - like it is still a bit on the big side for the engine. I haven't tested it on the road properly in any way - just driven it around in traffic for a half hour or so. But it is like chalk and cheese compared to what it was. Between dyno numbers and driving feedback: It makes 100 kW at 3k rpm, which is OK, could be better. That's stock 2JZ territory, or RB20 with G series 550. It actually starts building boost from 2k, which is certainly better than it did recently (with all the WG flapper bullshit). Although it's hard to remember what it was like prior to all that - it certainly seems much, much better. And that makes sense, given the WG was probably starting to blow open at anything above about 3 psi anyway (with the 6 psi actuator). It doesn't really get to "full boost" (say 16 psi) until >>4k rpm. I am hopeful that this is a feature of the lack of boost controller keeping boost pressure off the actuator, because it was turned off for the dyno and off for the drives afterward. There's more to be found here, I'm sure. It made 230 rwkW at not a lot more than 6k and held it to over 7k, so there seems to be plenty of potential to get it up to 250-260rwkW with 18 psi or so, which would be a decent effort, considering the stock sized turbo inlet pipework and AFM, and the return flow cooler. According to Tao, those things should definitely put a bit of a limit on it by that sort of number. I must stress that I have not opened the throttle 100% on the road yet - well, at least not 100% and allowed it to wind all the way up. It'll have to wait until some reasonable opportunity. I'm quite looking forward to that - it feels massively better than it has in a loooong time. It's back to its old self, plus about 20% extra powers over the best it ever did before. I'm going to get the boost controller set up to maximise spool and settle at no more than ~17 psi (for now) and then go back on the dyno to see what we can squeeze out of it. There is other interesting news too. I put together a replacement tube to fit the R35 AFM in the stock location. This is the first time the tuner has worked with one, because anyone else he has tuned for has gone from Z32 territory to aftermarket ECU. No-one has ever wanted to stay Nistuned and do what I've done. Anyway, his feedback is that the R35 AFM is super super super responsive. Tiny little changes in throttle position or load turn up immediately as a cell change on the maps. Way, way more responsive than any of the old skool AFMs. Makes it quite diffifult to tune as you have to stay right on top of that so you don't wander off the cell you wanted to tune. But it certainly seems to help with real world throttle response. That's hard to separate from all the other things that changed, but the "pedal feel" is certainly crisp.
    • I'm a bit confused by this post, so I'll address the bit I understand lol.  Use an air compressor and blow away the guide coat sanding residue. All the better if you have a moisture trap for your compressor. You'd want to do this a few times as you sand the area, you wouldn't for example sand the entire area till you think its perfect and then 'confirm' that is it by blowing away the guide coat residue.  Sand the area, blow away the guide coat residue, inspect the panel, back to sanding... rinse and repeat. 
    • The detail level is about right for the money they charge for the full kit... AU$21.00 each issue, 110 issues for a total of $2,300 (I mentioned $2.2K in the first post when the exchange rate was better). $20/week is doable... 😐

    • You put the driver's seat on the wrong side! Incredible detail on all of this. It looks like you could learn a lot about the car just from assembling the kit.
