None of the Radical guys (or any of the others) used them at Adelaide or Wakefield (where the temps got below zero overnight), all that it took in the mornings was start the car and let it run for a coupe of minutes. You are usually doing a walk around of the car at the time, checking for leaks or any other issues with the car.
-
I would not bother with it Dane, every one that I have dealt with has been up to operating temp within 2~3 minutes of idling time, even less if it is moving with a bit of load on. The amount of time and energy spent setting one of these units up (with the attendant risks of leakage) is not worth the possible savings in rebuilds. That system also appears to only do the coolant, and not the oil, where the oil is the more important fluid to get to temp quickly.

Autobarn, Burson, Repco, Supercheap, etc.
I think that they are usually around $40 a set, I haven't needed to buy a new set for a while, so I am probably wrong on that price.
-
Make sure that they are not a specific construction to cope with the "unique" layout of the Porsche Cup Cars, I am aware that the euro series do have their own spec Michelins, I'm not sure if it is the same here.

$8500, complete with a number of storage compartments and benches internally, 4 wheel electric brakes with breakaway system, new tyres and wheel bearings, 240v internal lighting, 50l water tank and a 20m retractable airline.
It is also internally beaver tailed, to make the loading height lower.

Definitely, but unfortunately they're out of the budget at the moment! An encloseed Nevco would be great, but 20k I don't have 20k burning a hole in my back pocket. So I'll use an open trailer for now and avoid leaving it out overnight, and cover up the intake and cockpit when towing.
How is your car coming along? Have you purchased an enclosed trailer for it?
Picked this second hand trailer up a few years ago, I need to do something about the stickers on the side of it as they have actually melted into the paint underneath them, it's tall enough inside that I can walk around in it easily.
The car itself is getting closer to being finished, I had a few little setbacks and rule changes to deal with that resulted in undoing changes that I had made to the car to make it legal for the old rules.
-
Funky, you will find that with a car like the radical, that an enclosed trailer is much more suitable than an open one.

Webbers problem on the Bolte is that the FIA brought in a new rule this year that allows for the removal of a drivers super license for non sporting related issues, so if Mark had exceeded the speed limit, and the police decided to prosecute him (using Victoria's draconian regs) then Mark would have most likely ended up losing his super license.
-
Absolute is measured from 0, whereas gauge is from atmospheric (101.3kPa, 1 bar, 14.5psi) as a base. A lot of the euro cars quote absolute for inlet pressures.
-
turbos must run standard boost which in an evo X is 1.6 bar.
Is that an absolute or gauge pressure?
-
Got caught out once with the not locking the coupling into place, I now use a small padlock on the locking tab, and I leave the key, on the same key ring as the car keys, in it when hooking up the trailer. This means that I can't start the car without getting the keys out of the lock, and verifying that I have attached the trailer properly.

I have two of the same cars that Mark has!!!! unfortunately they are the X5 and the Navara...

I have seen a totally unmarked, undercover police Hiace van.
Was filling up at a petrol station, on one of my country runs, saw a policeman walk out of the shop. Thought to myself; "i didn't notice a cop car around", he then jumped into a plain white Hiace van. It even had the small blue and red lights in the grill.
That may have been a forensics van.
Saw a Soccer Mums SUV pulled over on the Calder Fwy just outside Kyneton at the start of summer with the bonnet up, baby on board sign on the back window and hazards on. Like the lovely person I am (although running late for work) I stopped, expecting some mum and bub had over heated on the way to Melbourne....only to find it was Mr Plod (I realised this as I got out of the car and noticed the HUGE camera plate over the bull bar)
I felt as if my good nature had abused...and they wonder why people don't stop to help others
The cops used to do that around the Yarra Valley, park a beater that they had gotten from the wreckers at the side of the road on a jack with a wheel off, making it look like a breakdown, until you went past and saw the camera. They stopped doing it after the local rag exposed it and proved that it was against the rules at the time.

Ii have just recieved an email back from a friend of mine, who happens to be the Michelin tyre engineer for one of the ALMS teams ( he has asked me not to say which one, but they did win one of the championships last year ) his response to this queston is that if you want the tyres to last, such as for use in the actual race, then do the slow heat cycle build up, and store the tyres for at least 24 hours, if they do not have a compound or construction change for the following race, then they bed thetyres in the previous races practice sessions and then store the tyres to allow them to totally cure.
However, for outright quickest laps out of a set of tyres, then go for the green tyres, a lap or two too scrub them and then do your flyers. This will give you the quickest results out of that set, but the heat load put into them will cook the tyre too quickly and they will only come back to about 80% of a properly bedded set.

Most of the Japanese utes are like that, Toyota used to supply all of their test Hilux's with 500kg's of sandbags in the tray, to "give journalists a real world feel for the vehicles handling" but mainly to hide the stiff rear spring rates and resultant oversteer biased handling caused by not enough weight being over ther rear wheels.
-
The piece of armco railing pierced the car, causing most of Kubica's injuries.
-
Apparently the gaurd rail punched a hole through the front of the car into the passenger space.

-
Major sculpting on those sidepods.
It's also interesting that they have a GoPro mounted on the rear wing.

I'll sell you my ST-R D22 if you want...

Dl1
in Motorsport
I can't release a lot of information, technically I should not have seen half of the gear that I did see.
DL1, more ports and SD cards now, USB connectivity, switched output ports, new faster processor.
DL1Pro, Mil spec connectors and water resistant case.
DL2 has some hardware updates, more major ones later in the year.
Dash 4 Pro, a fully configurable dash along the lines of the Motec MDD.
There is also a number of incremental upgrades to other products in their range.

You also have to factor in a rebuild of the dog rings and other components in a sequential shifted box every 5,000 k's or so as well, this is usually in the 2~3,000 range.
-
If the new tyres are capable of applying (figures used as an example) a constant moment of 100Nm to the differential and the plates can only hold 95Nm, the extra moment will be enough to overpower the friction internally within the plates and thus making the diff work more as an open unit, but worn tyres can only provide that figure at maximum Fy and Fx, thereby not providing enough load consistently into the differential to overpower the clamping force of the ramps, causing them to lock and unlock dependent on the transmitted load. When the diff is locked then it will cause under steer on turn in and over steer on exit. It may be the due to the old diff being worn out, that it was not generating full lock under loaded conditions and masking the issue.
Engine Pre-Heaters

Your stuck with your 30 hr rebuilds no matter what happens (unless you buzz the engine and get a yellow dash light) so whilst running the pre heater might save you somewhere around 30min of total run time over that period of time, if you are that concerned then you are going to have to manually move the car from the pits to dummy grid, shut down on the grid, etc. From what I have seen, the rebuild times might be on the short side for the engines in the Radicals, The engine in the Speads has done more than that with no lose of performance or cylinder pressures.
