Ok I have had my fair share of fast cars in the past.

Was thinking today what sort of power would the vq require to light up all 4s from a rolling start?

I have been in fast awd cars where you plant it and its 4 wheel light up s down the street.

Rolling start? I can only do it in the wet, unless you had some really crappy tyres you would be struggling in the dry.

Mine chirps into 2nd and 3rd in the dry, but only due to the stupid line pressure the current box is running. It's surprising how much power it can put to the ground actually.

Whats your specs scotty?

I browse iff my phone so hard to navigate around here.

would depend on trans a lot, autos are a lot smoother,so its less likely to happen, manuals have a harder transition between

gears and upset tyres more, its the sudden shock that gets thems spinning in the first place, and once a tyres unloaded its

easier to keep it there

c34 rs4s is 1650kg apparently

m35 should be around the same as it has a lot of alloy in it (block, rear subframe, bonnet?)

also my rs4s will do it with a big drop in the wet, i doubt an auto would do it in the dry without a huge amount of power

i went to drop off some scrap metal the other day, so i had to pass through tho weight bridge.

on exit when i unloaded the c34, it was me, my gf and bit less than half a tank of fuel and the car came in at 1720kg

So thats my factory stock rs4s no sunroofs no leather.

So if we minus, me 73kg, my gf, 45kg and whatever is left in the tank, 20l roughly

that takes the stagea to 1582kg roughly dry weight.

Still a bit heavy but ok

Mine was just under 2T on the Phillip Island track weighbridge, with two fat pricks (Aaron and myself) sitting in it, with a full tank. I have added a bit of weight with coolers and bracing, bigger brakes etc but the Bride seats are lighter than the stockies.

I just weighed Craig's old electric seats, they are 24kg each on the rails.

I just can't see it happening in the dry without 500kw+, which I assume is difficult in an m35. straightforward obviously for a c34.

Mine happily wheel spins as it comes on boost in 1st, 2nd, 3rd and sometimes 4th on a hill or with a trailer on the back....as long as it is wet. In the dry it's hard to even chirp second.

My car is 1800kg with me in it - RB30, towbar etc. Can't see me spinning all four with quality 255 tyres - not prepared to dump the clutch in the dry as I would worry about breaking something before the wheels will spin!!

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
