Hey guys. I just saw the michellin ad talking about their Tyres saving you on petrol. Not considering them for my skyline but just curious if anyone knows how much of a difference they make? I don't see there being any significant impact based solely on Tyres

sounds like another marketing scam to suck all the hybrid and small car owners

Yeh, super hard tyres with extreme pressure have less rolling resistance, so in theory will save a bit of fuel.

On that note, Mythbusters last night tested the theory of tailgating a truck to save fuel. We all knew it would work, but I was surprised that they achieved nearly 40% fuel saving by following at 10 feet (3m). When they dropped it to 2 feet the fuel consumption actually went up. They claim it was due to the constant modulation of throttle to maintain such a close distance, but I reckon it's because they were almost under the truck so the slipstream hadn't had a chance to properly mix, and they were still getting a lot of "clean" air from under the truck.

Anyway, it was their usual highly questionable testing methods, but made for entertaining viewing anyway (although nothing got blown up, so they must be getting soft in their old age)

yes ^^^^^

but if you follow a truck on say - a highway... your fuel consumption goes down but you gain

stone chips

cracked windscreen

poor visibilty cos can't see past the truck

dangerous

annoying driving behind a truck esp during acceleration

not really worth it to save a few dollars a week!!!!

this is what annoys me - people who can't afford to run a car - yet insist to own a car... why not get a pushbike? or even motorbike?

Der, no shit sherlock. They weren't actually advocating that you should tailgate trucks (in fact quite the opposite). They were testing a myth because it's what they do. You know - myth busters?

If people read my post and want to start tailgating trucks to save money then that's a good thing. It will help clean the gene pool.

derrrr you idiot my name's not ACTUALLY Sherlock it's Rowan!!!!

haha nah i knew that - i'm just saying there's no way you can actually save petrol - if you do it'll cost you in other things

ie

overinflate your tyres will give you great economy... but decreases braking power and makes your wife think you're a bit of a cunt

ROFL - thanks for the coffee all over my keyboard

True - people will try all sorts of stuff to save a few $, like people who drive 4 suburbs to a servo because their petrol is 0.5c cheaper than the servo down the road.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
