Was in Woolies readin the latest Motor mag and they had a review of the aformentioned cars. Of course the first thing I flip to is the performance data. What stunned me most is these cars are pulling 109/110mph traps? How can that be possible? You need ~200rwkw in an S15 or a tad more in a R33 to do so. And these cars have substantially less power and more weight. The power to weight ratios are no better than a stock R33/S15.

Anyone smell BS?

are you saure they are saying that they are hitting that speed buy the end of the 1/4 mile, or do they just have the times it takes for them to hit those speeds. as any info i can find on the xr5t says it takes over 16 seconds to hit 100mph, which would put it well past 400m.

i have a quite a few motor mags and they don't usually do 1/4 mile runs at the drag strips. they usually bolt a big thing to the side of the car that has a wheel that runs on the ground.

most of the tests i have seen (infact all of them) have the times it takes for the car to get up to about 160-170kmh, even though they might do the 1/4 at 155kmh.

but either way i'm going to go to the newsagent tomorrow and check it out.

Shit !, read about the MAZDA 3 MPS and watch the fifth gear review on it....thats things got a SHiT Load of tourqe....too much i will say.....my stock r33 will be blown to bits if that 390NM got stuck in to me....

xr5 has tad over 300nm of torque from 1800rpm onwards, as a result the 6 speed has tripple synchros first 2nd and 3rd gear, plus a proportioning valve in the hydro clutch (clutch in you cant rev dump) :P. nifty lil car, ive driven them, not to sure bout the holden however.

i work for ford, and have had a xr5 in and been in one when being driven, nothing compared to my r33 gtst with 205rwkw :P even on 7psi my skyline feels faster. These cars do hit high speeds, but no way are they 13 second cars... No way in hell. If the GT-P is a 14.0 second car or thereabouts and the typhoon is 13s or so, the xr5 is nowhere near as fast as either of these cars.

i dont have 205rwkw..would't mind though.......but bugger....scary thing is my GF likes that car and she likes the Mazda.....

so all of these are FWD right....do there have trickly hitech LSD like honda type r....otherwise how on earth do you put the power down.....

ok, well i have the mag. and yes they do have the figures as-

astra 0-100= 5.29 seconds and 0-400m= 13.42 @ 176.8kmh

xr5t 0-100=5.41 seconds and 0-400m= 13.52 @ 174.9kmh....

however if you read through the article it says the astra does 0-100 in6.7 and the xr5t in 7.5 and across the 1/4 mile are 14.75 for the astra and 15.38 for the xr5t. this got me thinking that someone had cocked up. so i flicked through for another 6 or 7 pages and come across a comparison of the bmw z4 m roadster and the mercedes-benz slk55, and do you know what? guess what the performance times for they are. thats right, bmw z4 0-100= 5.29 seconds and 0-400m= 13.42 @ 176.8kmh and mercedes-benz 0-100=5.41 seconds and 0-400m= 13.52 @ 174.9kmh

so there we have it. they cocked up after all.

    • You're not wrong but 5W30 at 100C is like 10 cSt vs 25 cSt for 10W60. If we think in terms of viscosity margin 10W60 will probably still be ok at 130C but 5W30 is probably too little. It's absolutely shocking how hot the oil gets in something like a stock FL5 from only ~3 minutes of use on the Nordschleife. I would not risk taking a car like that to anything remotely intense without a ton of work done for cooling. Heat shielding on the manifold/turbo/downpipe, oil coolers, etc. 
    • I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet. 
    • Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.
    • Oops... I meant to include the connector  view... BR/W - power from fuse L/W - motor negative to fan control amp (and off to HVAC pin19) OR/B - PWM signal (from HVAC pin20) B --  ground  
    • Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.
