Ok, I started the same sort of thread on the SDU web site but, lets face it this forum is MUCH better. OBJECTIVE : Do mid 13's(possibly lower) all day with the standard ecu, intercooler and turbo re

Just my 0.02c re: BOV discussion. I think that it's a big mistake on anyone's part to say that externally venting BOV's, "make your car slower" "are just a wank" "aren't as good as standard" "are

i got a 13.981 at calder last night... could have probably done better, but happy for a first real strip run. Set my 235/45 tyres to 16psi and I have pineapples on the back - seem to have less traction probs than some of the other gts-t boys who also ran.

What mods do you have??

a few :P its not really "stockish" though as the thread indicates...ah well..

S-AFC, cold air intake, dump pipe, hi-flow CAT, HKS Super Dragger II cat-back, blitz pod, HKS FMIC, ProfecB EBC, heavy duty clutch, pineapples, zeal coilovers, falken 235/45R17.. stock ECU, stock Turbo @ 13psi

i think some heat buildup and trying a bit too hard could have effected my later runs.. i'm gonna wrap some of my piping soonish to maybe fix that for next time.

thanx :( other runs were around mid-14 at higher MPH (~100).

Its all in the takeoff, which i'm sure you know, but its definitely what I found out on friday. The difference between a 14 sec run and a 13 second run is all in a good takeoff.

Easier just to just post the timesheet with the 60', etc.

If I can get that a bit lower (which I think I can next time), I think I may be able to get about a 13.6 or something with a perfect launch and my current mods. I'll be happy with that until I one day I upgrade the turbo, ecu and maybe a couple of other things which should push me into the 12's. 12's for a daily driver that is RWD would be pretty nice I reckon :(

anyway, enough about me.. back to general discussion

yeah.. other runs were worse launches, but better shifting after that, resulting in higher top speed of around 101mph

If i can pull both off in the one run i'll get somewhere around the mid-13 i think as well.. tyre pressure could have been a bit low @ 16psi for street tyres??

I ran 14.370 @ 98.79, 60' 2.407 with a pod (no cai) and a 3" cat back zorst. I believe that 60' time could come down a few tenths with a bit of practice (I only had 3 runs on the day).

I just dont get it. predator666 you've got some decent mods I'm guessing they'd be around $2k rrp? Surely to goodness your $2k mods are more than 0.3sec better than my $400 mods? It looks like you can launch it better than I can also.

A question for all: How much did you spend (and on what), and what affect did it have on your times???

Most of the stuff came on my car.. but if u added them up prolly $6000-$7000 or so :P read back a page for the full list. 0.3 is a reasonable difference.. and 1 second is a massive difference in terms of what you need to do to your car most of the time.

That run i felt like a pretty perfect launch, and i took it a lot more easy on the gear changes afterwards. Maybe i backed off right at the end? (no idea). Anyway, its all in the timesheet up above, i'm no expert, and i don't remember every single detail! I only had about 4 runs.. next time i go, i'll hopefully have some more runs, and hopefully get a better time as a result of the practise.

Waming up your tyres with a burnout is good for show, but not really going to help you on street tyres.

I ran at eastern creek again last night and got a 13.102 @ 108.46 mph, killing my old time of 13.7 @ 105. I was much happier. My 60ft this time was much better, of 2.114 over 2.365.

I walked away grinning from ear to ear (I was hoping for a 13.4) :) :) .

I have standard internals, injectors and fuel pump. I am running a custom plenum, XF trottle body, FMIC, EMS management, high flowed turbo (metal wheels, no bb centre), running 17psi boost, exhaust, etc.. The tyres are 255/35R18 Fulda street tyres let down to 20psi.

Here is a pic of my engine bay,

They are close but still handling it. We have looked at them closely on the Dyno, but they are still upto the task at the moment. I am looking at a bigger turbo at the moment, so I will have to do something about the fuel system soon.

      Are you an oil nerd?

      By joshuaho96 · Posted

      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.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      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.
