I watched this on 60mins and it looks freaking AWESOME.

I hope to buy a R34 GTR and max it out as the be all and end all experience that this world has to offer.

Can you please tell me what tires would be best suited to undertake a event of this magnitude?

Also does the salt damage any of the car or engine components like the air filter?

Thanks heaps for your info I am very much looking forward to completing this dream.

tyres for speeds up to 150 mph ( 240 kmh ) HR rated tyres

" " " " 200 mph ( 320 kmh ) VR or ZR rated tyres

most good quality radials are at least HR rated these days .

you can download the rule book for free at www.dlra.org.au

the salt hasnt done my car any damage yet . i,ve had it there 3 times . just clean it with air and water underneath . also because i drive it there i believe most of the salt gets shaken off on the road out of there ( about 150 kms of gravel and corrugations ) .

i dont use an air filter at all , just have an 80 mm intake sticking out the front below the front bumper . at high speeds it s allmost like having a low pressure supercharger ( gave me an extra 6 mph the first time i used it )

2006 EVENT ON 6-10 MARCH

I,m going to run the red wagon again .

Have done a few mods , twin throttle body set up , 6 ltr surge tank and extra fuel pump , adjustable cam gear on exhaust cam and a bit more tuning . Hopefully will get the 150 mph ( 240 kmh ) i,m after .

nice

that twin throttle setup looks pretty mean ass

huge surge tank(? - i dont really no how big they get but it seems pretty big!)

the adjustable cam gear would help

good luck anyway

yes couple of reasons for such a huge surge tank .

1/ i.m at full throttle for up to 8 kms and around 5 km at max speed .

2/ only need a relatively small lift pump running at low pressure ( bosch 040 ) in the tank , and allows me to keep the stock fuel lines to the front .

from the surge tank i,m using a bosch 909 inline pump for the high pressure side of the fuel system .

heres an earlier pic of when i 1st put 2 x tb set up on

damn thats a pretty hard out fuel system. i wonder how much of mine i will have to upgrade when i put the rb30 in. iv got a rb25de fuel pump for the mo.

good luck dude. are you sure you have good enough gearing to get to 240kph?

Am using rb25de 5 spd that has the taller ( . 76 ) 5th gear , 3.7 diff . This setup gives me an overall ratio of 2.81 Also i use the tallest tyres i can find that have a speed rating of 240 kmh ( 205-70 x 14 ) . 6000 rpm in 5th = 158 mph ( 252 kmh ) . Also taking 2 smaller dia sets of tyres for the rear to gear it down if i need too .

dading

i finally worked out why a surge tank is often used in performance cars

2 pumps - 1 low pressure one because the height diff between fuel level and surge tank is very small (ie small head heigt)

1 high volume one to have high pressurised fuel system as it enters engine

hahahaha i get it now

but.. it is important that the small pump can pump more than or equal to the amount of fuel that the high pressure one is sucking out

and dont worry...im talking to myself (kinda - i often 'talk to myself' by talking out aloud - wierd i no but thats just me :domokun: )

Went to Lake Gairdner salt lake and raced the wagon . When i got there lake had water on most of it . We couldnt race until tuesday afternoon . Wind had blown most of water away . we ran on a shortened course and it was a bit muchy in places .

I did a best of 141 . 18 mph . that was on my 1st run and on the short course . After that on the Thurs and Fri i did 2 more runs . For the secound run i increased fuel 10 % fitted new plugs and fitted cold air intake . At 5550 rpm in 5th it started missing , fuel starvation prob . For the last run i connected up the 6 ltr surge tank with extra bosch pump and had same prob . mmmm .

I did break my class record by 4 mph , and considering the condition of the track , and the fact that not many records were broken this year , I spose i should be pleased . just got to sort that fuel prob out .

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
