  1. Yeh good point, still running a shimmed diff. Maybe it just felt like similar track time because there wasn't many wasted laps with traffic or having to do cool down laps to give the brakes a rest.
  2. Cheers man, yeh i forgot to mention what rear camber i wanted but assumed he'd do what he thought was best. I guess he just didn't touch it. There'll be a couple more tweaks ill want done so it'll be back. It was occasionally breaking traction in the rear on some exits but it kinda chirped then gripping up again. May be a 'slick' thing coz they dont really squeal to let you know you're about to break traction like semis do or it may be a little too much rear toe in. Format is excellent though, I'm thinking ill do all 5 next year if i can. Six groups according to previous lap times, grid up on the second straight and take off in pairs, drag to the first corner (or if you're smart, line up next to a mate and one takes off 3 seconds later) for 1 standing, three flying. Four sessions for points and there was time for a 5th so it was as much track time as the test and tune but apparently the numbers were usually higher.
  3. Alignment done just in time to load up for Winton Weather was threatening showers and storms possible all day but we had a pretty good day. In the top class Modified, turbo awd because of the slicks, the BP sprint runs a standing lap and three flyers and scored by adding you best of each for the day. Last time out here was a year ago on old semis and a heap of camber and I managed a 1:39. After the first session I was stoked to be P1 overall with a 1:33.4 flyer and a 1:40 standing. Obviously knew the car had a bunch more in it, taking it relatively easy on the first lap in particular. The car was basically faultless all day which was good because I managed to forget basically all my tools. I focused and learning how to get the best out of the new set up which I couldn’t fully master. If I remember some tool for the final sprint of the season next week I might check and play with tyre pressures also. I finished the day with a 1:32.0 flyer and managed to hook up and fluke a 1:36 standing lap which I’m stoked with. It was enough for 3rd overall behind two fellow club members in a 32gtr and SR20 Datsun. I’ll definitely be doing more of those days next year. The new wheels and tyres with a bigger overall diameter means some of the gear changes for this track have changed for my rig. Most notably, I wasn’t getting into 5th on the main straight but I think the engine may be slightly down on power from the last one. I’ll have to get it in for a tune in the off season and get a touch up. Despite being over 7 seconds quicker, coming onto the straight carrying a lot more speed and breaking deeper, the top speed was only 8km/h faster than last year.
  4. Got the slicks mounted up Shorter lcas made and fitted And a few other little jobs ticked off, replaced wheel bearing, tie rod boot. In for a full alignment Thursday and then BP sprint at Winton on Sunday
  5. New diff and fuel system were fine but alternator has died on me. Picked up some slicks ready to mount on my now vacant 18x10s I’ve ordered a new alternator and a flat Nardi style steering wheel so I can use a quick release adaptor. I’ll put my old one in my dirt track 92’ corolla. Next big purchase will have to be a roll cage, hopefully in the next month. I want to stick with bolt in because I’m convinced I’m gonna put this thing in a wall at some point, just need to do some homework. Next race is 6 weeks away, enough time to make some new lca’s, get a wheel alignment and mount up the slicks
  6. Pulled the stock tank out of the dirty3, not a fun or easy job. Needed a farm hoist to make the job easier. Tank internals were all f**ked up and bent out of place which meant we were never gonna get the last 20+ litres out of the tank. Explains the fuel surge issues we were having. Cut out the spare wheel well bracket an took to it with a sledge hammer to mount the cell and central and far forward as possible. Positioned the cell sump to the rear so fuel would run towards the outlet under heavy acceleration. Plumbed up the fuel lines and wired up the pumps and she's about ready to go again this weekend. With the 25kg+ reduction in tank weight and the unusable fuel we were lugging around this should shave 40 - 50kgs. I'll take it for a run at a fun day at Winton on Saturday to test the fuel system and diff. I'll just be running the fed 595's that came with the weds. I'll finish off what's left of them off at another drift day at Winton skid pan that the car club is running early October then I'll grab some slicks and see how it stacks up with the big boys.
  7. A few changes and a few purchases. Got a set of 18x10 weds sa70's real cheap from a local sau memeber. Wanted to get rims this size as a club member has a virtually unlimited supply of cheap slicks that most of those ahead of me are running. We've done the typical rough as guts door cards and rear fire wall hole filling with thin alloy. Rattlecanned the parcel tray black on Friday to get rid of the glare for a weekend of racing. I will dry ice the sound deadening eventually and paint it better. Toying with a xr8 powerbulge for a future top mount blower that may never happen and had it vinyl wrapped. The club ran a lap dash at Wilby on Saturday, camped the night at the local and ran a drift day there on the Sunday. The car ran faultlessly for grip, bar a little fuel surge issue in the last session when the fuel level was down under 1/4. Threw 20l at it as I'd qualified p7 for the top 10 shootout. Wasn't my cleanest lap as it just started to rain in my warm up but it got heavier for some so it was enough for p2 with a pb of 35.55 still with clapped out old semis. Big night on the turps and a trailer skid later, my first attempt at a drift day on a very narrow track. Was a heap of fun and spent a lot of time off track before I blew a hole in the diff. I was having too much fun to realise that I was single pegging my last lap for the weekend. I haven't pulled it down yet to investigate but happy with how the car ran across the weekend. Not wanting it to be out of action for long, it's back out to the farm for a freshly shimmed diff, a shorter set of modified lcas, fuel cell and a few other small jobs, should be ready to race again as soon as next week.
  8. Thanks John, in the essence of bush mechanic style build, our temp solution is a giant brake light in front of my eyes wired for oil pressure warning... can i ask what clutch master setup you used? we're contemplating a change
  9. Made the lap dash with most jobs complete, no time for a tune though. Car ran really well, pushed it 80% in the first session an it felt much more powerful, came in an had lowered my pb by 1.5s and into the sub 1 min club with a 59.3. After seeing that I was itching to push it to 100% in the second session which ended with a 58.2 an temporarily into the top 10. The old tires were starting to go away a bit but thought I'd give them one last shot at bettering the time in the third session but soon discovered I have stripped a half shaft which was the end of the day for us. Pumped with the time but still haven't had a full days racing yet this year. Bought another diff an swapped out the half shaft. Today had another crack at motorkhana and khanacross which was a blast. Car ran solid despite a few small niggles but just happen to drive on the trailer at the end of the day without a new issue to fix. I left the semis on the front an just ran scrappies on the back, noticed the front left had delaminated so it's well and truely f**ked. I'm having a hard time convincing my old man that -7 is too much neg camber. He somehow thinks that we wouldn't scrub tires and would run better times with the camber as is but get rid of the front toe out [emoji36]
  10. jeez i really want to drive this thing
  11. Discovered a few demons whilst dismantling the engines today. When the double row timing chain was fitted, the oil pump spacer was installed backwards which we can only assume had a missive effect on oil pressure/flow This is how it was sitting, restricting the oil flow by nearly 50% and if you look closely, spitting oil straight back into the sump. The cam came out looking ok so we jammed that into the new block. Never knew the specs of the cam so I'll have to do some homework and decipher the digits There was a fair difference in the sump baffling between the two and the Monaro sump looks like it'll do a much better job. It has tighter fitting baffle all around, it tapers down to the oil pick up and it's got a few fins to help point it all in. Original And new We didn't get it done today but we'll swap the dual valve springs across to the new setup The engine mounts needed to be swapped as they're different an I managed to strip a thread doing so. Quick helicoil an all good. Got a new starter motor on order which should come in the week but with 2 weeks till round 3 and zero free time I don't think we'll make it.
