some video from QR yesterday. Clubman and Sprint Tracks. Clubman is a fun little track, but Sprint still bores me to tears... the new surface is really good - no bumps in the turn 1 braking area and that giant bump in the middle of turn 2 is gone too. 9 tenths faster on Clubman than last time I went there a couple of years ago. Might go back in winter with my lower diff gears in to see if it can go a bit faster.

I did the Mt Cotton hillclimb on the weekend in the 180SX. Bit dissapointed with my times, but it was only my second hillclimb in 5 years and I really struggled to get my head around it all again. Took me till the 6th run of the weekend just to get the first corner right FFS!

Had some front pad knock off, leading to a couple of rear brake lockups in the first downhill braking zone. So I was having to pump the pedal up with the left foot while negotiating the tricky exit of the first loop, nicknamed 'lover's leap' because of its sharp drop off - which was a bit distracting. I was still driving like an old mole through that 1st loop (in both directions) by the end of the weekend, so hopefully there's better times to be had by getting more used to the place again and pushing harder.

Still not sure which gear to use in the hairpin either. I recently changed from the stock 4.083 diff to 4.363 to try and help at Lakeside and QR, but I think it hurts at Mt Cotton. The taller diff would help make 1st gear more useable. Softer spring rates would probably work better at that low speed track too.

I got my best time on the last run of the weekend after a long delay for an oil-down in that first loop by a caterham three cars ahead of me in the queue - I took it so easy through there I couldn't believe I got a decent time! I ran two 48.1's on Sunday, but that's miles away from where I wanted/expected to be. To put it in perspective these are the times I've done in previous cars:

48.3 in a 145rwbhp L20 powered Datsun 1200 on A032R's

46.3 in a 300rwbhp CA18DET Datsun 1200 on nice soft Toyo RA1's

46.2 in my old R32 GTR - never dyno'd but only had Mines ECU, 0.9bar, exhaust and coilovers on puny little 225/50 R16 SR (hard) compound RE55S on stock rims. Would have been a rocket with some nice soft 255s. Shouldn't have sold it!

48.1 in the 270rwbhp 180SX was pretty dissapointing - only a couple of tenths faster than my old two litre Datto! anyway, here's some vid of me driving like an old woman around Mt Cotton:

I think I used the full url from the address bar at the top of the browser. Paste that into the 'insert media' button.

Got the split timing form Mt Cotton. The 180SX loses almost all its time in the first sector compared to my other cars. It matches the GTR in the second sector and there's just a couple of tenths in the third sector which I can probably make up, but that first sector is a bit of a surprise.

I remember the GTR being awesome of the slippery concrete launch pad, and would be better out of the tight first turn with its taller first gear and AWD traction, but 1.6seconds? That's a lot of time! The 1200 was very good off the line in 2nd gear as well with the soft RA1s, and very fast up the hills with 310rwbhp & 950kg.

At least I can see the car isn't completely hopeless around the rest of the track and know what I have to work on next time. Might make some changes to the car too...

went back to QR yesterday to see if the diff change helped. Beat my PB by 4 tenths, so I'm pretty happy with that. Here's a short 2min video - PB on 2nd lap:

My spin at over 200 km/h last Sunday.

bloody hell, not alot of room there! Got away with it unscathed though by the sounds of it?

Was the pedal slightly 'longer' than normal when you got on the brakes there?

Was it you who bought that front bar from a 33 I had?

I can see why you need it... Crazy!!

Yeah I think it was you I bought a front bar from. The GTR style bar with standard indicators. I did a test fit and other things grabbed my attention. Hopefully it will be going on in the next month or so and then I will be looking at an under tray with a small lip.

Not a lot of room at all and got away with it. The tyres are not exactly round at the moment.

Pedal was all good, actually my next run I did was only 0.064 secs slower than my fastest time of the day. So backed it up pretty good.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
