Ya the weather can't get helped glare.gif

Good to see everyone. See those at Winton next weekend then DECA and WRX Sandown after that.

The supra was sporting a sequential gearbox and was seriously moving, also a V8 supercar (spec'd) that got pinged for noise after 2 laps.

We kept it on the black stuff, but one of the GM boys didn't and the armco at turn 3-4 were rearrange a little.

Was good to be back out there, even if after my first exploratory session I was pinged for noise. So didnt even get to put a lap in :( I did go out in the wet in the afternoon but was forced to shift at 3,400rpm due to noise :( But got to put som eheat cycles into the new brakes

Oh well. I had no idea where the correct braking points were and was just trying to bed the brakes. So much harder to pick the braking points compared to Winton. Once they were up to temp I put in two laps to really jump hard on the brakes to get them nice and hot then backed off to let everything cool down.

Was shocked that I did a 1:25 flat. The old girl seems to drive about the same despite the dyno showing I have lost a fair wack of mid range. I reckon if i didnt get pinged for noise it would have been fun chasing the Supra :)

In all it was a trying day, picked up a puncture from a screw in the carpark, Radcam farked up again and didnt get a 90% tilt at a lap....but I think the brakes passed their test and I got some seat time which is drastically needed.

Well done Bris, looks like the old girl has still got it in her. Mate I'd love to see what this thing would do with a decent wheel alignment, quiter exhaust (to be able to go flat out) and more seat time.

Third fastest overall, gotta be happy with that.

Look forward to see how you go next Sunday at Winton...

Apparently the Supra is currently a couple of hundred HP down on what it used to be, I have seen it about the traps a few times and thought at a sprint earlier this year that it was not as quick as I remembered. Still no slouch!

I was happy enough with a 1.31 in my coupe given it is effectively the first time I have run it there (Got about ten laps the only other time, stuck behind some nong in a Gemini who was like a snail through the corners and dead set fast in a straight line, and then it rained so hard that they stopped the day) I could certainly have gone a few seconds quicker with a bit more bravery under brakes at the end of the two straights.

I can say that a HR31 on semis is not a lot of fun without power steering, the belt failed in the first wet session so it was armstrong time! It was still managable (Just) so we kept running. But with the rain it made hard work of a twitchy car, 200 odd RWKW at 5600 rpm and seriously snappy onto boost in the rain is sort of attention focussing. Second was virtually unusable, third was inclined to break away at about 4500 rpm and it broke away a couple of times in fouth. Would have been great fun with the PS pump still doing it's thing.

Yep, that would be the one, it used to be an absolute rocket in a straight line, now it is just very very fast. I was told yesterday that it is nearly 200KW down on what it used to have! I have been told in the past that it had around 500KW and given the straight line stomp it had first time I saw it, I would think that was possible!

Interesting way they unload it. It arrives on the back of a flatbed rigid truck parked on top of a steel lifting frame. They hook the truck mounted crane to the frame, hoist the whole lot on to the ground next to the truck and then push the car off on the flat. It would be nice to have money to have toys like that.

      Why am I hitting a power wall with my stroked RB25?

      By Dose Pipe Sutututu · Posted

      Given you're running a 2.8 and my 2.5 is not really like for like, I suspect there could be a bit more timing you could give it. What is the kW yield per degree you're putting through it? Here's my E85 map to give you an idea, where it was I could still get another 3~4kW per degree thrown at it.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      It turns out that Setrab make a fan specifically for the oil cooler which is great and I've installed it with minimal swearing. I removed my 2x 12in push fans from the front of my aircon condenser and wired them into this. My main thermo fans kick on when I use the aircon anyway and would effectively already be working as puller fans through the condensor which is infront of the rad. The push fans (understandably) didn't really do much in the config they were previously in so now they're out. Now we're on to the "Oil fan doesn't really do much either!". Yes I'll duct it next if it does nothing in heavy use which it shouldn't. But hey, the object exists and fits great and is cool. Let me have this. The car is still in the "do my fittings leak oil now? do my wheels actually rub?" phase. I did a spirited drive on them and didn't hear or feel anything. Then I got back home and noticed there were grind marks on the inside of the rims, though I couldn't see where they were touching I got out the grinder and attacked the suspects. Note: I do not know how to use a grinder. Then I realised I had dragged my new rims across my concrete driveway before I did this drive. I didn't think I had damage at that time when I briefly looked...... but remembered this occurred after I did all the angle grinding. The grinding on the wheels in some very specific spots. It's not around the whole rim for example, which lines up with dragging it across concrete more than hitting a suspension component for even 1 full rotation. So everything is currently painted and taped up and I need to test it some more to see if it really IS rubbing, but from inside the car it doesn't feel like it is. In other news I attempted to do a before and after comparison of the heads/cam upgrade thing. Dynos lie, everything is in different measurements. Here is the data from the sandown back straight. Car go faster than before. Vroom vroom.

      Here's my base ignition. +3 correction to redline when shooting water/meth which is always on. Looking at my old ignition table, I should be able to add 1-2 degree's next time I'm on the dyno.  Let me know your thoughts.

      Given what I know now - same haha, but this was 12 years ago with second hand 740cc Nismo injectors in my S15 daily, I was too busy hunting elsewhere for the issue to even look at the injectors, running through some cleaner was a happy coincidence haha

      Not a terrible idea. But if I ever had concerns that my injectors were sufficiently dirty to be causing me a problem, they would be out of the engine and onto the actual injector cleaner/testing bench.
