Well thanks to the @#*!ing weather (temp) we haven't had a real shot at tuning on straight ELF LMS :spank:

Yesterday morning Shaun fitted the Apexi actuator & then late in the evening we ran the car up on pump 98. We had to make a number of tuning adjustments due to the new actuator holding boost muuuch better.

The car made just under 260rwkw on the 17psi road map. This is down by ~8rwkw to the previous tuning, but considering it was mid/high 30's & bloody humid inside the dyno cell (@ 9.30pm!) a small drop was to be expected. Inlet temps were in the low/mid 40's due to heat soak from the earlier tuning, which isn't bad considering the ambient temps. The temp/humidity in the dyno room after each run was bloody unbelievable! Good new is the Apexi actuator worked, boost only drops ~1psi now.

We decided to give up for the night as it was still 32'c & humid as hell (@12am) & the neighbours were probably getting a bit pissed at the noise :)

Shaun was back at it by 10am this morning (12feb) & has since ran the car on the 1.3bar road map with ~10L of LMS mixed into the tank. It made just under 290rwkw. Shaun is confident of 285-290rwkw on 19psi reliably, all day everyday, on pump 98 + bit of octane boost. We didn’t bother going all out on the LMS as it’s too hot to bother pushing the package harder. It’d be safe to say 300+rwkw is there for the taking on straight LMS with additional timing & milder temps.

The bottom line is…….. I wanted a ‘safe’ tune considering the expected 40+’c temps on Sat, and that’s exactly what I got.

Here’s a little indication of the potential though……. Whilst doing one of the conservative 17psi tuning runs we accidentally hit 25psi, & although it wasn’t a full power run it made over 7700N of tractive effort & 220rwkw before Shaun backed off @ 100km/h in 4th. On the previous 280rwkw run, in cooler temps, & with more timing, it made 6400N & 180rwkw @ 100km/h in 4th.

I guess there’s nothing stopping me from running 25psi, but I’m happy enough with the current power level on 19psi, so that’ll do for now.

I went down and had a chat with the lads at BoostinOz this arvo. They have around 200 cars entered (I assume since I am no. 191) and it will be bracket racing. I have never done this before so will be very interested to have a go. For those that don't know (I didn't until today):

1. Qualifying all morning/afternoon just for practise and to see what bracket you go into.

2. 5 or 6pm Comp starts, (brackets run: 0-7.999sec, 8.00-9.999 sec, 10.00-11.999sec, 12.00-13.999sec and 14.00 and above (I think this is right).

3. so, say I run around 12.5 during the day (which is my hope) .... then I would be in the 11.999-13.00 bracket.

4. in the comp I "dial in" what time I think I'm gonna run - say 12.5. The bloke I'm up against might run a 13 normally - so he would dial in 13.

5. When we line up he starts 0.5 seconds before me (since that is the discrepancy between our dial-ins) .... then I go and have to chase him down. If I run under a 12.5 I am instantly disqualified. If I don't run under that, but lose to him (even though he got a headstart) then I am also out (unless he runs under his dial-in time). If I chase him down and beat him

(assuming I don't run under my dial-in) I advance to the next round.

Pretty cool, I reckon, the idea of a slower car getting a headstart then having to chase him down.

Can't wait .... hopefully I get paired with someone I know in the later stages fo the comp - assuming I don't get knocked out 1st round :P

Also, after the comp, (time permitting), it will be all-out where you can challenge whoever you want and just race for fun. They are calling it 'grudge wars' hehe. See you guys there - everyone better be coming!!! I am gonna have a shade up, so we can chill in the shade. Will also have a few eskys if people need to cool themselves or some drinks.

Update -

Drove the car home from the w/shop tonight @ ~11pm. Suprisingly it was very cool! The boost controller was tweaked up a tad (25psi) as I still have a pump 98/LMS mix onboard. Now I know that near on 290rwkw (@ 20psi) is nothing special these days, but with another 5psi on board I'm damn sure it was more than 290 on the way home! I had the 540's spinning in 3rd & a stupid grin from ear to ear :P

Andy,

I'll be out there with the Boost Worx crew & I'm sure SAU people will be welcome to mingle in. We've got a couple of marques going up, BBQ/drinks, chairs, basically we'll have the worx :P

The BX team plan is to get a few qualifying passes in earlier before it gets too hot & then kick back a relax until near the end of the 2nd qual session. If we're already happy with the earlier passes then we won't bother doing any late qualifying passes, we'll just hold off till the comp starts.

I've not bracket raced before but was aware of the format & have watched bracket racing many times. In bracket racing Reaction Time is a big factor.

Hey I'm only there to have fun & support the BX team & Autobarn, if I go OK it's a bonus.

Excellent work Matt, I can't wait to go for a belt in her! I went out for a little run tonight and yes it was quite cool, in fact my bleed valve is set at 15psi and it's still running at 195rwkw on Tilbrooks dyno yesterday, but in the cool air tonight I saw it spike up to around 19psi at about 6,000rpm in 2nd. I will have to keep a cloe eye on it at the drags I think. No signs of detonation though which was good. Hope we can line up at some stage on Saturday Matt, it will be a good comparison :P

Dean - have you got Street Rod for PC? I remember playing a really old version many years ago and it was wicked. You could get some really funky old American cars in it too!

Dean,

Yeah hopefully everything goes well mate. I'd really love the temps to be lower so I could run more boost but if it is hot I'll just take it easy (18-19psi).

Andy,

Thank dude. Tonight was completely unexpected re temp! If fact tonight would've been the best to take you for a test run. Yeah a heads up btw us would be interesting. You'll probably nail me on ET. I'd like to think I could get the better TS though.

Dean: yep post the links, I would love to play Street Rod again!! Didn't get the PowerFC :mad: Mark couldn't track one down after all, so I still have the Unichip in - with the bleed valve cos my ProfecB EBC still won't work. Wish I had the Unichip boost module now :( - how did you go with the setup anyhow?

Matt: you will EASILY nail me on ts man .... as always it's just a matter of you getting off the line. Will be a good chase to see if you can catch me in time :)

Yeah I heard the GT 200 was making great numbers the other night then made an unusual noise :( .... obviously they got it fixed/sorted though. I saw Munro's Drift-6 on the rollers this arvo (spent a bit of time in the boot holding the damn thing down) .... 481rwkw is nothing to be sneezed at!!! (and it was AT LEAST 40 degrees at Tilbrooks at the time). I reckon John will get into the 9s with that beast! It sounds absolutely wicked!! I took some video too. :P

    • When you crank your car, and hit it with a timing light, can you see a steady crank timing?
    • Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).    
    • Car is on factory injectors/z32 maf/ q45 throttle body/ z32 ecu with nistune 
    • Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
    • yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
