White 35 and I have just returned from the Twilight Track Day put on by the circuit club. What a great event. 6 x 20 minute sessions after work including night driving. We were both using stock wheels and rather used road tyres.

I managed to crank out a 1:46:04 and White 35 did a 1:46:68. Not bad for stock wheels and tyres. Cant wait to set some times with slicks.

Can highly recommend this format to anyone looking for a midweek speed fix.

It was good to meet you guys last night also.

Would have preferred to have been at the twighlight track session however the Drags were interesting and different. Ran a consistent 11.9 for the 1/4.

12.03 for the first run

then 11.92, 11.94, 11.93. (Terminal speeds were also consistent at 194km/h (121mph), 193.8km/h on the Performance Box)

Consistent runs, but the start was a little ordinary with wheel spin due to the water they were putting down, the car could only manage a 0 - 100 in 4.1, where as the best I have recorded is 3.8.

09GTR ran the Dunlops and I ran the Bridgestones - both of them absolutely fried...

We are both moving to Volk RE30's and Hoosier R6 slicks in the next month.

Both have AP rotors slotted 09, J Hook on mine and carbotek 12's.

Do you have harnesses Duncan? or a Race seat? i was being thrown around the car in the standard seats...

Jeff could to meet you to dude - we all gotta hook up for the next EC day - i'll email you the stuff we talked about at the servo. Gotta get those quarter mile times down to low 11's...

I was expecting a mid 11, basically 11.6 or there abouts as a stock car, but the launch just not happening.

I look forward to catching up with you guys also and starting on these mods.

Gibbo, it was good to meet you albeit briefly. I did an 11.7 stock. The difference will definitely be the launch. You really do have to "sidestep" the brake as the revs start to slow towards 3300rpm (while boost is still building). To get 3300 rpm I find I have to stomp on the loud pedal as if it were a cockroach heading for my gym bag! I also found that my car got quicker as the night got longer for three reasons: 1)temperatures got lower 2)fuel load got lighter 3) track got grippier.

In fact I've got to the stage on the strip where I know more or less what my time will be based on the launch alone. If you hear a small chirp of the tyres as you release the brake, you're on.

I'm going to go back to the drags when the weather gets cooler, put in some octane booster, dial up 20 pounds and have a crack at a mid ten. White 35 is also keen to come, we'll let you know when we are going.

The Twilight was a great night but I do have some questions of White 35. How can a car putting out identical power (detuned for track), with front and rear sway bars, with a driver that weighs 75 pounds with his clothes on, get done by the red version without sway bars and a driver weighing 220 pounds?

I suppose its true....red ones really are faster!

Well done guys, sounds like a lot of fun. Any more feedback on tyres, brakes? what tyres were you running?

I had the Carbotech 12's at the start of the night, but by the end of the night I just had backing plates!! Seriously, coming into turn one well into the 200's, in the dark, mashing the brakes and having a flurry of bright orange sparks flying over my car, wind-tunnel style, might have looked good, but it didnt feel so good! Suffice to say my front rotors are looking a bit soiled!

That said the braking performance of the carbotechs is special. I wouldn't go back to the MX72s for track use.

I am running the standard seat with a harness (just a four point). Looking to fit a race seat soon though.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
