Sounds good, see you there

Quick update before WTAC.

I've rebuilt my front calipers, finished the rear firewall, and done a few other general maintenance things on the checklist. I also fitted up the new larger Fenix oil cooler that I've had sitting around for a while and remounted in front of the radiator as I wasn't really happy with the positioning after the FMIC piping forcing it to be moved back. Hoping this helps with oil temps on track.

Car is pretty much as ready as it's going to be for WTAC. I'm trekking down tomorrow morning to get setup and hopefully get the car scrutineered ready for Friday if possible. If anyone is there swing by the Nulon garage and say hi, I'll be hard parking it with the other Nulon guys

Pics and vids to follow after the rush that is WTAC ^_^

Well, that's all finished rather quickly.

Will put some more info up later with a more detailed post, but in short, three days of abuse and absolutely zero issues. Set a new PB for GP Circuit at WTAC, finishing with a 1:45.9. Then on the Sunday I set a new PB for South Circuit with a 1:05.28. Vids of both below:

Ah the joys of street tyres and having to chase the grip. Tops vids

[Leroy Peterson]

was good to see your car in person, and cutting lots of laps as well

[Dale FZ1]

Setting new PB on both circuits on consecutive days is a good effort.

No breakages a great indicator of strength.

Waiting for the full report on these events.

I've probably asked you this before Tim but where did you get the front lip from?

Combination of Bunnings, Clark Rubber and a sign writing shop

 

Also, thanks for the photo Leroy

I got to meet Tim and the team at WTAC... awesome team effort, love it!

Car doesnt' dose though LOL

[timmy_89]

Well I'm being terrible with updates in this. Hopefully I'll get a chance to sit down around the Christmas break. Anyway, for those that didn't know, I made a very late entry in to Challenge Bathurst. I has originally planned to enter early on, but was told that it had been filled so never followed up. A week before entries closed, a newsletter was released saying there were still spots, so then the run-a-round began to try and get an entry sorted haha.

Being a local now, and having done so many hill climb and supersprint events on the track, I have been holding out to race around the full circuit for a long time. Funds were tight, especially with the need to purchase some new racing apparel to meet the standards of this being a state level event, but I knew I had to make it happen.

The event was awesome. So good to finally drive the full track in anger!!!

I managed to set a PB lap time of 2:37.2 - I'll be honest, I didn't really care about the Modern Regularity side of things, I just wanted to see how fast I could go. I'm pretty sure this was the case with about 95% of the field haha. My fastest lap time was a bittersweet one though, as you'll see in the video. Still running AD08R's, I was often struggling for grip after only 1 or 2 laps with the heat. Unfortunately I locked up coming in to the chase after a flying lap, but even with this, I still managed to better my previous PB by 0.1s!! Knowing this, I definitely think the car is capable of a 2:35 with a clean lap, just a matter of piecing it together.

And here is footage of a cleaner lap - my fastest on the Saturday which was a 2:37.3

Unfortunately after setting the 2:37.2, I blew a turbo gasket - yet again, so was unable to better my time. I did set a 2:37.4 with the blown gasket so that was definitely a good sign.

I think this will be my last event for the year, so I will take the next couple of months to go over things on the car and make some plans for the next year.

[Dale FZ1]

Great effort there Tim!

Rubber and rear bias look to have held you back but you should be happy with that.

[timmy_89]

Ok guys, I have to apologise, I kinda let this one slip...lol.

I'm going to try and bring this back up to date tonight/tomorrow so will be making multiple posts so as to break up the posting process. If you follow my Facebook page (Tim Burt Motorsport) you probably have a fairly good idea on what's been happening anyway, but for those who aren't you will soon be in the know haha.

[timmy_89]

So finishing up from my last post at Challenge Bathurst last year, that was my last event for the year. I replaced the turbo gasket (yet again) and got the manifold and turbo housing faces machined to rule out any warpage. The car then sat in the garage for the next month. Couple of pics from the event:

I finished up the year managing to take home a trophy from the local Bathurst Light Car Club (Peter Janson Speed Champion trophy) which was for my results in non-local speed/tarmac events which was pretty cool.

Start 2017.

By the time the new year came around, I'd been quite busy with non-car related things in life, but had been planning what I would do through the year. In the process of saving some coin, Nulon asked me to bring the car down to Sydney for Round 1 of Nulon Nationals to put the car on display seeing as I wasn't competing so for the day I joined the stance life 

[timmy_89]

Fast forward a few months of saving and the car was dropped off at Redsun Motorsport & Mechanical for some much needed love and upgrades.

As is always the case, things escalated in the build whilst the car was there. What started as "let's chuck some bigger bolt-ons on the car", turned in to "let's build the head and see how much we can push the bottom end". I partnered up with Andy from Adaptronic whilst he was developing their new plug-in Modular ECU for R34 GTT as well which was exciting. I enjoyed using the Nistune but it did have its limits. The new Adaptronic ECU would rid us of those.

Head was removed to be machined and then built in house.

[timmy_89]

We had planned to have the car ready for Nulon Nationals Round 2, but unfortunately a poorly designed part (from a last minute change) held back completion of the car and I missed the event. Going in I was going to keep the original plenum and just redo piping, but once I was there and we had discussed it I decided to install a Plazmaman plenum.

As it turned out, there was a stock shortage at the time and was not expected to be in stock for about a month, which wasn't going to allow the car to be completed before Nulon Nationals Round 2. Matt had a RB26 plenum on the shelf and we opted to use an adaptor to fit this on the RB25 Neo. Turned out this was a bad decision and required some hefty modifications to the water galleries on the section that fits between the head and the throttle bodies (sorry correct name eludes me). I have photos of this but cannot find them at this minute so will post later if I remember.

Before the car was fully ready to go, I picked it up from Redsun and took it home so I could install a 4 point AGI cage. I was pretty close to the time at WTAC where clubsprint cars required a minimum half cage and figured with some more power on its way it was probably time to do this anyway.

[timmy_89]

Anyway, with the cage installed, I took the car back to Redsun to finish everything off and get the car tuned ready to compete at Aus Time Attack on 4th June.

I was eagerly watching the car being run on the dyno hoping nothing would go wrong after changing so much. Started getting excited when it started producing results over the 300kw mark, at less boost, and with better response. The expense was now starting to feel worthwhile. After checking over the vitals and letting the car cool down, Matt was back at it and after a short time I was ecstatic to see a result of 392.6rwkw. 1kw more than Mr Wootten with his "real" track car  

On this run the boost line blew off the boost controller at about 6500rpm, so there is still a little more left in it. With Aus Time Attack just a couple of days away, and me eager to drive the car, we decided to finish tuning the car on a lower boost setting and just get some kms on the new setup. It was tuned to around 350-360rwkw for Aus Time Attack.
