thats great new man...

just goes to show how important a good tuner is...
you could have all "the shit" in terms of parts, but then a shit tune and you'll go no where... add a good tune into the mix and everything changes.. :)

Well with changing all the weight distribution by stripping out the car, i ended up spending about 4 hours yesterday with Cam setting a base level Ride Height on her.

I found that under heavy braking the back of the car wanted to be the front of the car - badly :(

But i think that Cam and I have worked out a good base set up to start with and work from.

She is booked in tomorrow to have my alignment done to combat me stuffing with the heights.

Then off to QR on Thursday to work out how she is going to perform and also then Gatton on Saturday and Sunday. After that i will have some more data to continue to tweak the setup.

Well....

All i can say is that she is not going so well :(

The suspension needs a lot of work on it, and i think that i am going to strip it all out and have them all checked and set correctly, recalculate all the spring rates required and then do some track tuning with Nick.

I ran QR on thursday and was 2 seconds slower, and then also ran Gatton Street Sprints on Saturday and Sunday and the car just will not turn in until you do stupid things. not very safe or enjoyable to drive at the moment.

I also blew an EDFC motor and controller on Thursday, but managed to get new ones installed by 3pm on the Friday ready for Gatton

Manage to not crash at Gatton, but did not get in the top 10. But with the way that it was handling I was happy.

Since Gatton I managed to do a QR event and was still about .5 seconds off my PB which was definitely starting to piss me off.

I then attended a Lakeside day, which I have to admit I enjoyed a little too much. Although the handling was all over the place I managed to start the day at a 76sec best lap in the first session. My aim was to get a sub 64sec lap with the car as it was. I managed to get that by the 4th session, and then continued to better it in the 5th, 6th and 7th session finally managing a 61.1.

I have broken another set of brakes in there somewhere…. Cracked the shit out of the rotors and the car has been off the road for about 8 weeks.

While it was off the road, I have had the car setup correctly (finally) so I think that most of my handling issues should be sorted. It has been completely corner weighted and managed to fix the 200KG difference between sides and it is now reduced it to 16kg difference. Also put in an anti lift kit, more heavy duty bushes, heavy duty rack mounts and a 24mm sway bar on the rear.

I have my new rotors sitting in the garage now (although I am still waiting for my new floating hats to come out of Japan), along with a full rear rotor upgrade too . Nick will be installing them on Wednesday and I will have them redone when my new hats turn up.

I raced on dirt 2 weeks ago (with cracked brakes) so I treated it as a shake down with the new suspension. It is a lot tighter in the rear, but after some tweaking managed to get it feeling ok. I am really looking forward to getting it on tarmac which is now really what it is set up for.

I have a TRE on the 10th, which I will be using as another shake down. Then QR on the 15th and then Noosa Hill Climb on the 17th and 18th.

I am really hoping to get into the 58’s on the 15th!!!

copy and pasted some updates from the WRX forum :)

28th August update

Well with suspension doing well apart from the unicorn i have in the rear. i have turned my attention to getting a little more corner speed as i am not keen to touch the engine any time soon.

As such I spent about 4 weeks researching and learning as much as i would about aerodynamics. My attention started to focus on this after going down to super lap and seeing the Japanese cars with heaps of aero.

I looked at doing the cheap thing and building my own splitters and diffusers, but finally came to the opinion that i should just pay the money and use a product that has been tested and has someone with way more brains then me design it.

So I ended up picking up some Canards, an APR front splitter and a HKS rear diffuser.

I installed the Canards about 2 weeks ago, and have not really been able to take the car anywhere. But when i was at carlovers washing it the water did behave as i expected as it can out of the high pressure hose pointing at them.

Then this weekend i installed the rear HKS Diffuser:

I am hoping to have the front splitter here in time to install it before Pittsworth, but i am not too sure.

On another note, i am having some major issues with my engine which i am trying to work out what it is from???? my Advanced Multiplier dies every time i drive the car in anger. If i reset it on the road it is then fine again till i get it back to a track and get into it??? I have used a few different tanks of fuel and it is the same. I am not too sure if it is knock, excess heat or what? I have been trying to call Michael but he has not got back to me as yet. Fingers crossed.

Because of this, i am tossing up whether i should sell my delta dash and get a full logging dash???

anyone want a delta dash?

Now further to my brake issues, i did crack another set of SRC-Pros, but this time i finally have a replacement for them.

At this stage, I think that they are the first set here in Oz and they sure look the part.

I have not had them out anywhere to test them yet (as Time Attack on monday the track was wet so there was no way to get them hot)

They are called the Project Mu SRC-GT and are a fully floating 2 piece rotor which were released in Japan in March this year.

Installed :)

So next things on the list will be further investigation into a dash, possibility of aerocatch's, moving the battery into the cabin and wiring in an internal and external kill switch, Installation of a window net (catches, net and switches so i can look at running top gear next year), new wheel nuts and threads, getting my race rims painted black (as i am too lazy to wash them)


ist September update


ok .... got something in the post today from APR in the us :)

not too sure if it is going to be ready to run this weekend at pittsworth as there is actually i bit of weight in it and i am not too sure that the bar will hold the load when the car is moving.

also i need to make some type of bracket in the middle at the back as it is not rigid enough.

here is the pics do far (it still has chalk marks on the carbon, but it will clean up nice).

I might also have to have the entire car lowered to get the most out of it too :(

15th September update

Black rims :)

Shitty iPhone photos but you get the idea

Todays update

Well she made her way back up to Toowoomba yesterday after having replaced the rear O2 sensor. The old one was reading a maximum of 0.03 volts, compared to the new one that now reads up to 0.96 volts – which is what they are meant to read up to.

Michael spent time working on the timing an boost mainly. The factory ECU is now learning and playing with at least 13 degrees of timing, which is great news, as there does not seem to be anything wrong. The boost curve was the main thing, and you almost could not draw a straighter line with a ruler :)

It rolls up to 18psi just after 3700rpm and then holds it dead flat until 6500rpm when it runs out of puff and slips back to 16psi.

She is not running quite as hard as she was before the sensor failure, but it is that close that I am putting it down to climatic/tyre pressure/ anything. I am happy that is it back to normal.

The new normal is 205.1kw with 5800N of torque. Not too bad for a standard engine and turbo set up.

Image Image


We compared a dyno graph of mine and another MY05 with headers on it, and I think that will be my next thing, the power and torque came on a lot stronger and carried it higher the entire way through the rev range and finished up with the same peak power. But having it there in the low and mid range should be a good thing on the track.

Quick update on my standings for the year. I have managed to creep back in to first for street class at Time Attack which I am happy with as I really want to try to defend my 1st place. It is going to be close though, as the GTR is a complete weapon and I am sure that he will pip me back in the last round. Also, 81TTn put on a good show at this year’s Iron Man managing to take home the clubman and the outright trophy :) also managed to set two PBs over the weekend too, a 61.7 on the clubman and a 46.2 on a greasy Mount Cotton hill climb.

Thanks Graham! It has been a very long and expensive build and it is still not running 100%.

But I am really happy with the way that it has turned out, but to be honest when you jam 295 rubber any car they start to look sexy :)
