Looks great Pete.

looking great pete! really finishes off the front end!

by the way, i installed the carter 4070 fuel pump - it's fantastic and 100% better than the facet pump. just having some flooding issues in traffic now and was wondering what fuel pressure reg you used?

cheers

I didn't use a reg on the 4070, just straight into the carbs.

Hmm I guess this wouldn't see much traffic ha! Makes sense

[Peter Jones]

Just to be clear is was talking about my old white race car. It's got twin dellortos fed directly by the 4070.

The Kamei car also has a 4070 but it's used to feed the fuel sump. Main pressure to the injectors is by a Bosch 044 submerged in the sump.

See you at the island on Saturday

does this mean you will be "going scene" now and lowering your car to make full effect of that front splitter?

Nope, it's set 3 inches above the deck which is low enough to work and high enough to clear the ripple strips.

First test of this is Phillip Island on Saturday.

Finally upgraded the brakes. This is a Tar.Ox 280mm 6 piston kit. Tarox | High Performance Brakes

As I have MK2 uprights I chose a MK2 kit. Interestingly Tar.Ox has been making these kits for the MK2 since the mid 80s

They clear the Varrstoen wheels fine, the G60 steelies need to be spaced out about 13mm to clear.

These end up being 4kg lighter per side than the Girling 60 calipers.

wow I need me some of those pure brake p@rn

Here' some pics from PI today.

Conditions were poor to start with, improved a little just before the rain set in.

Despite the conditions I managed to break the 2 minute barrier and set a 1:58:9731 lap time.

New brakes are fantastic, exactly what I've been trying to achieve.







The powder coated Bell didn't take the heat cycling too well

The disc looks muddy because I brushed the dust off it with a wet glove.













Went into turn 12 too hot and chucked it sideways down the straight.

Grip was really poor all day long, I just couldn't get the tyres to come up to temp.





Started the day on wet tyres, changed to dry tyres, changed back to wets again. I'm a bit sick of changing wheels!

Got to turn on the heated windscreen and the rain lights.

I was having a hard time with rear grip and disconnected the rear sway bay which helped enormously.



More pics on the website.

First track side video up now.

Session 1 In car footage.

We were first out, the track was cold and traction was poor. Wasn't pushing it for this round as I had to test out the new brakes and bed them in.

Toyo R888 tyres for this session.

Session 2

On the Hoosiers now.

Session 3 - prior to restart

Back on the TOYO R888s now due to incoming rain. Sway bar disconnected for remainder of day.

Session 3 - After re start.

Session 4

[Jarred]

Wow, brakes look great.

How'd the front splitter go Pete? Feel the difference?

Yep, faster down the straight and less prone to lift.

If you're observant you'll see that I had to increase the top speed on the speedo in the videos. Previously I had the gauge read to 180kph, I hit 206 kph on Saturday so I had to bump the gauge up to read to 210.

I can (and will ) go faster but the conditions on Saturday weren't too great.

I also added a few more RPM to the limiter and increased the tacho range too.
