Went for a run to the airport on the bike to meet a friend who was doing a quick stopover in Brisbane. Make sure when English is NOT the common language (I do not speak Japanese) that you confirm the day... I was a day early :) Anyway I'll head out tomorrow morning then I'll be back in the afternoon catching a flight to NZ...

Tomorrow (time depending) I will remove the OEM lines and power up the tank pump to test for leaks (at least before the surge tank). Will get a sparky in whilst I'm away to wire up the surge tank.

So was a late start in the shed, not till about lunchtime.

Bracket for the surge tank. Where the jack used to go. I may add a brace as whilst it feels solid who knows at track speeds.

I might see you at the airport tomorrow morning then....

I fly out to Singapore on the 9:00am flight to overnight for my Indonesian Visa and then arrive in Jakarta monday night for my start on Tuesday morning

Nope, will be at the domestic in the morning, international in the afternoon. Best part is flying home on the Emirates A380 again.

I have to put up with an A330, but at least I am up the front in the comfy seats.....

smy0003 Rev 9 asked me if they could use the photo :)

Back on topic, thanks to Blake for a heads up on fake tomei FPR's, mine is missing a serial number so according to Tomei it is a fake...

Cleaned the filter out and re oiled it, this was what was tapped out after the first of three washes. K&N have ceased to make these filters so need to preserve this one, Pipercross does make one that may fit (PP11) and Competition Systems is getting one in for me

GOOD NEWS - car works and fuel pressure is stable... Had a few leaks to fix up, AN6 hose is just a bit big for OEM hard lines so additional clamps had to be used. The surge tank is not very loud at all.

It works... Surge tank cannot be heard over the exhaust :) The Fuel pressure is not as stable as previous, some fine tuning to be done with the correct orifice for the Radium surge tank.

http://www.radiumauto.com/FST-R-Fuel-Surge-Tank-with-Integrated-FPR-P348.aspx
INTERCHANGEABLE ORIFICE
The FST-R is equipped with an interchangeable orifice inside the regulator. This part can be swapped out with either of the two extras included in the kit. These orifices have different inside flow diameters. This is required in order to match the pump(s) flow rate, fuel hose restrictions, and targeted base static fuel pressure. The 0.10” black orifice is a good starting point for low flowing fuel systems. However, if multiple high flow pumps are used in a low static pressure system, a different orifice can be easily swapped using common tools. See the servicing information below for more details.

An orifice that is too small can cause fuel pressure spikes in aggressive driving situations. This phenomenon occurs because the orifice cannot discharge enough fuel when the diaphragm instantly changes from a closed position (WOT) to a fully open position (deceleration). This can create a noticeable momentary rich condition until fuel pressure stabilizes. Another tell tale of the orifice being too small is if the pressure adjustment screw has been completely backed out and base static fuel pressure cannot be obtained. However, do NOT mistake this with an overly restrictive fuel return back into the tank. As a simple test, run a hose directly from the FST-R into a bucket, bypassing the return line and monitor fuel pressure.
Conversely, the orifice is likely too large if a small set screw adjustment creates a unstable pressure change. The higher the system’s targeted base fuel pressure, the smaller the orifice should be for greater stability.

Orifice to Fuel Pump Flow Rate Examples
Black 0.10” Orifice ----> *100 - 500 LPH @ 3Bar (43.5psi)
Silver 0.18” Orifice ----> *350 - 900 LPH @ 3Bar (43.5psi)
Gold 0.25” Orifice ----> *750 - up LPH @ 3Bar (43.5psi)

*These recommendations are only general suggestions. Both the backpressure created by the diameter and length of the fuel return hose and the desired static fuel pressure variables will have an effect. Orifice calibrating may be necessary.

Working Mon-Fri in New Zealand is a bit painful when you have car work to do...

The revised rules for WTAC Clubsprint require that OEM headlights be fitted, this is aimed at the people who remove headlights to install intakes, however it has also made my car not comply. The rule maybe revised to required working headlights, but unless the rule is changed I have to make my headlights OEM. Strange that in Clubsprint you can fit aftermarket traction control and diff torque slitters but not aftermarket headlights....

Since there is nothing left of the OEM headlights in my car, including wiring, I should be able to get away with having OEM type covers. Take the covers off and wollah working headlights, worst case is OEM have to go back in and then they need to be manually wound up. The bonus of covers on the Jetstream ones is a slight improvement in aerodynamics.

Plan is to have the covers sit flush with the existing light

Pinned together for a test fit

Plan will be to screw the cover in place, will not be a simple job to remove, however may find another way to attach them for quick removal.

Had a rethink after cutting out the 3 shapes. Plan was to heat the acrylic up in the oven and make the shap of the cover, however it is a complex shape so used some modelling clay that was for another job. Clay plug that the heated acrylic can be placed on (when hardened. Or I can make a mould and press the acrylic into shape.

If you had of done this early Feb I could have gotten you some vacuum formed covers made when I got my panels done for the S14.
3mm thick, and very light, boot lids is less than 2kg, and the guards are around 1kg each. Bonnet is under 2kg, but being two piece, may not be useable.

Looks like the fuel pressure loss issue has been fixed, now need to tweak the surge tank to find the correct orifice size to get the pressure 'stable'.

Interesting development at Lakeside was that the fuel pressure got TOO high, more than likely as a result of the fuel getting TOO hot. The surge tank and boot in general was very hot too touch. May have to add some heat shielding, it never ends.

Rego is due soon and the decision is to NOT renew it. After my small off at Lakeside on Sunday a full cage may better suit my intentions going forward.

End of the journey as a road registered track car... Plates will not be sold :)

You're tempting me to run manual brakes...

I've seen some threads where people have changed all their hard-line size too, not sure what bore master to the go with, running NB8A brakes. And deciding if I should locate the master higher to increase pedal ratio above 5:1.

It is worth it, if you are going to track the car. I should have done this a long time ago...

Maybe you could consider a remote brake booster so that your engine bay stays 'clean' but you still get the ease of 'boosted' brakes.

One day soon I'm installing a remote clutch reservoir, happy to give you some advance warning so you can have a look at my setup.

Yes the pedal pivot point does need to be modified.
