Wow! I post about buying thousands of dollars worth of carbon making custom body parts and no one pays it much attention. I post about needing some $5 tyre valves and I get half a dozen posts in a day.
Found metal valves OK. Seems they are used on motor bikes quite frequently. A bloke in the tyre shop had 4 in a drawer and only wanted $5 each for them.
Fitted the valves during lunch and dropped the tyres and rims off to be mounted. I went back after work to pick them up. The guys came out to meet me and apologise for a scratch in the edge of the rim. The powder coat has come off a 15cm section where the tyre meets the rim. They were trying to mount the tyres with no lubricant so there would be no slippage at the track. I was a little upset, but figured that sometimes accidents happen. The manager refused to take my money, and has offered me a set of tyres at cost to make up for the error. He feels they have 'all but ruined' the rims.
Like I said in previous posts above: They are good guys down there at Cluse Bros Tyres.
Allan- I do believe tyre pressure monitors are illegal at all CAMS events. It would be a handy tool for doing setup work etc though. ALso let you know exactly how long it takes to get the tyres up to temp.
*edit* "Any control valves that automatically manage tyre pressure are forbidden". A CAMS Scutineer may take these either way.

Just did the same measurement on my car (already conveniently airborn) and got 27mm. Your guards should be fine. Just make sure they're rolled neatly, I had one of those tabs under there catch on mine.

You are going to do that measuring exercise with the car back on the ground I take it.
I actually placed a jack and pad under the tyre and jacked it up until it was supporting the car. At full compression the wheel is only a couple of mm outside the guard. The camber helps, as does the natural arc of the suspension. Full droop is the worst case scenario, and even that is not too bad.
The rears are even closer- about 8mm outside the guard at full droop. I did not bother compressing the suspension as it is clear that a decent rolling job will get the rear clearance I need.
Thanks for the vote of confidence Spencer, I will have a think about the front guards and decide what I am doing. I think I will still box the rear of the guard as there is a lot of tyre outside the lower guard. The front edge of the guard will need some sort of air guide, canard or flare to get air around the lower part of the wheel. The more of that rolling aero nightmare (wheels) that I can get inside the body work the better.
The car has been up on jack stands for nearly a year. Makes it hard to wash, LOL.
Go and see Morpowa tomorrow- my dash, injectors fuel rail and other bits should be in this week.
I looked at the spare shell tonight. I was going to start figuring out the fuel system. Pulling back the tarp and lifting the boot I realised that I hid everything that was sitting on the floor one day in the boot during a clean up. Due to the cold, and a significant lack of motivation, I closed the boot and walked away. That is future Ben on Holiday's problem.

So this afternoon I moved the cars around and put the spare shell in the shed. The race car is next to it, leaving the red car out in the cold. After some reshuffling of what could be described as rubbish, but I call 'spares for if I ever need them', I could get access to the boot of the spare shell.
I started mocking up the fuel system. A pic is attached. The thing I need to find out is where the factory fuel line comes through the boot. I have two holes on each side of the floor. The fuel filter is on the left side of the car, but the fuel lines appear to run through the right side hole. (The fuel lines in the spare shell are bent all over the place, so I am having trouble picturing there proper location.)
and here is a pic of the car with the wheels on. My son reckons it looks 'angry' or 'mean'- apparently it looked 'happy' with fluro green wheels.

How do you intend to get the fuel into that tank?
And after going through archives I can tell you the fuel lines run across the rail under the front of the original tank (over the diff) and enter on the right side.

As andrew said they come through passenger side section. Ill be hooking up my surge tank soon when it comes. Ill just use stock tank and tap off those fittings for return and pick up to surge tank. Those wheels... Aaron approved. Verrrry nice

So who is right??? Until I pull the tank out of the track car I won't know for sure, but I was running with drivers (right) side because it looks like the line backwards from the fuel filter goes over the diff and into the right side of the car.
Allan, I already have a bosch 044, surge tank, and Holley lift pump. Not sure how I would save money not using them?

I guess it depends if you use speedflow fittings or not for the cost saving part, but no reason why you can't use the 044 in tank (you can get a filter sock for them) I'm just not a fan of all the extra plumbing and low pressure pump, the only extra pump i would add is another 044 so you can run E85 if you want later (and coat the inside of the fuel cell with tank sealer)

I just pulled my fuel lines out of the car yesterday, but have put the rear cradle back in. I'll post a photo tonight. The standard tank has feed & return coming through the bottom of the driver side of the tank & breather coming out the passenger, all lines run under the diff to the passenger side and even join the brake line & run down the passenger side chassis rail to the engine.

Just looked at yours on toyodiy.. says fuel return for yours should be passenger side. Main fuel line (and fuel return line 2)drivers side... strange..

Ahhh. OK. Track car is a 93TT. The spare shell was a v8 (unsure of the year) Other car is 92TT. I might need to get under the track car and figure it out for myself.
Allan- I understand what you mean, but I have some of the speedflow fittings in the shed as well. I was thinking of finding a self contained in tank reserve/surge tank and pump from a late model wreck(they are a popular OEM design) but I just do not have time to go poking through wreckers finding something suitable and then adapting it to fit the fuel cell. Paul is doing something similar with the factory pump assembly from his Rx-7 to feed his surge tank and O44.
I am still deciding whether or not to buy a 45degree neck for the fuel cell, or just use an angled funnel. Unlike a proper race car where refuelling might be a hurried activity I should be fine to use a funnel to fill it.
I am going into Outlaw speed shop to look at what they have next week to suit the tank.

I thought that too. But trust me, once you start having to fill it that way, you'll regret not having some kind of neck on it to make it easier. Especially when you start having to go around a rear wing to get at it.

OK, so Andrew got me thinking with his "how ya gonna fill that?" question. I went out to the shed with a fully jerry can of fuel and had a few goes at it. In short it sucks.
New idea: put tank in easy place to fill and work from there.
I have also decided to pull the tank on the race car and just build it in there. I wanted to build the system on the spare shell and then transfer, but I'll end up doing things twice (welding tabs etc)
