The RB30 TPS’s are notoriously unreliable. When they fail, the car runs, but erratic as hell.

Don’t ask me how I know

Not off to a good start, I unpacked the big box of rubbers that I have stored away in a tin trunk at the back of the shed and found that Rares have sent out four left front outer door rubbers and a panel van rear tailgate glass rubber. One step forward, two back- again. Regards Daz.


I feel your ...

I’d prescribe rum for that condition. If it doesn’t kill the virus, at least the hangover will be unnoticed.

Methinks 1/4 NPT, but I could be wrong.

It doesn’t have Any bypass hole at all, unlike the new one.


If the hole in the thermostat is the air bleed, it should have a jiggler pin in it. With the pin in place, there is stuff-all cross section left in the hole… it will flow next to nothing, and only burp air/steam. If it is a redneck ...

Flicked you a response over on the FE/FC forum. I think the spacers are ambidextrous.

... then again, mebbe left and right-hand versions were fitted to the EK Premier prototype
(sorry.... old joke).

Time to think a little bit about blower pulleys. Whilst vee-belts are traditional fare for road-going Normans, the dragster versions often got treated to gilmer belts. Part of me likes the idea of vee-belt tradition, but the other part of me says that there are a lot more choices of gilmer pulleys ...

From memory, the FE/FC ones are shorter but do fit. Some info on p18 of the Guide:

Cool progress

From what I can see, the rollers and valve stem tips are splash-fed.

As promised earlier, a better diagram of the oil supply. Oil comes up from the block in a pipe just like a standard grey motor, and connects to the bottom of the head behind the rocker cover (green line in the diagram below). It flows up through one of the inlet pedestals, then along the hollow ...

The front coolant port will get a simple water neck, and a pair of fasteners (ARP 613-0500 3/8-16UNCx½”):

I’m not going to run a water pump, and in theory could run the block dry as the methanol will run cold. I’m a little nervous of heat-damaging the head ...

The exhaust pedestals do not use the spacers. They are fastened using the rocker cover studs noted above, and some more ARP bolts (ARP 641-2500 5/16-18UNCx2½ “).

With the inlet and exhaust shafts in place, the twin shafts make the head look like a hemi head ...

Last lot of progress before I went back to work.

The inlet shaft pedestals have a 45-thou thick spacer placed under each to lift the inlet rocker shaft to the correct roller rocker geometry. Care needs to be taken in assembling these are the bolt holes in the pedestals (and the spacers) are offset ...
