Rotus Project Build
« on: November 25, 2018, 10:38:54 AM »
I have had an e-mail in for some advise on this fascinating project.

Interesting he designed the backbone chassis with CAD and built it.

Started out as being a hill climb car, but looks like now the build is coming along its going to be an amazing RX-8 engined road car :bravo_2: .       
All the best Clive

Hi there,

Yes the intention was track days after I was refused a national b licence on medical grounds, as I was going to do hill climbs, with a view to use this car in the sports libre class after I got a few years under my belt.

But, with track days you get more time than a 1 minute run up the hill twice a day......

Bit new  to all the forum stuff so I'll post some pics when I find my way around the site, the build has advanced a little since the other pics, so keep tuned.

Question while I'm here, I've been speaking to Clive the other week on fuel pumps, filters etc.
I've ordered all the aluminium sheet today to build my tank and Clive had mentioned 8mm tails on the pump, so here goes with a few questions if anyone can help?.....

1. On the outlet and return, with 8mm tails, is that o.d. Or I.d.
2. Will push fit fuel hose suffice for the pressures of fuel injection or should I be using JIC -6 fittings?
3. I want to retain the stock rx8 instrument panel, the stock tank uses 2 X fuel senders, I was intending on buying a universal sender, but the ohms need to match the clocks, looking on the manual, the stock sender is 9 ohms when full and around 322 ohms when empty. I could possibly get a sender in that range, but if I use 1 instead of the 2 in the stock set up, is something likely to get confused?.. I don't really want to add an aftermarket fuel gauge.....

Any help is greatly appreciated...

Oh, and while there's no glass in I use the overhead crane lol it's still light, even with the newly fitted integral roll cage.  I gave a pit, but when I'm going to be working on the new wings, I want the car at a decent working height 😆
Its just Rotors and GRP

Stock rx8 pressure is 4 bar, Clive wouldve meant 8mm id. Nothing fancy required upto you i just use 8mm id fuel hose with fuel clips ( not jubiless) they fix to the rx8 push fit fuel hose connector at fuel pot and fuel rail.
The rx8 runs a returnless fuel system so unless intending to use a swirl pot not needed.
That said i cant run my westy below 1/4 of a tank else i get fuel cut in the corners so best practice baffle your tank or incorporate a swirl pot within? Ive added a fuel filter a systec 1 within my engine bay the rx8 fuel pot houses a filter inside it that can block over time...it all depends what you decide to run..
I didnt manage to get the fuel system to work on 1 sender..Paul on here has in his 8 converted mx5...worth reading his thread and asking him.

Track work...cool...comes with a few headaches ive found the hardway with the Westy on slicks...
Oil starvation...oil moves up the fill tube away from the pick up pipe on hard right handers...best to fit a sump baffle or gated sump and a catch tank....i also dumped the omp. Its stilll on car blindly working but it does not inject 2t oil.
This allows me to run 5w40 fully synthethic oil and so far so good.
My car was for racing but i got demoralised being in the top class with a 1300 lol so trackdays it is for me.

Worth a read of mine too. Ive pretty much documented the whole Westfield rx8 journey since buying it...taking in apart, rewire, crash x2 engine blow ups still chasing the castle combe 1.14 lap.
