This might interest some here, it's a little different from the norm, so I'll give a quick rundown on the car and flesh it out later with more detail.



It's been done between me and my mate Ed (his car), he originally built up the frame as a cheap car to compete in the local regional championships in, total build cost was around

It's seriously suprising just how many man-hours there are in the little heap!

Right, job number one was to mock up and adapter plate to get the RX-8 engine onto the VW gearbox, as well as machine a new flywheel with a counterbalance weight to fit a smaller clutch, as the the Mazda unit is too large for the bellhousing.

So, a decent 2800lb pressure plate, plus an AP cerametallic 3-puck clutch plate, with the centre cut out and a VW one pressed in, made it's way onto the engine:



Which lets us bolt the engine on for mock-up of the ancillaries and hoses, before taking it back off and machining the various brackets and fixtures out of ally to keep the weight down - it's easier to mock-up in steel as you can just whack the MIG on it to tack something in place - but it's a hell of a weight penalty when you add up the amount of brackets and adaptors on a car, so all the final versions are ally where they can be.



New seat mounts to replace the steel ones, although we still haven't fitted em yet LOL



And a couple of hours work to get the exhaust manifold sorted out - unequal length manifold as the centre port is siamesed on these, like an a-series, so the centre branch meets at a different length to the others to keep it from causing problems with pulse tuning.





As you can see, still not touched the plumbing! Whistle

We've kept the standard intake manifold on this engine, as although it's quite large, it's an extremely good design, with several variable intake ports on it, replacing it with throttle bodies would result in a marginal top end gain for the cost of a huge amount of midrange.

A month or so later on and the car had the rest of the exhaust made up, a new crank trigger wheel on for the DTA to read (they're a right pain to make up!), most of the plumbing in, and the loom stripped out for wiring to begin, hence the big pile of old wiring on the floor:



A new rear bonnet to keep it all dry:


And we finally got the thing running about a month ago, there's still a few jobs left to do on it, and a lot to tidy up, but at the minute she's sat on the dyno having a flat spot sorted out and the top end mapped, as it had only been to 6500rpm due to an injector problem - the rev. limiter is at 9600rpm...

Hopefully, we should soon be back to this:



I'll get some video when it comes back, the engine noise is amazing.


We'll run this car for a year or two to prove the drivetrain, then sell it and make a new car with the RX8 engine (well, the new 1.6L version, when it arrives) in the middle where it should be, multi-link wishbones and a body with at least some kind of nod to aero LOL

We're working on it but not certain if we'll be ready in time, doors to go on and the geometery to set up yet.

Old vid. from the VW days, we'd just switched the car over to some dellorto 40's instead of the old Webber 48's it was on, took some tweaking later on to get that flat spot out of the midrange though:

Right, picking it back up from the dyno on Thursday, took a while but it's had all the variable inlets and the 3 injector banks run in all their various configurations to get the absolute maximum out of the car throughout the power curve.

Should have a final power run while we're there so I'll try to remember the camera.

Quick spreadsheet based on the figures I've got back after speaking to the guy mapping it, there are 3 slight dips in the torque curve where the variable valves switch over, which aren't on here, but overall a very, very nice spread of torque.

I can confirm, it does indeed hook up a proper wheelie when the clutch is dumped in first.

Might even be able to hold it through second and third with a bit of practise, not very nice on the driveshafts though LOL

Don't know how this sounds as I'm on the laptop - sound far too tinny on these little speakers, but quick engine clip:
