Hi,

A quick post to say hello and hopefully tap the minefield of information on here for any history/pictures/info on my car.

Lucky to own the FRPP Focus WRC8 that was unveiled at the 2003 SEMA Show in Las Vegas in 2008.

With this being quite a rare engine, there are not very many specialist for it in the UK, so hopefully some kind person could point me in the right direction of a workshop manual for a 5.0 Cammer and service parts?

Thanks again

Darren

I think you are describing what in the US is called an FR500-C engine Darren. The engine is basically the same as any other n/a 4 cam 4.6 with the following exceptions;

Block
The block is a 3.700 (94mm) bore block with special thin liners to allow this size bore. The heads are next generation 2000R Cobra heads with raised intake ports requiring the manifold that came with the car. The valley in the block was raised to mitigate crankcase pulsations as pistons go up and down. The raised block's valley precludes the use of any factory superchargers because of manifold interference.

Cams
The FR500-C cams were designed to provide a very broad and flat torque curve for road race applications. It does this very weee. Applications requiring high rpm power might need to rephrase the cams. Applications like a performance street vehicle will find the cams quite attractive.

Pistons, Rods, Crank, Oil system

All of these parts pretty closely mirror the Terminator parts and are quite robust. If I remember correctly, the pistons are high compression 11:1 items requiring premium fuel.

Any of the Ford OEM maintenance manuals available from Ford for DOHC 4.6 engines will cover the disassembly / reassembly details quite well.

Thanks very much for your reply, I have been fortunate to have been put in contact with several people in the US. I have Steve Saxty the author of the secret fords books for this.


Im trying to fill in the part of the jigsaw on how it was sold on from the PDC @ Dearborn into a private collection in Texas.

Next appears for sale in 2013

During 2017 a good friend acquires it from a dealer in the UK and then onto myself last year.

I have it on good authority that it’s sister car the Focus RS8 was crushed at the Dearborn PDC during 2017.

One Of Steve Saxty’s contacts put me onto the Fall 03 Focus Fanatics magazine, which has a 6 page article on the cars.

Yea they did, Bob.

The kick in the pants is that is not your run of the mill ModMotor. It is the aluminum big bore 5.0L version that Ford used in their FR500-C pure race cars that could not be licensed for street use. Sort of the same story as the CobraJet cars. The upshot is that the car weighs in somewhere between 1000 and 1500 lbs less than a Cobra and the engine is north of 450HP in n/a trim. It's worth saying one more time, in a Focus! We are talking warp drive capabilities if you can control it. :)

Because that car is one of only two that Ford ever built and it is the sole survivor (the other was crushed) it is worth a king's ransom especially with all the original FRPP badging and graphics. Literally a stunning vehicle!

wow that really is amazing. congrats op!

i am especially intrigued by those "factory" fuel rails. return-style that will fit on 99+ heads? don't think i ever saw that before

edit: oh i guess since it is a custom one-off intake manifold, they made it for those rails, although they do appear to bolt up at the same place as 99+ manifolds

I think it may be the original FR500-C intake, Chris, with its ECU selectable dual runner paths that provided a longer intake runner for lower and midrange torque and at higher engine speeds it would swtch off an internal bypass that would modify the intake runner path to a shorter one for upper rpm performance. If it is, it is one of the fancier intake manifolds Ford has produced. I believe it was only manufactured in magnesium, making it quite light weight and like the rest of the car quite valuable.

With respect to the fuel rails, I suspect those are a McLaren piece built specifically for the car.
