I know that WRC cars are LTD to 300bhp but how do they achieve such amazing Torqus figures, and does anybody know of a good site that explains and shows the rally car stats figures etc? .


cheers Scott

 

sorry i guess you realized i meant to type TORQUE.

It does it, because its basically a 600bhp engine, that runs out of air at 6500 rpm, ie long before it reaches its full power potential.

It uses a massive VF15 turbo, is lightened and balanced to the extreme and runs ridiculous amounts of boost. It has fuel rails, thicker than your thumb and injectors that look like cotton reels.

Oh... and a 2.5" exhaust system

An interesting fact is that todays WRC cars set quicker stage times than the 500bhp+ Group B cars that were banned in 1986.

 

Does anyone know how the WRC Scooby engine holds together so reliably with at least 30% more torque than an STi? The limitations of short main bearings in the flat-four layout and the all-aluminium block are just as relevant to the competition version, surely.
These limitations are supposedly why the Scoob can't reach Cossie power levels and shouldn't be taken too far by tuners.

 

Les not forget how often these engines get rebuilt and their relative short life. If money was no object, Im sure more of the STi engines would hold together

Not to mention the fact that a WRC engine will only share engine layout with the road car and probably NO engine components, and will cost many tens of thousands of pounds

I was given the chance to have a really good look at the car in San Remo.

I was amazed at how many components it does share.

The main bearings are larger than the standard car, in diameter not length. I have had the same work done on my RA. This improves the load distribution onto the block, keeping the bottom end much more rigid.

A WRC engine has a designed life of 1500 miles!!

The rest of it? I'm sworn to secrecy
