PPC’s Rolls Royce Turbo track slag Featured

Track-day cars. Usually built to be small, nimble, and ferociously quick. Cars to enjoy to their limits on a piece of finely cultivated tarmac rather than the diluted and poor driving experience on the pot-hole riddled roads of the UK.

However here at PPC we like to do things a little differently. We wanted a track-day car, but one that fitted in with the magazine philosophy of a certain (small) degree of practicality. We wanted to lap the track five-up. And in style too.


So when PPC’s Kevin Leaper and Ed Hall first came up with the idea of a Rolls Royce Shadow track-day car it seemed like a perfectly sensible idea, but then they had been in the pub for quite a while having perfectly sensible pint sized ideas.

There’s nothing pint sized about the Rolls though with it’s 7-litre (ok 6.75-litre but there’s quite a bit of bore wear) all aluminium V8 engine mated up to the mighty TH400 three speed auto gearbox though.

So far it’s been lowered with fast road Eibach springs and Bilstein sports dampers making the ride more roller skate than Rolls Royce. Kev has painted the bodywork in matt black and stickered it up in true track toy style. Tyres are fat old 235/70 x 15 Avons that have proved their worth on the track as well as road and across scrubland on an autotest- what more could you ask for?

Well a bit more power really as that huge engine only seemed to kick out around the same BHP as a Zetec so some forced induction seems the natural way to go.

A trip to Germany’s legendary Nürburgring Nordschleife confirmed this, with the Rolls handling the bends without too much bother, but definitely needing some turbo torque to get the best out of the big V8 on the uphill sections.

And as Bentley thought the same thing back in the Eighties that’s the one we’ve gone for thanks to Rolls breaking specialists Montague and Co who donated a Garrett T4 to the project.

After building a Rover powered by a 27-litre Meteor tank engine PPC’s resident nutcase Charlie Broomfield reckoned he would make light work of fitting the Garrett blower to the Rolls.

A couple of weeks later and the turbo was sitting pretty in the engine bay, with the power steering pump removed and replaced with a more compact Mercedes A-class electric item to create enough space.

Charlie also plumbed in an Allisport intercooler to keep the boost temperature at optimum level and surprisingly the Rolls actually works.

The winter rebuild plans are to convert the car to LPG – the roller currently does seven miles to the gallon, and find a limited slip differential for the back axle. The aim? A sub 10-minute lap of the Nürburgring of course.
