R Gruppe Porsche 911 for sale

It was good to hear from many R Gruppe friends after my recent post on the late Cris Huergas. One name that popped up in my inbox was Hayden Burvill at WEVO, who is about to put his 1972 Porsche 911 up for sale.

The car in question is Kenny: a 1972 911T built in May of that year and finished in rare Gulf Orange. The ‘oil klapper’ side oil-flap 911 now runs a 2.4S engine, rebuilt by Jerry Woods, but the matching numbers engine comes with the car.

Kenny has been owned by a handful Porsche enthusiasts in San Francisco’s Bay Area since it was new in 1972. It’s the car that inspired the Aussie engineer and product designer to begin modifying 911s – initially for autocross competitions – and develop a range of chassis and drivetrain products to sharpen the air-cooled 911 driving experience.

Products developed on Kenny include the famous WEVO shifters, engine and transmission mounts, anti-roll bars and suspension parts. Kenny is also fitted with several prototype parts that never went into production, such as the WEVO brakes that I vaguely attempted to buy several times but could never convince him to sell.

The WEVO brakes remained in prototype due to projected retail price against the value of air-cooled cars at the time. The numbers would probably make more sense nowadays, but life has moved on and there are other products out there. Hayden instead developed his 5-speed conversion for Porsche 356 models and that has been going well since launch.

Kenny has been part of my world since 2008, when I took my first trip out to San Carlos to meet Hayden and Tracey at WEVO. They could not have been more welcoming and our friendship continued when Twinspark Racing became WEVO’s official European distributors. I was a partner in Twinspark at the time, along with my friends Leonard Stolk and Lex Proper, so we did a fair amount of business together.

Hayden’s exploits in historic rallying on events like the Peking to Paris alongside Steven Harris and more recent rallies with Alastair Caldwell have kept us in touch. Our last time together in person was when Ciara and I joined H and the EB Motorsport guys for dinner on the beach at Zandvoort after the Masters Historic Grand Prix in 2018. Great times.

The world has turned on its head in two years and the pandemic has shifted life goals for both of us. Hayden’s responding by selling some cars and doubling down on a sustainable lifestyle. His 993 daily driver has already departed and Kenny is next on the block. The cool blue 912 is also likely to go.

Long-time followers will remember our feature on Kenny, which ran in one of the Porsche magazines back in the day. Jamie and I took the car to Pacific Grove near Monterey before sunrise and shot it on the coast as the sun came up. It was an unforgettable experience.

I’ve driven a lot of miles in this car, incuding down through the redwoods from San Francisco to Laguna Seca (above), where the car has seen many great days on track. As Hayden was an early R Gruppe member, Kenny was one of the earliest R Gruppe cars, attending all sorts of group events over the years. There is an air of authenticity about this one that later R Gruppe creations can’t hope to match. The aim is to place it with someone who will appreciate the history and keep piling the miles on, enjoying the car while we are still allowed to drive them.

Hayden wrote up a great spec on the 911 and you can download a pdf of that here. I’ll put the main points below. This is a special 911 with room for cosmetic detailing if you want to go that way. I would probably just run it as-is (with one of Jonny’s electric air conditioning kits, of course).

1972 Porsche 911 for sale – Specification

Engine

That original engine was replaced by the current engine, a 2.4-litre MFI engine from a 911S that was dressed using the original yellow “T” fan shroud and a combination of 2.4S intake system, recalibrated MFI pump and the highly regarded Elgin “Mod-S” camshaft grind. The engine made ~195hp at 6750rpm on the Jerry woods dyno with airbox, filter and Abarth muffler installed.

The engine was detailed when it was installed in 2004 and the installation is otherwise stock. There is no external oil cooler, it has the stock MFI fuel pump mounted in stock location, stock fuel filter and fuel cut-off valve all mounted and functioning.

WEVO SS engine mounts are fitted. The current exhaust is stock MFI heat exchangers (cabin heat connected) and a stock MFI muffler with the period correct ribbed outlet. The accessory package that comes with this car includes a rare Abarth 4-outlet muffler, an equally rare and unique 6-outlet muffler (for when 4 is not enough!) and a rare, unused 2 x 2 muffler with a pair of chrome outlets exiting wide; one on each corner of the rear bumper.

The engine has a WEVO 915 Streetlite Clutch kit using a spring-centre friction disc. The low inertia and added performance of this clutch kit is especially noticeable at full throttle in second and third gears.

Transmission

As one would expect given WEVO’s unique expertise, the transmission has been through a variety of revisions, at times running a WEVO super lightweight spool instead of an open differential. It currently has a Porsche factory ZF limited slip differential. It has a very deliberate build suited for easy street driving, or aggressive track driving. 80% build configuration giving the maximum friction surfaces, then carefully shimmed to have a very light pre-load of only 10 ft/lbs.

This configuration gives a high locking action during aggressive driving and easy rolling and steering at low speeds. The transmission has a suite of WEVO products, including XT 100 Side Cover, WEVO 915 GateShift kit and XT 032 bearing retainer plate. The gearbox is in great operating condition and needs no repairs.

Interior

Hayden’s interior spec goes into quite a lot of detail but, in short:

  • Fitted factory sports seats
  • Abarth 360mm sports steering wheel
  • WEVO 915 shifter with +40mm lever (my 911 also has this: perfect mod)
  • WEVO PSJ shift coupler and XT 147 clamp
  • Accessories package includes bespoke carbon fibre seats with custom rear cage

Bodywork

Again H has added a lot of detail to the bodywork section. In summary:

  • Sunroof 911 finished in original Gulf Orange
  • Rust-free car that has lived in California for almost fifty years
  • Distinctive WEVO-logo graphics
  • Presented as RS with SC/Carrera rear arches
  • Fibreglass bumpers and ducktail
  • Bespoke front brake cooling ducts
  • H1 headlights with Euro rear lenses
  • Accessories package includes original steel rear bumper and deck lid, and an early S steel front bumper

Suspension

See the full pdf for details of this. One could hardly ask for a better suspension setup on a sports-purpose early car:

  • 21/26 torsion bars
  • RSR raised-spindle front struts with Bilstein inserts
  • WEVO Camberking top mounts with Teflon monoballs and carbon fibre cross tube/strut brace
  • Weltmeister 19mm front ARB
  • WEVO Spring Plate system rear end (now unobtanium)
  • ’76 trailing arms with SRP monoballs and WEVO E-Z pins
  • Weltmeister adjustable rear ARB
  • Koni adjustable rear dampers
  • SC CV joints in stock driveshafts

Brakes

Highlights include:

  • Aforementioned WEVO prototype billet aluminium calipers
  • Designed to fit inside 6×15 wheels with a nod to 930 brake performance
  • 315 x 28mm front brake disc
  • standard 930 rear disc with handbrake bell
  • 930 pads for ease of replacement
  • Accessory package includes set of new discs and all brake servicing literature

Wheels and Tyres

Kenny runs on nicely restored 7 & 8×15″ Fuchs, with Avon CR6ZZ Classic 185/70 front and 215/60 rear tyres. The spare is a 6 x 15″ Fuchs with a 185/70 tyre.

Enquiries and Price

It can be difficult to price cars like this and would be all too easy to get that wrong. Setting the mods aside, we have a low-owner ’72 oil flap 911T with sunroof in a relatively rare colour with a matching numbers engine and the original panels ready to be refitted. The only major change is the SC arches.

Adding in the mods we have a Jerry Woods 2.4S MFI engine making circa 200 horsepower, custom WEVO transmission with pretty much everything you could pick from the catalogue, custom suspension, custom brakes, simple but desirable period trim that one could improve and so on. It also comes with a ton of additional parts, including the original engine.

The key to this car for me is that it is not fake. It is not a poser. It was forged at the centre of air-cooled 911 culture and has been driven and developed over twenty years of ownership. What was created specifically for this car may now be found on thousands of 911s all over the world. But there is only one original. Does that story add any value? Well, the buyers will decide. What price romance nowadays?!

So to the price. Hayden is open to offers circa $150,000, which is £114,000 or €126,000. To find a similar rust-free 1972 911 and fit it with an S engine with the WEVO bits one can still buy would easily exceed this. And that car would not be built by WEVO. Add in the unobtanium, the spares bits and who knows what else the boss will include and you have a unique piece of air-cooled history.

The car is located in San Francisco, but can of course be shipped anywhere in the world. I am helping out with this one should it make its way across the pond to the UK or Europe, so you can contact Hayden via WEVO.com or drop me a line – john@johndglynn.com – or give me a call on +44 7565 348453.
