Two Weeks in a 1972 911: Rennsport Reunion V (Part III)

PART III | Bring it home *author’s note: while launching the new site, I realized I’d never posted the third part of the RRV drive in the ’72 911! Please excuse the delay, here’s the rest of the journey: click here for PART I click here for PART II   Grand Canyon   Normally I’m a planner. I map out my trip in excel, keep a running tabulation of expenses, mileage, etc. Accordingly, I’d made all the appropriate reservations and budgeting before I left. However, on Sunday night it had occurred to me that I’d never been to the Grand …

Rennsport Reunion V: Two Weeks in a 1972 911 (Part II)

. Two Weeks in a 1972 911: Rennsport Reunion V PART II | Rennsport Treffen Tehachapi Tuesday morning Chris and I got on the road at 6:30 – we had a track event at Buttonwillow Raceway  ( buttonwillowraceway.com ) the following morning (already?!), and both of us wanted to be able to get to California early enough to relax and get a good night’s sleep. Heading west, the scenery was consistently and continuously impressive, one gorgeous vantage after another. The rest of the group at the La Posada – which had grown by 3 additional late model Porsches overnight – …

Zuffenhaus 3.6MFI

MFI for Mary.

It’s been a while since we’ve updated; as we’ve been quite busy (and thankful for that!)  since our last post. We’ve been sorting our Celette benches, adding some in-house prototyping capability, continuing physical upfit (construction) of the facility, and making some strides on the Mary Stuart RSR project. Let’s talk about Mary. She’s getting proper MFI.  (If you know anything about us, you know this makes for big smiles around here.) The engine for this project is a 3.9l based on a 3.6, and as such was not designed for use with mechanical fuel injection, although the mounting bosses for the …

New Friends from the Vaterland!

Zuffenhaus was pleased to meet and visit with our newest friend from Germany this morning: Mr. Stark surveyed the shop for a longtime friend and classic Porsche racer; both are Mary Stuart RSR enthusiasts and are patiently awaiting the first production run of bodywork for special projects back home! Look for an announcement about availability in upcoming months, and we look forward to visiting with our newest friends on our next occasion overseas!

WERKing the ‘72, part II

Engine out, Discovery. The PO and I had reviewed the records/service history together and the only 2 deviations from original configuration were the installation of Weber carbs, and a repaint and color change. The webers (sourced from PMO) were installed in 1988 during a total rebuild (including P/Cs) at 56,760 miles. Soon after, the car began its “Black Phase” (it was originally Light Yellow.) It was treated to new carpet, dash, trunk liner, targa top upholstery – you get the picture. Incidentally, I was in my own “Black Phase”, in ’89/90, as a sulky high school senior: (photo included for …

2012 RGruppe Bergrennen, part III

Still catching up at work, so this post comes to you from my home (at 5:00am on my day off, no less!) More Bergrennen – the LOCOMOTIVE: What could be more fitting? The Shay geared steam locomotive was hill-climbing in WV long before the first 911 met an incline. From the Cass Scenic Railroad website: “Invented to do the impossible, the Shay logging locomotive was designed to climb the steepest grades, swing around hairpin curves and negotiate frail temporary tracks.” Sounded Bergrennen to us… A handful of RGruppers hill-climbed via Shay Engine #11, climbing (and descending) 9% grades and two …

WERKing the ’72. part I

A 1972 911T Targa arrived at the shop on a rollback early in May 2011. An accompanying telephone call informed us that the Porsche had been in storage since 1994, and had been towed to Zuffenhaus to be returned to use. The Targa’s VIN was not in our database, nor was there any record of previous visits by the owner – this was unusual, as new clients rarely send their Porsches to service provider without at least setting foot in the facility! More interesting was the condition – aside from a color change and carburetor install, the Targa was VERY …

2012 RGruppe Bergrennen, part II

Now that we’ve been back from the West Virginia event for a week and had time to decompress and begin to deal with the pile-up that occurs in the shop schedule after being out of town, it’s time for more 2012 RGruppe Bergrennen images! Each day of the event I was struck by the perfect timing of Autumn in the WV mountains – if there were an icon suitable for association with this gathering the image above would be it! Lots of autumn leaf action: But I digress. The parking lot is the foundation of an RGruppe event as I …
