Known History

Like many 934’s this factory Porsche race car was gradually updated over time to 934.5 specs. In 1978 the car began its transition to 935 specs and in 1980 chassis 0171 was converted to full 935 specs by Chuck Gaa/GAACO (Builder of JLP III) with the large 935 brake calipers, factory upside down gear box and titanium axles.


Car has a dyno time only 3.2 liter flat fan twin turbo motor producing 736 Hp and 587 lb ft of torque. The entire car was restored in 2007 and has very little time on the chassis. Every bearing, seal, etc. from the center lock hubs to the engine and gear box was sources new and replaced. New seals, pistons and bleeders for the calipers. New rotors , proper guibos for the titanium axles. New fuel pumps, rebuilt 935 peddle cluster. Everything mechanical was attended to.


The engine was rebuilt by a long time IMSA engine builder who was maintaining RSR, 934's,935's and 962 back in the glory years of IMSA in the 1970's through 1980's and currently still doing so for vintage racers of the same Porsche race cars today.


930 670 0171 was originally sold from the Porsche factory to famous Swiss privateer Claude Haldi a veteran of 34 running’s of the famed Le Mans 24 Hour race and 29 outings at the Nurburgring. Haldi was a consistent competitor in European road racing, hill climbs and the Monte Carlo rally.


Below is an overview of 0171's racing history but a good representation with some photos can be found on the Racing Sports Car web site at:




First outing was in May of 1976 when Haldi showed up at the Nurburgring and finished 4th in the 1000 kilometer race. After the ring the Le Mans 24 Hour race was run with 0171 qualifying and running very well but sidelined with a valve issue.


Later in the month of June 0171 competed in the 6 hours of Zeltweg and finished 1st in class and 3rd over all. Similiar results the following month in the DRM race at Diepholz. In September of 1976 Haldi teamed up with Herbert Muller at the Dijon 6 Hour race finishing 5th as a busy September took Haldi next to the DRM race at the Nurburgring, the Euro GT Imola and the DRM at Hockenheim. The last race of 1976 would be the DRM at Hockenheim where Haldi finished 6th.


1977 would be another busy year for Haldi and 0171 starting at the 6 Hours of Mugello driving with Laurent Ferrier to 7th place. For the month of May Haldi teamed up with Reinhold Jost for two races the first being a 6 hour affair at Silverstone for 8th place and then moving on to the Nurburgring 1000 km to finish 1st in class.


For the 1977 Le Mans running the car was put in the hands of Schiller Racing with an all French driver line up and Haldi and Schiller listed but never drove. Another great qualifying and start but due to a gear box failure did not finish the 24 hour race. Chassis 930 670 0171 competed in a host of other races for 1977 with top ten finishes and a 1st in class at the Brands Hatch 6 Hours.


In 1978 chassis 930 670 0171 competed in numerous races in Europe including another trip to the Le Mans 24 Hour but the car did not qualify. Haldi’s interest had increasingly been toward the 935 and the 934 was not getting much of his attention and was sold to the Minister of Sports for El Salvador, Enrique Molins, who raced the car in IMSA and the Caribbean series in North and Central America.

In 1978 Molins, who competes under the pseudonym of “JAMSAL”, first raced the car as a 934.5 in races like the Viceroy 500 at Rio Hato in Panama but then transformed the car into a 935.


Now in 935 configuration 0171 garnered 10th place at the Trans-Am Mexico with Jamsal driving. Mostly being raced through out the Central American series in 1978 and 1979, Bill and Don Whittington drove 0171 with Jamsal at the 6 Hours of El Salvador where Don clinched his 1979 World Endurance drivers Championship behind the wheel of 0171 finishing 1st in the race.


The first race 0171 appears to have competed in the IMSA Series would be Paul Revere at Daytona in 1980 in the GTX class finishing 17th and continued to run at various IMSA races till 1986.


Most notable finishes were a first place with the Le Mans winning Whittington's at the 6 Hours of El Salvador which also gave this car part of the World Endurance Drivers Championship. The Daytona 24 Hour in 1981 with an 8th over all finish, 10th overall at the Mosport 6 Hours in August of 1981, a 12th over all at the Sebring 12 Hour in 1985 and an 8th place finish in its final IMSA race at the Miami Grand Prix in 1986.


Car is in its 1981 Daytona livery and has competed at the Monterey Historic twice and the Wine Country Classic once since restoration was completed.


Car has great European, North and Central American racing history that should qualify it for just about any vintage race series or event.
