After the comment I was reading in the “914-6/904 project begins” thread I felt the need to inform some of the members of this board about the 914s in IMSA or the 914 GTU. I am currently involved in research to write a book about this very subject so I will share some of my findings.
Between 1971 and 1987 there were forty-two 914s built and entered in IMSA sanctioned events in North America. In 1971 and 1972 the cars sported the factory M491 option package or their equivalent built by the privateer. The extensive use of fiberglass in the hood, rear deck lid, bumpers and rocker panels lightened the car while the 911 engine upgrades gave the horsepower to make this car competitive against all racers. Starting in 1973 the cars had started to evolve into homegrown and sometimes innovative thoroughbred built by Americans with that “can do” attitude. It was not that Porsche didn’t do a great job converting the 914 into a race car it was just that the development done in 1970 was becoming outdated. Wheels and tires were getting wider and this would drastically affect its shape as the fenders became wider and body panels were constructed of fiberglass. The Porsche factory never constructed a tail or developed any aerodynamic aids for the rear of a 914.so this would become the area of most diversity. The 914 competed in the IMSA GTU class which allowed a 911 engine starting at a two liter displacement and expanding all the way up to three liters by the end of its eligibility. There were also some 914/4s that competed; they were allotted a chassis weigh savings for their lack of displacement and two cylinders. As the handling, acceleration and speed of the 914 were enhanced by these advancements the chassis required more strength, this was accomplished by the extensive use of tube framing and suspension reinforcement. In some cases suspension components were borrowed from the 911 RSR and 935. Once the cars became firm and fast they needed improvements in their braking capability. As has always been the case the 914 borrowed calipers and master cylinders from its Porsche siblings, a few examples even used aircraft brake calipers. |

Boy does this thread bring back memories. I just saw this thread and the car posted in #106, the yellow #54, was a car that I knew very well. I bought that car from Dave White, prepped it for the Daytona 24 in 1976 and co-drove with Hal Sahlman and Alex Job. I was working at the Porsche dealer in West Palm then and we put the whole deal together in a two month time frame. We ran Goodyear street tires and ran the entire race on one set. That's a story in itself.
Then comes along post #107 that shows the Altman 914-6. That picture is from the the last year of the Columbus 500 in Ohio. Mark & Gary co-drove my 914-6 at Elkhart Lake and I co-drove with them in their 911 in the last 6 hour makes race at Watkins Glen. That 914 was a full tube frame car that they built from a set of plans (drawings) that they obtained. They had major teething problems with the car. I don't know whatever happened to that car. Their 911 went to Jay Kojeller in Toledo. Great memories. |

@9146GUY is none other than Steve Southard. He has been racing for a while now and most interesting to this crowd he campaigned a 914/6 for many years in IMSA.
Steve also owned and raced one of the original 6 Ginther Roadsters. I picked up some parts from Steve last year and ended up talking with him for hours! |

You asked if about the yellow van....Nope As for the spin I don't know who was driving at the time but I can tell you about a joke we were having during the race. There were several cars that Goodyear supplied street radial tires for us to run the race on. Our car was the only one that hadn't changed tires when the rain started. One of our drivers, Hal Sahlman, came from off shore power boat racing. So I made a comment to him that he would be the driver during the rain because he was the one with all the experience on top of water. Not saying it was him driving at the time but....... BTW we finished the race on the original set of tires we started on. Try that today. |
