Porsche 924 back to the 70s: reunion with the Peiseler measuring wheel

The past is not behind us, but in the basement. After all, we've been doing this for almost 70 years - that is, this mess at auto motor und sport . And when we hear that we have the Porsche Received 924 as an endurance test youngtimer, we descend into the catacombs of Motor Presse Stuttgart GmbH & Co. KG. There lies what is far too valuable to have an inventory number or to be written off: the myth of a uto motor und sport .

A fleet of Peiseler towing wheels hangs from the ceiling, layers of dust cover Zarges aluminum cases containing measuring machines and yellowing thermal paper. At the back, yellow-red styrofoam cubes are stacked up to the ceiling. On shelves are measuring devices that once indicated the sound pressure level of twelve-cylinder sports cars that slurped out of many Weber double carburettors.

We drag everything up, then crawl down again because, of course, an important cable is always missing. Then we have some things with us twice or three times, but not others at all. So we decide that this balances out. After all, we don't really need the Porsche 924 measure, that was done by the colleagues in 1977.

Gert Hack tested the 924 with five-speed gearbox in volume 23/1977 - a tester with excellent knowledge. To this day it is said about him - by no means wrongly - that he only has to park a car backwards in order to write a test report, more profound than anything that the rest of the auto journalists could manage. Of course, the Porsche 924 was up for collection back then the performance in Hockenheim on the forest straight. They do not exist anymore. But we don't let such insignificant imponderables spoil our history, we think. And call the forestry office.

Hockenheim was always a place where the fox and the rabbit said goodnight. Since the route renovation in 2002, they can also do this on the forest straight. Everything from the entrance to Parabolika to the end of the east curve has been demolished and renatured and is managed by the forestry department. The office allows us to drive and take photos on the piece between easternand Ayrton-Senna curve, only there the route was preserved. That's exactly where we always met. Back then - still with full hair and on Mondays around eleven.

Porsche 924 weighs 1,163 kilograms

On Monday at twelve we roll back to the 924 weighing hall behind the Sachskurve with freshly stripped cord jackets and bell-bottoms. A Hyundai i40 station wagon could be filled very completely with the old test equipment. Like every test car, we weigh the Porsche 924 without a load, but with a full tank, turn on the lighting on the weighing scale, which glows at 1,163 kilograms - 38 kilograms more than 38 years ago. This cannot be due to the feudal furnishings. Apart from the Targa roof, he only has one radio, and the pasha cushion can't weigh that much.

Then it's off to the pit lane for a souvenir photo under the podium. We invite the styrofoam cubes. Incidentally, 17 of them fit into the flat loading compartment of the Porsche 924 - that was once the equivalent of 192 liters by ams. With the 924, the testers used to speak of the 'overhead trunk' because the transaxle technology with the transmission is so high on the rear axle.

We are tinkering the Peiselerrad on the flank of the Porsche. Actually it is called a measuring wheel or an odometer. Peiseler Road Test Equipment GmbH in Groebenzell is the manufacturer of this calibrated 28-inch wheel for braking, acceleration and elasticity measurements. We suck it up on the flank of the Porsche 924, find the cables together. They all look very much the same, differ only minimally in the connections, but still crucial. Finally digits flicker across the display, the printer rattles measured values ​​on thermal paper.

Slalom on the bike path

We drive onto the empty track, accelerate a few times. The temperament of the 924 is on a par with today's cranked up small car. That was already a point of criticism of the Porsche 924 with the 125 hp two-liter engine, whose commercial vehicle background (VW LT) he was never forgiven. For the noise it makes - the old sound pressure meter shows 79 dB (A) at a speed of 160 - the Porsche should actually go better than the 204.5 (point five!) Km /h, which the colleagues once stopped as the top speed.

We drive behind the hairpin. An iron gate separates the ring from the old straight forest. Today it is a cycle path that leads 16 kilometers to Heidelberg and 1.5 to the east curve, overgrown by the forest behind a wall. The straight is narrow, a strip of green next to it, then the fir trees stretch left and right into the sky. In the past, it was almost too narrow between the guardrails in slalom. They no longer exist today, if we lost our way, we would immediately log into the forest. But we're only here for harmless photos, put pylons on the seam line in the middle - one every 18 meters. Then we dismantle the wheel and get the stopwatch. Even at a very slow pacethe rear of the Porsche 924 throws around in the slalom. The transition between oversteer and understeer, informs the old test, happens suddenly, which can be kept under control by quick counter-steering. Yes, you can.

Admittedly, by today's standards, the Porsche 924 is an astonishingly unambitious sports car, with wobbly handling, bulky steering and a dull engine. But until the night passes over the treetops, we drive on, stuttering brakes with a Peiselerrad to measure the deceleration, are happy about the 924. Because a Porsche that never had a great future in front of it, we should at least treat a glorified past.
