The D-Production version of the 924 was a factory kit that made the 924 into an SCCA D-Production monster. Al Holbert, Doc Bundy and others campaigned these cars in the early 80’s at SCCA events all over the country.
This stuff is definitely NOT Armor-All or anything like that. I have used those products for years, and they look good for a few minutes, then the shine goes away. PTR is magic…if used properly. Here is an example using an old bumper rubber.
Acknowledging that the 924 doesn’t get a lot of love from the Porsche purists, he also mentions that the early cars were not “especially powerful.”
Over 170 drivers and instructors registered to practice their skills at Sebring on the 3.74 mile seventeen-turn road course. Several 944’s showed up to navigate the same course that hosts the 12-hour IMSA race each March. The place bleeds motorsports history.
So in searching the internet for nuggets of 944 information, I stumble across forum posts where people talk about 1) the low power output of the 944 8v engine, 2) the desires to install forced induction and 3) the desire to dump their 944 Turbo due to high maintenance costs.
