From memory, I think you have captured the feeling of this place perfectly and I would say that the elevation changes are probably as accurate as one gets in GPL. I visited the circuit some time in the late 1980s, during the press launch of a new Saab. We were given a briefing about the circuit and then eight cars set off behind an instructor for a couple of laps at modest speeds. This was useful to learn the line. Then the instructor peeled off into the pits and we were off. I happened to be in the lead car.
The first bend that required really hard braking from our relatively slow start past the pits was Turn 7, that vicious downhill lefthander, with a rockface on the right and Armco on the left. I braked hard, at a point I had noted during the 'warmup' and expected to feel the pedal pulsing. It did not. Instead,the brakes locked. By the time my brain figured out what was happening, the car was completely sideways on the slightly damp surface. "What the **** are you doing?" asked an outraged voice from the passenger seat. "No ABS!" I shouted back.
The cars that we had driven to the circuit had ABS but it had been disconnected on the circuit cars. This had not been mentioned during the briefing! Somehow, I managed to avoid a huge accident. I did half a dozen laps and then pulled into the pits for my driving partner to have a go. I could not stop laughing when he spun at Turn 7 on his first lap.
I did quite a few more laps that day and I remember Ahvenisto as a fun track, if rather spooky - not one of the more accommodating circuits on which to crash, I should think.
Thank you for your excellent work.
[Edit] Why does it say "Jackie Ickx" on the left of this post?
