After a closer look at the screenshot:
How on earth is it possible to have only 670 PP with 1250HP on a car that weighs 1197 kg (and RM tires)???
I know it is an engine swap. But is that a bug in the PP calculation?
For future TTs i vote to ban engine swaps like NOS. Otherwise this becomes a chalange like 'who has the biggest unused engine in the garage'.
Nonetheless here's the actual stand of my search for speed in Tsukuba by classic tuning:
1st car was a Porsche Cayman GT4. Sadly, after adding RM tires, suspension, shedding weight and a gearbox, there wasn't much room do improve the powertrain. The Cayman is a dream to drive, but not very fast around this track. After a 55,971 i didn't saw much room to improve.
2nd car was a Ford Focus RS. Same way of tuning like the Cayman. Because of the AWD i did a 55,415, but it's not so nice to drive like the Cayman. And i don't see the potential to go sub 55 with me at the wheel.
3rd and current car is the Toyota Yaris 1st Edition RZ "High Performance"
That thing was a big surprise, not so much because of the speed, but the fun it was to drive! Sideways thru every turn an still beating the Cayman! I did lots of laps just for the joy of it - it felt like a tarmac rally stage.
In case someone wants to try it out, i'll share the setup i've used.
To get it faster around the lap i'm currently fine tuning the suspension, although i'm not a specialist for that. 55,319 is my best so far. I hope to get it under 55.
