OK,
Drove it to work this morning. The trip is about 15 minutes, with one valley (up and down, moderate incline for about 1 min) and the rest pretty flat.
The head temp (monitored at #3 cyl) varied between 150 and 250 deg. It was a pretty relaxing drive, 80 kph (50mph) speed limit. Oil temp hit 180 deg (fan turned on) when I pulled into the parking lot.
I accelerated up the hill in 4th !
I'll have an even better idea of how this engine performs when I go the Boxer AG meeting this Wednesday. I'm taking the long way there, about a 30 minite drive and I'll get it up to 90 - 100 mph for sure !
BTW, I cooked a 165/80 on the weekend

.. had to buy some el-cheapo 195/65 's to get me by until I can put on my 18's.
The muffler is still a bit too loud on the car (Dynomax Super Turbo 2 1/2", like a Porsche / Corvette muffler, inlet and outlet on the same side, mounted like 1/2 of the BAS system .. STEALTH !
I will need to put some stereo sound insullation on the firewall in the passenger compartment. I LOVE the whine of the Porsche fan ... It makes me want to drive faster !
Later.
