I've had a dyno for 20 years, and I'll tell you now, that its not everything. Big peak numbers mean very little if the area under the curve sucks. I grade my engines on average TQ and HP under the curve, rather than peak power. To most shops, the worst tool they can buy is a dyno, because they start shooting for big peak numbers, and to achieve them, they'll leave everything else on the table and not even know it.
As technology gets better and better, people get dumber and dumber, and put our less and less. The art of engine building is one of the last true mechanical challenges left, and while technology can be employed to make a better engine, the human brain must stay engaged at all times.
Yes, thats my 308 GTS
i in my last post. I also have a 512TR. In the first pic you can see the Weissach brown 911 SC that used to belong to rfuerst911sc :-)
I also do ferrari work, but only when someone wants to think way outside the box.
