It's all about finding a compromise, IMO. More power needs more fuel and more brakes. Probably more weight and of course more tyre wear.........
First thing I will be doing when time permits is to put Tango on a local rolling road and see what figures are. Luckily the guy that runs it was bought up in the era of K-Jetronic so knows all the ins and outs!
Although like a lot of people I dream of all the different (and mostly quicker) cars that could do the 360 in, when it comes down to it, given reliability, a 924 gives very good VFM and is a hoot to drive. So with a fair wind etc., expect to see Tango on the grid again next year. Maybe we can eek out a few more horses on the RR and knock a couple of seconds off a lap........
