May 10, 2009 - Another track day!
This time, the Targa car sat in the trailer and I drove Elvis, the LS1-powered bar (back in full health) instead. It took me some time to come to terms with the car. It simply seemed squirrely. Not so much under power - it behaved exactly as expected then - but during braking and cornering. It's the first time I've set up a car with this particular tire so that's part of it, and it has good brakes but without adjustment options.
But what I finally realized was going on was that I was expecting its cornering and braking ability to be in line with its acceleration ability. It thunders down the straight like the turbocharged Westfield beside it, but it still corners like a Miata and not a 1300 lb featherweight. So I had to bleed off more speed for the corners, and my Targa braking points didn't work because the car weighs 400 lbs more and was going considerably faster. So the problem wasn't the car's traction, it was simply that I was asking too much of it.
Of course, another problem was the red mist. My first session out, I'd blown away the fastest Miata to ever run the track. So I was hoping to beat the track record for Miatas by as much as possible. I did, by a considerable amount. And now that the mist has faded, I realize that I need to spend some time tuning this car on a big track, where I can get it settled on a long sweeper to set the basic handling balance and then tune the transitions from there. The car still handles well, I just want to bump it up to the top level. Not bad for a street car though.
I took Janel out for a few laps. She was impressed by the violence. It would be a very effective Targa car, but it would take a different driving style than the current setup. The fact that it was faster in street trim than the Targa car is in race trim is a good sign.
Janel also took her own car out for a couple of sessions. Now that she's experienced the Targa car at its best, she was quite adamant about the shortcomings of her previous ride. "I miss my tires! I want my brakes!", she informed me. Oh boy...
