Shook the car down with the new power at Road Atlanta during Z Nats...
Couple of things:
-Car overheats after about 4-5 laps (air temps in the 80's). Temps come right back down in half a lap, but quickly heats back up.
-Need a catch on the back for crankcase blow bye. Quite a bit of oil out of there (just a breather on it currently).
-Need to finish the V3 front aero setup. Vette kicked up a big hunk of clay and took out the old bumper/splitter.
-The old pirelli's were scary as -uck. 25+ cycles on them now and they were terrifying. Had sticker A's mounted, but elected not to use them due to traffic and other issues.
-Low brake pads meant crap heat dissipation and quickly warming brakes. Had spares, but again traffic and time constraints (3 sessions in less than 2 hours in the afternoon) made me lazy.
Things in the work for the Nov 11-12 event at Summit Point (last event of the year):
-Finish front aero on V3
-Bought some fender vents for the front
-Replace front pads
-Oil catch set-up for the crankcase (parts already here)
My car is similar with heat issues. few laps and way up on temp.
Just fitted a new larger rad and new fan pack to help. Car is going on the dyne on the 28th for a map check then back on track asap to see if the upgrades have helped.
Last event at Summit went ok on Sat, some teething issues still (limited to 7-8 hot laps for the day). First lap on Sunday the hub failed catastrophically going into turn 1 (150mph), wheel wobbled enough to hit the brake bleeder, causing a leak and subsequently a fire. I got the car stopped, just enough brakes to slow it to within ~30mph of normal speed and just dorifto'd turn 1 without going off somehow. As soon as I got back to the pit lane the caliper seized and up in flames it went. Luckily I was right next to pit out and the crews were there in a jiffy to put it out.
Plans/Things to do before the first event (HOPEFULLY March VIR):
-V3 Front and new splitter/air dam/canards/etc -- Finally
-Shocks serviced
-Clean up the interior/paint cage/wiring
-See if I can get the tablet to work well enough as a dash/gauges
-Chassis mount wing/install carbon hatch
-Swap all the fluids out
-Isolate the rear wheels/make some rear bumper changes
-Rebuild front calipers
-Change out front hubs
-Maybe rear SPL knuckle bushings
I'm always moving around on spring rates. I actually run less rate right now than I did when autocrossing. Power doesn't really play into the spring rates other than it adds weight and with the higher top speed it requires a a little more ride hieght (since the car hunkers down more with the added 15mph on the top end).
Making some big revisions to the aero this winter, so I suspect I will go up a bit of spring as well.
