Lap Times
#226
Finally beat the time I set back in 2016 :-)
Laguna Seca - 1:43.41 -- blu3dragon -- RX-8 S1, fresh rebuild and ~2950 lbs w/driver. S2 transmission & Diff. Race seat, harness & roll bar. APR wing & small DIY splitter, Fatcat coilovers, Toyo RR 255/40/17 tires (not fresh, but can't complain with the time).
This track seems completely dominated by power to weight and I think there were 2 or 3 seconds in the fresh rebuild over my previous couple of outings which were set with the same car but an old motor.

I missed the apex of t5 just slightly and I was slightly conscious of not wanting to put any wheels off, but otherwise I think this is a pretty clean lap. Of course there are always areas to improve... Maybe on entry curbs? There's a compromise there as they are so aggressive it can upset the car a little on braking and turn in.

Anyway, to get back on topic.
VIR laps. A 2:11.2 followed up by what was on pace for a 2:10.9 or so.

I noticed this post when researching info on engine compression relative to actual power. In your experience how does low engine compression affect your lap times? Do you see lower top speed on the straights? Can you estimate how much of a performance hit there is on track given a specific compression loss. Like say is a 10 psi average loss worth 5 mph on the long straight of your favorite track?
Also what point of lost compression or track performance do you consider an engine refresh?
Thanks,

Audio is wind noise because GoPro is not good. Ran a 1:33.6 last night at NJMP Thunderbolt during TNiA. Running Nankang CR-1s instead of Yoko A052s, but no setup changes from autocross.

So I just did my first timing at gratten or ever for that matter. Cold wet day to start track was bit slick and definitely not my fastest time.
131.36
racing beat shocks
ebc rotors with cobalt friction pads front rear
falcon 245/40 rt660 with last bit of life on them.
2010 stock sport
pretty sure I can get under 130 if it want wet rained till 1pm.
I may try and get back in a few weeks. Track will be cold but better than last week.
