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. |

seems like maybe you’re playing it fairly safe on the curbs?

yeah sorry, my reference was for entrance and mid-corner
having never driven there I can’t say, but watching the vid it seemed like there might have been some time charging over them more. you should shoot for 13:1 AFR on a Renesis. . |

Virginia International Raceway (VIR) full course - 2:19:5 (2:19:0 theoretical without traffic)
2005 Base 6MT, Hotchkis Sways, Bilstein B12, Hypertech, HKS Hi-Power, Rota RT5 17x10, 255 Hankook RS3V2 (not very grippy...). 3070 pounds with 185 pound driver. low compression. video in youtube link in sig. 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. |
Here are a few PB as of current
LS swap Putnam Park 1:07.7 (this is my home track and as fast as I have heard of any production based car going) Gingerman 1:31.2 Mid Ohio 1:29.4 Grattan (only been there once) 1:22.9 Renesis Hoosiers Putnam Park 1:12.5 Gingerman 1:37 NCM 2:14.4 Road Atlanta (only been there once) 1:40.0 VIR (only been there once) 2:09.2 Renesis/200tw/Aero NCM 2:20.2 Tuner 4/STX 200tw NCM 2:23.4 Videos https://www.youtube.com/user/dallasreed/ Putnam Park lap: |

First time taking the RX-8 out on track. Fun Car!
Mid Ohio is always a good time, and had a great weekend in HPDE with Gridlife. Mid-Ohio, 1:44.60 2004 S1, 6 spd RacingBeat Header, HKS exhaust, LS coils, RacingBeat Revi Intake, AST 2 way coilovers, Kaaz diff, 245/45r17 Falken RT660 tires, ???brake pads(came with the car, no idea)?, Racetech seat on BuddyClub Low Max rails, Momo Steering wheel https://photos.grid.life/gridlife202...TQxMTQxOTkwNQ/ Video should start just before the start of the fast lap: |
