HDA Posted January 14, 2013 Report Share Posted January 14, 2013 I guess we should start one here, shouldn't we? Date: 1/13/2013 Lap time: 2:40 Car: S2000 Estimated total vehicle weight with driver: 3000 Estimated wheel horsepower: 210 Top Speed: 130mph Tire size and model: 255/40R17 NT01 and old 235/40/17 Advan 032 Estimated ambient temperature: 55 and windy Note: Front tires 12 years old (not R compound) - Puffo Air Intake - Test pipe + OEM Exhaust - Koni + Ground Controls - Carbotech 10 A lot of understeer due to bad front tires. Last session of the day, I still have to upload the previous sessions so this is my prov. best lap. Pretty consistent 2.41s 2.42s Link to post
himself Posted January 14, 2013 Report Share Posted January 14, 2013 Might be an idea to combine the two threads. Or not. Date: 1/13/2013 Lap time: 2:33.x [2.32 with s/f at turn 11] Car: 996 GT3 Estimated total vehicle weight with driver: 3400 Crank horsepower: 380 [factory] Top Speed: Fast Tire size and model: Pirelli scrubs Estimated ambient temperature: 55 and windy Essentially stock 996 GT3 except for new springs. Video to come. Link to post

bigjae1976 Posted January 16, 2013 Report Share Posted January 16, 2013 Date: 1/12/2013 Lap time: 2:43.39 Car: 2011 BMW M3 Estimated total vehicle weight with driver: 3880 Estimated wheel horsepower: 350 Top Speed: 137mph Tire size and model: 275/35R18 Nitto NT01 Estimated ambient temperature: 60 and damp Mods: Dinan Stage II suspension, GC camber plates, Stoptech BBK, Dinan exhuast and pulleys. Notes: I have an EASY couple of seconds in the braking zones for T1/11/12. I know I can pickup some time between T9-11...need to stay in the gas. Need to play with the esses a little bit. http://www.youtube.com/watch?v=5LMSLBYrIAU Link to post
himself Posted January 16, 2013 Report Share Posted January 16, 2013 Interesting data bits [mph] - Forgive my math if I messed up. LAP = AVG MPH 2:20 = 87.4 mph 2:22 = 86.2 mph 2:25 = 84.4 mph 2:30 = 81.6 mph 2:35 = 79.0 mph 2:40 = 76.5 mph 2:40 lap is about 88% of a 2:20 [or 1.14 the other way] 2:30 lap is about 93% of 2:20 [or 1.07 the other way] You could read this as a car that runs a 2:40 is around 10% of a car runs 2:20. But the cost differential is probably way over 10%. Even though many people only got 4 sessions, almost all of them are still within 90% of their best lap time. Most of the advanced folks are closer to 95-97% of their best. That is, 3% of ~2:30 lap [AKA already got 97% of the track] is almost 5 seconds (or a 2:25 best time). 5% [95% of it] would be almost 8 seconds (around 2:22). 10% would be 15 seconds! [Miatas running close to 2:40 might only see 2:37-2:38, so they are already within 98%!] -td Link to post
robertcope Posted January 16, 2013 Report Share Posted January 16, 2013 [Miatas running close to 2:40 might only see 2:37-2:38, so they are already within 98%!] Very interesting stuff. Were there any Miatas in the 2:40s? I talked with a national champ SM driver about my video and Traqmate data, and he said that they had guessed they'd be in the 2:43-2:45 range based on watching the Ferrari Challenge, so my 2:44 was not a surprise to him. Personally, I think we'll be under 2:40 with a few more laps. I was a bit surprised to see something like a 2:22 lap from what seemed like an "okay driven" ZR1. HP matters at this track... obviously! robert Link to post
Dave Posted January 16, 2013 Report Share Posted January 16, 2013 I'm trying to understand this. A 2:20 is your "best lap" benchmark right? 90% of that is a 2:40. I'll be interested to see what the milestones end up being for this track. Mine is to beat @@bigjae1976 's 2:43. Ha ha!! Link to post
himself Posted January 16, 2013 Report Share Posted January 16, 2013 No way my car will make 2:20. Maybe a 2:25. :) I'd be happy with 2:25 in an old beater 996. I would say that most Red drivers should take their fast lap of the weekend and adjust it by .95 or .97 [1.07 | 1.14] and that's what they'll eventually see. If you ran a 2:40, that would be something like a 2:32-2:35. -td Link to post
Dave Posted January 16, 2013 Report Share Posted January 16, 2013 Ah ok, I misunderstood what you were saying then. Mine was a 2:46 before my session died with a dead Vette. I still think a 2:40 is a good goal for me to try and obtain. Link to post
HDA Posted January 16, 2013 Author Report Share Posted January 16, 2013 I think a 2.35 is well achievable in my S2000 setup, I'd just need more practice. I saw the video of the ZR1 doing 2.20.... Link to post
himself Posted January 16, 2013 Report Share Posted January 16, 2013 Indeed. Power really makes a huge difference on this track! Over 600 HP will do wonders for lap times... I saw the video of the ZR1 doing 2.20.... Link to post

I've got a spot reserved for Vettel in the unemployment line after I break his 1:39! Link to post

Alan Posted January 16, 2013 Report Share Posted January 16, 2013 Very interesting stuff. Were there any Miatas in the 2:40s? Brian ran a 2:48 Saturday afternoon in his SM. So I'd bet a nickle Brett was a couple seconds better than that Sunday in his SM on a better track. Brian's lap: http://www.youtube.com/watch?feature=player_embedded&v=y-WuMjzJ7V4 Link to post
bigjae1976 Posted January 17, 2013 Report Share Posted January 17, 2013 Fixed. So I've gotta find 1:07 now? No problem. Just give me another weekend there. Link to post
himself Posted January 17, 2013 Report Share Posted January 17, 2013 Finally got some video up. 2:33.x with actual start finish. 2:32.x using the green flag at turn 11. Ideal is 2:30.9x based on this data. I think 2:27 is doable with some additional laps. http://www.youtube.com/watch?v=JIOYPXYPyac Link to post

aveday Posted January 18, 2013 Report Share Posted January 18, 2013 As a reference, the Pirelli 911 GT3 cup support race on F1 weekend had the winner pulling the fastest race lap of 2:13.19 Source: http://www.wrightmotorsports.com/wright-motorsports-wins-us-grand-prix-pirelli-gt3-cup/ Of course that's a cup car... on slicks, but it sounded like the Pirelli's weren't the usual tire for those guys.

Max Posted January 21, 2013 Report Share Posted January 21, 2013 Date: 1/13/2013 Lap time: 2:22 Thanks for sharing the vid and awesome lap! Jeez- in 8 laps you would lap me- if I kept it together that long ;0 Link to post
metrocube Posted January 21, 2013 Report Share Posted January 21, 2013 I was expecting to see much higher top speeds from the horsepower cars, but it seems as if everyone was trying to keep a huge reserve. And that's 100% okay because I can relate to not wanting to be the person who blew through Turn 12 :-) Link to post
Quikag Posted February 1, 2013 Report Share Posted February 1, 2013 I was expecting to see much higher top speeds from the horsepower cars, but it seems as if everyone was trying to keep a huge reserve. And that's 100% okay because I can relate to not wanting to be the person who blew through Turn 12 :-) I did the pump pedal and open/close the bleed valve on my Motul flush. Long story short, I think a touch of air got in the lines as I was having to doublepump the pedal at the end of the two straights and even coming from turn 10 to 11. So, discretion was the better part of valor in this case and I was definitely leaving a bit on the table. I think if the stars aligned and I didn't care about possibly overcooking turn 12, I could have probably hit 170mph. However, since I needed to drive this car back to DFW, I took it pretty easy and left margin on the table. To this day, no one has ever paid me at the end of a track day or offered me a racing job. :) :) Really interested in seeing some strong lap times from the MVP guys this weekend. I tried to bribe my way into the event, to no avail. Link to post
