TWS Setup / Best Lap TImes CW/CCW

Recommended Posts

yeah, sean's car is ridiculous. massive tires, awesome aero, good power, great driver. he should be our target.

He is in my class so he IS my target :) That is aiming pretty high but perhaps someday. It will take some tires, some car work, and most importantly some more skillz.

No idea which car, did not know he had two. The one I have seen is the medium blue one (smurf blue?).

umm, ok, so are you talking about his 350z maybe? cuz he does have a 300zx that's full race, gutted, 550+whp that's about that fast as well. but that car is brown.

not really aiming that high, we should be down there. don't forget colin ran a 1:56 on nt-01's in a mod. class Nb with 215-220whp! we should be alot faster than we are.

I finally broke 2 minutes today. I was instructing for Ride & Drive and asked really nicely if I could pretty please take the Boxsera out to tune the suspension a little. It was allowed and I went out with the intent to make some rebound tweaks.

 

Before the tweaks, I did a 2:01 followed by a faster 2:00.9 where I came into the pits. I'm analyzing the data now to make sure it was faster. Then I made some tire pressure adjustments, still nothing on the dampers, went out and did a 1:59! I reached one of my goals for the year, and the car isn't even optimal at this point. Over 125 on the straight. Best speed through 7 was about 102. I was doing little tweaks here and there with Jason Hough's help. Then, I blew out the collector on my headers. The car was done for the day. I think given the little tweaks we made, I have another 2 seconds to go. I'm looking forward to the next PDS/NASA/RPMS event there to reach that goal. I'm very happy with the results of today though.

 

Many thanks to Jason for at least taking a look at the collector and letting me know he couldn't do anything with it, and helping with the "feel" of the car. Also, mega-thanks to the manager at the Midas shop in College Station on the main drag there who did a quick weld for FREE!! on the collector to get it back together so I could get home to Austin with my eardrums not shattered. laugh.gif

 

I'm going to do some analysis of the data and see where I can get some time, and have a new goal for spring.

Congrats, very nice. Hopefully the weather holds this weekend and we can all try for some personal bests!

I haven't driven this direction since 9/2011, so it took a while to warm up. This is the first weekend with the MSM cam, not really sure if it helped much, but it didn't feel bad!

Well at the NARRA TT event this last weekend (Sept 22-23) I came very, very close to breaking into the 1:55 range on Sunday morning. I set a 1:56.07 CCW according to the AMB transponder official race times. This agrees closely with the Trackmaster time of a 1:56.10 for the same lap.

 

This lap was set on borrowed Hoosier R6 scrubs on TRM wheels with jacked-up suspension settings and me only pushing at 90% (because I did not want to trash borrowed tires). I think there was a 1:54 in the car easily, maybe a 1:53 with fresh tires, correct suspension settings, a little less wing, and pushing to 95-100%. A 1:56 was enough for 2nd place in NARRA TT-3, and some free Hoosiers (whoohoo!).

 

FWIW according to Trackmaster (5 Hz external GPS) I hit 148+ mph at the end of the front straight. That is about 8-9 mph faster than my previous best. Going into T1 at that speed... trying to threshold brake as late as I dare... is... interesting...

 

Two sessions later, when the track was heating up (and slowing down, everyone got slower) I replaced the loaner tires with 1 new and 3 well worn NT-01s on TRM wheels, took out some rear wing, and ran a 1:57.5. I was pushing pretty hard on this session since the tires were mine, and NT-01s are so much fun to push to the limit. The suspension settings were still jacked up.

My best guess...you're good for an easy sub 2 min if T14/15 wasn't damp all day.

 

I agree. I think if I had been out today, I'd be sub 2m easily. Heck, I might have been able to do it yesterday had I made another lap or two. T6 was still slick on the apex yesterday, and I messed up T10, and had to wait to get on the power into T14... those things add up!
