Here's a few bad laps at MSR-H CCW

I left time in a few places after looking at data, which I'm also new at. I can pick out at least 1-second in mistakes on my best lap, I pretty much struggled all weekend to get in front of the SM times, and finally did on the last session, which is pathetic and stupid. I need to really work on bringing the car down and trail braking from 5th gear speed, 4th gear trail braking is much easier. I'm also on 11-weekend old NT-01s so I didn't have the most grip in the world, but the tire was still pretty fast.

I want to compare with KenOhhhhhh, but my datalogger doesn't like to pair too easily and I'm new at this.

I was not consistent and it cost me 1st. Finished .129 out of the top spot. My best was a 1:43.2, theoretical was a 1:41.7. Not one lap were I had more than 2 sectors as the best.

Are there sposed to be linkies on this thread? Just saying.


Ok I see both now. That track looks odd in that direction.

Hey brg, if u don't mind how much power is that car putting down?

215whp for dumb NASA TTB. I'd rather run it at 250whp and drive like a man. The difference is that I'm only running the long-runners in the 99 plenum so it's making "trucker torque", lol.

You are absolutely crushing me in corner speed. Is there some kind of magic I'm missing where I'm not loading the car up properly, or is it tire that's giving you 8-11mph more speed in the carousel, 8mph in Diamond's Edge, 12mph in Key Hole, 5mph in Gut Check, and 10mph in sugar & Spice? At least I know I'm not too far off. Frankly, as much as I hate to say it, I don't think it's all tire. Tell me your secrets or I'll tackle you on your scooter.

I don't want to be competitive with power, I want grip!!! Maybe 10+ weekends on NT-01s is too much? I suppose you're also on a new 275 Hoosier and I'm on a "last day" 225 Nitto, lol.

Nice! Car is fast,

Thanks. It's pretty scary on 12psi with only makes 260whp.

New 275 R6s give you the hand of God grip. My M3 has many hours of setup on R6s to get it to this point.

How is your car setup? Alignment, shock settings, etc. The white M3 has a mirror setup to my car expect tire size. His times were very close to my times. I would guess you may have some settings that could be tweaked.

If you set a car up to run on Hoosiers, you need to run the car on Hoosiers. You cannot vary from your setup by too much or you will not see the same results as the original configuration. You need to have a setup for new tires, old tires, race tires, street tires.

Also on that lap the car was on the very edge of staying on the track. See last turn for a good example. But I know where that limit is and what the car feels like when it is about to let go. The longer wheel base gives me more notice over a Miata.

I suggest getting fresh tires. Setup for new to ok rubber. Spin the car or slide it to find the limit. Get a better data logger and see why you went faster or slower in a section. You seem to be moving the wheel a lot. Could be the crappy tires and fighting for grip.

I run the 949 alignment which makes the most grip of any I've run, the car feels balanced. I think that datalogger will be OK now that it's working. I am a bit more timid than you through the sweeper and through Gut Check, 106mph in my car through there was horrifying, I have no desire to do that again, lol. In the slower corners the tires are talking and I'm not fighting any under or oversteer; the car is set-up to turn on the gas pedal ever so slightly which is why I runner a bigger swaybar in the rear than most. I think this is set-up right because although I was throttle-obtuse in the carousel and Diamond's Edge, Bus Stop is neutral, and Keyhole is full-throttle 3rd gear with no oversteer. I really felt like that car was set-up right for this track from the seat, but there might be more time in Carousel with more rear grip...then I'll really have to cook the tires in the slow sections. I know I needed to open up the entry on Diamond's Edge, I was sketch every lap in Sugar & spice, my brain never made it that far down the track I guess

I want to get back there on new rubber and see what kind of numbers I put down. Thanks for talking about this with me.

When I get the van I may run two sets of tires so I have something to practice on and something for money. One can be a new set of NT-01, the other can be the old set. I had a tough time sustaining anything over 1g...I know that's not right for this car.

I want a trailer so I can do the same with tires. One set for the money, one set for practice.

When I get the van next month I bet I can find some space for them.

Just don't accept Ken O's payment terms in back of van.

Alignment specs from the internet are almost always going to be faster than the ones you find from testing, and frequent changes. ;)

Try new ones all the time, the stopwatch does not lie.

I've taken tire temps, the 949 settings work, and pretty much every fast car in the nation runs those settings with slight variation in rear tow and caster which I adjusted for personal preference. I remember when I switched to them for Hallett a couple years ago, suddenly seconds fell off the lap.

I'm glad my car is slow. Otherwise I'd run 949 settings.

A couple points of reference... Mr BRG is using ASTs on a Miata. The 949 Racing team just recently won their class at the NASA 25hrs of Thunderhill in a Miata on ASTs. Granted I'm just a bench racer here, but I would think that 949 alignment specs are at least a good place to start.

The way this car handles and the way it behaves intuitively is shocking. I'm happy I had the scratch to pick-up those shocks when I did...because I don't have it now, lol.
