I first went to nats in 2007. I got 5th in STS. The next year I got 4th in STS with no clean runs on day one. The next year I won STS. The next year (2010) I had a Toyo Tires contract and the R1R was just no good on an STR S2000 and I got 21 or something. Then I skipped 2011. In 2012 I got the 4th place spot in STR and was .051 back from first place.... yes, there were two guys between me and the winner. Last year, I got 7th in the Lotus with one year of development and on 225/245 tires. I'm not trying to brag, but I'm an alright driver.
yeah, that's pretty good! It looks you are a comparable datapoint. Any thoughts on the relative quality of your runs on the first year with the lotus? Do you feel like you left significant time out there?
I've never done any kind of data beside some MaxQ back in 2008 in my STS car. It was good for reminding myself that the tight line is usually faster. Past that, I didn't find much use for it. I'm also pretty skeptical of g force measurements.
Would I design anything from them as absolute numbers... not without a big safety factor! That said I do think that when they go up you are using achieving more grip and when they go down you are getting or using less grip, so they say something about how much one got out of the tires for a particular element run over run.
Here's an annoying piece of anecdotal evidence about weight: I often get a faster time with a passenger in my car. This shows that an extra 120-150lbs is often less of a factor than getting a run right when you only have 3 attempts.
Yes, I noticed this in my car too... though perhaps become somewhat less obvious since I stiffened the suspension, corner balanced and added the aero. I've wondered if it were real or just random chance. Might point to some need for weight redistribution... or it's just the effect of having someone there who will see it if you mess up
. Certainly driver skill is the biggest mod of all and trumps everything else.
I'm also not yet convinced that even at 2120lbs that 275s will be enough tire to play with the big dogs but I'm going to find out.
I'll be interested if you post/blog about how you modified the fenders for this. Also, what size wheel are you putting the 225 on? Are you running spacers? Do they rub... I've been running the 205/245, and I often feel like my tires don't heat up enough when high temps for the day are under 75. Pyrometer rarely reads as high as 115, though I always have to coast back for 15-30 sec.
Was amusing to see me with tire warmers and my opponent with a spray bottle in 65-70 degree weather last Oct.
oh, the huge cavity is obvious if you remove the aluminum panel that covers the sway bar. If you were creative, you could probably put 80lbs up there.
Ah, I've had the rear clam off but not the front... The condenser was removed when they did the oil line recall and the clam was already off for that.
