Went to the track in Fayetteville, NC tonight. DA was 1000 ft +/-. Track was prepped more than well enough to hook my car.
Short Version
Ran a 13.25 @ 104.8 (previous best was 13.12 @ 104.8), even though the DA was over 1000 feet less and the transmission was shifting better (Jmod). I'm not really sure why such a big loss, but I'm thinking it was the track and I'm hoping to get back to the first track sometime soon to validate/invalidate these times.
Long Version
Best 1/4 ET slip:
RT: -.002
60': 2.03
330': 5.63
1/8 ET: 8.58
1/8 trap: 84.21
1/4 ET: 13.25
1/4 trap: 104.8
And this run really was a fluke. The next best 1/4 ET after that was a 13.30, and the next best trap was a 103.9. Best short time all night was a 2.00, but I'll get to that later.
So I was hoping for 12s, and thus I came away a little disappointed. As a refresher, last time I went to a 1/4 track (albeit a different one than tonight), I ran a 13.12 at 104.8, IIRC, (and lots of other 13.1-13.2 runs) with a 2500 feet density altitude and a really lazy shifting transmission (you saw the link in the other thread). I was really thinking that 1500 feet of density altitude, 18 psi in the drag radials instead of 35, and the Jmod would drop .12 seconds. Instead, it added it. Or at least something did.
I'm 90% sure that something is up with that track. We had about 10 guys from our club racing tonight, and not a single one (other than me actually) came within half a second of their previous best ET (I came within a couple of tenths), even though the DA was over 1000 feet better. Almost everyone was down 4-5 mph down, too, with a couple guys down as much as 7. Don't know what exactly, and maybe I'm just making excuses for my poor times, but I think something is up with the track. Any of you local guys have any experience there?
Short times. Well, at least I can say they were consistent. Every single one of my 10 runs was between 2.00 and 2.04. Why they are suddenly down a tenth from the 1.92-1.94 the last two times I been to the track, I do not know. I tried everything: more air pressure, less air pressure, higher launch rpm, lower launch rpm, leaving off of idle, you name it, nothing changed the short times a lick. It was dead hooking (and I mean dead hooking), and that was it. Foot on the brake, foot on the gas, lift left foot, drop right foot, and go. Nothing else to it. I have no clue why they are suddenly down a tenth of a second. I was thinking the cooler air might actually drop them a bit. I was wrong, apparently.
Good news is my RTs were great tonight. I red lighted on my best run by .002; my worst after that was a .09, and I had a whole slew of them less than .05.
Played around with the shifting settings in my programmer; nothing really changed anything there. It won't chirp the drag radials, but it does shift nice and firm.
I just don't know. Something is up, whether it be the car or the track. A 3500 pound, 300 rwhp car should run faster than 13.2. I really want to go back to Rockingham, and I am definitely going to before I give in and admit that it doesn't have a 12 second pass in it. But it has kinda got me a wondering. Sadly, the Rock doesn't have another test'n'tune until Halloween weekend, during which I'm sure they'll be packed.
All in all, it was still a fun night. There were a couple of GT500s, a couple of Terminators, a Bullitt, a 2011 V6, and about 5 GTs. So I got lots of spectator action. One of the Cobras actually had a Kenne Bell making 625 rwhp; I beat him....twice.... He was on itty, bitty street tires with no traction for the first half of the track. Treed him both times, as well. Trapping 125+ though...lol.
Alright. End novel. And I'm going to bed.
