Finally got it. For those that remember this from a few years ago, there was a huge deal with a bunch of local guys. I made a statement about grand prix's being able to run 11's with $2k in mods. After lots of bashing by both parties, clubgp got involved, we had talked about making a bet, which never happened. But, I did however continue to get made fun of for that statement. So, I decided to pursue the 11's for $2k goal on my own. Anyway, here's the story....vids to come once I can get them off the cameras.
Took a day off work Friday, and went down to the drag strip in Tulsa. The gates opened at noon, and we were waiting in line at about 11:40. Once we got in, and unloaded the car, I took it through tech. That was the easiest tech I'd ever been through. Most cars didn't even need to pop their hoods. They had me pop mine as I was almost driving away.
Then, I came back to the pits and put the laptop in, and updated the tune. Went and made my first pass. I wanted to make an all motor pass, for two reasons. I wanted to see how big of a shot I would need to hit 11's, and also how this car compared to my old 97 that had pretty much the same setup.
So, the pass went as follows:
60ft: 1.888
1/8: 8.335
MPH: 83.69
1/4: 13.015
MPH: 104.57
I was pumped after this. That's .7 faster than the car ran last year on the motor. The DA was about 550' on this pass.
Got back to the pits and watched the video. I had a one wheel burnout, and still cut an awesome 60. So, on all the next passes, I took extra caution to get into the burnout box while going straight.
I took a look at the scan and shortly figured out why it went so fast....the car was crazy lean...upper 12's to low 13's afr. So, I added a bunch of fuel and jetted the car for a 75 shot.
I made another pass, this time with nitrous.
60ft: 1.822
1/8: 7.944
MPH: 86.3
1/4: 12.519
MPH: 108.52
The car felt great on the launch, but hit fuel cut when shifting into 2nd, like it did all last year. This caused me to see a 15* spike of KR on the 1-2 shift. The rest of the pass, the car was adding timing back. So, I spent some time looking at the tune. Sure enough, it looked like all the KR had come due to the fuel cut on the shift. I did what I could to firm up the shift, and remove some power during the shift. Then, looking at the scan a little closer, I found that it cut fuel at 6500 rpms. That didn't make sense because I knew the car was wanting to shift was above that. It shifted at 6400 on the "all motor" pass. So, after doing some more digging, I had the fuel cut set for 6500 rpms. Not sure how that happened, but I quickly moved it out to 7200 and got ready for another pass. My girlfriend also did some weight reduction by taking all the papers and stuff out of the door pockets. :biggrin:
So, spraying a 75 shot again, the car went:
60ft: 1.835
1/8: 7.839
MPH: 89.92
1/4: 12.235
MPH: 113.32
Basically the exact same time and MPH, and 60ft that I ran a year on in KC...but on a 125 shot down there.
So, went back to the pit's, pulled out the jets for the 125 shot, and made another pass:
60ft: 1.764 :wow:
1/8: 7.607
MPH: 93.19
1/4: 11.839
MPH: 116.46
The car felt waaaaaayyyyyy faster on that pass. I knew I had run 11's once I went through the traps....I was screaming like a little girl on Christmas morning. The DA was right around 1000' on this pass.
I was thinking about throwing in some bigger jets and seeing what it could hit, but daylight was running out, and I was tired of waiting the the staging lanes....the lines weren't that long, but it would take close to an hour before I would be able to make a pass. Kind of a joke.
But, the track was nice and sticky. So, very nice track....definitely some quick cars there, but they need to work on lining the cars up better.
And, entire performance mod list required to get the car to run like it did.
