The weather today was reasonable, so i decided to hit up the local test and tune for the first time of the year. Temps were in the mid 70s, humidity about 30%, but there was a 40mph headwind, which sucked. The track almost went down to 1/8th mile after a JR dragster tipped over at the 1/8th mile, but thankfully didnt.
I was running the car in my sig. I currently have no HPTuners cause it broke, so im running my rich/very safe 10psi tune from last year. Had it set up for wastgate boost only, about 7psi. I topped off with 89 octane, drove 60 miles to the track and went right to tech then staging. didnt let the car cool down and left my street tires on which are 255/60-15 firestone indy 500s. Proceeded to run:
60'-2.069
1/8th-8.08
mph-93.59
1/4-12.260
mph-116.41
This run i left at about 2400rpm, 3-4psi and it hooked good but didnt spool very well. I made 3 more runs on the street tires trying to hit them a little harder but just spun. This led to me putting the DRs on, BG 275/60-15. First run with these i did a small burnout and left reasonably soft, bout 2800 and 5psi and they hooked. Ran:
60'-1.80
1/4'11.59
mph- about 118
Forgot the timeslip in the car
Next run i didnt get into the tree fast enough and left soft again:
60'-1.821
1/8-7.522
mph-96.24
1/4-11.614
mph-118.54
After a hour cooldown the clouds were coming in and i went for one more. This run i launched as hard as i thought i could without the car rolling. My front brake pads are so glazed they dont hold very well. Launch was about 3200rpm, 6psi and it held:
60'-1.766
1/8-7.358
mph-97.65
1/4-11.425
mph-118.95

Some additional specs on the car, it was around 3780 raceweight today, stock body and full interior. Sub box in the back and everything, almost have the A/c back on too. Also it is more set up for driving with terrible front shocks and springs for drag, and full swaybars. I race it just as its driven every day. The engine has another 50-75hp in it on pumpgas, and i dont have an intercooler either. If i remember right these runs should be about 550-575 crank hp, the MPH isnt there because most racers were 4-5mph slower than normal in the wind. I think someone else got some other vids as well, i will post up if found.
