1/4 mile track progress(always updated)
NEW TIMES UPDATED 5-16-08, see below
This time around, Ive taken it slower on getting parts. My last PI car, it was harder to tell what parts were really helping me, since I was adding so many parts at a time. Throughout my build, I will be periodically undating my times as I do different mods to my car. The car is a 1997 mustang gt with an esimated 150, 000 miles on it.
Id like to do this so others can see how much these parts actually helped me in a real world situation, not just a dyno. If anybody can calculate the actual density altitude of the days somehow, let me know. That would be a great addition.

This was the first time to the track with this car. Ive heard horrible things about SAR not hooking, but had never experienced it. Slipping the clutch, launching low, launching high, didnt matter, the track wasnt hooking for anybody. Cars with slicks were spinning half way down the track. Def. was my last experience there.

So I gained a full mph, and picked up .45 overall et. I know realize the car needs a gear. I made a bunch of passes, launching at 5000-6000 thousand. The car bogged hard at 11psi. I upped the presure a bit, got a tiny bit of wheel spin, which is ok, but no overall gain in my 60 foot.

A little cooldown on the car instead of hotlapping

(Maddox, if I sent you the entire run in a pm, can you post it? I dont have the timeslip or the message anymore)
I was hoping for a full tenth with the addition of the skinnies up front. Still having trouble powering the car out of the whole, not enough gear or hp to launch very well.

Tonight was a new best, same stock clutch, 2.73 gears, and a little more HP. Last run, the stock clutch let go. Its basically butter. Crazy that in one single pass, it went from normal, to gone. The car drove home fine, but I didnt want to make anymore passes.
I ran the 17 inch drag radials at 11.5 psi. I launched at 5500-6000rpm every run. The car didnt really bog at all, nor did it spin too much. I feel this was fairly accurate.
Too bad the clutch let go, I really though the 8.7x pass was coming. I just couldn't do it with the clutch feeling like butter, and being 40 miles from the house.
same mods, as above, nothing else done 5-16-08

I also need to fix my lovely check engine light, though that'll be a simple fix with some electrical tape
