Well I took my car to Milan Dragway yesterday to see what it would do. I had a blast and it didnt set the world on fire but I am real happy with its first outing!
My full build thread is here but here is a quick review. I rebuilt a 97 Explorer GT40P motor and only mods are a TFS1 cam,BBK long tubes and a PNP MS ecm. It has a t5,3.55 gears,cheap 17" street tires and a 2.5" Y-pipe into a single 3" exhaust.
Crazy to think how fast I put this car together and how well it turned out. I showed up at the track with all of 66 miles on the car. Brand new motor,new T5, new tires,new braking system,new suspension and a brand new MircoSquirt computer with very minimal tuning time on it.
First pass off the trailer went about how I thought... blew the tires off, pedal, short shift around 5500 and ran a 14.52 at 97

Logs showed it was real lean everywhere so I added some fuel and tried again. Still tryin to figure out the launch it went 14.00 @ 100 after a few horrible launches

Added more fuel and launched it real easy it pulled a 2.09 60ft and ran a 13.93 @ almost 102

After that there was a string of a few more 13.90s but with more wheel spin it wasnt going to get any better. I data logged every pass and made some adjustments this morning that really made a big difference in the seat of the pants.
My biggest problem is the car is right in the middle of the wrong gear combo. With 3.55 gears my shift light was coming on about 1000ft or so in 3rd and leaving it in 3rd I would cross the line doing 101-102 at 6200rpm, if I shifted to 4th it would drop 3mph. So I think I will work on the tune to find some more power and next time I go back try shifting to fourth early at like 5500 instead and see if it has the power and distance to recover and pick up some more mph.
