I went out to Pacific raceways in Kent Wa. last night and had a blast! It was about 75 degrees out with some what cool air. The track had reasonably good prep, but I would spin like crazy if I just stabbed the throttle off the line.
I made 11 good runs, and only lost 3 races. One to a 96 GT Mustang (13.6) and another to a 6.0L tricked out GTO running low 12's at 111mph! and the last one to a 300M with a Hemi (not stock) 14.1@99 to my lame ass 14.43@98.3 do to a back to back run, plus I decided to take my girlfriend for a ride who added 205lbs (she's pregnant). I didn't spin but I only got a 2.3 60'. After that run, I kicked her butt out and did a 14.1@98.69 with a 2.2 60ft
My best run that night was a..........
13.96@99.51MPH with a lazy 2.084 60ft! My best 60ft was a 2.06.
This car is averaging 14.0's all day long 13.96, 14.01, 14.06, 14.09, 14.10. Not in order! The other runs were between 14.1-14.2 but I was spinning off the line or
waiting to long to shift .
The TMS only kicked in once and pissed me off.

Sitting in the staging lanes that night with the hood popped open would get a few people to stop in their tracks, I had this one kid in a Mustang who I raced (14.01 to his 14.04), come up to me to tel that he thought that I would be an easy kill! Another guy stopped to say "wow this thing has a V8?" Eve the Gto guy's were impressed. Their was a guy with an 05 5.7 GTO who couldn't even break a 14.2 he was hitting 98-99 all night I really wanted to race him!

I'm in the process of uploading a few videos so I'll post them later!!

I'm all stock at this point with only 2,007 miles

I'm going to the dyno (and not a dynojet) next Monday, a good Mustang dyno that you can roll with one finger.
I just bought the K&N CAI and a Hogan Performance http://hoganperformance.com/ (ask for anyone, esp. Curt who owns the place) 3" downpipe with res. delete and two polished st. steel Magnaflows. Gonna post stock dyno runs, then post runs after the install, and then after I get my computer done, I will post what that does. Look for it. Oh. were you on street tires or slicks?

Speednationís brand new, $40,000+ indoor dyno can do things that no other dyno can. The dual rollers require such little force to spin, you can turn all 4 rollers, as well as the giant PAU magnet and 350 lb. flywheel with just one finger!! Because of this, it can easily record accurate 0-60, 0-100 and 1/4 mile drag times. It will also do speedometer calibration, constant speed or constant force runs (to help diagnose problems that occur at a certain speed or load), plus more!! The dyno is also above ground so you can get underneath your car to diagnose vibrations in the drive train. The possibilities are endless!. One customer, after his first dyno run, removed his exhaust from the cat back (while still on the dyno) to see what gain in HP could be achieved)

Ha! My DIC displayed an average MPG of 18 flat. I went from 22.3 to 18 with 11 runs! Not bad! :drive:

Get some slicks and watch the diff. in your 0-60, 60ft. and 1/4 mile times, bro.

Good runs for completely stock. Mod that sucker CAI/Exhaust then mod the valvetrain (springs, push rods, rockers...), followed by some Drag Radials. Then get a tune!

Guy driving the GT350 def. did not know how to drive. Most of the 300hp Mustangs are running in the 13s. Good job and big win for us!!! Nice runs.
