I figure most of you have read already about the car but if not here's a refresher:

2011, 5.0. 300a package with 3.73 gears/limited slip. Weight with a full tank of gas and driver, 3792 pounds.

Stock tires/wheels/brakes. Stock tune.

The car base lined with dealer installed 87 octane at only 311 whp on our Mustang Dyno. We added 93 to a 1/4 tank of 87 that was left and gained nearly 30 whp.

Friday I built a set of offroad pipes for the car that gained 8 whp at the very top of the dyno pull. I also modified the grill of the car so the air was forced into the air inlet and built a carbon fiber divider to route the air into the inlet, this gained 4 whp with a fan blowing air into the air box.

Final dyno results, 348 whp.

First pass today I ran a 13.10 @ 111.09 mph, 2.0 sixty foot. Let me get this out of the way, I suck driving a manual trans car at the drag strip. My next 6 passes ranged from 13.1's to 13.4's. I thought I was having a problem with the drive by wire as the car didn't feel right after a hard shift, I assumed it was in the programming. Then on one of the passes the clutch pedal stuck to the floor on the 1-2 shift. Another guy at the track with a nearly identical 5.0 to mine told me to remove the assist spring on the clutch pedal (I forgot your name, so please remind me, but THANK YOU FOR THE ADVISE!!!) I pulled the spring out and the car was 100% noticeably different on every gear change. Still, 13.1 was all I could manage.

A friend of mine who is a hell of a driver was there, Trent, and I asked if he'd give the car a try as I wasn't happy with my driving. First pass he got in the car he pulled off a 12.77 at 111.30 mph, 1.94 sixty foot. Then a 12.73 and a 12.79. I knew he could manage a 12.6 out of the car so we let it cool off for a bit and he jumped back in it. Sure enough, 12.65, 1.89 sixty foot time. The best MPH of the day from Trent was a 113.02 mph.

Here are the best incremental times of the day:

1.897 sixty foot
5.39 330'
8.25 1/8th mile
87.33 mph 1/8th mile
10.63 1000'
12.65 1/4
113.02 1/4 mph

I'm happy with the performance and there are some things to consider. The car is FLAT OUT OUT OF RPM and is on the rev limiter nosed over about 40' before the finish line. You may as well lift off the throttle and coast because it does it on it's own when it hits the rev limiter.

The car noses over and slows down because it's out of RPM in 4th. A tune JUST to bump the rev limiter would easily drop the ET and raise the MPH a good margin.

The car had about a 1/2 tank of fuel, nothing was removed from the car, I actually had 10 pounds or so of extra crap in it.

In stock form with 3.73 gears I feel the car is just about maxed out as it comes from the factory. Shifting to 5th killed the car, so that's out of the question. A different gear, taller tire or a tune seems to be essential to gain much more.

I'd like to get the entire exhaust taken care of and tested on the car this week, the tune in it, tires on the rear and return to the track. Seems like a no brainer to get one in the 11's at this point but I guess I'll find out soon enough.

BTW, the nice guy who helped me out with the advise on the clutch pedal was telling me he installed a Steeda cold air kit, on his dyno the car gained 3 whp. I was happy to hear that and happy with the results of just modifying the inlet in the grill on our car.

Thanks for reading. Let me know what you think.

I suppose after this round of testing and 1/4 mile results get done it will get turbocharged.
