The real question is, did the increase in power translate into quicker times at the track? You bet it did, as MILF went from a previous best of 12.66 at 107.73 mph to a stout 12.47 at 110.00 mph, and it did so in worse weather conditions. Without a doubt, Project MILF has a presence on the road, though it's still docile enough to haul the kids around. Maybe we should change the acronym for MILF from Mustang I'd Like to Flog to Mommy Is Lightning Fast.

Updated Household Budget
As We stated in our previous installments, we're keeping tabs on how much dough we are putting into Project MILF. After all, if we blow our paycheck on the car, how are we going to pay the mortgage? Keep in mind that this tally includes the cost of parts only. The original cost of the car and labor rates are not included, as there are variables to both figures.
Handling Pack FRPP {{{M}}}-2005-FR3 $1,299.00
Super Pack FRPP M-6066-M463V $4,899.00
Billet Oil Fill Cap FRPP M-6766-MP46 $ 44.00
Valve Covers FRPP M-6582-3VBLK $ 269.00
1 3/4-inch Long- Stainless Works M05H175 $1,542.40
Tube Headers
3-inch After-cat Stainless Works M05CB3 $ 880.{{{90}}}
Exhaust System
  Total: $8,943.30

Rolling Thunder
To Quantify how effective the long-tube headers and exhaust system were on Project MILF, we did a pair of before-and-after dyno pulls on Crazy Horse Racing's Dynojet chassis dyno. With the stock exhaust manifolds, cats, mufflers, and 211/42-inch exhaust tubing, the car pumped out 328.9 rwhp and 287.4 rwtq. After installing Stainless Works' 131/44-inch long-tube headers, high-flow cats and mufflers, and 3-inch pipe, MILF upped the power number slightly to 330.2 rwhp. The torque number saw a significant increase, as it moved to 304.8 lb-ft. If you do the math, that equates to a 1.3 rwhp and 17.4 rwtq increase.

The peak numbers do not tell the full story, however. If you look at the curves, the headers and exhaust system show an increase of both torque and power above the stock system starting at 4,200 rpm. This increase will help the car throughout the entire quarter-mile, and it's something you will definitely feel in the seat of your pants.

Now, you might be sitting there muttering to yourself, Didn't this car make 335 rwhp and 308 rwtq after the Whipple blower was put on? The answer is yes-and no. When the dyno tests were performed after the supercharger was on, compared to the runs made after the exhaust was installed, the air was much different. Cooler air makes more power, and that is what we had when we dyno'd the car with the blower. Even though the dyno compensates and corrects, it's a good idea to get a new baseline before each change. That's why we rebaselined MILF the day of the install. Nevertheless, the real dyno is the racetrack, so that's where we headed next.

Numbers, Numbers, Numbers
What would a MM&FF test be without some track times? After each install and subsequent dyno test, we rolled to Old Bridge Township Raceway Park in Englishtown, New Jersey, to gather some real-world track data. Consider this the start of the logbook. For the differences in e.t. and mph, the first number is the difference from the previous modification, and the second number is the difference overall from the baseline.
