Crown Vic GT 5.0's With Thrush 2-Chambers (Speed Density vs Mass Air)
As of today September 6th 7:52 pm EST 2011 both Crown Vics are Mass Air cars equipped with A9P computers. This video was shot earlier in the day before I converted my homeboys Vic to Mass Air. You can hear the differences in idle quality between Speed Density and Mass Air cars if you know cars. I built both cars along with many other Box Panthers and I have successfully converted each and every one of them to Mustang .H.O engine specs or plus with GT40 or GT40P heads and Explorer intakes running either Speed Density or Mass Air Mustang computers
1997 Mercury Grand Marquis with 5-speed Manual Transmission, First Drive
A couple months ago, my friend Rob and I picked up a 1997 Mercury Grand Marquis with 66k miles for $350. It had a major coolant leak and had been neglected for a while, sitting in a cul de sac and covered in grime. We COULD have just fixed it and sold it and turned a quick profit of a grand or so but we did what any right-minded hooligan would do... we threw a 5-speed in it!
On the first test drive we hit the fuel cut off when the speedo hit 100 MPH but we were only going about 30-40 due to the difference in speed sensors. On this second test drive (but the first one where we could wind the car out) the speed sensor was disconnected.
The 5 speed Grand Marquis Project: Stock 4.6 liter v8, TR3650-5 speed from a 2006 Mustang GT, Fidanza alum flywheel, 05 v6 Mustang Driveshaft with an extra 7 inches TIG welded into it, fabbed hydraulic clutch, dual Flowmaster Exhaust.
A brake pedal from a Crown Victoria and this car's brake pedal were modified to fit next to each other and offer a natural driving position. We installed a generic master cylinder (attached with a bracket to the brake master) and a clutch line along the intake on the driver's side of the engine down the wiring loom on the passenger's side in order to plumb the slave cylinder and everything looks pretty much stock from under the hood!
The transmission tunnel had to be cut quite a bit in order to fit the linkages and levers from the newer transmission and they intrude into the passenger compartment. We're going to put some sound deadening down and secure it with the rear floor air blower ducting that has been modified to fit over the entire assembly. In the end, the carpet should install like it was from the factory with a small hole cut for the shifter and a small boot secured to the carpet.
With the stock 2.73 open differential this car is quite slow. That will be rectified in the next couple of weeks when we find a 3.55 LSD and drop it in. We'll also be getting rid of the pesky automatic shifter and button up a few issues with sensors and interior components after it's running and driving reliably. Oh yeah, the A/C blows cold also!
1990 and 1991 Mercury Grand Marquis LS comparison.
A comparison of a 1990 and 1991 Mercury Grand Marquis LS. The 90 is mine and has the upgraded interior and vinyl top. The 91 which has the standard interior belongs to my friend. Both are painted in the same light titanium colour with grey interior and grey vinyl tops. A look at the differences between the two and a look at the some of the options. One thing I did forget to mention was the 1990 has both driver and passenger power seats with dual manual recliners. The 1991 has a power drivers seat and a manual passenger seat. Sorry about some of the wind noise.
1996 Mercury Grand Marquis Turbo 13.2@104.77
I made it out to San Antonio Raceway, however I did not have a helmet, my plan was to do some test runs, however I got egged on by a Tundra and ended up hitting it pretty hard on the test run and ran a 13.2@104.77. I was unable to run again, I will be turning the Boost up this summer, we will see what it is capable of then...
BTW the Tundra ran a 15.1@90mph

V8 Aerostar ( 5.0 HO )
Ford should have made a V8 Aerostar. I got 5 mpg better than the 2.8L V6 5-spd, it sounds better, and its more fun to drive (power). Sitting 1 ½ inches lower with large swaybars made it handle like a car. I've had A LOT of fun with this van, now it's time for a change. If you ever get a chance to be part of the Hot Rod Power Tour I highly recommend it. It doesnt matter if you do the long haul or just one venue, you wont regret it or forget it!!!
