For those with a '97 or earlier 4R70W should replace the outdated 1-2
Lincoln mark Viii top speed
Mark Viii, chipped, intake, no cats, glasspacks, ported polished heads,
interior fully gutted.
And catalytic converters are just some liberal bullshit. Thanks for viewing
Mark VIII attitude
A video stitched together of a few different shots that I have taken of the
Mark VIII in action. It's an attitude video. Some pretty good burnouts
and great rolling shots, if you are a fan of Mark VIIIs
2001 Ford Crown Victoria police interceptor Jmod 0-70
2001 CVPI After doing Jmod to the 4R70W transmission. im submiting this
video of what the results and gains were from it im not 100% sure but it
looks to me like i began accelerating at 0:51 and reached 70mph at 1:01 so
0-70 in 10 seconds maybe. not Super fast but works for me.
2003 Crown Victoria 0-120
Half throttle chrip, followed by 0-120, followed by a 2nd gear 50-80 pull.
2nd Cat delete, glasspacks tune and jmod
1998 Mustang GT J-mod
Just showing the shifts in a J-modded (Jerry modded) 98 GT. Car is
supercharged making 325 rwhp. Car shifts SO much better after the j-mod,
should have come like this from the factory.
1998 Mark VIII LSC 0-60 Revisited
Edmunds shows the 0-60 to be 7.1 secs when new.
Haha, upon further inspection I've realized that the last digit on the
counter is counting (non drop) frames, making the time actually 7.4x?
JMOD 2004 Mercury Grand Marquis LS (part1/2)
Just installed the jmod on my car this weekend and am very pleased with the
results! I left the accumulator springs in so the shifts feel more like a
snap of the finger rather then a punch. I think the shift responce is the
same either way. Leaving the springs in seems to be easier on the
transmission. (This video is driving through the subdivision)
2001 Crown Victoria JMOD
2001 Ford Crown Victoria, just a quick demonstration of the JMOD 1-2 shifts
under heavy throttle. A little wet outside this morning I spun into second
gear on the second pull and had to lift.
Car is mainly stock:
Flowmaster super 44 mufflers
ADTR P&P upper plenum
K&N drop in filter
