It takes big gears for 1/8 mile. I ran some 6:32's rear gears in my 66 Mustang. Loved the handy cap against hot cars

 

wow this is a good thread. Im glad were talking about the good side of the psd 6.0. took my buddy for a spin today ,set my edge programmer on 4 ...he was grabbin the oh sh....t handle the hole way
well gotta go going skiing up in wyoming for the next 3 days

 

Me too, you launch.....they wait....and wait......and wait.....then launch..and red light! What fun!

 

what kinda times in the 1/4 mile do people put down with the 100 hp setting on the preditor programmer Im buying one tomarrow im just wondering I have a crew cab f-250 35 inch tires and 4" skyjacker lift kit and mac cold air

 

If you can find one of those race simulators you can input the data. Mine made 387 HP and 728 FT lb torque at the wheels. Look on my gallery for the graph.

The Motorplex is closed until July for renovation or I would be able to tell you.

 

I ran 95.38 So the speed limiter had already started to kick in. If i had a bypass i am sure it would be a 13.5 or lower truck.

Does anyone know if there is a trans controler with speed delimiter yet. I know the banks sys. controles shifts and bd make a speed delimiter @130mph but none that combine both!!!

 

Most tunners will do this

 

Mine ran 126 at 3600 RPM on the dyno. The Predator kills the speed limiter.

 

fast f350: Did you run in 4wd all the way down the track? Do you have an aftermarket exhaust? Air Filter? 1.77 60 ft. is moving.

 

1.77 can probably ONLY be attained in these beast with 4x4...
otherwise you're doing what Bob did in 4x2 just spinning most of the way!
and you can try to switch it off mid track, but it probably won't go out of 4x4 until u let off... and who wants to do that in a drag race :-)

I tried both ways in mine and didn't notice a significant differance that couldn't be attributed to other factors...

 

dont these trucks get squirrelly when u lift off the throttle at the traps? in 4x4 i mean. ive heard dodges do

 

Mine is a 4X2 and it is rock solid at 115. It feels more stable than my Mustang

 

my bronco tries to throw the right rear tire off the road when i let off in 4 dig. it has lockers 4.56s and 40s, but ive felt this in alot of 4x4s when driving in 4 dig. this is my major concern w/ taking my 9200lb 55,000 dollar truck up to 95mph in 4x4 just to slam the brakes and run it down the wall!

call me a weenie, but i just havent seen anything like it before.
i rode in a 90 mustang w/ a paxton and a bunch of mods, he ran mid 11s all day, i cant imagine that feeling in a truck!!! it is my understanding that some of these trucks r even faster than that? maybe not on this forum, but at these drags

 

Lockers will cause that.

 

Don't know about all the rest of the trucks in the world...
but my 6.0 was rock solid when I let off @ the end of a 4x4 WOT 1/8th mile...
Reaction 1.286 ( Disgusting !)
60 ft - 2.30
330 - 6.23
1/8 - 9.58 @ 73.29....

And I think with a little practice I can do better than this...
I now know that I didn't get the boost up enough to really launch properly...
it was quick, but not as quick as I've heard some do in these... like 1.7x 60 foot ...

Actually, it wasn't much different than what I do on the streets of DFW most of the time :-)
Someone I spoke to later commented about my driving in the left lane in the 1/8th with my elbow on the window edge and resting my head in my hand I was so relaxed !!!
