I run 15 -18 lbs (hot) on my import and it has the 265 45. others were never going that low but then again I got 1.78 60ft with street tires and video to boot!I believe around 20lbs would be a start plus take measure after a run cause you do heat them up and it changes(increases).

at what point do you turn on the overdrive again?

It doesn't really. You never get out of 3rd gear in a quarter mile run.
Unless you're "peddling" your competition.

Anyone know tire pressures for Mickey Thompson's?? or if there's just a general pressue used for radials?

The whole trick to great traction is experimenting. With my 16x9.5" slicks, i run 27# of pressure because they are narrow and it takes that much to hold the truck up. My Hoosiers recommend 20#. I have messed with the pressure and found this to be good to start with till my tires heat up. Then I usually have to let out some. Just try different pressures till you get the "hook" you're looking for. A lot of people tell you run 15#, run 17# run this run that...run what works. Every track is different every pass. That's part of the fun of drag racing. Just be careful running LOW pressure, if it gets squirrely when you get off the gas it's too low. BTW 25# turned out to be the best that day..

agree with Fep...I was running 30, then 27, the 22 at the shootout. Just keep playing with it until you dial it in. BTW I was still spinning down the track with 22.

So if anyone thinks that 13.99 is unthinkable with that setup????? Come talk to me in a week.

Did you have a tune for this 14.0 run??

this thread is over 3 years old. Crockett still has his truck last I talked with him, but he hasn't posted in ages

batrup99jeremy · 06-15-2009, 06:15 PM

ok thanks harley356

batrup99jeremy · 07-25-2009, 01:01 PM

hey guys i have a question about removing the tailgate for the track.. I did a brief search but didn't find anything. I have heard alot of people say different things either leave tailgate up or put it down or take if off...
well what works the best??
I also have a soft bed cover so no weight there really.

Harley#356 · 07-25-2009, 08:10 PM

if you have a soft bedcover without a doubt leave the tailgate up. It's debatable whether to leave it down or up without a cover. The aerodynamics of a truck with the tailgate up create a wind pocket in the bed that makes it more aerodynamic at high speeds with it up, but at lower speeds it is a big drag wing till you hit that magical speed where it helps.

But with a soft cover leave it closed. If you do pull it off though, you'll save 55 lbs, and every 100 lbs is worth roughly 1/10th in the 1/4. Add a hitch (~40 lbs) and a spare (~65 lbs) and you've got around 150 lbs off the rear.

Basically you just have to mess around with it and see what the truck likes. If you can get traction, pull some weight. If it starts to spin real bad and you can't offset it with tire presssure, etc. then add a little weight back on over the rear and it may help ya out.

ok thanks! i think i'll just leave it alone.... maybe pull it all off for a trip to the track
