How to: Truck Pull

[wuboring]

I got talked in to trying out my 08 PSD with spartan 275 auto trans at a truck pull..

any tips..

put it in drive?
4 hi or 4 low?

Should i concentrate on giving it hell or try to watch the egts?

any help would be nice so i dont launch it off into the crowd or leave my transmission scattered out on the dirt

4 hi, watch egts but expect them to get hot. Look for the best path on the track and keep momentum.

4 low, put it in drive and let it do its thing, if it starts boggin too much manually down shift it. Ease into the throttle to start with and once you get rolling giv'er hell. Pay no mind to EGT's, it will do nothing but scare you, just watch the track. Your EGT's may go over the "safe" limit, but its for such a short time it will not hurt anything.

should i hold the brake on and build boost before I take off

[Jake]

No, you might end up getting too much wheel spin to start with which will end up slowing you down overall and give you shorter distance.

Yes to an extent. You dont wanna just spin the tires off real easy tho. I still say 4hi, these trucks have plenty of torque to get the sled moving and you want momentum. I have gone to countless truck pulls and traveled with a local guy who pulled a cummins and everyone was always 4hi

just kidding, a friend told me 4 low also, so Im going to try that unless lots of people post up and say 4 hi... I think i wont build boost and just leave it in D and hope for the best.

ok, the only problem with that is easier wheel spin and running out of gear. If your worried that high range wont be enough power your nuts.

Im sure some guys who pull regularly will chime in.

With low range you can get moving faster. You wont run out of gear, i don't think you are gonna be going 40 MPH down the track pulling a sled.
