Hi guys,
I'm up here in Alaska for my summer vacation as usual. Just drove through Palmer today taking my daughter to airport... would love to head back up there for the event, but not sure. My truck is down about 5psi boost after my trip from Illinois pulling 15K, so am working on finding the culprit... hope it's not the VP44.
Anyway, I launch in 4wd, and have broken the stock output shaft somewhere between 20-30 psi boost. Also have broken the input shaft, which is now billet! Of course, boost numbers may mean different "torque on shaft" numbers for different trucks. I was making about 40 psi max, but only 35 now.
Even if conservative with launch boost, 4wd is the way to go! You can kick it out under full power right away after launch.
Does Palmer have a regular drag strip?
