Posi units worth........priceless........

Or a half of a second reduction in E.T. ! I just returned home after an afternoon of test and tune drag racin' at Sacramento Raceway. I was able to literally shave .51 of a second off of my previous best run of 16.15 seconds, my new best E.T. is 15.64 seconds. Most (if not all) of the gain was due to my much improved 60 ft time - it went from 2.4? seconds to 2.09 seconds. My mph did drop off some, from 91.38 to 86.27 but I suspect that is due in part to recent changes to the truck to make it a little more civilized.

When I installed the posi, I changed from 3.73's to 3.40's to help drop the RPM some for better freeway driving and I added power steering to help with parking lot maneuvers (now my wife CAN physically drive the truck). This makes it easier to justify spending some $ on it since it is now the 2nd automatic vehicle in our fleet of 6 cars/trucks and she refuses to drive a manual. That plus the truck was an absolute pig to try to steer in tight spaces.

Now, I realize that these are not stellar numbers compared to any other postings of late but the truck is improving none the less. I have gone much quicker and faster in the quarter in some of my other vehicles but none the less it was fun seeing what can be squeezed out of "recycled" parts on a shoestring budget.

While I was at the track I had the opportunity to meet a fellow board member, he goes by the name COUCH and pilots a primered black 69 stepside - nice guy with a rather unassuming looking ride. Unassuming that is until he ripped off a LOW 12 second run with a moderately warmed over 350 and a large dose of N2O - very impressive. All in all it was a good day spent with some friends doing one of my favorite aspects of this hobby - Drag Racing!
