Well, last night I made a last minute decision to head up to Mason-Dixon Dragway this morning for some test and tune with the local Mustang club. The weather was great, and last time I tried to go the track was messed up so I didn't get to run on Mickey Thompson DR's on 16" CVPI rims.
But I was able to today.
I found a small problem though, with my 4.10 gears the MT DR's are much smaller in diameter than a stock tire. While I did not run out of gear, I did notice the shift points were off to much causing my times to not be the best. I'm going to need a track-tune to adjust shift points once I calculate my new rear-end ratio. (Probably more around 4.30 now...)
So...that cost me a bit of time. Also this was only my second real run on DR's having borrowed Merc's BFG's for 2 passes back in late March.
So I was really using the test and tune. Did 4 runs getting faster each time. On my 4th run I hit a 12.99@106.2mph.
I know I have more left once I get the shift points taken care of, and on that run my 60ft was a 1.880 so I know I have more left in the tire dept as well. They kept gripping - very happy with them. (255/50/16 MT DR's)
I was probably light on it out of the hole each run, as I only came to do a few runs. I was probably more cautious than needed when launching, I seemed to be afraid to ruin a run to a spin at the line. But I'm learning the tires so better times are on the horizon.
I think I used test and tune as I was supposed to - I learned my car more, practiced launching, tried different tire pressures, etc. My last few runs I was getting pretty consistent on the tree too with R/T on the last two runs of .030 and .098.
Merc joined me as a spectator and coach, was good having him there to get some pictures and video and I appreciate him coming out to support the only Marauder running in a sea of Mustangs and Lightnings. :)
So I know 12.99 isn't breaking new ground in Marauder-land, but for me it's my first run in the 12's and reaching it was a personal goal for the year - a goal I've now met.
I don't have many pics from the event (of my car) but I do have some videos unfortunately I can't caputre them off the camera until later as I need to leave in a few minutes for something else tonight.
But I'll get some vids linked soon.
Only two pics for now, I have more of other cars, the only pic of my car I have was from behind the grand stands - literally. :)
