Help me out with my ET
I got a G-tech for Christmas today, and went out and made a run with it.
The run was a 15.66@91.9 mph and the 0-60 was 7.19 seconds. I couldn't make any more runs due to traffic....really suprised me how many people were out on a 2-lane road in the middle of nowhere on Christmas day..... A little slower than what i expected, but not too bad for a 4200 pound (with me in it) truck that has 3.07 gears. Now, isn't the mph a little high for the ET? I would like to have more like a 15.0-15.3 1/4 mile ET, and i think my truck is capable of that. I did spin for about 15-20 feet off the line, even with 275/60 tires and the highway gears. I shifted at about 5200 rpm. I was barley into 3rd gear when the 1/4 mile was over. My engine combo is a .060" over 350, about 9.7:1 compression, pocket ported 186 fuelie heads with 2.02/1.60 valves, 204/214, .420/.443 cam (bascially an old-shcool RV grind), 1-5/8" headers, 2-1/2" true duals with Flowmasters, Performer intake, stock HEI, and a 1406 carb jetted about 6% rich. My tranny is a completely stock TH350. Any suggestions for a low 15-second ET would be appreciated
