I have decided to spray my car for Friday nite street racing, I run every Friday and I am sick of going 12.0 or slower on hot humid nites, I ran 11.71 in cool spring weather but not since. Tonite I only managed 11.93 @ 116.9 with 1.71 60 foot.Our track is about 3-4 tenths slower than most so I ordered a dry kit from dyno tune in NE designed for the 03-04 svt it comes with 25,25,50hp nozzles and has been widely used successfully pre- maf, you can also get .042, .046, .052 or 80, 96 and 123hp nozzles which I have as well as an appointment on the dyno 10/4 at Kauffmans in Dillsburg, Pa. How much should I tune for and spray? I plan to go Ken Bell this winter but would like my stock short block to last another season, any thoughts?
