ok.. the 1.5-2 sec was an exaggeration to express the point of s2k.. but it does lose a minimum of a full second by not launching.. when i say not launching, i mean about 8k.. not 4k..
what is this ask anyone thing? s2k isn't your typical everyday auto-x car that launches the same as all the others out there.. i normally launch around 2500 to 3k on almost all cars.. i don't know what cars you've competed with, but i know s2k isn't one of them or else you would have never said 4k launch was ok..

not all courses require a launch. there are some courses that start with a right/left hand turn where you can get away with not losing too much time.. but you WILL lose some.. every hundredth counts already, you'll lose tenths.. but 60% of our courses start with a straight or a slight curve.. the nationals this year had the north course with a somewhat slight angle, and the south had a right hand turn.. i know who jason is, and you should ask him.. even for the courses with a right hand turn at 10 ft. he launches over 6k rpm.. you can even ask ian stewart who ran the s2k last year and took 3rd.. (or was it 2nd?.. i'm pretty sure 3rd.)

..p.s. i was running an asp s2k with 275 rear tires.. even on stock wheels with street tires, a 6k launch will yield nothing.

*additional unrelavent fact: on any course that starts with a straight, you'll lose a second if you don't launch in an evo..
