Talk is cheap, show me the numbers. At a 1/4mi track I'm guess you wouldnt pull better than a 14.4@96 And i am being very nice. Like golf dude said the s2000's are tricky cars to drive. Another case of driver beating Driver. Fastest stock 1/4mi run for a s2000 is a 13.7@10x.xx cant remember. Race a S2000 on the highway. Best stock 1/4mi time for a xf that i know of is 14.7@95 by i believe road and track in a 6-speed. I don't see how 15whp can knock off over a half a second. Only one guy that i know of has posted his stock 1/4mi time and he was running 15 flat @93ish. Its here on the forum.
