So took the car to the dyno and it's dropping off at high rpm 8 9 k I heard so many things that will fix the issue some disagree some agree so I'm running it by the forum. I heard I need new retainers springs valves from a ap2 , cai , test pipe , I was also told it's a common issue and input guys? If you need more info let me know.

 

ok well you haven't even said what year/model (ap1 vs ap2) s2000 you have, so how do you expect to get any helpful information?

is it dropping off as most S' normally do, or is it a crazy drop?

 

Sorry for the lack of info 2002 s2000 ap1 "of course" N/A drop in k&n borla cat back other then bone stock

That looks normal.

 

from what I was told the drop off is to step it's not supposed to lose that much power in the 8 9k zone..........I have no idea like I said I showed it to many people and I hear different opinions it's fine leave it , or you need this and that , mind don't do that look im stock.

 

i just looked at about 10 diff n/a ap1 dynos, but the dyno operated stopped before 8k that day, was worried about redlining them

i think you are fine, if you want more power, get a tune
