What is the most powerful NA S2000 on Pump Gas
#25
the itbs are jenvey..i think that kinsler will be better for top power.the cams yes are very hepfull but i had dyno the bc stage 2 and there was not too much diffrent.. i have no problem with itbs .now i have make and a custom plenum.they work perfect.

If I am understanding this correctly there are three different types of ratings. RON (Research Octane Number), MON (Motor Octane Number), and AKI (Anti-Knock Index) also known as PON (Pump Octane Number).
The rating used in Europe is RON and that would be the following values you provided
95
97
99
101
The rating that shows how fuel behaves when under load is the MON and are the following corresponding values
87
89
91
93
The rating for USA gas is AKI also known as PON and is determined by taking RON+MON and then dividing them by 2 and are shown below.
95 + 87 = 182 182 / 2 = 91
97 + 89 = 186 186 / 2 = 93
99 + 91 = 190 190 / 2 = 95
101 + 93 = 194 194 / 2 = 97
So in conclusion your 100 oct in euro would be closer to a 96 octane equivalent in the USA and if you did your dyno using a 97 it would be like our 93. Either way doesn't really matter because unless all cars all done on the exact same dyno/weather conditions (temperture and humidity and elevation)/tuner there's now 100% way to compare.
Did you notice a powerloss making a manifold for your ITB's?

thanks for all that help..
the car has the same power when it's cold and when it's warm...
the air/fuel it's the same exept low speed that I think that I lost a very small ammount of power.. the a/f was 13,2:1 and made 12,9:1 -13,1:1. 3000-5000 rpm
