Of course you didn't choose SS, they don't do system for thoose cars, they are more on cheaper cars. For the top brands i'd go for Tubistyle, Larini or handmade systems by Bartoli.
Back IT, i followed the 'mods booked in' topic, it's very interesting. Can I ask you if you have a dyno of the same car before and after the
mod, the same day with the same temperature, and of course the same rolling road setup?
It's a matter of fact that the R56s have more hp than the specs say, i've seen some dyno over 180, and i'm confident this engine has a lot of potential.
Can i ask you why in the K&N dyno you used different Correction factors, specifically it says 2.89 and 2.61? The peak at 4300 rpm depends on the overboost funcion? It's a strange graph, more power at 4300 than at 6500? With the very flat torque of this engine it's really more realistic the first dyno of Power Engineering! I don't get it. power: torque*rpm...
I'm not trying to provoke anyone, i just to bring some light on the upgrades and the effect they have.
