That's true but the varience won't be 5 points either. .3, yes, but 15.0 on a S1K is a lean recipe for losing power. Though if anyone can show me a graph where it's 15.0 across the board makes power over 13.8, for an example of lean but makes power, I'd like to see it.
We got some race results from a Motomillion sponsored racer Ryan Jones. He is running the XWorks flash, he got first place at Roebling in expert class.
I am sure we will have a lot more to updates from Ryan Jones.
Ryan is not a member on here but he has mentioned that the XWorks flash is one of the key factors to his success.
As you can see on the dyno graph posted, the mid range power is dramatically increased, but further more there are more advancements in terms of traction control and wheelie control when it comes to the XWorks flash, which makes all the difference on a road course.
You fellas or ladies do realize this is a na engine not heavily modified? 14.7 is stoic.
15 - 14 is fine for a na not heavily modified.
Now forced induction is a different story.
I'm sorry, but you're an idiot if you think that.
"A stoichiometric mixture unfortunately burns very hot and can damage engine components if the engine is placed under high load at this fuel–air mixture. Due to the high temperatures at this mixture, detonation of the fuel–air mix while approaching or shortly after maximum cylinder pressure is possible under high load (referred to as knocking or pinging), specifically a "pre-detonation" event in the context of a spark-ignition engine model. Such detonation can cause serious engine damage as the uncontrolled burning of the fuel air mix can create very high pressures in the cylinder. As a consequence, stoichiometric mixtures are only used under light to low-moderate load conditions. For acceleration and high load conditions, a richer mixture (lower air–fuel ratio) is used to produce cooler combustion products and thereby prevent detonation and overheating of the cylinder head."
I don't know about you but I ride under "high load" on my bike.
