Vp fuels c12

[N3WMAN]

Some people confuse throttle response for power. I noticed my 93 civic had better throttle response when I used 91. Race fuel in a bike CAN do the same.

That's pretty much all I got out of running C12. Bike didn't seem any quicker, but the throttle response seemed better. Only tried it because it was free and thus hadn't tuned for it.

Same experience here.

That was probably the oxygenating agent in the race fuel.
They stopped using MTBE as an oxygenating agent and started using ethanol. Ethanol sucks as an oxygenating agent.
