Hello.

What do you guys think about water/methanol injection as an antiknocking agent? Is there any point in adding it to a NA engine or is it only good for forced induction?

Since valvesprings might be the first things to give up at high rpm I would set the limit to 7700 rpm. Bisimoto said this is a limit they will handle.

Does anybody have any experience with Kospeed products? 1.75" seems a bit small, or is it okay/good? The price though seems awesome!
