Then again, if you only remove it when you're autocrossing, you aren't
as likely to do as much damage per year. And a 3hp gain on a 48hp
engine is a 6.25% increase. Yes, I have proof. My dad had his Sprite
dyno'ed both ways when he was running in the sixties. The guys running
the dyno shop couldn't believe the difference. With things like K&N filters
available now, I'm not sure the difference today would be that dramatic.
