Yeah, but you're listening to the cockpit sound of two cars at the same time. If your friends are anything like mine, they like to race identical cars. That makes it really hard to just listen to the engine.
Have you seen the tackometer in an S2000? It's pretty much the same deal, except it's HUGE and goes all the way across the instrument pannel. I guess it has a little curve to it as well.
