I'm torn over whether to disclose this idea or not...

I guess in the interest of promoting the art of racing I'll go ahead and share this idea. I'm sure I'm not the first to think of this, but I've never seen it discussed. We're about to remove the exhaust fan. Why? Well, let me ask you this; Why do we need it? We aren't really sanding anything, and as I see it, it's just offering resistance. Seeing how these races last all of 2.5-3 seconds every fraction of a second counts, and this part just isn't needed. The cover came off with four screws.
