Nope, that's not out of line at all! Cam timing is a good example, my guess is the guys that have time to post on here don't know that much about cam timing. It takes a lot of understanding of basic engine operation and tuning to be able to know what cam timing really does and what it effects. That and a ton of experience actually changing it. On top of that, even if you have the knowledge and experience, half of what you know about cam timing gets thrown out the window when you're talking about Turbos and Direct Injection.
It's also the guys that DO understand that stuff I'm trying to get in here. I know they're out there, but I rarely if ever see any of those guys post on here. There's a ton more super knowledgeable guys on the other platforms, a lot of the problem is these LNF's just aren't that popular. Still, why don't we see Vince in here, or ZZP, DDM, Werks, Hahn, EIEIO or whoever? I know they read some of this stuff, quite honestly they'd be stupid not to. There is information here no matter how much you already know or think you know. How come they don't jump into some of the questions or discussions here? Do they just come here to see what we've figured out and not contribute anything back?
