Well atleast I did a write up for the sake of my fellow cobalt members and not for the sake of making a buck. I did the same for carbon fiber and I make money off that. Then you come and talk down to me about my valve cover saying it's not right yet I've gotten othing but compliments here and at shows about it. Then when you tell us you have the magic secret like a typical internet douchebag you won't share it with us.
So there it is, typical internet garbage.
I'm not here to make money, I'm here to gain and share knowledge with people who are interested in the same thing I'm in. You know what? I've done a good job of that as well and for the hobbiest that doesn't have fancy tools my write up is great.
Go crawl back in your hole, YC doesn't need you.
