Run away from that FB group as fast as possible. That group makes me embarrassed to be a coyote owner. If you want good info on that kit I'd go directly to the people that are making it work: Jon (slagburn), Larry (Stretchb), Sai, don't know if he is a member here.
Yea I understand, there are a whole lot of idiots on there for sure. I mean I don't know a lot, but I know more than a little. I research and research and research before I do anything, and install my own mods, so when seeing something I know a little about I tend to give my $0.02.
The argument started because there was a video of a stock pulley paxton vs a 6psi on3 kit only making 550rwhp. How he's only making 550rwhp is beyond me, unless his DA is terrible, it's tuned really safe, or the dyno was a thief (stealing dem hp #s lol). I do know he only had 47lb injectors though (whyyyy... lol). The paxton would pull ahead at start of the pull (think it was like 40mph pulls) and the on3 kept pulling up on him and getting by him right before they let off. The paxton doesn't have a big enough fuel system and runs out of fuel if he doesn't shift before 6500, so that's his excuse for the times the on3 pulled past him, and claiming once he gets his fuel system finished he'll have no problem... which is fine I guess, the on3 only has 550 rwhp... lol.
I was basically tagged and told "my paxton is going to beat your twin setup on stock block" so I had to dive in because I don't think that's true. To my knowledge twin turbo kits make more torque than a centri, are easier on the internals than any pullied-type of power adder, and therefore can make more power safer meaning that you can get more power out of a stock block with them. That's what I tried to explain. But lo and behold, once again the giant bitch that is logic just couldn't be seen by the centri fan boys. I like both setups, and originally wanted a centri for this car, but for the price of the centri I could have a decent twin setup, which is better, is my view of the matter.
I don't know why people take this hobby so serious, it's all for fun, and there's always someone faster lol.
