Also I sent you a link to the book face FuelTech tech group. Lots of helpful people. The forum owners obviously don't want to support FuelTech so it's better to look for resources elsewhere. The Australian RX7 forums have more info, no pistons has some. If this forum won't make a FuelTech section, go elsewhere for the info.

Now for my rant:

Apparently, rx7club wants FuelTech to pay for their own subforum. They say giving us a subforum for user support equals free advertising for FuelTech. This means they care more about advertising money than supporting our cars. They don't think the web traffic from supporting FT will offset what they can charge FT. RX7Club is a business that doesn't actually care about supporting its users or our cars. They are here for money, nothing more, nothing less.
