INJECTOR SELECTION AND ATOMIZATION
Recently I have seen a lot of chatter about fuel injectors and who’s are better, up to and including a tuner that refuses to tune vehicles unless the customer buys specific injectors from the tuner. After stumbling on a post about this, I found it interesting that the tuner was making claims that, while having some technically correct parts, made it very clear that he didn’t understand what he was saying, claiming that unless people buy his injectors, the fuel will lose it’s atomization and pool in the port and on the valve, and be bad for performance....

As you increase in velocity, the length of … Continue reading Ported Exhaust Manifold Tech Info.
