This drastically effects power due to the extra fuel, the injector sprays longer. This also makes for a sloppier injection process as the pressure falls off. Also because of the extra fuel smoke and exhaust temperatures can grow exponentially. Delivery valves are awesome upgrades but the size of the valve again will be determined by its application. A lazer cut valve (???)
