remeber they made that HP on a bone stock Ford 5.0 from a lincoln.. this is not a race built engine at all, no headers, no high compresion pistons, just a stock motor with this intake technology....Good luck reaching that level of power bolting on just a set of aftermarket heads onto a stock 5.0..

I am unsure where this technology is headed, Coates holds all the patents on it and likely wants some huge money to allow any of the big guns to use it..... I myself wouldn't so quick to write it off, as you have to remeber the testing was done with first prototype heads, not with heads that were developed for racing.... being able to almost double the engines power output and nearly triple its RPM range is nothing to sneeze at..especially considering they are a first generation test head...with proper development this system would by far exceed what they currently are doing...You shouldn't be so quick to write off new technology, as you really don't know anything about it, its limitations or its advantages..... As i say your not going to bolt on a set of aftermerket heads on a bone stock Ford 5.0 from a Lincoln and hit that kind of power, sorry but its not going to happen......I know you can build an engine to hit that power, but this was done on a fully stock Lincoln engine, full emissions, stock pistons, stock exhaust, everything the way it comes from Ford....that is nearly a 100% increase in power and nearly triple the effective RPM ranage.... find me a set of aftermerket heads that can do that please..... then keep in mind this was done on a first generation head LOL you guys seriously crack me up !
