Ney sayers = realists.
"best " is subjective.Best for their application?Best for their plans?Best for their wallet?Best what?
Several of their claims about the system is utter BS.They claim more HP.More HP than what?A Motorcraft carb with 200,000 miles on it?Sure.But a properly sized & set up modern quad-NO.
Cylinder washdown?Again are they comparing this to a 200,000 miles Motorcraft carb?
The sales pitch wreaks of snake-
oil.But that's appropriate for a Shelby site.
