I can remember ian Howell built his evo engine and he purchased a ams inlet manifold and he did some sums and he reckoned that there was no way would it produce the numbers in a responsive track engine. He called ams up and they said it will Defo do over 1000bhp without a problem when you run 60 psi through it lol , what mugs gonna do that without billet blocks etc , just crazy.
but there is some very powerful cars without a doubt as they simply would get the times or speed they get .
