Hi guys,
i'm thinking of getting a racing 20v engine..
someone told me that a standard 20v blacktop with extractor & autronic only gets 105 hp. on the wheel. and a good racing 20v silvertop will give approx. 145 hp. on the wheel..
i have read bill sherwood site but still doesn't know which way is best..
if someone has any idea will be appriciated..
