Re: Fastman Oversized 84mm 251 throttle body FS
Larger TB are worthless unless you have corresponding intake, engine and tuning modification. People across all car fields still slap them on though for some reason thinking that simply making the TB hole bigger adds more power.
If it was as simple as widening your TB diameter to increase power.....why wouldn't the factory engineers do it and save expensive machining and development elsewhere?
Heads, headers, exhaust and tune? Sure, then do it. Just slapping it on in your driveway. Nope.
