what is the stock throttle body size? and has any one done the flow calulations between the two TB? ">>>would save me time". Also can someone explain WHY you get gains from a larger TB. Im assuming the only way you would gain HP is if the stock TB was actualy a restriction on the amount of air that is sucked/ pushed "however you wanna look at it" into the cylinder. Im no expert so please dont thrash me im just curious....

 

If you really want the low down on it, in no BS terms, email Dan from Fastman, he will tell you exactly what you need to know. Here is his email
