Stock throttle body: At what hp is it a restriction?

[hottscennessey]

As the question states, at which point is the stock throttle body a restriction?

Will Neely hit 700+ on it, so I don't think it would be that big of a restriction.

its hard to say. No one has really compared it to say the Q45 tb. Be neat if someone just had say intake, exhaust, mbc. Had a FFIM with stock tb adapter plate that ron can build easy. Dyno before with stock tb on. Pop it off put on the q45 and dyno agian
