What if I told you that you were only ever using 90% throttle

Check this out. Your throttle might be only opening to 90% or a little better (both my engines' throttles are like this)

Will this, if corrected, free up a little more tq/hp on the dyno?


in my opinion, it won't. As you can notice, the blade(s) are getting 'overturned' at 100% throttle and the inside passage dia of the throttlebody is getting smaller...
