2 Years ago, I specifically spoke to John from Accufab about this issue. He confirmed that at high RPMs is when the TB becomes effective but not enough for the average person to notice. He also stated that the track is where it will pay for itself.I have pulley, tune, exhaust. Notice a drop in boost over 5000 RPM as HP starts to peak toward 6500 RPM. I figure I'm sucking a vacuum on the air cleaner and you can't compress a vacuum. I just would like some scientifc data that says the Accufab will help restore some of the boost or not. I don't care about bling.
I put the stiffener in the coupler and I'm a little concerned that it reduces the cross section a little too.

That is my understanding.Gentlemen,
The benefit of this piece is marginal with a stock engine. Utilizing a smaller pulley with higher boost levels or with a Whipple supercharger, it becomes more beneficial as a decrease in inlet restriction becomes more important. Unlike the huge monoblade throttle bodies that turn your gas pedal into an on/off switch, the Accufab throttle body offers less intake restriction with smooth and linear throttle response. I would only spend the money to purchase one if I was using it in combination with several other performance enhancements.
