If it is possible, and this occurs, where is the boost going... Is it due to the scavenge effect of the headers... Thus the larger tubes being better due to less effect secondary to a larger area and thus slower velocities... Or am I thinking wrong here... |
Small LSA/duration cams don't hurt you, they work in harmony with the blower's boost.
You're losing boost through the headers.....so you're thinking correctly.
