Removing plenum PCV tube Help?
Would it be a benefit to remover the tube in the plenum behind the T/B, it seem that it blocks the inlet air or would it hurt the bottom end.

Apparently some have no confidence in the flow testing and computer simulation GM did for development of the potent LT1 engines; but they may stick a hose barb in the intake runner ahead of the valve body which has not been flow tested in any way.

Every production vehicle is built with compromises, GM, Ford, Dodge, no one blue prints for max performance. That's why every car responds to mod's. Doing things the OE manufacturer cannot due to compromise and to satisfy the masses and regulations.

Looks like it could or would compromise performance and would think by removing it would be a benefit, I have yet to see if anyone has done it and ran a better time MPH 60' and time.

Because its done in conjunction with other mods like removing the intake and smoothing any rough castings in each runner, smoothing the throttle body opening on the intake, smoothing the rough casting lip on the throttle body itself, reducing the length of the pcv tube , all in search of a little better flow to work with a AFE intake, and a borla mid pipe. Easier in, easier out maybe good for 10 to 15 hp. I have done just that along with lower water temps and a big effort in cooling the entire intake path to get 430 rear wheel hp on a fully heat soaked engine compartment dyno pull, which is a realistic conservative 485 hp versus 460 stock. The dyno graph also showed gains as low as 2500 rpm, nothing in the middle and gains from 5000 to 6000 rpm and less of a drop after 6000 rpm. Win, win.
