Vat and Rico,

The WESTECH video's are good, covers the topic of notched plenum vs stock.

Their test mule is quite a lot stronger engine than my configuration but still pretty useful information.

Don't think I have room to add a 1 inch spacer in the ERA, but apparently adding the spacer just about gives the same results as the plenum notch.

Westech has a series of videos that are well made...except for a camera man apparently compulsively moving the camera back and forth.

Thanks, Pete
