Just curious..... >> Not performance per se. It could introduce a rough idle, as the PCV (Positive Crankcase Ventilation) valve would not work correctly. If your PCV doesn't work correctly (with the cap on) having the cap off, *may* increase performance, slightly. The crankcase back pressure in reduced by removing the cap, but the PCV valve normally does a fine job of this. More than anything, you would just leak huge quantities of unburned hyrocarbons into the atmosphere, contributing to smog, increased ground-level ozone, melting of the polar ice-caps, rising sea-levels, fish kills, return of the feared lizard, GODZILLA, and the end of life as we know it. Well, maybe not ALL that. :) Happy Friday, keep your cap on! :) gmbulley cary,nc |
