in a while when im on hit hard and let off. I will have a wideband installed in a couple weeks and see how rich it get's, but I don't think running rich for 1 or 2 seconds would effect anything. If anyhting couldn't it help cool down the insides of the cylinders? Also, if it did effect anyhting greatly then howcome alot of drag cars use them .... i'm sure they would have realized if they hurt something by now :)
