After 2 weekends with the new Rw mods 5 port I am really impressed. The timing change really gives it the top end of a 7 port. I am running it in a buggy and it is really fast and smooth. The best part is the internal restrictor really improves mileage. It's the second weekend in a row I was using a 1/2 tank of fuel in a 5 min qual, with the warmup lap it was probably close to 7 minutes. I am not one of those guy's that is really smooth on the gas either, I typically have a 1/4 tank or less left after a qual. Here is a vid of the track we were at, I am not in the vid, just showing that it was a pretty high bite track.
