i was looking at upgrading to a 66mm intake wheel and a race cover. someone please explain the benefits of the race cover and is it worth the cost of the upgrade.
a billet wheel is definitely a upgrade over a cast wheel but, would have nothing to do with a race cover.i currently have their "quick diesel". i was told that the billet wheel would spool faster than a regular wheel. the billet wheel has 6 fins and the regular wheel has 7 fins.
