I am about to go on an open track event, and the rulebook calls for a secondary thortle return spring? Anyone installed one of these? where the heck do I put it? What Spring do I need etc? Pictures are always good.
I talked to the Open Track main guy, and found out this rule only applies to Carb equiped vehicles. The thortle Spring Supras have on the stock throtle body will suffice. FYI this is for the Shelby Club Event Sunday rules.
I'm glad we installed the secondary spring on our t-bodies... it's best to never skip out on safety related items, especially when it's such an inexpensive mod. One thing to remember is that these rules exist for a reason.
