Re: Must haves with s/c pulley + intake?
My experience with the Code 3 pulley is, yes, you will have to improve cooling.
Brian from Code 3 emailed me the following when I told him that my SC was cutting out from overtemp problems.
"Cooling issues have plagued the 3.2l sc engine since 2002. Remember, we have been modding this engines for quite some time. For years, people didnt understand how there upgraded C32 would lose to cars they shouldnt be in races. The problem was simple, heat soak was shutting the SC off, or causing it to pull a tremendous amount of timing because of the heat, which decreases power. The stock cooling system is not adequate at all to run ANY upgraded boost. When I started developing parts for the C32 two years ago, the first mod I designed was an upgraded HE. The johnson pump on its own will not help much. Even though it flows 50% more than the stock pump, most of it is getting backed up on the inlet side of the intercooler (under the SC), as it flows very poorly. Quite simply, an upgraded HE is one of the first mods I recommend to customers."
