Both Pulleys
Re: Both Pulleys
there is only one person who has that setup so only he could answer that. This is from another thread, but take from it what you will. A person just running the SC pulley has said he has zero heat issues, as I have zero issues as well with the 178. This would be a killer combination, just nobody with an SRT6 is so far willing to put his car up for the test, because killer might be literally.
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."

I just got off the phone with Ed Martinez from PSE Superchargers. Great guy to talk to...
The MAX RPM our SC can spin is 20K but that will distroy it quickly.
MAX safe SC RPM is 15.5K to have any chance of a long life.
Let's calculate SC RPM.
Crank / SC = (Ratio) * Engine RPM = SC RPM
155 / 74 = (2.10) * 5.8K = 12,180 SC RPM (Factory)
178 / 74 = (2.41) * 6K = 14,460 SC RPM
181 / 74 = (2.45) * 6K = 14,700 SC RPM
185 / 74 = (2.50) * 6K = 15,000 SC RPM
Code 3 pulley = 65mm (so I've read)
155 / 65 = (2.38) * 6K = 14,280 SC RPM
178 / 65 = (2.74) * 6K = 16,440 SC RPM
Raise your rev-limiter over 6K when you tune and then re-do the math.
BTW - Ed said they re-manufacturer our SC's for $1,495 + Shipping.
They send you a crate that will secure your SC to ship back to them in.
It all depends on risk and if you think your ECU will adjust fuel maps beyond 21 PSI.

I do think a ASP/Code3 combo would work well, just not sure if the ECU will handle the added boost at the upper RPM's.
The down side is $1,495 and some down time for the SRT

Re: Both Pulleys
Just for some who don't know.... When you hear of a C32 running a successful setup, keep in mind their heat exchanger is considerably larger than ours.
It might matter in border-line heat issues.
EDIT: I should also point out that helical superchargers can comfortably go up to 22,000rpm, or so I've heard... So besides heat, I think the S/C itself would do fine.
